Install Redis on CentOS 6.4
source：http://thoughts.z-dev.org/2013/05/27/install-redis-on-centos-6-4/
We’re provisioning production machines today!
This means that I’m finding a lot of things that I did previously to make my life easier. We use Redis primarily to temporarily cache data retrieved from Riak and this dramatically reduces that amount of stress on our Riak cluster.
Unfortunately, Redis doesn’t (by default) have its own package in yum. 
The Hard Way
Like most freely distributed software, the process is pretty much the same: download, extract and compile.
This is what that looks like:
wget http://redis.googlecode.com/files/redis-2.6.13.tar.gz tar xzf redis-2.6.13.tar.gz cd redis-2.6.13 make
Unfortunately that keeps the binaries in /usr/local/bin and doesn’t include a init script (boo).
The Easy Way
Fortunately, there’s the REMI repository which packages common programs and distributes them. Let’s see what it looks like with that
wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm wget http://rpms.famillecollet.com/enterprise/remi-release-6.rpm rpm -Uvh remi-release-6*.rpm epel-release-6*.rpm yum install redis -y
This means that we don’t have to manually update Redis and that we can use the included init script to start, stop, and restart the service.
Just thought I’d throw that out there since this is a relatively annoying issue that’s pretty easy to solve.
