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/ibdata1
268M /data/mysql_3319/ibdata1
# cat /etc/my3319.cnf
# innodb
innodb_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。
# innodb
innodb_data_file_path=ibdata1:256M;ibdata2:256M:autoextend
--结束END--
