mysql 本地ip访问无法连接ERROR 1045 (28000)
错误：ERROR 1045 (28000): Access denied for user 'test'@'vm4' (using password: YES)
不知什么原因，本地IP访问不了本地数据库
重新创建授权新用户，死活进不去，测试如下：
1、增加用户、授权
mysql> grant all privileges on *.* to 'test'@'%' identified by 'test123';
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql> exit
Bye
[[email protected] ~]# mysql -h192.168.1.204 -utest -ptest123
Warning: Using a password on the command line interface can be insecure.
ERROR 1045 (28000): Access denied for user 'test'@'vm4' (using password: YES)
检查思路：
1、查看
mysql> show variables like '%bind%';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| bind_address | * |
+---------------+-------+
1 row in set (0.00 sec)
2、查看
mysql> select user,host,password from user;
对应的用户host是不是允许ip访问
mysql> select user,host,password from mysql.user;
+---------------+---------------+-------------------------------------------+
| user | host | password |
+---------------+---------------+-------------------------------------------+
| root | localhost | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |
| root | vm4 | |
| root | 127.0.0.1 | |
| root | ::1 | |
| | localhost | |
| | vm4 | |
| test | % | *676243218923905CF94CB52A3C9D3EB30CE8E20D |
| admin | % | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |
| admin | localhost | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |
都没有问题
结果发现奇怪的空用户
此时：mysql -hvm4 是可以直接登录的
因此删除 2标记
重新登录
[[email protected] ~]# mysql -h192.168.1.204 -utest -ptest123

问题总结：ERROR 1045 (28000): Access denied for use类似问题，一定查看user表，分析用户情况
