MySQL异机迁移后,启动数据库报错

# /data/mysql_57_software/bin/mysqld_safe --defaults-file=/etc/my3319.cnf --user=mysql &# tail -20 /var/log/mysqld3319.log2019-01-02T07:11:01.716793Z 0 [ERROR] InnoDB: The innodb_system data file './ibdata1' is of a different size 17152 pages (rounded down to MB) than the 64000 pages specified in the .cnf file!2019-01-02T07:11:01.716832Z 0 [ERROR] InnoDB: Plugin initialization aborted with error Generic error2019-01-02T07:11:02.317322Z 0 [ERROR] Plugin 'InnoDB' init function returned error.2019-01-02T07:11:02.317347Z 0 [ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed.2019-01-02T07:11:02.317353Z 0 [ERROR] Failed to initialize plugins.2019-01-02T07:11:02.317361Z 0 [ERROR] Aborting


报错原因:

参数文件中的系统表空间大于实际的系统表空间大小,导致启动报错。

# du -sh /data/mysql_3319/ibdata1268M    /data/mysql_3319/ibdata1# cat /etc/my3319.cnf# innodbinnodb_data_file_path=ibdata1:1000M;ibdata2:1000M:autoextend


解决办法:

将参数文件中系统表空间的大小改为小于实际系统表空间大小的值。

# innodbinnodb_data_file_path=ibdata1:256M;ibdata2:256M:autoextend
