1558 - Column count of mysql.proc is wrong. Expected 20, found 16. Created with MySQL 50018, now running 50146. Please use mysql_upgrade to fix this error.

今天58lianmeng服务器上出现了这个不起眼的错误。 其实这个错误如果用phpmyadmin的话发现不了、
错误来源，是由于你曾经升级过数据库。
升级完后未使用mysql_upgrade升级数据结构造成的。
用Navicat For MySQL会有此错误提示。
记录一下解决方法。 mysql.proc
这个是5.1里面的系统表来的,用来记录存储过程或函数的信息. 你的数据库肯定作过升级或用不同的版本进行备份迁移恢复. 解决办法:
使用命令：mysql_upgrade 就可以解决 mysql_upgrade -u root -p123456 --datadir=D:\Database --basedir=D:\Mysql
MySQL utility for upgrading databases to new MySQL versions.
问题 重新开机后, 查看当机前发生的事情, 都是出现下述讯息:

解法
看来像是 MyISAM 的 Table 出问题, 但是, 检查起来都没任何异常, 先假设是升级 MySQL 造成的问题, 所以手动执行 mysql_upgrade 来完成升级动作. 注: 下述指令于 MySQL upgrade 后, 都可以手动执行. (InnoDB 执行 mysql_upgrade 没有作用, MyISAM 会做检查、修复的动作)
$ sudo mysql_upgrade -u root -p # 若出现下述讯息, 则加上 --force
This installation of MySQL is already upgraded to 5.1.49, use --force if you still need to run mysql_upgrade
$ sudo mysql_upgrade --force -u root -p

暂时做个纪录, 希望别再发生问题.
