Mysql installed in the LNMP one-click package enables Mysql logs by default. If the website reads and writes data to the database frequently, it may generate a large number of logs and occupy disk space, it is also possible that the idle space of the VPS hard disk is fully occupied and the database cannot be enabled.
The path for this tutorial is applicable to the one-click installation package environment of LNMP. For other environments, perform the operations as needed.
