(1) Prepare the hardware environment in practice

Prepare four physical servers or four vmvms, two of which are used for Keepalived servers and two for web testing sites.

HOSTNAME	I P	Release
Lb01	10.0.0.7	Keepalived master server (Nginx master Load balancer)
Lb02	10.0.0.8	Keepalived Backup Server (Nginx Backup Server Load balancer)
Web01	10.0.0.9	Web01 Server
Web02	10.0.0.10	Web02 Server

(2) start to install the Keepalived software.

# Yum install Keepalived-y

# Rpm-qa Keepalived

(Note: The above installation process must be installed on both lb01 and lb02 servers)

(3) Start the Keepalived service and check

Run the following command to start and check the Keepalived service:

#/Ect/init. d/Keepalived start

# Ps-ef | grep Keep | grep-v grep
