How to Change RAM Limits on OpenVZ?
OpenVZ is a popular virtualization software that provides virtual private servers (VPS) based on containers. One of the main parameters that can be changed to optimize the performance of a VPS is the Random Access Memory (RAM) limit.
In this article, we’ll talk about how to change RAM limits on OpenVZ using the command line. This process is quite simple and can be done even by a beginner in the field of server administration.
Step 1: Checking Current RAM Limits
Before changing RAM limits, it is important to know the current settings. To do this, run the following command:
cat /proc/user_beancounters
In the command output, you will see information about available RAM and limits set for your container.
Step 2: Changing RAM Limits
To change the RAM limits on OpenVZ, use the following command:
sudo vzctl set --vmguarpages : --save
Replace <container_number> with the real number of your container, <new_RAM_limit> with the new RAM limit in pages, and <new_SWAP_limit> with the new swap limit.
After executing the command, restart the container to apply the changes:
sudo vzctl restart
Step 3: Verifying Changes
To check your changes, run the command:
cat /proc/user_beancounters
Now you will see that the RAM limits have been successfully changed on your OpenVZ container.
Changing RAM limits on OpenVZ allows you to optimize the performance of your virtual private server and increase its productivity. Follow our instructions and configure your VPS perfectly for your needs!
