        由于MySQL是開放源代碼的,因此任何人都可以在General Public License的許可下下載并根據(jù)個性化的需要對其進(jìn)行修改。接下來是小編為大家收集的Linux mysql 允許遠(yuǎn)程連接教程,歡迎大家閱讀:

        Linux mysql 允許遠(yuǎn)程連接教程

        1、root用戶登錄到mysql數(shù)據(jù)庫

        /usr/local/mysql/bin/mysql -u root -p (輸入密碼進(jìn)入mysql)

        2、進(jìn)入mysql,輸入如下命令

        use mysql;

        3、查看user表的情況

        SELECT Host,User FROM user;

        //指明主機(jī)名稱,“%”表示匹配所有字符串

        4、 UPDATE user SET Host = '%' WHERE User= 'root' LIMIT 1;

        5、輸入如下命令讓剛才設(shè)置的命令生效

        mysql> flush privileges;

        Query OK, 0 rows affected (0.00 sec)

        注意在mysql 命令行形式下一定要輸入";"

        按照前面五個步驟完成之后,通過控制臺輸入

        [root@linux ~]# mysql -h localhost -u root -p

        Enter password:

        ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

        不讓這么連接數(shù)據(jù)庫

        原因:是因?yàn)閔ost對應(yīng)的user字段是空的,我們需要將其改為root即可

        mysql> select host,user from user;

        +-----------+------+

        | host | user |

        +-----------+------+

        | % | root |

        | 127.0.0.1 | root |

        | linux | |

        | linux | root |

        | localhost | |

        +-----------+------+

        5 rows in set (0.00 sec)

        解決辦法一:

        mysql> update user set user='root' where host='localhost';

        Query OK, 1 row affected (0.00 sec)

        Rows matched: 1 Changed: 1 Warnings: 0

        mysql> flush privileges;

        Query OK, 0 rows affected (0.00 sec)

        解決辦法二:

        將localhost改為本機(jī)的IP地址,則能夠識別了

        [root@linux ~]# mysql -h 172.16.42.68 -u root -p

        Enter password:

        Welcome to the MySQL monitor. Commands end with ; or \g.
