安装各种依赖包和环境所需包 …
https://lug.ustc.edu.cn/wiki/mirrors/help/centos
可以把yum源改成上面这个
yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers
php以及连接mysql的组件
yum -y install httpd php php-mysql
apache依赖
yum -y install httpd-manual mod_ssl mod_perl mod_auth_mysql
php依赖
yum -y install php-gd php-xml php-mbstring php-ldap php-pear php-xmlrpc php-bcmath php-snmp lm_sensors lm_sensors-devel perl-DBD-MySQL
yum -y install mysql-connector-odbc mysql-devel libdbi-dbd-mysql mysql mysql-server

yum -y install php-gd php-bcmath elfutils beecrypt php-snmp lm_sensors
yum -y install net-snmp net-snmp-devel net-snmp-utils
yum -y install curl curl-devel
yum -y install fping ##zabbix 使用 fping 替代了 ping 作为 icmp 的工具
mysql修改配置文件，因为yum源安装的是5.1版本，给一个配置模板…模板好像是5.5的

不细说MySQL的部署过程了，大致过程
1、建数据目录、日志目录、tmp目录
2、chown -R mysql.mysql 数据目录、日志目录、tmp目录
3、初始化mysql_install_db –defaults-file=/etc/my.cnf &
4、启动mysqld_safe –defaults-file=/etc/my.cnf &
5、系统建zabbix组合用户groupadd zabbix;useradd -g zabbix -d /home/zabbix -s /sbin/nologin zabbix
6、解压zabbix，编译配置参数说明：
–enable-server 安装 Zabbix Server
–enable-proxy 安装 Zabbix Proxy
–enable-agent 安装 Zabbix Agent
–with-mysql 使用 mysql 做数据库服务器
–with-net-snmp 支持 SNMP
–with-libcurl 支持 curl，用于 web 监控
我不需要网络设备监控，监控机器比较少，所以不用proxy和snmp，编译后的路径按照自己喜好放置吧
./configure –prefix=/usr/local/zabbix –with-mysql –enable-server –enable-agent –with-libcurl
编译完会显示以下信息
Configuration: Detected OS: linux-gnu
Install path: /usr/local/zabbix
Compilation arch: linux Compiler: gcc
Compiler flags: -g -O2 -I/usr/include/mysql -g -pipe -Wp,-D_FORTIFY_SOURCE= -fexceptions -fstack-protector --param=ssp-buffer-size= -m64 -D_GNU_SOURCE -D_FILE_OFFSET_BITS= -D_LARGEFILE_SOURCE -fno-strict-aliasing -fwrapv -fPIC -DUNIV_LINUX -DUNIV_LINUX Enable server: yes

* Now run 'make install' *
* *
* Thank you for using Zabbix! *
* <http://www.zabbix.com> *
***********************************************************
继续make install
7、MySQL建zabbix库、用户
insert into mysql.user(User,Host,Password) values (‘zabbix’,’%’,password(‘zabbix’));
flush privileges;grant all privileges on zabbix.* to ‘zabbix’@’%’;
show grants for zabbix; ##yum装的mysql5.1比较操蛋
create database zabbix
mysql> show grants for zabbix;
+-------------------------------------------------------------------------------------------------------+
| Grants for zabbix@% |
+-------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'zabbix'@'%' IDENTIFIED BY PASSWORD '*DEEF4D7D88CD046ECA02A80393B7780A63E7E789' |
| GRANT ALL PRIVILEGES ON `zabbix`.* TO 'zabbix'@'%' |
+-------------------------------------------------------------------------------------------------------+
2 rows in set (0.00 sec)mysql> GRANT ALL PRIVILEGES ON `zabbix`.* TO 'zabbix'@'%' IDENTIFIED BY PASSWORD '*DEEF4D7D88CD046ECA02A80393B7780A63E7E789'
-> ;
Query OK, 0 rows affected (0.00 sec)mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
8、注意依次导入./database/mysql/schema.sql ./database/mysql/images.sql ./database/mysql/data.sql
mysql -uzabbix -pzabbix zabbix <./database/mysql/schema.sql
mysql -uzabbix -pzabbix zabbix <./database/mysql/images.sql
mysql -uzabbix -pzabbix zabbix <./database/mysql/data.sql
9、检查一下/etc/services里面是否有以下四行，如果没有就加上
zabbix-agent /tcp # Zabbix Agent
zabbix-agent /udp # Zabbix Agent
zabbix-trapper /tcp # Zabbix Trapper
zabbix-trapper /udp # Zabbix Trapper
10、拷贝zabbix目录下的frontend/php内容到http server的主目录下：
cp -r frontends/php/* /var/www/html/zabbix/
