Install Redis cache
Download Redis from http://redis.io/download:
Extract it and compile with:
tar -xzvf redis-3.0.0.tar.gz cd redis-3.0.0 make
Create data directory for redis
This directory will work as data and working directory for your Redis instance:
mkdir -p /var/redis/6379
Create configuration file for redis
Create a directory where to store your Redis config files:
Copy the template configuration file you'll find in the root directory of the Redis distribution into
/etc/redis/ using the port number as name, for instance:
cp redis.conf /etc/redis/6379.conf
Edit this file, making sure to perform the following changes:
- Set daemonize to
yes(by default it is set to no).
- Set the pidfile to
/var/run/redis_6379.pid(modify the port if needed).
- Change the port accordingly. In our example it is not needed as the default port is already
- Set your preferred loglevel.
- Set the logfile to
- Set the dir to
/var/redis/6379(very important step!)
- Uncomment line
# bind 127.0.0.1(very important step for security reasons! With such settings redis will be accessible only from localhost. It will reject connections from outside network.)
Create init script for redis
Copy the init script that you'll find in the Redis distribution under the
/etc/init.d. We suggest calling it with the name of the port where you are running this instance of Redis. For example:
cp utils/redis_init_script /etc/init.d/redis_6379
Edit the init script.
Add the following lines at the top of init script (below line #!/bin/sh):
#!/bin/sh # # Simple Redis init.d script conceived to work on Linux systems # as it does use of the /proc filesystem. # # chkconfig: - 85 15 # description: Redis is a persistent key-value database # processname: redis
Make sure to modify REDIS_PORT accordingly to the port you are using. Both the pid file path and the configuration file name depend on the port number.
Finally add the new Redis init script to all the default runlevels using the following command:
chkconfig --add redis_6379 chkconfig redis_6379 on
You are done! Now you can try running your instance with:
Verify Redis installation
Make sure that everything is working as expected:
- Try pinging your instance with
- Do a test save with
redis-cli saveand check that the dump file is correctly stored into /var/redis/6379/ (you should find a file called dump.rdb).
- Check that your Redis instance is correctly logging in the log file /var/log/redis_6379.log.
- If it's a new machine where you can try it without problems make sure that after a reboot everything is still working.
