Redis Server

The redis server is used by Nextcloud to lock files much faster than using the database.

Installation

• Open YaST
• Open Software Management
• Search for redis
• Select package redis for installation

NOTE: You may see 2 packages - redis and redis7. redis7 is an out of date version of redis - install the redis package.

• Ensure the php8-redis package is also installed.
• Accept the installation and allow the package to install.

Configuration

• Open /etc/redis/default.conf.example file with nano
• We will be using Unix sockets so amend the following:
  • port 6379 -> port 0
  • # unixsocket /run/redis.sock -> unixsocket /var/run/redis/redis.sock
  • # unixsocketperm 700 -> unixsocketperm 770

NOTE: Be sure to # uncomment the last two lines.

• Save the file as redis.conf

Starting and testing the server

• Run sudo service redis@redis start
• Run redis-cli -s /var/run/redis/redis.sock
• Check by typing ping. You should receive the response PONG
• Exit by typing exit

NOTE: The service name changes depending on the .conf file name - e.g. if you save d the configuration as default.conf, you would run service redis@default start.

Allow web server access

• Start YaST
• Go to 'Security and Users'
• Open 'User and Group Management'
• Go to the 'Groups' tab
• Select 'Set Filter' then select 'System Groups'
• From the list, find the redis group
• Select 'Edit'
• In the 'Group Members' box, find wwwrun and select it.
• Once done, accept and close YaST.
