mysql数据库设置远程连接权限,执行grant all privileges on *.* to 'root'@'%' identified by '密码' with grant optio报错
ERROR1558 (HY000): Column count ofmysql.user is wrong. Expected 43, found 42. Created with MySQL 50556, now running 50639. Please use mysql_upgrade to fix this error.
解决办法:
使用命令:mysql_upgrade -u[username] -p[password]
就可以解决。
使用mysql_upgrade
对数据库的数据表结构等升级时,数据库引擎MyISAM 会做检查、修复的动作,InnoDB 执行 mysql_upgrade 没有作用。
查找MySQL的安装目录找到mysql_upgrade :
- whereismysql_upgrade
- cd /usr/bin/
- ./mysql_upgrade -uroot -p123 (123为密码)
然后进入到mysql再执行权限修改即可:grant all privileges on *.* to 'root'@'%' identified by 'root4xml004a' with grant option;
如:
mysql中远程连接权限语句grant all privileges on *.* to ‘root‘@‘%‘ identified by ‘123456‘ with grant optio报错
grant all privileges on *.* to ‘root‘@‘%‘ identified by ‘123456‘ with grant optio
原因: mysql的版本问题,这条语句适用于MySQL8.0之前
解决: mysql8.0及以上版本需要使用以下语句:
create user root@'%' identified by '123456'; grant all privileges on *.* to root@'%' with grant option;
