Installing Redis, Memcached on CentOS 5.7

Redis:

Install

sudo su
yum install make gcc wget telnet
wget -c http://redis.googlecode.com/files/redis-2.6.7.tar.gz
tar zxfv redis-2.6.7.tar.gz
cd redis-2.6.7
make && make install

Config

mkdir -p /etc/redis /mnt/var/lib/redis
sed -e "s/^daemonize no$/daemonize yes/" -e "s/^dir \.\//dir \/mnt\/var\/lib\/redis\//" -e "s/^loglevel debug$/loglevel notice/" -e "s/^logfile stdout$/logfile \/mnt\/var\/log\/redis.log/" redis.conf > /etc/redis/redis.conf

Manage use init script redis (refer to: a script to start and stop redis daemon)
