Mysql Error no.1130

mysql資料庫遠端存取設定方法

1、修改localhost
更改 "mysql" 資料庫裡的 "user" 表裡的 "host" 項，從"localhost"改成"%"
mysql>use mysql;
mysql>update user set host = '%' where user = 'root';
mysql>select host, user from user;
mysql>FLUSH PRIVILEGES;

 

2、指定授權
使用myuser/mypassword從任何主機串連到mysql伺服器:
GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

使用myuser/mypassword從ip為192.168.225.166的主機串連到mysql伺服器:
GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.225.166' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

 

3、泛授權
mysql -h localhost -u root
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION; //賦予任何主機上以root身份訪問資料的許可權
mysql>FLUSH PRIVILEGES;

 

解決Mysql無法遠端連線的問題

1、Mysql的連接埠是否正確
通過netstat -ntlp 查看連接埠佔用情況，一般情況下連接埠是3306。在用工具串連MySQl是要用到連接埠。例如My Admin\My Query Browser\MySQl Front等。

2、檢查使用者權限是否正確
mysql庫的user表裡有兩條記錄：host分別為localhost和%(為了安全，%可以換成你需要外部串連的IP)。

3、查看/etc/mysql/my.cnf中,skip-networking 是否已被注掉
需要注掉
報錯：ERROR 2003 (HY000): Can't connect to MySQL server on '192.168.51.112' (111)

 

sudo gedit /etc/mysql/my.cnf
#skip-external-locking

#bind-address        = 127.0.0.1

skip-name-resolve

4、查看iptables是否停掉,沒關的情況下,無法串連
通過：service iptables stop臨時關閉。
報錯：ERROR 2003 (HY000): Can't connect to MySQL server on '192.168.51.112' (113)
