    CentOS7启动MYSQL报错
    27
    0

    [root@localhost init.d]# service mysql start
    Redirecting to /bin/systemctl start mysql.service
    Job for mysqld.service failed because a timeout was exceeded. See "systemctl status mysqld.service" and "journalctl -xe" for details.

    在日志中发现错误:
    2017-12-08 14:37:52 32407 [ERROR] InnoDB: ./ibdata1 can't be opened in read-write mode
    2017-12-08 14:37:52 32407 [ERROR] InnoDB: The system tablespace must be writable!

    2017-12-08 14:37:52 32407 [Note] Binlog end

    网上找到的解决方法删除DATA文件夹下的两个文件重启mysql并不管用
