安装wdcp时显示mysql链接错误,wdcp安装好后root账号无法登陆,错误提示:mysqladmin: connect to server at 'localhost' failed

error: 'Access denied for user 'root'@'localhost' (using password: YES)'

解决办法:

修改my.cnf文件在[mysqld]下添加skip-grant-tables重启数据库(sudo service mysqld restart)后修改root密码

update mysql.user set password=password(‘新密码’) where user=’root’;

flush privileges;

quit;

退出后把my.cnf修改回来然后进行重启,问题解决.
