解决警告:数据库错误Column count of mysql.proc is wrong.

事实上,如果你使用phpMyAdmin,你找不到错误问题出在哪里?

  • 问题就因为你已升级MariaDB或MySQL数据库版本。
  • 升级MariaDB或MySQL数据库版本后,数据结构未使用mysql_upgrade命令完成升级更新。
  • 之后,操作MySQL数据库过程中,可能将显示错误消息.

WordPress插件在自动备份过程期间,发生以下错误 ▼

警告: 数据库错误 Column count of mysql.proc is wrong. Expected 21, found 20. Created with MariaDB 50560, now running 100406. Please use mysql_upgrade to fix this error 查询 SHOW FUNCTION STATUS

  • mysql.proc 这是5.1中的系统表,它记录有关存储过程或函数的信息。

如何解决警告:数据库错误 Column count of mysql.proc is wrong?

以下是陈沩亮记录的解决方案。

第 1 步:保险做法是先dump或冷备份:

mysqldump -uroot -p123456 --quick --master-data=1 --all-databases --flush-logs --lock-tables >
  • 请将以上的“123456”,改成你的MySQL的root密码。

第 2 步:使用以下mysql_upgrade 命令来解决

mysql_upgrade -u root --datadir=/var/lib/mysql/ --basedir=/ --password=123456

以下是SSH示范操作过程 ▼

[root@db lib]# mysql_upgrade -u root -p123456 -hdb --datadir=/var/lib/mysql/ --basedir=/
