ByeMysql 命令行 连接远程数据库
连接 远程的数据库
mysql --host=ip --user=root --password=连接目标的密码
┌──(root㉿kali)-[~]
└─# mysql -h 69.45.123.1 -uroot --port=3307 -p
Enter password:
ERROR 1130 (HY000): Host '69.45.123.128' is not allowed to connect to this MySQL server有两个方法
如果 你的 mysql 数据库没有 密码 最好创建一个一密码
update mysql.user set authentication_string=password('新密码') where user='用户名' and Host ='localhost';
update mysql.user set authentication_string=password('admin') where user='用户名' and Host ='localhost';1.改表法
是因为 root 帐号不允许从远程登陆，只能在localhost。这个时候只要在localhost的那台电脑，登入mysql后，更改 “mysql” 数据库里的 “user” 表里的 “host” 项，从"localhost"改为"%"
C:\Users\Administrator>mysql -uroot -p -P3306

mysql> use mysql; # 使用数据库
Database changed
mysql> select user,password,host from user where user='root'; # 先查询下 有权限的 用户 的 host 是什么
+------+-------------------------------------------+-----------+
| user | password | host |
+------+-------------------------------------------+-----------+
| root | *4ACFE3202A5FF5CF467898FC58AAB1D615029441 | localhost |
| root | *4ACFE3202A5FF5CF467898FC58AAB1D615029441 | 127.0.0.1 |
| root | *4ACFE3202A5FF5CF467898FC58AAB1D615029441 | ::1 |
+------+-------------------------------------------+-----------+
3 rows in set (0.00 sec)
# 修改 "mysql" 数据库里的 "user" 表里的 "host" 项，从"localhost"改为"%"
mysql> update user set host = '%' where user = 'root' and host='localhost';
Query OK, 0 rows affected (0.00 sec)
Rows matched: 0 Changed: 0 Warnings: 0
mysql> flush privileges; # 刷新一下 mysql的缓存
Query OK, 0 rows affected (0.00 sec)执行操作之后 重启服务器
如果有需要 改回来 在使用 数据库之后 把 “mysql” 数据库里的 “user” 表里的 “host” 项 从"%“改为"localhost” 之后刷新一下缓存之后 重启 mysql 服务 即可
mysql> use mysql; # 使用数据库
Database changed
mysql> update user set host = 'localhost' where user = 'root' and host='%';
Query OK, 0 rows affected (0.00 sec)
Rows matched: 0 Changed: 0 Warnings: 0
mysql> flush privileges; # 刷新一下 mysql的缓存
Query OK, 0 rows affected (0.00 sec)2. 授权法。例如，你想 某个用户名 比如 myuser 和对应的密码 从任何主机连接到mysql服务器的话。
GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;如果你想允许用户myuser从ip为192.168.1.3的主机连接到mysql服务器，并使用mypassword作为密码
GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.1.3' IDENTIFIED BY '1235' WITH GRANT OPTION;mysql> flush privileges; # 刷新一下 mysql的缓存
Query OK, 0 rows affected (0.00 sec)取消授权
# 查看授权的所有用户
mysql> SELECT DISTINCT CONCAT('User: ''',user,'''@''',host,''';') AS query FROM mysql.user;
+---------------------------+
| query |
+---------------------------+
| User: 'root'@'127.0.0.1'; |
| User: 'root'@'::1'; |
| User: ''@'localhost'; |
| User: 'root'@'localhost'; |
+---------------------------+
4 rows in set (0.00 sec)
# revoke all on *.* from 'username'@'%'; username为指定的用户，%为任意登录的地址。
mysql> revoke all on *.* from 'root'@'192.168.1.3';
Query OK, 0 rows affected (0.00 sec)
# 然后再次
mysql> flush privileges; # 刷新一下 mysql的缓存
Query OK, 0 rows affected (0.00 sec)
然后 重启 mysql 服务
