  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(gè)步驟完成之后,通過控制臺(tái)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(duì)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(shí)別了

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

  Enter password:
