提示：注意80端口冲突
如果出不来Welcome to Nginx的内容页面，请从下面原因中依次排查：
1. iptables防火墙和selinux是否关闭。
[root@localhostsbin]# /etc/init.d/iptables stop
#这是关闭防火墙的命令，如果是外网IP生产环境请允许80端口的访问，而不是关闭防火墙
[root@localhostsbin]# chkconfig iptables off
#非正式环境可以禁止防火墙开机自启动，便于学习调式nginx服务。
[root@localhostsbin]# /etc/init.d/iptables status #查看iptablesr 当前状态
2.关闭selinux:
[root@localhostsbin]#setenforce 0 #这是临时关闭方法
[root@localhostsbin]# cat /etc/selinux/config |grep SELINUX=disabled #永久关闭地点
3.通过下面命令确认httpd端口80是否存在:
[root@localhostsbin]# netstat -lnt|grep 80
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN
4.查看是否有httpd进程存在
[root@localhostsbin]# ps -ef|grep nginx
root 10827 1 0 18:35 ? 00:00:00 nginx: master process ./nginx
nginx 10828 10827 0 18:35 ? 00:00:00 nginx:worker process
root 10904 1387 0 18:54 pts/0 00:00:00 grep nginx
5.在服务器本地wget http://192.168.152.130测试
