MySQL 经常崩溃

Question

MySQL 服务器再次崩溃，我不知道如何解决此问题：我将 mysql 用于 wordpress。

崩溃时的系统状态：

● mysql.service - MySQL Community Server
   Loaded: loaded (/lib/systemd/system/mysql.service; enabled; vendor preset: enabled)
   Active: failed (Result: start-limit-hit) since Tue 2022-09-27 06:48:56 UTC; 35min ago
  Process: 5801 ExecStartPost=/usr/share/mysql/mysql-systemd-start post (code=exited, status=0/SUCCESS)
  Process: 5800 ExecStart=/usr/sbin/mysqld (code=killed, signal=KILL)
  Process: 5792 ExecStartPre=/usr/share/mysql/mysql-systemd-start pre (code=exited, status=0/SUCCESS)
Main PID: 5800 (code=killed, signal=KILL)

启动服务器后：

● mysql.service - MySQL Community Server
   Loaded: loaded (/lib/systemd/system/mysql.service; enabled; vendor preset: enabled)
   Active: active (running) since Tue 2022-09-27 07:31:15 UTC; 3min 12s ago
