nginx頁面不能訪問
1. 檢查服務端服務是否啓動成功
[root@shizhan02 html]# ps -ef |grep nginx #查看nginx服務是否啓動
root 1609 1 0 16:46 ? 00:00:00 nginx: master process nginx
nginx 1610 1609 0 16:46 ? 00:00:00 nginx: worker process
root 1898 1593 0 18:09 pts/0 00:00:00 grep nginx[root@shizhan02 html]# lsof -i :80 #檢查80端口是否在監聽狀態
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
nginx 1609 root 6u IPv4 11948 0t0 TCP *:http (LISTEN)
nginx 1610 nginx 6u IPv4 11948 0t0 TCP *:http (LISTEN)[root@shizhan02 html]# netstat -lnt |grep 80
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 2.在服務端使用wget和curl測試下返回的是否正常
[root@shizhan02 html]# wget 127.0.0.1
--2017-11-20 18:16:58-- http://127.0.0.1/

[root@shizhan02 html]# curl 127.0.0.1 #返回頁面的值表示正常。

以上是檢測Nginx在服務端安裝及瀏覽是否正常。
3.瀏覽器，wget或者curl等軟件訪問不了Ngixn頁面。
1. 關閉SEliun
```
[root@shizhan02 html]# getenforce #查看iptables狀態，是否爲關閉，以下爲關閉狀
態，
Disabled
[root@shizhan02 html]# vim /etc/selinux/config #永久關閉iptalbes
SELINUX=disabled #需要將此行更改爲disabled
SELINUXTYPE=targeted
[root@shizhan02 html]# setenforce 0 #臨時關閉iptables的方法，如果臨時能夠訪問
了，那麼久使用下面的方法添加80端口在iptables的配置文件上
setenforce: SELinux is disabled
[root@shizhan02 html]# service iptables status #檢查iptables
Table: filter
Chain INPUT (policy ACCEPT)
num target prot opt source destination
Chain FORWARD (policy ACCEPT)
num target prot opt source destination
Chain OUTPUT (policy ACCEPT)
num target prot opt source destination
問題不是出在nginx上，而是出在iptable上，在iptable上添加80端口
Linux代碼 收藏代碼
#vi /etc/sysconfig/iptables
//在倒數第二行加入80端口
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j
ACCEPT
//重啓iptables
#/etc/init.d/iptables restart
再通過ip訪問 ok~ 沒問題了
```
2. 通過本地客服端測試
第一步：在客服端ping服務端的ip，我這裏的的服務端爲192.168.1.202
```
[root@shizhan02 html]# ping 192.168.1.202
PING 192.168.1.202 (192.168.1.202) 56(84) bytes of data.
64 bytes from 192.168.1.202: icmp_seq=1 ttl=64 time=0.014 ms
64 bytes from 192.168.1.202: icmp_seq=2 ttl=64 time=0.024 ms
^C
--- 192.168.1.202 ping statistics ---
2 packets transmitted, 2 received, 0% packet loss, time 1814ms
rtt min/avg/max/mdev = 0.014/0.019/0.024/0.005 ms
#提示按ctrl+c結束
```
第二步：在客戶端上telnet服務端ip，端口
```
[root@shizhan02 html]# telnet 192.168.1.202 #返回如下信息表示鏈接成功
Trying 192.168.1.202...
telnet: connect to address 192.168.1.202: Connection refused
```
第三步：在客服端使用wget或者curl命令檢測。
```
[root@shizhan02 html]# curl -i 192.168.1.202
HTTP/1.1 200 OK
Server: nginx/1.13.6

3. 在瀏覽器訪問輸入如下的內容，服務器ip.
http://192.168.1.202/
這裏有一個小小的坑，希望大家注意一下，使用瀏覽器輸入ip訪問的時候，注意清空一下緩存，或者重新打開一下瀏覽器，有可能讓你一直刷新不出頁面。
