Mariadb 5.5.30 用  percona 5.5.30 的mysql系统库启动时会报错

[ERROR] Incorrect definition of table mysql.event: expected column ‘sql_mode’ at position 14 to have type set …… [ERROR] mysqld: Table ‘./mysql/tables_priv’ is marked as crashed and should be repaired [Warning] Checking table: ‘./mysql/tables_priv’ [ERROR] mysql.tables_priv: 1 client is using or hasn’t closed the table properly mysql.proc ….. 

Mariadb和percona的mysql.event此表结构有点不同

导致event无法使用， 在咨询P.linux兄后，解决办法如下

装一个纯净的mariadb，

然后从percona导出mysql库

mysqldump  -B mysql  –opt  –triggers=true  –events  -u root -p > mmmmmysql.sql

注释掉mysql.event, mysql.proc 表的建表语句(留下insert)，然后手工导mmmmmysql.sql 进Mariadb 5.5.30

再启动Mariadb就没报错了 ，能正常运行！
