Redis server on openSUSE

Installation

sudo zypper in redis

Configuration

Copy default config file

sudo cp -a /etc/redis/default.conf.example /etc/redis/instancename.conf

We use the cp -a here, so that our permissions are preserved.
In case you copied the file without the -a:

sudo chown root:redis  /etc/redis/instancename.conf
sudo chmod u=rw,g=r,o= /etc/redis/instancename.conf

Add user to redis group with YaST, logout and login.

Minimal config

Change at least pidfile, logfile and dir setting the pid file has to match your config filename without the .conf

pidfile /run/redis/instancename.pid
logfile /var/log/redis/instancename.log
dir /var/lib/redis/instancename/

If you want to run more than one instance you also have to change the socket path and/or the ip:port combination.
e.g. /run/redis/instancename.sock
Also make sure if you copy configurations from somewhere, that daemonize should be set to no.

Create the database dir

sudo install -d -o redis -g redis -m 0750 /var/lib/redis/instancename/
sudo systemctl start redis@instancename
sudo systemctl enable redis@instancename

To stop/restart all instances at the same time use:

sudo systemctl restart redis.target
sudo systemctl stop redis.target

Default config

bind 127.0.0.1 -::1
protected-mode yes
port 6379

Use Unix socket

Add this in conf file:

unixsocket /var/run/redis/instancename.sock
unixsocketperm 775

Integration with apache when using unix domain sockets

If you plan to use redis in combination with apache, then you should add redis to apache group and set unixsocketperm 770:

sudo usermod -a -G redis wwwrun
sudo systemctl restart apache2

apache is now able to connect to the redis socket.
