Redis Standalone Multi-entity installation and master-slave configuration

The previous article explained the Redis installation on CentOS.

Now let's take a look at the installation of Redis standalone Multi-instance

First turn off Redis

Based on the configuration file location of the previous Redis installation

First we copy the Redis configuration file

Cp/etc/redis/6379.conf/etc/redis/6380.conf

Then modify the information in the 6380.conf configuration file:

Port ports changed to 6380

Data storage directory dir change to/var/lib/redis/6380 and create the corresponding directory

Log storage location logfile change to/var/log/redis_6380.log

PID file name changed to/var/run/redis_6380.pid

Then we copy/etc/init.d/redis_6379, modify the redis_6380 script file, change the original 6379 to 6380

cp/etc/init.d/redis_6390/etc/init.d/redis_6380

At this point, single-machine multi-instance installation is complete

Next we can do the master-slave configuration

To modify the/etc/redis/6380.conf file:

Find slaveof, modify the configuration as follows, if it is configured on this machine, you can also write IP 127.0.0.1, when the primary server has a password do not forget to add a password in Masterauth

After the configuration is complete, restart from the database

Service redis_6380 Restart

Then view the master and slave configuration information

Primary server information:

From server information:

This is the master-slave configuration completed

Test it:
