置SQLServer,允许远程连接

依照地方的小说一步步配置后,远程连接出现下边所示的报错(Navicat 和 SQL
Server Management Studio)

SQL Server Management Studio的报错音讯为:

在与 SQL Server
建立连接时出现与网络有关的或特定于实例的错误。未找到或不能访问服务器。请表达实例名称是否科学并且
SQL Server 已配备为允许远程连接。 (provider: Named Pipes Provider,
error: 40 – 不可能开拓到 SQL Server 的连日) (Microsoft SQL Server,错误:
53)。

后来查了无数解决办法,均以败诉告终。后来无意发现到,远程数据库所在云服务器的安全组未开放对该端口的长距离访问权限,以自己所用的阿里云为例,在安全组->配置规则->快捷创立规则
中,添加MS SQL的1433端口。若为新创设的安全组,还需重启服务器才可生效。
