Example of re-mount VAR partition in Linux

We sometimes find that the Var partition uses Du and DF to see that the usage is inconsistent, typically because some files are deleted, but the file is also occupied by the program, causing the space to not be released. Sometimes, you know which program is occupied, directly after restarting the program, you can release directly, sometimes you need to uninstall the Var partition to completely release the space.
