MySQL登錄

mysql -uroot -p密碼
mysql -hip -uroot -p連接目標(biāo)的密碼
mysql --host=ip --user=root --password=連接目標(biāo)的密碼

C:\Users\Administrator>mysql -h 127.0.0.1 -uroot --port=3306 -p

Mysql 命令行連接遠(yuǎn)程數(shù)據(jù)庫

連接遠(yuǎn)程的數(shù)據(jù)庫

mysql --host=ip --user=root --password=連接目標(biāo)的密碼

┌──(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

有兩個(gè)方法

如果你的 mysql 數(shù)據(jù)庫沒有密碼最好創(chuàng)建一個(gè)一密碼

update mysql.user set authentication_string=password('新密碼') where user='用戶名' and Host ='localhost';
update mysql.user set authentication_string=password('admin') where user='用戶名' and Host ='localhost';

1.改表法

是因?yàn)?root 帳號不允許從遠(yuǎn)程登陸，只能在localhost。這個(gè)時(shí)候只要在localhost的那臺電腦，登入mysql后，更改 “mysql” 數(shù)據(jù)庫里的 “user” 表里的 “host” 項(xiàng)，從"localhost"改為"%"

C:\Users\Administrator>mysql -uroot -p -P3306
Enter password: *****

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
mysql> use mysql; # 使用數(shù)據(jù)庫
Database changed
mysql> select user,password,host from user where user='root'; # 先查詢下 有權(quán)限的 用戶 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" 數(shù)據(jù)庫里的 "user" 表里的 "host" 項(xiàng)，從"localhost"改為"%"
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的緩存
Query OK, 0 rows affected (0.00 sec)

執(zhí)行操作之后重啟服務(wù)器

如果有需要改回來在使用數(shù)據(jù)庫之后把 “mysql” 數(shù)據(jù)庫里的 “user” 表里的 “host” 項(xiàng) 從"%“改為"localhost” 之后刷新一下緩存之后重啟 mysql 服務(wù) 即可

mysql> use mysql; # 使用數(shù)據(jù)庫
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的緩存
Query OK, 0 rows affected (0.00 sec)

2. 授權(quán)法。例如，你想某個(gè)用戶名比如 myuser 和對應(yīng)的密碼從任何主機(jī)連接到mysql服務(wù)器的話。

/*myuser mypassword 為對應(yīng)的 用戶迷宮和密碼 */
GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

如果你想允許用戶myuser從ip為192.168.1.3的主機(jī)連接到mysql服務(wù)器，并使用mypassword作為密碼

/*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的緩存
Query OK, 0 rows affected (0.00 sec)

取消授權(quán)

# 查看授權(quán)的所有用戶
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為指定的用戶，%為任意登錄的地址。
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的緩存
Query OK, 0 rows affected (0.00 sec)

然后重啟 mysql 服務(wù)
