置SQLServer,允许远程连接

根据上面的稿子一步步布署后,远程连接出现上面所示的报错(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谬误。未找到或无法访问服务器。请表明实例名称是不是科学并且
SQL Server 已安顿为允许远程连接。 (provider: Named Pipes Provider,
error: 40 – 不能打开到 SQL Server 的连接) (Microsoft SQL Server,错误:
53)。

新生查了成百上千化解措施,均以战败告终。后来懒得发现到,远程数据库所在云服务器的安全组未开放对该端口的远程访问权限,以自家所用的阿里云为例,在安全组->配置规则->飞速创制规则
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。
