  • 手动替换mysql 数据库文件导致mysql无法启动

    The server quit without updating PID file (/usr/local/mysql/data/mysql.pid

    这个错误几乎包揽了mysql的所有启动报错;

    查一下sql 错误日志

    InnoDB: To fix the problem and start mysqld:
    InnoDB: 1) If there is a permission problem in the file and mysqld cannot
    InnoDB: open the file, you should modify the permissions.
    InnoDB: 2) If the table is not needed, or you can restore it from a backup,
    InnoDB: then you can remove the .ibd file, and InnoDB will do a normal
    InnoDB: crash recovery and ignore that table.
    InnoDB: 3) If the file system or the disk is broken, and you cannot remove
    InnoDB: the .ibd file, you can set innodb_force_recovery > 0 in my.cnf
    InnoDB: and force InnoDB to continue crash recovery here.
    160721 12:14:43 mysqld_safe mysqld from pid file /usr/local/mysql/data/mysql.pid ended

    首先InnoDB;

    在者

    If the table is not needed, or you can restore it from a backup,
      then you can remove the .ibd file, and InnoDB will do a normal
        crash recovery and ignore that table.

    由于我用一个innodb表引擎的数据库 覆盖了另外一个无用的数据库文件;

    rm -rf 错误的table
