nginx听了端口80。我的配置在 /etc/nginx/conf.d/default.conf
nginx did listen to port 80. Here is my config in /etc/nginx/conf.d/default.conf
server {
listen 80;

我使用公共ip在云主机上运行nginx,但是我无法从公共网络因为连接超时。
I'm running nginx on cloud host with a public ip, but I can't access that ip from public network because connection timeout.
首先:
使用tcpdump检查u是否尝试连接服务器u需要。 br>
at dest server: tcpdump -i your_wan_if port 80
(例如: tcpdump -i venet0 port 80
)
本地主机上的
: telnet external_ip 80
如果u会看到任何活动从ur ip - 好。
First:
Use tcpdump to check if u trying to connect server u need.
at dest server:tcpdump -i your_wan_if port 80
(Ex: tcpdump -i venet0 port 80
)
at local host:telnet external_ip 80
if u will see any activity from ur ip - nice.
第二:
检查selinux和防火墙。尝试禁用它们一段时间并检查。
Second:
check selinux and firewall. try to disable them for few moments and check.
(如果你知道如何配置iptables - 不要知道 - 使用google不要google - 使用这个: iptables -I INPUT 4 -p tcp --dport 80 -j ACCEPT
)
(if u know how to configure iptables - do it. Dont know - use google. Dont want google - use this:
iptables -I INPUT 4 -p tcp --dport 80 -j ACCEPT
