在 Ubuntu 上打开一个端口 [英] Opening a port on Ubuntu

问题描述

我正在尝试在我的 Ubuntu 机器上打开端口，以允许我使用外部程序连接 Mongo.我运行了这个命令行来打开一个新端口:

I am trying to open up port on my Ubuntu machine to allow me to connect the Mongo using an external program. I ran this which is the command line to open a new port:

sudo iptables -A INPUT -p tcp --dport 27017 -j ACCEPT

但是当我运行它来检查新规则是否存在时...

but when I ran this to check if the new rule was there...

sudo netstat -ntlp | grep LISTEN

...新端口不在列表中 - 有什么想法吗?

...the new port wasn't in the list - any ideas?

推荐答案

我认为 mangodb 实例没有启动，除此之外，sudo netstat -ntlp |grep LISTEN 给出正在使用的活动端口列表，首先启动你的 Mango 实例 sudo service mongodb start ，然后运行这个命令 sudo netstat -ntlp |grep LISTEN 如果您在列表中找到 27017，则 sudo iptables -L 查一下您的 iptable 规则是否添加.如果它在该列表中还不错，sudo iptables -A INPUT -p tcp --dport 27017 -j ACCEPT你可以在@http://docs.mongodb.org/manual/tutorial/configure-linux-iptables-firewall/

I think the mangodb instance was not started, apart from that ,sudo netstat -ntlp | grep LISTEN gives the list ports that are active are being used now, first start your Mango instance sudo service mongodb start , then run this command sudo netstat -ntlp | grep LISTEN if you find 27017 in the list, then sudo iptables -L chack your iptable rule is added or not. If it is in that list good else, sudo iptables -A INPUT -p tcp --dport 27017 -j ACCEPT you can get more details on mangodb port and traffic @ http://docs.mongodb.org/manual/tutorial/configure-linux-iptables-firewall/
