连接linode mongodb服务器时出现连接错误
我已经安装了mogodb linode“mongodb-app”及其运行..创建的用户和集合并能够从shell访问它 现在尝试从本地连接到服务器但服务器超时 '''

在运行 mongodb 的 Linux 服务器上，运行以下两个命令：
iptables -A INPUT -s; -p tcp --destination-port 27017 -m state --state NEW,ESTABLISHED -j ACCEPT
iptables -A OUTPUT -d; -p tcp --source-port 27017 -m state --state ESTABLISHED -j ACCEPT 取自 https://docs.mongodb.com/manual/tutorial/configure-linux-iptables-firewall/#traffic-to-and-from-mongod-instances
On your linux server where mongodb is running, run these two commands:
iptables -A INPUT -s <ip-address-of-your-app> -p tcp --destination-port 27017 -m state --state NEW,ESTABLISHED -j ACCEPTiptables -A OUTPUT -d <ip-address-of-your-app> -p tcp --source-port 27017 -m state --state ESTABLISHED -j ACCEPTTaken from https://docs.mongodb.com/manual/tutorial/configure-linux-iptables-firewall/#traffic-to-and-from-mongod-instances
