mariadb启动报错：[ERROR] InnoDB: The Auto-extending innodb_system data file。。。

报错内容：[ERROR] InnoDB: The Auto-extending innodb_system data file ‘/data/mysql-33061/data/ibdata1’ is of a different size 768 pages than specified in the .cnf file: initial 131072 pages, max 0 (relevant if non-zero) pages!

问题分析：之前启动的mysql存在旧的文件，导致冲突

问题解决：删除冲突文件/data/mysql-33061/data/ibdata1即可