11、启动Apache
service httpd start
将 Apache 设置为开机自动启动
chkconfig –add httpd
chkconfig –level 345 httpd on
httpd: Could not reliably determine the server’s fully qualified domain name, using 127.0.0.1 for ServerName
vim /etc/httpd/conf/httpd.conf
找到#ServerName www.example.com:80 把#去掉，再重启apache即可，浏览器访问一下试试
12、修改zabbix_server配置文件
参考博文修改的内容
[root@localhost zabbix-2.0.]# sed -i 's/^DBUser=.*$/DBUser=zabbix/g' /usr/local/zabbix/etc/zabbix_server.conf[root@localhost zabbix-2.0.]# sed -i 's/^.*DBPassword=.*$/DBPassword=111111/g' /usr/local/zabbix/etc/zabbix_server.conf[root@localhost zabbix-2.0.]# cp -r frontends/php /var/www/html/zabbix[root@localhost zabbix-2.0.]# cp misc/init.d/fedora/core/zabbix_server /etc/init.d/[root@localhost zabbix-2.0.]# cp misc/init.d/fedora/core/zabbix_agentd /etc/init.d/[root@localhost zabbix-2.0.]#sed -i 's/BASEDIR=\/usr\/local/BASEDIR=\/usr\/local\/zabbix/g' /etc/init.d/zabbix_server[root@localhost zabbix-2.0.]#sed -i 's/BASEDIR=\/usr\/local/BASEDIR=\/usr\/local\/zabbix/g' /etc/init.d/zabbix_agentd
我修改的内容
LogFile=/tmp/zabbix_server.log
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix
DBSocket=/export/zabbix/mysql_socket/mysql.sock
FpingLocation=/usr/sbin/fping
要安装fping
下载地址：http://fping.org/
安装：
tar -zxvf fping.tar.gz
cd fping/
./configure
make && make install
which fping <- FpingLocation的配置安装这个修改
fping failed: "(null): can't create socket (must run as root?) : Protocol not supported"
/usr/local/sbin/fping: can't create raw socket (must run as root?) : Operation not permitted
登录zabbix用户验证确实zabbix用户无法使用fping，权限问题，修改权限
chown root:root /usr/local/sbin/fping
chmod u+s /usr/local/sbin/fping
如果启动的时候提示pid找不到，那就改一下pid的相关项
然后做一下软连或者加上环境变量
[root@zabbixserver mpm]# cd /bin/
[root@zabbixserver bin]# ln -s /usr/local/zabbix/bin/zabbix_sender zabbix_sender
[root@zabbixserver bin]# ln -s /usr/local/zabbix/bin/zabbix_get zabbix_get
13、修改php.ini配置文件
参考博文修改的内容
[root@localhost ~]#sed -i 's/^\(.*\)date.timezone =.*$/date.timezone = Asia\/Shanghai/g' /etc/php.ini[root@localhost ~]#sed -i 's/^\(.*\)post_max_size =.*$/post_max_size = 16M/g' /etc/php.ini[root@localhost ~]#sed -i 's/^\(.*\)max_execution_time =.*$/max_execution_time = 300/g' /etc/php.ini[root@localhost ~]#sed -i 's/^\(.*\)max_input_time =.*$/max_input_time = 300/g' /etc/php.ini[root@localhost ~]# /etc/init.d/zabbix_server start[root@localhost ~]# /etc/init.d/zabbix_agentd start[root@localhost ~]# /etc/init.d/httpd start
修改完php配置需要重启zabbix_server和apache
可以访问zabbix页面进行配置，下面提示连接不到MySQL
function DBconnect(&$error) {}代码段，代码里面没有指定socket，所以一般不是这块问题。
function DBconnect(&$error) {
global $DB; if (isset($DB['DB'])) {

$error = $dbBackend->getError();
$result = false;
} if (false == $result) {
$DB['DB'] = null;
} return $result;
}
1、mysql.sock文件位置问题
因为MySQL配置的路径各异，sock做个软连过去（上一步自检php环境，按照上面修改php.ini即可，别忘重启apach和zabbix）
cd /var/lib/mysql/ ;ln -s /export/zabbix/mysql_socket/mysql.sock mysql.sock
2、SELinux和iptables影响
service iptables stop
/usr/sbin/sestatus -v ##如果SELinux status参数为enabled即为开启状态
修改/etc/selinux/config 文件将SELINUX=enforcing改为SELINUX=disabled，然后reboot，注意最好先停掉mysql进程
3、测试
ie访问部署的这台机器比如192.168.1.2/zabbix，ie字体小，遨游和chrome好点
然后特么进不去页面，各种检查
zabbix log 有/tmp/zabbix_server.log 和 zabbix_agentd.log
httpd log /var/log/httpd/errlog。。。
然后想起来IE代理这个情况…买了个表
其他页面设置可以参考文章首的第一个链接
问题1：字体问题参考链接
http://blog.chinaunix.net/uid-11121450-id-3296646.html
问题2：页面的历史记录（history）乱码变成???>???>???
