How to Safely Clear RAM Cache aaPanel

ianasystems

Hello,

I’m running aaPanel on a VPS (Ubuntu 22.04) and I want to manually clear RAM cache, similar to how we use RAMMap on Windows to clear the standby list or empty working sets.

Here is my current memory status:

root@server:~# free -h
total used free shared buff/cache available
Mem: 11Gi 2.6Gi 8.3Gi 104Mi 743Mi 8.7Gi
Swap: 0B 0B 0B
root@server:~#

Linux automatically uses RAM for caching, which is normal, but sometimes I want to manually reset/clear the cache to free up RAM instantly.

Thanks.

Hello,
It is not recommended that you release it manually,
sudo sync && sudo sysctl -w vm.drop_caches=1

Thank you, it worked! The RAM clear is working fine.

Now I want to ask how to clear disk space. I have a button inside the panel dashboard called “Disk space: Clear up.” What happens if I click on it? Is it safe to clear disk space using this button?

This is to install a Disk analysis plug-in. Use the Disk analysis plug-in to search for server space usage.
