的MySQL連接被拒絕

Question

我已經擡頭就如何解決這一問題並沒有什麼工作，到目前爲止， 我得到這個錯誤 無連接可以作出，因爲目標機器積極地拒絕它 我使用Linux的每一個教程centos7 mysql版本 mysql版本14.14 Distrib 5.6.32，用於Linux（x86_64）使用EditLine封裝 blow is my.cnf 我還必須創建自己的my.cnf，因爲當我安裝mysql時它沒有一個位於我把它放到etc/my.cnf中，它運行的是cnf，因爲它將mysql從嚴格模式中取出。

好吧，我假設你已經安裝了這個完全不同的機器上（而不是在虛擬主機上的Windows中）。

您需要確保首先在您的數據庫服務器上打開端口3306。你可以用端口檢查器來檢查（有很多免費的在線）。

然後，用戶嘗試連接的用戶需要確保該用戶可以訪問源IP地址（即Windows機器上的IP）。這可以通過mysql提示符下面的代碼完成。

GRANT ALL PRIVILEGES ON <your db name>.* TO <your user>@<your ip> IDENTIFIED BY '<your password>'; 

不太安全的選項是通過使用％通配符來允許所有入站IP。

之後，您需要運行以下命令。

FLUSH PRIVILEGES; 

應該是這樣。