安装时在导入三个sql文件时，zabbix数据库中创建的表的字符集是latin1，修改为utf8，如果Zabbix里面没有建主机和监控项就drop databases，配置文件修改如下：
[mysqld] ##这个节点下面增加default-character-set = utf8
http://www.haogongju.net/art/2418891
问题3：启动zabbix_server提示缺失lib模块
[root@zabbixserver lib]# service zabbix_server start
zabbix_server: error while loading shared libraries: libmysqlclient.so.: cannot open shared object file: No such file or directory
[root@zabbixserver lib]# ln -s /usr/local/mysql/lib/libmysqlclient.so. /usr/lib64/
下面的可以忽略
Zabbix自带的mysql监控的配置
因为Zabbix自带的监控脚本取的数据较少，还需要自己改一些东西，所以最后用的mysql_performance_monitor，所以带删除线的这块可以忽略
http://os.51cto.com/art/201104/253006.htm
http://my.oschina.net/zhongjuan/blog/89412
http://www.it165.net/os/html/201210/3677.html
上文中提到的xml和php获取地址
https://www.zabbix.com/wiki/howto/monitor/db/mysql/extensive_mysql_monitoring_including_replication
拿到xml以后，在zabbix中文界面里面的【组态】-【模板】的右边有一个【汇入】，把xml模板导入
php脚本需要放到监控机，配置文件目录/usr/local/zabbix/etc/
根据本机环境。
第一行加入：#!/usr/bin/php
在最后一行加入：?>关闭调试：define('DEBUG',true); 为 define('DEBUG',False);修改日志、数据文件路径：define('LOG',"/tmp/zabbix_".SYSTEM.".log");
define('DAT',"/tmp/zabbix_".SYSTEM.".dat");
define('UTIME',"/tmp/.zabbix_".SYSTEM.".utime");
define('DTIME',"/tmp/.zabbix_".SYSTEM.".dtime");修改：define('SYSTEM','mysql'.(DEBUG ? "-debug" : "")); 为：define('SYSTEM','mysql');打开系统日志功能：//system("zabbix_sender -z $server -i ".DAT." >> ".LOG); 为：system("zabbix_sender -z $server -i ".DAT." >> ".LOG);注释file_put_contents(DAT,"$server $host 10051 ".SYSTEM.".$var $val\n",FILE_APPEND);且下面增加以下文字：
$cmd = "zabbix_sender -c $config_path -k ".SYSTEM.".$var -o $val -vv";
file_put_contents(DAT,"$cmd\n",FILE_APPEND);
exec($cmd);
在zabbix_agentd.conf配置文件中加入
这个php报错还是需要注意的
UserParameter=mysql.daily,php /etc/zabbix/mysql.php daily 用户名 密码
UserParameter=mysql.live,php /etc/zabbix/mysql.php live 用户名 密码daily:每天执行一次。【由zabbix_server轮询发起，默认86640秒即一天 zabbix agent类型 UDP协议】live:按指定时间执行一次。【由zabbix_server轮询发起，默认120秒 zabbix agent类型 UDP协议】php :执行php文件/etc/zabbix/mysql.php:mysql.php文件所在的文件路径用户名 密码：登录mysql数据库的账户与密码重启zabbix_agentd
mysql.php里面还需要zabbix/bin下的部分执行文件的环境变量，否则会报一些错误，具体问题具体分析，修改mysql.php或者php.ini
sh: zabbix_sender: command not found
cd /usr/bin/ ;ln -s /usr/local/zabbix/bin/zabbix_sender zabbix_sender
ln -s /usr/local/zabbix/bin/zabbix_get zabbix_get
报错：
PHP Warning: Division by zero in /usr/local/zabbix/etc/mysql.php on line
PHP Warning: Division by zero in /usr/local/zabbix/etc/mysql.php on line
PHP Warning: Division by zero in /usr/local/zabbix/etc/mysql.php on line
chown zabbix.zabbix /tmp/zabbix_*
