PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h tffserver01 password 'new-password'
Alternatively you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
Please report any problems with the /usr/bin/mysqlbug script!

登录mysql时报以上错误，解决方法如下：重置密码 mysqladmin -uroot -p password 'newpassword'
# /etc/init.d/mysql stop
# mysqld_safe --user=mysql --skip-grant-tables --skip-networking &
# mysql -u root mysql
mysql> UPDATE user SET Password=PASSWORD('newpassword') where USER='root';
mysql> FLUSH PRIVILEGES;
mysql> quit
# /etc/init.d/mysql restart # mysql -uroot -p Enter password: < 输入新设的密码newpassword> mysql>
如果可以用navicat工具连过去，查看用户权限，修改用户权限都是很方便的，但很多时候MySQL都是只允许localhost访问，这时就只能用命令了
以前用
mysql> select * from mysql.user where user='username';
今天发现这个更方便：
mysql> show grants for username@localhost; 或mysql> show grants for root@'localhost'; 或mysql> show grants for root@'%'; 或mysql> show grants;
show可以看到很多东西
show create database dbname; 这个可以看到创建数据库时用到的一些参数。
show create table tickets; 可以看到创建表时用到的一些参数
