远程服务器Linux错误 ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES）

vim /etc/my.cnf

在[mysqld]后面任意一行添加“skip-grant-tables”

service mysqld restart 

mysql

flush privileges;

grant all privileges on *.* to root@'%' identified by '123456' with grant option;

quit;

service mysqld restart 

or

mysql> use mysql;
mysql> update user set password=password("你的新密码") where user="root";
mysql> flush privileges;
mysql> quit

最后

去掉刚才添加的内容

skip-grant-tables
