This environment is based on centos7 deployment, and the basic architecture diagram:

Client ip: 192.168.1.101

Lvs1 ip: 192.168.1.173

Lvs2 ip: 192.168.1.110

Web1: 192.168.1.114

Web2: 192.168.1.119

VIP: 192.168.1.10

Deployment process:

Lvs1:

# yum install ipvsadm

# ipvsadm # check whether the output installation is successful

# yum install keepalived

# vim / etc/keepalived/keepalived.conf
