Keepalived高可用集群实践

(1)实践的硬件环境准备

  准备4台物理服务器或者4台VM虚拟机,其中两台用来做Keepalived服务器,两台做web测试站点

HOSTNAME I  P 解    释
lb01  10.0.0.7 Keepalived主服务器(Nginx主负载均衡器)
lb02 10.0.0.8 Keepalived备服务器(Nginx备负载均衡器)
web01 10.0.0.9 web01服务器
web02 10.0.0.10 web02服务器

(2)开始安装Keepalived软件

  #yum install Keepalived -y

  #rpm -qa Keepalived

  (注意:上面安装过程需要在lb01和lb02两台服务器同时安装)

(3)启动Keepalived服务并检查

  启动及检查Keepalived服务命令如下:

    #/ect/init.d/Keepalived start

    #ps -ef | grep Keep | grep -v grep
