Centos7.x编译安装Nginx教程

安装Nginx

Nginx安装需要安装一系列支持，其中包含gcc、pcre、zlib、openssl

Nginx是C语言开发，所以需要gcc支持

[root@localhost ~]#     yum install -y gcc gcc-c++

[root@localhost ~]#    yum install -y pcre pcre-devel

[root@localhost ~]#    yum install -y zlib zlib-devel

[root@localhost ~]#     yum -y install openssl openssl-devel

[root@localhost ~]#     wget http://nginx.org/download/nginx-1.16.0.tar.gz #版本自己挑选

[root@localhost ~]#     tar -zxvf nginx-1.16.0.tar.gz               #解压           

[root@localhost ~]#     cd nginx-1.16.0/                                #进入nginx目录

[root@localhost ~]#     ./configure                                       

[root@localhost ~]#     make

[root@localhost ~]#     make install                                      安装完成

[root@localhost ~]#     /usr/local/nginx/conf/nginx               #启动nginx

[root@localhost ~]#     pkill -9 nginx                                    强制关闭nginx

下面将nginx写入系统服务

[root@localhost ~]#     cd /etc/init.d/

[root@localhost ~]#    vim nginx                                          填写代码

#! /bin/sh

# chkconfig: 2345 55 25

# Description: Startup script for nginx webserver on Debian. Place in /etc/init.d and

# run 'update-rc.d -f nginx defaults', or use the appropriate command on your

# distro. For CentOS/Redhat run: 'chkconfig --add nginx'

保存，退出

[root@localhost ~]#     chmod + x /etc/init.d/nginx （或chmod 755 /etc/init.d/nginx） 

#加权限

[root@localhost ~]#     chkconfig --add nginx        #注册为服务

[root@localhost ~]#     chkconfig nginx on             #设置为开机启动

[root@localhost ~]#     service nginx start              #启动

[root@localhost ~]#     service nginx stop              #停止

[root@localhost ~]#     service nginx restart           #重启

[root@localhost ~]#     service nginx reload            #重新载入   命令使用正常
