mysql开启远程访问权限错误

<Category: mysql> Comments Off on mysql开启远程访问权限错误

mysql需要开放远程访问端口,结果。。
mysql> update user set host =’%’ where user =’root’;
ERROR 1062 (23000): Duplicate entry ‘%-root’ for key ‘PRIMARY’

root用户好几个,有几个没有密码
mysql> update user set password = PASSWORD(‘xxx’) where user=’root’
-> ;
删除最后一个root用户:
localhost root

然后确保有一个%就可以了。
