伙计们，我在使用 MYSQL 时遇到了一些问题，我尝试了解决方案但仍然没有找到答案，所以基本上问题是当我总是尝试启动或重新启动服务时，输出给出了这个答案：
"Job for mysql.service failed because the control process exited with error code.
See "systemctl status mysql.service" and "journalctl -xe" for details."
当我输入“systemctl status mysql.service”和“journalctl -xe”时，这是输出：
mysql.service - MySQL Community Server
