Mysql 命令行 连接远程数据库
连接 远程的数据库

┌──(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
1
2
|
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"%"

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。
1
2
|
/*myuser mypassword 为对应的 用户迷宫和密码 */ 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
1

|
/*例如 */ 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

然后 重启 mysql 服务
