[摘要]MySQL中出現(xiàn)連接錯誤:ERROR 1045 (28000): Access denied for user--------------------------------------------...
MySQL中出現(xiàn)連接錯誤:
ERROR 1045 (28000): Access denied for user
----------------------------------------------------------------------------------
1.添加用戶
shell>mysql
mysql>use mysql
mysql>grant all privileges on *.* to 'test' identified by 'test' with grant option;
mysql>flush privileges;
[也可以使用下面兩種方式建立用戶]
------------------------
$1直接操作mysql.user這張表;
$2使用DDL語言,
定義用戶:create user test identified by 'test';
刪除用戶:drop user test
------------------------
2.使用test登錄(總是無法連接)
shell>mysql -u test -p
ERROR 1045 (28000): Access denied for user 'test'@'localhost' (using password: YES)
3.查看user表,我們會發(fā)現(xiàn)user表中的user字段有NULL
mysql> select host,user from user;
+------------------+------+
host user
+------------------+------+
% test
localhost
localhost root
test.saeg.com.cn
test.saeg.com.cn root
+------------------+------+
5 rows in set (0.00 sec)
4.刪除user.user中值為NULL的,或更新NULL為test
4.1)delete from user where user is NULL
4.2)update user set user='test' where user is NULL
問題解決
另:[我的系統(tǒng)是RHEL4.0]
1.mysql的配置文件my-*.cnf
/usr/local/mysql/
2.初始化數(shù)據(jù)庫
/usr/bin/mysql_install_db
Microsoft Access在很多地方得到廣泛使用,例如小型企業(yè),大公司的部門。
