问题
在执行命令重启数据库服务的时候，出现以下错误：
[ERROR]InnoDB:Unable to lock /data/ibdata1 error:11
[Note]InnoDB:Check that you do not already have another mysqld porcess using the same InnoDB data or log files.
[ERROR]InnoDB: Cannot open datafile '/data/ibdata1'
解决
- 注意日志中的以下提示：
[Note]InnoDB:Check that you do not already have another mysqld porcess using the same InnoDB data or log files.
- 检查进程
ps -ef | grep mysql后发现有个数据库的进程在运行 kill -9 进程id杀掉进程，后重启成功
