Nginx(“engine x”) 是一款是由俄罗斯的程序设计师 Igor Sysoev 所开发高性能的 Web 和反向代理服务器，也是一个 IMAP/POP3/SMTP 代理服务器。在高连接并发的情况下，Nginx 是 Apache 服务器不错的替代品。

系统平台：Red Hat Enterprise Linux Server release 7.3 (Maipo)

内核版本：3.10.0-514.el7.x86_64

yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel

PCRE 作用是让 Ngnix 支持 Rewrite 功能。

Red Hat Enterprise Linux 7.3 下 Nginx 安装

/usr/local/nginx/sbin/nginx -c /usr/local/nginx/sbin/nginx/nginx.conf # 加载指定配置文件启动

/usr/local/nginx/sbin/nginx -s reload # 重新载入配置文件

/usr/local/nginx/sbin/nginx -s reopen # 重启 Nginx

/usr/local/nginx/sbin/nginx -s stop # 停止 Nginx

echo “/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf” >> /etc/rc.local

2、添加到 service 服务

touch /etc/init.d/nginx

chmod 755 nginx // 修改脚本文件 nginx 的权限

chkconfig –add nginx // 将脚本文件加入 chkconfig 中

chkconfig –level 35 nginx on // 设置 nginx 开机在 3 和 5 级别自动启动

nginx 文件内容如下：

#!/bin/sh
#
# nginx – this script starts and stops the nginx daemon
#
# chkconfig: – 85 15
