MySQL中出现连接错误:
ERROR 1045 (28000): Access denied for user
----------------------------------------------------------------------------------
1.添加用户
shell>mysql
mysql>use mysql
mysql>grant all privileges on *.* to 'test' identified by 'test' with grant option;
mysql>flush privileges;
[也可以使用下面两种方式建立用户]
------------------------
$1直接操作mysql.user这张表;
$2使用DDL语言,
定义用户:create user test identified by 'test';
删除用户:drop user test
------------------------
2.使用test登录(总是无法连接)
shell>mysql -u test -p
ERROR 1045 (28000): Access denied for user 'test'@'localhost' (using password: YES)
3.查看user表,我们会发现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.删除user.user中值为NULL的,或更新NULL为test
4.1)delete from user where user is NULL
4.2)update user set user='test' where user is NULL
问题解决
另:[我的系统是RHEL4.0]
1.mysql的配置文件my-*.cnf
/usr/local/mysql/
2.初始化数据库
/usr/bin/mysql_install_db