mysql.php 监控文件里面的命令执行失败大部分由于授权或者环境变量影响，/tmp下的日志文件属主权限、用户的.bash_profile是否导入，检查php zabbix_sender mysql的环境变量
因为Zabbix提供的监控脚本和监控项不太好用，所以决定使用第三方的一个插件mysql_performance_monitor！！！
【MPM】
1、安装环境
yum install -y perl-libwww-perl perl-File-Which perl-DBD-MySQL perl-Digest-SHA1 perl-Digest-SHA perl-Crypt-SSLeay perl-Time-HiRes
参考地址
http://blog.chinaunix.net/uid-451-id-3338674.html
http://www.fromdual.com/download
2、安装mpm
[root@zabbixserver package]# tar -zxvf mysql_performance_monitor-0.9..tar.gz[root@zabbixserver package]# mv mysql_performance_monitor_agent mpm[root@zabbixserver package]# mv mpm /usr/local/#配置文件，配置详细看下面
[root@zabbixserver package]# vim /etc/zabbix_mpm.conf[root@zabbixserver package]# chown zabbix /etc/zabbix_mpm.conf[root@zabbixserver package]# mkdir /var/log/zabbix[root@zabbixserver package]# touch /var/log/zabbix/FromDualMySQLagent.log[root@zabbixserver package]# chown -R zabbix:zabbix /var/log/zabbix#UserParameter的值修改为：注意mpm配置位置
[root@zabbixserver mpm]# vim /usr/local/zabbix/etc/zabbix_agentd.conf
UserParameter=FromDual.MySQL.check,/usr/local/mpm/FromDualMySQLagent.pl /usr/local/mpm/zabbix_mpm.conf[root@zabbixserver bin]# usermod -G mysql zabbix
3、导入xml模板
修改主机系统名、Zabbix_server/agentd配置文件的必须一致，与zabbix web新建的主机名必须一致
xml模板没必要都导入，可以先将MySQL.mpm（前缀删了），对应agent配置也先加这一个，后期需要可以逐步加模板及监控项
MPM Server的配置（MPM Server监控自己zabbix server的MySQL）
[default]
Type = mysqld
Debug =
LogFile = /var/log/zabbix/FromDualMySQLagent.log
CacheFileBase = /var/log/zabbix/cache/FromDualAgentCache
Username = zabbix
Password = zabbix
MysqlHost = 127.0.0.1
MysqlPort =
ZabbixServer = localhost
Disabled = false
[zabbixserver]
Type = mysqld
MysqlPort =
Modules = mpm innodb mysql process server
PidFile = /export/zabbix/mysql_data/mysql.pid
MPM Agent的配置
Type = mysqld
Debug =
LogFile = /var/log/zabbix/FromDualMySQLagent.log
CacheFileBase = /var/log/zabbix/cache/FromDualAgentCache
Username = zabbix
Password = zabbix
MysqlHost = localhost
MysqlPort =
ZabbixServer = 192.168.201.107
Disabled = false
[cobbler]
Type = mysqld
MysqlPort =
Modules = mpm innodb mysql process server
PidFile = /export/data/mysql/data/mysql.pid
4、报错及分析
（1）、MPM报找不到mysql.pid
#FromDualMySQLagent.log报找不到mysql.pid
:-- ::33.222 - ERR : Cannot read PID file /export/zabbix/mysql_data/mysql.pid. Either file does not exist or I have no read permissions. Are you sure the process is running?#修改一下权限
[root@zabbixserver bin]# usermod -G mysql zabbix
（2）、MPM说某个模块不存在，分析
#报FromDualMySQLinnodb模块不存在
:-- ::33.146 - ERR : Module FromDualMySQLinnodb does not exist.
