LVS+Heartbeat 高可用集群方案操作步骤详解(4)

由于在ldirectord.cf文件中配置了"fallback=127.0.0.1:80 gate", 即当后端realserver都发生故障时, 客户端的访问请求将转发到LVS的HA节点自身的80端口上
 
[root@ha-master ~]# rpm -ivh
[root@ha-master ~]# yum install nginx
 
realserver01的nginx配置
[root@ha-master ~]# cd /etc/nginx/conf.d/
[root@ha-master conf.d]# cat default.conf
[root@ha-master conf.d]# >/usr/share/nginx/html/index.html
[root@ha-master conf.d]# vim /usr/share/nginx/html/index.html
Sorry, the access is in maintenance for the time being. Please wait a moment.
 
[root@ha-master conf.d]# /etc/init.d/nginx start
Starting nginx:                                            [  OK  ]
[root@ha-master conf.d]# lsof -i:80
COMMAND  PID  USER  FD  TYPE DEVICE SIZE/OFF NODE NAME
nginx  31944  root    6u  IPv4  91208      0t0  TCP *:http (LISTEN)
nginx  31945 nginx    6u  IPv4  91208      0t0  TCP *:http (LISTEN)
 
访问  或者
访问结果为"Sorry, the access is in maintenance for the time being. Please wait a moment."

6) 启动heartbeat服务 (两个HA节点都要操作)
