我linux服务器上是这样启动的：
cd /tool/redis/redis-3.2.8/src //先到redis的src目录./redis-server ../redis.conf //然后根据配置文件启动 是后台方式启动 ps -aux | grep redis //查看进程
kill -9 14172 //杀死进程
redis-cli -a root //客户端带密码启动
127.0.0.1:6379> config get requirepass //查看密码
config set requirepass abcdefg //设置密码 临时的，redis重启就没有了
127.0.0.1:6379> auth root //指定密码
第一步：下载redis安装包
wget http://download.redis.io/releases/redis-4.0.6.tar.gz
第二步：解压压缩包 tar -zxvf redis-4.0.6.tar.gz
[root@iZwz991stxdwj560bfmadtZ local]# tar -zxvf redis-4.0.6.tar.gz
第三步：yum安装gcc依赖 yum install gcc
[root@iZwz991stxdwj560bfmadtZ local]# yum install gcc遇到选择,输入y即可<br><br><br>
第四步：跳转到redis解压目录下 cd redis-4.0.6
[root@iZwz991stxdwj560bfmadtZ local]# cd redis-4.0.6
第五步：编译安装 make MALLOC=libc
[root@iZwz991stxdwj560bfmadtZ redis-4.0.6]# make MALLOC=libc
注意：make命令执行完成编译后，会在src目录下生成6个可执行文件，分别是redis-server、redis-cli、redis-benchmark、redis-check-aof、redis-check-rdb、redis-sentinel。
第六步：安装Redis 进去src目录
[root@iZwz991stxdwj560bfmadtZ redis-4.0.6]# cd src && make install CC Makefile.depHint: It's a good idea to run 'make test' ;) INSTALL install
INSTALL install
INSTALL install
INSTALL install
INSTALL install
第七步：测试是否安装成功 先切换到redis src目录下
[root@iZwz991stxdwj560bfmadtZ redis-4.0.6]# cd src
直接启动redis
./redis-server
[root@iZwz991stxdwj560bfmadtZ src]# ./redis-server

如上图：redis启动成功，但是这种启动方式需要一直打开窗口，不能进行其他操作，不太方便。
按 ctrl + c可以关闭窗口。
2、以后台进程方式启动redis
第一步：修改redis.conf文件
将
daemonize no
修改为
daemonize yes
第二步：指定redis.conf文件启动
./redis-server /usr/local/redis-4.0.6/redis.conf
第三步：关闭redis进程
首先使用ps -aux | grep redis查看redis进程
[root@iZwz991stxdwj560bfmadtZ src]# ps -aux | grep redis
root 18714 0.0 0.1 141752 2008 ? Ssl 13:07 0:00 ./redis-server 127.0.0.1:6379
root 18719 0.0 0.0 112644 968 pts/0 R+ 13:09 0:00 grep --color=auto redis
使用kill命令杀死进程
[root@iZwz991stxdwj560bfmadtZ src]# kill -9 18714
第七步：设置redis开机自启动
在/etc目录下新建redis目录 mkdir redis
[root@iZwz991stxdwj560bfmadtZ etc]# mkdir redis
将/usr/local/redis-4.0.6/redis.conf 文件复制一份到/etc/redis目录下，并命名为6379.conf
[root@iZwz991stxdwj560bfmadtZ redis]# cp /usr/local/redis-4.0.6/redis.conf /etc/redis/6379.conf
将redis的启动脚本复制一份放到/etc/init.d目录下
[root@iZwz991stxdwj560bfmadtZ init.d]# cp /usr/local/redis-4.0.6/utils/redis_init_script /etc/init.d/redisd
设置redis开机自启动
先切换到/etc/init.d目录下
然后执行自启命令
[root@iZwz991stxdwj560bfmadtZ init.d]# chkconfig redisd on
service redisd does not support chkconfig
看结果是redisd不支持chkconfig
解决方法：
使用vim编辑redisd文件，在第一行加入如下两行注释，保存退出
# chkconfig: 2345 90 10
# description: Redis is a persistent key-value database
注释的意思是，redis服务必须在运行级2，3，4，5下被启动或关闭，启动的优先级是90，关闭的优先级是10。
再次执行开机自启命令，成功
[root@iZwz991stxdwj560bfmadtZ init.d]# chkconfig redisd on
现在可以直接已服务的形式启动和关闭redis了
启动：
service redisd start
[root@izwz991stxdwj560bfmadtz ~]# service redisd start
Starting Redis server...
2288:C 13 Dec 13:51:38.087 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
2288:C 13 Dec 13:51:38.087 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=2288, just started
2288:C 13 Dec 13:51:38.087 # Configuration loaded
关闭：
service redisd stop
[root@izwz991stxdwj560bfmadtz ~]# service redisd stop
Stopping ...
Redis stopped

[root@iZwz991stxdwj560bfmadtZ ~]# service redisd start
/var/run/redis_6379.pid exists, process is already running or crashed