ERR : Can't locate Digest/SHA.pm in @INC (@INC contains: /usr/local/mpm/lib /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /usr/local/mpm/lib/InnoDbStatus.pm line 9.

#这个问题是因为perl少安装一个perl-Digest-SHA依赖包
下面的斜体部分都属于报错、排错部分，是针对某些非MPM官网包出现的问题，如果是官网下的MPM可以直接忽略…还是踏踏实实官网下载，别论坛或者扒别人的

做了个测试脚本
#!/usr/bin/perl
my $cmd = "zabbix_sender --zabbix-server 127.0.0.1 --port 10051 --host 'zabbix_server' --key FromDual.server.check --value '1'";
system("$cmd >/dev/null 2>&1");
my $ret = $?;
my $code = $ret >> ;
if ( ($ret >> ) == ) { printf "code 0" }
else { printf "code is $code" }
使用zabbix_sender的Item项的type必须是Zabbix trapper，如果是Zabbix agent会一直返回2
[root@localhost cache]# zabbix_sender --zabbix-server 127.0.0.1 --port 10051 --host 'zabbixserver' --key FromDual.server.check --value '1' ;echo $?
info from server: "processed: 0; failed: 1; total: 1; seconds spent: 0.000028"
sent: ; skipped: ; total: 1
2
说明还是有问题，继续排查中…
返回值2是shell内建命令使用错误
https://www.zabbix.com/documentation/2.0/manpages/zabbix_sender zabbix_sender的说明
因为在zabbix web页面中，没有模板是符合 FromDual.server.check的，所以他会报错
一定注意模板的重要性，会遇到两个比较常见的问题
1、就是上面的check失败，/var/log/zabbix/FromDualMySQLagent.log 报：
:-- ::19.099 - INFO: FromDual Performance Monitor for MySQL (0.9.) run started.
:-- ::19.130 - WARN: localhost, , zabbixserver
:-- ::19.130 - WARN: Connection to zabbix server failed (rc=)!
:-- ::19.130 - INFO: FromDual Performance Monitor for MySQL run finshed (rc=).
2、zabbix web页面主机监控状态会显示为红色的Z，并提示：
Received empty response from Zabbix Agent at [192.168.10.217]. Assuming that agent dropped connection because of access permission
这就是Server自己的模板确实造成，模板要和agent监控的模块匹配
决定改下FromDualMySQLagent.pm的checkConnectionToZabbixServer模块默认的$key值
# This tag does NOT exist in templates!!!
my $lKey = 'FromDual.server.check';
改为
# This tag does NOT exist in templates!!!
my $lKey = 'FromDual.MySQL.mpm.mpm_version';
但是必须在/etc/zabbix_mpm.cnf的Modules中加入mpm
执行zabbix_sender测试
[root@zabbixserver cache]# zabbix_sender --zabbix-server 127.0.0.1 --port 10051 --host 'zabbixserver' --key FromDual.MySQL.mpm.mpm_version --value '1' ;echo $?
info from server: "processed: 1; failed: 0; total: 1; seconds spent: 0.000042"
sent: ; skipped: ; total:
但是！FromDualMySQLagent.log 然后开始报：
:-- ::26.283 - INFO: FromDual Performance Monitor for MySQL (0.9.) run started.
:-- ::26.301 - ERR : Load of cache file failed. rc=
:-- ::26.301 - INFO: FromDual Performance Monitor for MySQL run finshed (rc=).
what the fuck…
sendCachedData.pm的sendCachedData的
my $cmd = "$exe --zabbix-server $pServer --port $pPort --input-file $main::gParameter{'CacheFile'} --with-timestamps";
my $ret = $?;
$rc = ;
if ( $main::gParameter{'Debug'} == DBG ) { &FromDualMySQLagent::mylog($main::gParameter{'LogFile'}, DBG, " (ret=$ret / rc=$rc)."); } if ( $ret == ) {
# Do not delete Cache File but just set it back to zero again
&FromDualMySQLagent::clearCacheFile($main::gParameter{'CacheFile'});
}
else {
&FromDualMySQLagent::mylog($main::gParameter{'LogFile'}, ERR, " Load of cache file failed. rc=$rc");
}
测试：
[root@zabbixserver cache]# zabbix_sender --zabbix-server 127.0.0.1 --port 10051 --input-file /var/log/zabbix/cache/FromDualAgentCache.zabbixserver.cache --with-timestamps ;echo $?
