NGINX反向代理-LANMP配置

标签：backup

实验环境：

NGINX                CentOS 7.2x86_64            IP：172.16.253.94

LAMP                 CentOS 6.7x86_64            IP：192.168.1.20

测试端              CentOS 7.2x86_64            IP：172.16.251.138

构建LAMP：

[root@localhost ~]# iptables -F
[root@localhost ~]# setenforce 0
[root@localhost ~]# yum -y install httpd php php-mysql mysql-server

启动服务：

[root@localhost ~]# service httpd restart

[root@localhost ~]# service httpd mysql

[root@localhost ~]# echo "Backup Server 1" >> /var/www/html/index.html

安装NGINX：

[root@pxe94 ~]# iptables -F
[root@pxe94 ~]# setenforce 0

[root@pxe94 ~]# yum -y install nginx-1.10.1-1.el7.ngx.x86_64.rpm

[root@pxe94 ~]# rpm -ql nginx

启动服务：

[root@pxe94 ~]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
[root@pxe94 ~]# nginx

[root@pxe94 ~]# ss -tnl
State      Recv-Q Send-Q      Local Address:Port                     Peer Address:Port             
LISTEN     0      128                     *:80                                  *:*  

反向代理至后端LAMP：

[root@pxe94 ~]# vim /etc/nginx/conf.d/default.conf

server {

   listen       80;

   server_name  localhost;

   location / {

       root   /usr/share/nginx/html;

       index  index.html index.htm;

       proxy_pass http://192.168.1.20;             //转发至后端服务器

    }

   error_page   500 502 503 504  /50x.html;

   location = /50x.html {

       root   /usr/share/nginx/html;

}

[root@pxe94 ~]# nginx -s reload

客户端测试：

[root@station138 ~]# curl http://172.16.253.94
Backup Server 1

设定发往后端主机请求报文首部的值：

[root@pxe94 ~]# vim /etc/nginx/conf.d/default.conf

server {

    省略部分…

    proxy_set_header X-IP $remote_addr;

    省略部分…

}

[root@pxe94 ~]# nginx -s reload

[root@localhost ~]# vim /etc/httpd/conf/httpd.conf

省略部分…

LogFormat "%{X-IP}i %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined

省略部分…

[root@localhost ~]# service httpd restart

测试后查看日志：

[root@localhost ~]# tail /var/log/httpd/access_log

代理PHP动态页面：

[root@pxe94 ~]# vim /etc/nginx/conf.d/default.conf

省略部分…

location ~* \.php$ {

        proxy_pass http://192.168.1.20;            

    }

省略部分…

[root@pxe94 ~]# nginx -s reload

[root@localhost ~]# vim /var/www/html/test.php

<?php
        phpinfo();
?>
