usr/bin/mysqladmin: refresh failed; error: 'Unk_MySQL

May 31, 2016 am 08:49 AM

debian wheezy 升级后, 因为授权错误, 导致密码给修改, 在debian的mysql safe下也无法进入.  

我在/etc/mysql/my.cnf 里面已经修改了bind-address 为局域网ip

进而执行了

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;

然后重载授权表:

FLUSH PRIVILEGES;

然后重启后, 虽然可以远程链接, 但是debian 本身报了一个mysql的error.

/etc/cron.daily/logrotate:

/usr/bin/mysqladmin: refresh failed; error: 'Unknown error'

error: error running shared postrotate script for '/var/log/mysql.log /var/log/mysql/mysql.log /var/log/mysql/mysql-slow.log '

run-parts: /etc/cron.daily/logrotate exited with return code 1

Saved 4 messages in /home/tom/mbox

这个问题的产生是因为第一次mysql服务启动的时候mysql_safe的error.log日志文件是被root创建的, mysqladmin 调用cron的日志分割清除这个日志文件没有权限导致的.

这个bug已经在新点儿的debian sid里面修复了, 但是stable版本还没有接到这个fix.

解决办法:

重新配置下mysql的error_log , 在my.cnf里面. 并且让你的mysql对这个文件有权限.

-rw-r-----1 rootadm517639 [2014-07-019:26] mysql_error.log

Copy after login

修改root为mysql 就可以了

chown mysql /var/log/mysql/mysql_error.log