Sending failed. Use option -vv for more detailed output.
发现个问题，每次监控的mpm模块会把FromDualAgentCache.zabbixserver.cache文件中最后写入个空行，导致zabbix_sender读取失败
用其他模板中的模块去让他check即可解决
/usr/local/mpm/FromDualMySQLagent.pl /etc/zabbix_mpm.conf
在部署zabbix_agentd的时候报以下错误：
:-- ::11.745 - INFO: FromDual Performance Monitor for MySQL (0.9.) run started.
:-- ::11.957 - ERR : Cannot read PID file /export/data/mysql/data/mysql.pid. Either file does not exist or I have no read permissions. Are you sure the process is running?
:-- ::11.958 - INFO: FromDual Performance Monitor for MySQL run finshed (rc=).
解决方法usermod -G mysql zabbix
以下错误可以使用软连
:-- ::50.366 - INFO: FromDual Performance Monitor for MySQL (0.9.) run started.
:-- ::50.404 - ERR : DBI connect with database=mysql, host=localhost, port= and user=zabbix failed: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

:-- ::50.414 - INFO: FromDual Performance Monitor for MySQL run finshed (rc=).
mkdir -p /var/lib/mysql/ ;ln -s /export/data/mysql/tmp/mysql.sock mysql.sock
例如mkdir -p /var/lib/mysql/;cd /var/lib/mysql/ ;ln -s /export/data/mysql/tmp/mysql.sock mysql.sock
4、总结
上面基本上能遇到的问题都遇到了，总结一下：
1、Zabbix部署没什么难度，注意MySQL和php配置与Zabbix的一致即可，注意环境变量，若报找不到sock或者pid文件，但是找不到相关配置，最后办法可以ln做软连
2、mysql.php作为Zabbix自己的MySQL监控插件和Zabbix官网的监控模板不是很好用，推荐用MPM。MPM的原理就是通过/usr/local/mpm/FromDualMySQLagent.pl读取配置文件/etc/zabbix_mpm.conf中所需要的模块，然后调用/usr/local/mpm/lib下的各个模块读MySQL运行参数
3、别TM从什么网盘或者什么参考论坛下插件，一定要从第三方软件官网！查了一圈结果是MPM包的问题，官网的配上就好使
4、MPM不好使可以用zabbix_sender在agentd机器测试是否可以成功，MPM脚本中很多环节是依靠zabbix_sender的检查
5、在zabbix_server端可以用zabbix_get检查是否可以连通agentd端
6、MPM配置中的Modules中加上MPM他就会自动刷新，否则只能把脚本加到crontab中一分钟取一次数（http://blog.chinaunix.net/uid-451-id-3338674.html中最后“关于mpm的刷新频率”）
7、主机名、MPM和zabbix配置中的与zabbix web界面的要一致
8、MPM中Modules的模块一定要在zabbix web中导入相对应模板，否则会出现（下面仅实例，记得这个返回码是1）
[root@zabbixserver cache]# zabbix_sender --zabbix-server 127.0.0.1 --port --input-file /var/log/zabbix/cache/FromDualAgentCache.zabbixserver.cache --with-timestamps ;echo $?
info from server: "processed: 123; failed: 234; total: 357; seconds spent: 0.000042"
sent: ; skipped: ; total:
【Zabbix监控项目触发的动作，调用msmtp发邮件比较麻烦，使用msmtp配合mutt十分方便】
Zabbix监控动作传出的数据定义
$1 收件人 recipient=email@explain.com
$2 标题 subject=’服务器cobbler-MySQL server is down on cobbler的故障’
$3 邮件内容message=’MYSQL down’
【msmtp】
1、msmtp邮件插件下载地址：
http://sourceforge.net/projects/msmtp/files/msmtp/1.4.32/
[root@zabbixserver ~]# tar jxvf msmtp-1.4..tar.bz2
[root@zabbixserver ~]# cd ./msmtp-1.4.
