操作系统： Ubuntu 16.04.1 LTS xenial
我在AWS上的服务器上安装了MySQL并且工作正常，但在我们开始在网站上获得大量流量后，它开始频繁失败。要修复它，我通常会重新启动服务或服务器，但只能运行几分钟/小时，然后再次失败。现在，即使重新启动服务器，MySQL也不会再次启动。
正在运行sudo systemctl start mysql我收到此消息
mysql.service的作业失败，因为控制进程退出并显示错误代码。请参阅＆＃34; systemctl status mysql.service＆＃34;和＆＃34; journalctl -xe＆＃34;详情。
这是/var/log/mysql/error.log
