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
