Redis Master-Slave configuration

First, the preparatory work

Two machine operating systems are centos6.7, the IP card eth0 are:

Master 192.168.1.180
Slave 192.168.1.181

Second, the basic operation (all the following steps are to operate on two machines)

1, set hostname, respectively, master and slave

Lord set hostname

# hostname master//temporary effective

Or

# Vim/etc/sysconfig/network//Permanent effect
Hostname=Master

Set hostname from above

# hostname Slave//Temporary entry into force

Or

# Vim/etc/sysconfig/network//Permanent effect
Hostname=Slave

2. Turn off the firewall

The Lord and the slave are emptying iptables

The master and slave both turn off SELinux

# Setenforce 0

Redis Installation Steps

3. Configuration

Since I did not set the password for Redis prior to configuring the master, I can directly configure the connection without giving the master configuration. (If you want to set up is also possible)

Master configuration

From configuration: Also add the master's password on the slave

See if it's successful

In the main

It's already there. Description we have successfully configured.
