环境：（nginx、apache的web服务已经配置好）
NGINX负载服务器：172.28.95.112
NGINX:172.28.95.113
APACHE:172.28.95.115
负载服务器配置：

[root@LNMP conf]# egrep -v "#|^$" nginx.conf
worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    upstream www.t4x.org { 
      server  172.28.95.113:80;     #nginx服务器
      server  172.28.95.115:80;     #Apache服务器
} 
server{ 
    listen 80; 
    server_name www.t4x.org; 
    location / { 
        proxy_pass         http://www.t4x.org; 
        proxy_set_header   Host             $host; 
        proxy_set_header   X-Real-IP        $remote_addr; 
        proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for; 
    } 
}
}

[root@LNMP conf]# egrep -v "#|^$" nginx.conf

worker_processes 1;

events {

worker_connections 1024;

}

http {

include mime.types;

default_type application/octet-stream;

sendfile on;

keepalive_timeout 65;

upstream www.t4x.org {

server 172.28.95.113:80; #nginx服务器

server 172.28.95.115:80; #Apache服务器

}

server{

listen 80;

server_name www.t4x.org;

location / {

proxy_pass http://www.t4x.org;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

}

测试效果：

[root@lnmp bbs]# echo 172.28.95.113 >index.html    #LNMP环境，其中index.html的内容是172.28.95.113
[root@Apache-PHP bbs]# echo "172.28.95.115">index.html     #LAP环境，其中index.html内容是172.28.95.115
[root@lnmp bbs]# /usr/local/nginx/sbin/nginx -s stop    #关闭LNMP环境的web服务，伪装web服务器宕机
显示效果为：172.28.95.113
[root@lnmp bbs]# /usr/local/nginx/sbin/nginx    #启动web
[root@Apache-PHP bbs]# /usr/local/apache/bin/apachectl -k stop    #关闭apache的web服务
显示效果为：172.28.95.113
当两台服务器都宕机以后显示：502 Bad Gateway
