This guide is one section of a larger guide to installing a cent 6.x server in virtual box for development purposes with different applications. The top level guide with links to all of the sections is here: https://gist.github.com/ryanguill/5149058 Some instructions in this guide may assume a configuration from other parts of the guide.
#Install Redis
Instructions taken loosely from here: http://www.ebrueggeman.com/blog/install-redis-centos-56
See also these instructions: http://library.linode.com/databases/redis/centos-5 ... might be good to create a special user for redis to run as like these instructions talk about.
# su -
# yum install make gcc wget telnet
# wget http://download.redis.io/releases/redis-2.8.9.tar.gz
# tar -xvf redis-2.8.9.tar.gz
# cd redis-2.8.9
# make && make install
We're going to change the default redis.conf file to daemonize it, change the location of the database, change the log notices to a production acceptable level, and change the logfile location.
# mkdir /etc/redis /var/lib/redis
# sed -e "s/^daemonize no$/daemonize yes/" -e "s/^dir \.\//dir \/var\/lib\/redis\//" -e "s/^loglevel debug$/loglevel notice/" -e "s/^logfile stdout$/logfile \/var\/log\/redis.log/" redis.conf > /etc/redis/redis.conf
To make management easy, we're going to use an init script that I found here on github. The install location on this script doesn't match where the /usr/local/bin/redis-server location we're using, so I'm using sed to update it.
# wget https://gist.githubusercontent.com/paulrosania/257849/raw/9f1e627e0b7dbe68882fa2b7bdb1b2b263522004/redis-server
# sed -i "s/usr\/local\/sbin\/redis/usr\/local\/bin\/redis/" redis-server
# chmod u+x redis-server
# mv redis-server /etc/init.d
# /sbin/chkconfig --add redis-server
# /sbin/chkconfig --level 345 redis-server on
# /sbin/service redis-server start
By now it should be running. Test it out
# redis-cli
# set foo bar
# get foo
We need to edit the redis.conf to tell it to write the data to the /data partition
Create the directory for redis data
# mkdir /data/redis
# sudo chmod 777 /data/redis
# sudo chown user:user /data/redis
If you want to make sure that Redis writes synchronously to disk (because you care about every write that happens) - change the config to be appendonly yes
# sudo vi /etc/redis/redis.conf
Look for the line that says
dir /var/lib/redis/
Change it to say:
dir /data/redis/
Then, if you want to make sure that Redis writes synchronously to disk (because you care about every write that happens) - change the config to be appendonly yes
Find this line and change no to yes
appendonly no
Restart the service
# sudo service redis-server restart
