nginx集群的搭建

1.创建两个虚拟机：192.168.88.3（设为master），192.168.88.4（设为backup）

2.在两个虚拟机上都安装nginx，jdk，keepalived

安装keepalived:

yum install keepalived  安装keepalived   yum:联网安装
rpm -q -a keepalived  检查是否安装keepalived  ps -ef | grep keepalived

3.修改/etc/keepalied/下的keepalived.conf文件。

4.把nginx_check.sh拖到/usr/local/src/nginx_check.sh下，与上图路径一致。

5.开启两个虚拟机的nginx和keeplived

命令：

    ./nginx

    systemctl start keepalived.service

6.测试访问虚拟的端口号。

7.让master宕机

    ./nginx -s stop

    systemctl stop keepalived.service

8.再次访问，与上一次对比。
