我有一个 EC2 实例,其中 Mysql 服务器工作正常。我由此创建了一个 AMI,并从此 AMI 启动了一个新实例。现在 Mysql 服务器根本无法在这个新的 AMI 上启动。
下面是o/p:
ubuntu@ip-172-31-66-160:~$ sudo service mysql status

Job for mysql.service failed because the control process exited with error code. See "systemctl status mysql.service" and "journalctl -xe" for details.
我尝试了一切,但无法开始。
我遇到并遵循的最接近的线程没有任何运气:

- https://support.plesk.com/hc/en-us/articles/360004185293-Unable-to-start-MySQL-on-Ubuntu-AVC-apparmor-DENIED-operation-open-
请帮忙,我对此一无所知。