[root@zabbixserver msmtp-1.4.]# ./configure --prefix=/usr/local/bin/msmtp ;make && make install ;
[root@zabbixserver etc]# cd /usr/local/etc/
[root@zabbixserver etc]# ln -s /export/zabbix/msmtprc msmtprc
[root@zabbixserver etc]# msmtp -P
2、msmtp配置参考：
http://www.docin.com/p-471069369.html
配置示例（使用时把配置文件的所有注释删掉）
[root@zabbixserver ~]# vim /usr/local/etc/msmtprc
account email@explain.com
host smtp.explain.com
port #特殊需修改，默认25
from email@explain.com
auth login
tls off
user username
password passwd_user
account default:email@explain.com
logfile /var/log/zabbix/zabbix_msmtp.log
touch /var/log/zabbix/zabbix_msmtp.log
chmod 600 .msmtprc
msmtp -P 命令测试msmtp配置是否正确
loaded system configuration file /usr/local/etc/msmtprc
loaded user configuration file /root/.msmtprc
falling back to default account
using account default from /root/.msmtprc
host = smtp.explain.com
port =
timeout = off
protocol = smtp
domain = localhost
auth = LOGIN
user = username
password = *
passwordeval = (not set)
ntlmdomain = (not set)
tls = off
tls_starttls = on
tls_trust_file = (not set)
tls_crl_file = (not set)
tls_fingerprint = (not set)
tls_key_file = (not set)
tls_cert_file = (not set)
tls_certcheck = on
tls_force_sslv3 = off
tls_min_dh_prime_bits = (not set)
tls_priorities = (not set)
auto_from = off
maildomain = (not set)
from = @qq.com
dsn_notify = (not set)
dsn_return = (not set)
keepbcc = off
logfile = /var/log/zabbix/zabbix_msmtp.log
syslog = (not set)
aliases = (not set)
reading recipients from the command line
上面说明检查配置成功，如果有报错，对应报错修改配置内容或者配置文件所在位置
3、测试
一般telnet不通的，比如telnet smtp.sina.com 25失败的，那先看看端口是不是受限了
msmtp email@explain.com 回车后输入内容，然后Ctrl+d尝试发送邮件，观察/var/log/zabbix/zabbix_msmtp.log
4、脚本
#! /bin/sh
DEBUG=
if [ $DEBUG -gt ]
then
exec >>/export/zabbix/cache/zabbix_msmtp.log
set -x
fi
FROM='email@explain.com'
MSMTP_ACCOUNT='email@explain.com'
# Parameters (as passed by Zabbix):
# $ : Recipient
# $ : Subject
# $ : Message
recipient=$
subject=$
message=$
date=`date --rfc-`
sed 's/$/\r/' <<EOF | /usr/local/msmtp/bin/msmtp -C /usr/local/etc/msmtprc --account $MSMTP_ACCOUNT $recipient
From: <$FROM>
To: <$recipient>
Subject: $subject
Date: $date
$message
EOF
报警邮件有中文的话，foxmail收到邮件标题和内容都会是乱码，foxmail自动识别不好用，outlook比较好，但是太占用内存，网易的邮箱也还好，内容可以自己匹配字符集，但是标题也还是乱码。
可能遇到的报错
msmtp: /usr/local/etc/msmtprc: must have no more than user read/write permissions
把配置文件的权限修改一下
[root@zabbixserver etc]# chown zabbix,zabbix msmtprc
[root@zabbixserver etc]# chmod og-rwx msmtprc
[root@zabbixserver etc]# chmod u-wx msmtprc
建议把脚本放在zabbix_server.cnf默认的路径下
编译的path: zabbix/share/zabbix/alertscripts
然后授权zabbix
[root@zabbixserver alertscripts]# chown zabbix,zabbix msmtp.sh
5、测试
进入zabbix用户下，调用上述脚本测试，如果进不去zabbix用户，执行
[root@zabbixserver /]# usermod -s /bin/bash zabbix
【mutt】（mutt没有试用成功）
mutt邮件处理框图
http://blog.chinaunix.net/uid-20543672-id-3349607.html
我用的yum安装mutt
参考msmtp这里面的改配置文件
http://www.docin.com/p-471069369.html
[root@zabbixserver /]# vim muttrc
[root@zabbixserver /]# cd /root/
[root@zabbixserver ~]# ln -s /export/zabbix/muttrc .muttrc
1、mutt配置muttrc内容
set use_from=yes
set realname="email@explain.com"
set sendmail="/path/msmtp"
set editor="vi"
set from="email@explain.com"
如果不加set from=”email@explain.com” 会报下面的错误
[root@localhost export]# echo "hahahaha" | mutt -s "MySQL down" email@explain.com
msmtp: the server did not accept the mail
msmtp: server message: 550 5.7.1 Client does not have permissions to send as this sender
msmtp: could not send mail (account default from /root/.msmtprc)
Error sending message, child exited 69 (Service unavailable.).
