opensuse – 无法启动mysql服务

试图启动我的@L_502_0@服务.

/etc/init.d/MysqL start

收益：

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

进一步：

systemctl status MysqL.service

收益：

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

任何想法我怎么能找出发生了什么？

解决方法:

/ var / lib / MysqL / aria_log_control文件由另一个进程打开,因此MysqLd无法启动.

检查当前打开文件的人/用户：

lsof `/var/lib/MysqL/aria_log_control`

它应该列出打开它的进程.

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

如果该进程肯定不应该运行,那么关闭它：

sudo kill -SIGTERM <PID>

如果失败：

sudo kill -SIGKILL <PID>

或重启.
