禁用SELINUX时无法从外部访问nginx

我刚刚安装了CentOS 6.5服务器，并在其上安装了nginx

我已经禁用了SELINUX并重新启动了服务器，但除了主机本身之外，其他服务器仍然无法访问nginx

这是我的nginx配置：

# For more information on configuration, see:

#   * Official Russian Documentation: http://nginx.org/ru/docs/

user              nginx;
worker_processes  4;

error_log  /var/log/nginx/error.log;
#error_log  /var/log/nginx/error.log  notice;
#error_log  /var/log/nginx/error.log  info;

pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    # Load config files from the /etc/nginx/conf.d directory
    # The default server is in conf.d/default.conf
    include /etc/nginx/conf.d/*.conf;

}

我做错了什么？

解决了，IPTABLES中有一条规则阻止了所有传入的连接

iptables -L INPUT -n --line-numbers
iptables -D INPUT <N>
service iptables save
service iptables restart

解决了这个问题