Could not send the message.
2、脚本配置
脚本路径是zabbix_server配置文件控制的，如下，所以需要把脚本放到这个目录下
AlertScriptsPath=/usr/bin/
3、脚本
#!/bin/bash
echo "$3" | mutt -s "$2" $1
【Zabbix邮件报警设置】
邮件报警，参考：
报警脚本 -> http://waringid.blog.51cto.com/65148/1142579/ <- 不太好用，用mutt自己写个简单的
配置 ->http://www.centoscn.com/CentosServer/log/2013/0807/1168.html
MPM对于MySQL实例是否存活的alive的监控是基于自己MPM脚本的，但是如果MySQL已经down了，MPM采集不到数据，MPM脚本会报错而sender不出来数据，导致拿不到实际MySQL状态
自己建模板、项目、触发器，利用zabbix的net模块的端口监控MySQL是否存活（存活状态是否健康还需要其他类型监控），参考链接：
http://www.linuxidc.com/Linux/2013-05/83780.htm
选择一个用户组（可以先新建一个组，并把用户加到这个组）
用户的邮箱地址可以在点击在用户-示警媒介中添加和配置
新建示警媒介类型（管理-示警媒介类型-创建媒体类型）
在动作中添加群组以及动作行为（组态-动作-操作）切记配置完点击更新，再点击存档
【部署客户端】
客户端部署比较简单，因为在server这边编译时候已经带了客户端，可以直接把server这边的客户端打个包，复制到监控机。上面示例中的mpm配置是用zabbixserver自己mysql做的一个配置，可以参考上面的配置。
##最好先检查一下server与agent间网络是否通##server这边打好包，做分发
[root@zabbixserver ~]# cd /usr/local/
[root@zabbixserver local]# cp /path/zabbix-2.2./misc/init.d/fedora/core/zabbix_* zabbix/
[root@zabbixserver local]# tar -zcvf ./zabbix.tar.gz zabbix/

[root@ip path]# chown -R zabbix:zabbix /path/zabbix/##zabbix_agentd启了以后看看日志，是否有报错，只要rc不等于0就是有问题
【定制监控项目】
触发器语法：http://www.cnblogs.com/jiangxu67/p/3990372.html
MySQL主从关系的结构中，从库每天有备份计划，添加一个备份计划结果和备份文件大小的监控
先创建一个模板，例如名称：MySQL.backup_status。把一台测试机加入到模板里面
建一个应用集：MySQL Backup
建一个监控项：MySQL Backup Status
存档以后，在已经添加该模板的主机上给zabbix_server发送测试数据：
[root@cobbler dumps]# zabbix_sender --zabbix-server 192.168.201.107 --port --host 'cobbler' --key MySQL.backup_status --value '' ;echo $?
info from server: "processed: 1; failed: 0; total: 1; seconds spent: 0.000034"
sent: ; skipped: ; total:
从监控界面查看效果
添加触发器：
给zabbix_server发送测试数据：
[root@cobbler dumps]# zabbix_sender --zabbix-server 192.168.201.107 --port --host 'cobbler' --key MySQL.backup_status --value '' ;echo $?
info from server: "processed: 1; failed: 0; total: 1; seconds spent: 0.000027"
sent: ; skipped: ; total:
查看效果，此时“类型”选项中选触发器也可以，如图2：
触发器的报警状态是闪烁的，在Zabbix WEB首页显示会更明显：
…弱弱的表示死锁的报警忽略，原因是那篇“MySQL锁和隔离级别浅析分析”测试时候导致的，显示绿色表示死锁问题已恢复。
回来继续说自制这个监控项，可以在主机MySQL定时备份计划部分脚本中多加一个备份结果判断，正常就执行上面zabbix_sender的命令把–value ‘1’ 的状态发给zabbix_server反之发送个0，具体发什么定义什么自己定吧…上面例子和系统定义的返回码弄反了。
后期维护：
1、zabbix数据会慢慢增长，history和history_uint表的数据会很大，尤其是history_uint，可以根据下面网址的方法清理数据，也可以根据自身需要truncate这张表。
