mysql编译安装完启动时候报错

Posted 2020-09-03

[[email protected] mysql]# /etc/init.d/mysqld start

Starting MySQL. ERROR! The server quit without updating PID file (/tmp/mysql.pid).

[[email protected] mysql]# tail -f data/host2.err 

InnoDB: Error: log file ./ib_logfile0 is of different size 0 4194304 bytes

InnoDB: than specified in the .cnf file 0 5242880 bytes!

170310 17:06:48 mysqld_safe mysqld from pid file /application/mysql/data/host2.pid ended

说函数误差

解决方法：

把data下面的ib_logfil文件删除即可

[[email protected] mysql]# rm -f data/ib_logfile0 

[[email protected] mysql]# rm -f data/ib_logfile1

[[email protected] mysql]# rm -f data/ib_logfil2
