nginx实现动静分离的方法示例

本文主要介绍了nginx实现动静分离的方法示例,具有一定的学习价值,具体如下

环境:

系统/主机名 ip地址 服务
redhat8 :server1 192.168.244.131 nginx
redhat8:server2 192.168.244.133 lnmp
content7:node3 192.168.244.142 httpd

在三台主机上关闭防火墙

[root@server1 ~]# systemctl stop firewalld
[root@server1 ~]# systemctl disable firewalld
[root@server1 ~]# vim /etc/selinux/config 
selinux=disabled

在server1上部署nginx

[root@server1 opt]# cat nginx.sh 
#!/bin/bash

if [ $uid -ne 0 ];then
        echo "please use administrator account"
        exit
fi

dir_b=/var/log
dir_c=nginx-1.20.1

if [ ! -d $dir_b/nginx ];then
        mkdir -p $dir_b/nginx
fi
chown -r nginx.nginx $dir_b/nginx

yum -y install pcre-devel openssl openssl-devel gd-devel gcc gcc-c++  make
yum -y groups mark install 'development tools'

id nginx &>/dev/null 
if [ $? -ne 0 ];then
        useradd -r -m -s /sbin/nologin nginx
fi

tar xf bag/$app_a -c $dir_a

cd  $dir_a/$dir_c
if [ ! -d $dir_a/nginx ];then
        ./configure \
                --prefix=$dir_a/nginx \
