安装Mysql后在终端输入mysql, mysql
成功启动，退出，再输入mysqladmin -u root password XXXXX， 出现错误：mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost' (using password: NO)'
如先输入mysql,成功启动后输入use mysql,出现如下错误：Access denied for user ''@'localhost' to database 'mysql'
还有，输mysql可以，输mysql -u root就出错了：
Access denied for user 'root'@'localhost' (using password: NO).
The reason is:
是昨日更新ROOT密码时出错
update user set password = '123456' where user =”root” //这样写是错的，密码其实不是123456
应该为update user set password = password ('123456') where user = “root”
具体操作步骤：
关闭mysql:
本文来源gaodai#ma#com搞@@代~&码网 # service mysqld stop
然后:
# mysqld_safe –skip-grant-tables（该命令完成后，可能终端不会提示输入下一命令，下面命令在新开的终端中实现）
启动mysql:
# service mysqld start
mysql -u root
mysql> use mysql
mysql> UPDATE user SET Password=PASSWORD('xxx') WHERE user='root';
mysql> flush privileges;
mysql>/q
