Install Redis on Centos 6.5

1. First, make sure the following repos, EPEL and REMI, are installed:

   sudo rpm -Uvh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
   sudo rpm -Uvh http://rpms.remirepo.net/enterprise/remi-release-6.rpm
   

2. Check the version of Redis in REMI repo: (As of June 2015, the version is 2.8.13)

   yum --enablerepo=remi info redis
   

3. Then install related dependency (jemalloc) from EPEL repo:

   sudo yum --enablerepo=epel install jemalloc
   

4. Before installation, you should stop the old Redis daemon:

   sudo service redis stop
   

5. Then install the newer version of Redis:

   sudo yum --enablerepo=remi install redis
   

6. Edit Redis configuration file if needed:

   sudo vi /etc/redis.conf
   

7. Restart Redis daemon, and make it auto-start on reboot:

   sudo service redis start
   sudo chkconfig redis on
   

8. Finally, check the version of currently installed Redis:

   redis-cli info | grep redis_version
