全新linux中通过编译方式安装nginx

先去官网下载linux.tar.gz包 http://nginx.org/en/download.html 传到linxu中解压tar包在软件包nginx-1.15.9目录下对NGINX进行配置 ./configure –sbin-path=/usr/local/nginx/nginx –conf-path=/usr/local/nginx/nginx.conf –pid-path=/usr/local/nginx/nginx.pid –with-http_ssl_module –with-http_stub_status_module –with-stream执行以上命令，提示这个信息：说明没有安装编译器
checking for OS
 + Linux 3.10.0-957.el7.x86_64 x86_64
checking for C compiler … not found./configure: error: C compiler cc is not found解决：yum -install gcc在执行以上命令提示这个信息
./configure: error: SSL modules require the OpenSSL library.
You can either do not enable the modules, or install the OpenSSL library
into the system, or build the OpenSSL library statically from the source
with nginx by using –with-openssl=<path> option.解决：yum -y install openssl openssl-devel 配置执行成功：

编译安装：make install到NGINX目录下启动：./nginx提示以下信息：
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] still could not bind()原因：可能是进程已经启动，或者是端口被占用
解决方式：先查看进程是否启动：ps -ef |grep nginx。如未启动，就是原因二。
原因二解决方式：到安装目录下打开配置文件：vi nginx.conf。将修改为8080，再次启动即可启动成功后浏览器中输入ip和端口访问。
提示“无法访问此网站”
原因：linux中启动了防火墙，可通过：systemctl status firewalld命令查看防火墙状态
解决方式：systemctl stop firewalld 使用该命令禁用防火墙
再次访问ok
