InterfaceError: 2003: Can't connect to MySQL server on 'localhost:3306' (13 Permission denied)

Question

我正在尝试使用 python CGI 框架在 apache2 服务器上托管应用程序。该程序在编译时工作正常，没有错误。当我在网络浏览器上尝试时，出现错误。

InterfaceError: 2003: Can't connect to MySQL server on 'localhost:3306' (13 Permission denied)

我已经尝试安装 mysql-connector-python 并检查我是否遗漏了任何东西。一切似乎都很好。下面是详细的错误代码。

def connectdb():
    mydb = mx.connect(host='localhost',user='******',passwd='********',database='searchdb')
    cur=mydb.cursor()
    return mydb,cur

尝试访问程序时出错。

  mydb,cur=connectdb()

InterfaceError: 2003: Can't connect to MySQL server on 'localhost:3306' (13 Permission denied)

这是我遇到的错误。熟悉这个问题的朋友请告诉我。

谢谢。

Answer 1

一些要检查的东西，假设这是一台 Linux 机器：

确保您可以使用相同的用户名和密码进行本地连接。 mysql -u [youruser] -p
如果 SELinux 是运行，确保 "httpd_can_network_connect_db" 布尔值设置为开。检查 sudo getsebool httpd_can_network_connect_db。如果返回为 "off,"，则将其设置为 "on" 和 sudo setsebool -P httpd_can_network_connect_db on。（确保包含 -P，否则如果系统重新启动，它将恢复为原始值。）
