無法啟動mysql服務

試圖啟動我的mysql服務。

/etc/init.d/mysql start

返回：

Job failed. See system logs and 'systemctl status' for details.

更遠：

systemctl status mysql.service

返回：

mysql.service - LSB: Start the MySQL database server
     Loaded: loaded (/etc/init.d/mysql)
     Active: failed since Mon, 04 Aug 2014 16:20:43 -0400; 38s ago
    Process: 14148 ExecStop=/etc/init.d/mysql stop (code=exited, status=0/SUCCESS)
    Process: 16457 ExecStart=/etc/init.d/mysql start (code=exited, status=1/FAILURE)
     CGroup: name=systemd:/system/mysql.service

有什麼想法可以讓我知道發生了什麼嗎？

最新條目/var/log/mysql/mysqld.log：

該/var/lib/mysql/aria_log_control文件已被另一個程序打開，因此mysqld無法啟動。

檢查誰/什麼目前打開了文件：

lsof `/var/lib/mysql/aria_log_control`

它應該列出打開它的程序。

COMMAND  PID  USER   FD   TYPE DEVICE SIZE/OFF   NODE NAME
mysqld  1506 mysql   10uW  REG  253,1       52 263948 /var/lib/mysql/aria_log_control

如果該過程絕對不應該執行，則使用以下命令將其關閉：

sudo kill -SIGTERM <PID>

如果失敗：

sudo kill -SIGKILL <PID>

或者重啟。
