Remove Redis from a DirectAdmin Server in 6 Steps

Redis is commonly used for caching and real-time data processing. However, if we no longer use Redis on the DirectAdmin server, it’s a good idea to remove it cleanly to free up system resources and eliminate potential security risks.

This blog takes us through removing Redis from a DirectAdmin-managed server step-by-step.

Step 1: Stop the Redis Service

Before beginning the uninstallation process, ensure the Redis service is not running.

Here is the command to stop Redis:

sudo systemctl stop redisCopy Code

If Redis was started manually or via a custom script, we must stop it.

Step 2: Disable Redis from Starting at Boot

To prevent Redis from automatically starting during future reboots, we can disable it with this command:

sudo systemctl disable redisCopy Code

Step 3: Uninstall Redis

The removal method depends on how Redis was initially installed.

• If installed via APT (Debian/Ubuntu):

  sudo apt-get remove --purge redis-serverCopy Code
• If installed via YUM (CentOS/RHEL):

  sudo yum remove redisCopy Code
• If installed from source, we have to delete the binaries and associated directories manually:

  
  sudo rm /usr/local/bin/redis*
  sudo rm -rf /etc/redis/
  sudo rm -rf /var/lib/redis/
  Copy Code

Like removing Redis, keeping your server lightweight often involves managing software installations. If you’re planning more significant changes, check out our DirectAdmin to Plesk migration guide.

Step 4: Remove Redis Configuration Files

Even after uninstalling Redis, some configuration files may remain. To clean up, run:

sudo rm -rf /etc/redis/Copy Code

Also, double-check if any data files were stored in custom directories and remove those manually.

Step 5: Verify Redis Removal

To confirm Redis has been fully removed, check the following:

• Check if Redis is still running:

  ps aux | grep redisCopy Code
• Check if Redis binaries still exist:

  which redis-serverCopy Code

If everything has been removed properly, these commands should return no results.

Step 6: Reboot the Server

To ensure all services are refreshed and changes take effect, we need to reboot the server:

sudo rebootCopy Code

Additional Tips

• If Redis is storing critical data, back it up before removal.
• Ensure no other services on the server depend on Redis. Removing it could break those services.
• If Redis is used for caching, consider switching to other caching tools like Memcached or application-level caching strategies.
