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