Nginx在本地网络中不起作用

Question

os centos 6.3 Nginx在本地网络中不起作用，但它在localhost中有效。由elinks测试。

# ps -ef | grep nginx
root      1447     1  0 Aug07 ?        00:00:00 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf
nginx     1448  1447  0 Aug07 ?        00:00:00 nginx: worker process

# netstat -napt | grep nginx
tcp        0      0 0.0.0.0:80                  0.0.0.0:*                   LISTEN      1447/nginx

# cat /etc/sysconfig/selinux

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
#     targeted - Targeted processes are protected,
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

听起来这不是Nginx的问题。您是否在Nginx访问或错误日志中看到任何访问尝试？如果它是Nginx问题，你应该这样做。

您的netstat输出显示Nginx正在运行并在所有IP上侦听端口80。

尝试使用nmap自行端口扫描并确认检测到端口80上正在运行的内容：

nmap -vv -P0 (server IP address or DNS)

如果它找不到任何东西，听起来好像它被别人阻挡了。与您的网络管理员联系。
