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!

登錄mysql時報以上錯誤，解決方法如下：重置密碼 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: < 輸入新設的密碼newpassword> mysql>
如果可以用navicat工具連過去，查看用戶權限，修改用戶權限都是很方便的，但很多時候MySQL都是只允許localhost訪問，這時就只能用命令了
以前用
mysql> select * from mysql.user where user='username';
今天發現這個更方便：
mysql> show grants for username@localhost; 或mysql> show grants for root@'localhost'; 或mysql> show grants for root@'%'; 或mysql> show grants;
show可以看到很多東西
show create database dbname; 這個可以看到創建數據庫時用到的一些參數。
show create table tickets; 可以看到創建表時用到的一些參數
