1. Software Installation
Here we assume the master server IP is 192.168.1.100, and the slave server is 192.168.1.200
yum -y install redis
Enable on startup:
chkconfig –add redischkconfig redis on
Add firewall rule:
/sbin/iptables -I INPUT -p tcp –dport 6379 -j ACCEPT/etc/rc.d/init.d/iptables saveservice iptables restart

2. Master Server Configuration:
vi /etc/redis.conf
Add authentication password at the end:
requirepass Redis197
Where Redis197 can be changed to anything you prefer
Start the server:
service redis start
3. Slave Server Configuration:
vi /etc/redis.conf
Add master server information at the end:
slaveof 192.168.1.100 6379masterauth Redis197requirepass Redis197
Start the server:
service redis start
4. Testing:
Execute on the master server:
redis-cli -h 192.168.1.100 -a Redis197 set test 123456
Execute on the slave server:
redis-cli -h 192.168.1.200 get test
If successful, it will return:
“123456”
To add multiple slave servers, simply repeat the slave server configuration steps above.
