配置檔案：
2 user nginx nginx;
43 location / {
44 root html;
45 index index.html index.htm;
46 if ($request_uri ~* \.html$){
47 proxy_pass http://htmlservers;
48 }
49 if ($request_uri ~* \.php$){
50 proxy_pass http://phpservers;
51 }
52 proxy_pass http://picservers;
53 }
123 upstream htmlservers { #定義負載均衡伺服器組名稱
124 server 192.168.199.4:80;
125 server 192.168.199.5:80;
126 }
127 upstream phpservers{
128 server 192.168.199.4:80;
129 server 192.168.199.5:80;
130 }
131 upstream picservers {
132 server 192.168.199.4:80;
133 server 192.168.199.5:80;
134 }
135 }
[[email protected] ~]# ln -s /usr/local/nginx/sbin/* /usr/bin/
[[email protected] ~]# nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[[email protected] ~]# nginx -s reload
配置後端伺服器（tiandong64和tiandong65上面配置一樣）：
[[email protected] ~]# yum install php httpd -y
[[email protected] ~]# yum -y install php httpd -y
[[email protected] ~]# cd /var/www/html/
[[email protected] html]# more index.html
192.168.199.4
[[email protected] html]# more test.php
192.168.199.4
<?php
phpinfo();
?>
[[email protected] html]#
[[email protected] html]# ll
total 12
-rw-r--r-- 1 root root 14 Mar 20 00:24 index.html
-rw-r--r-- 1 root root 790 Dec 24 2018 pic.PNG
-rw-r--r-- 1 root root 35 Mar 20 00:25 test.php
重啟Apache服務：
[[email protected] ~]# /etc/init.d/httpd restart
[[email protected] ~]# /etc/init.d/httpd restart
測試一下html頁面：
[[email protected] ~]# curl 192.168.199.3
192.168.199.5
[[email protected] ~]# curl 192.168.199.3
192.168.199.4
[[email protected] ~]# curl 192.168.199.3
192.168.199.5
[[email protected] ~]# curl 192.168.199.3
192.168.199.4
測試php頁面：
