Nginx页面不能访问排查思路
Nginx页面不能访问排查思路
nginx页面不能访问:
- 检查服务端服务是否启动成功
- 在服务端使用wget和curl测试下返回的是否正常
- 浏览器wget或者curl等软件访问不了Ngixn页面
1. 检查服务端服务是否启动成功
#查看nginx服务是否启动
[root@nginx ~]# ps -ef |grep nginx
root 1316 1 0 15:17 ? 00:00:00 nginx: master process nginx
nginx 1354 1316 0 15:25 ? 00:00:00 nginx: worker process
root 1369 1278 0 15:29 pts/1 00:00:00 grep --color=auto nginx
#检查80端口是否在监听状态
[root@nginx ~]# lsof -i :80
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
nginx 1316 root 6u IPv4 21465 0t0 TCP *:http (LISTEN)
nginx 1354 nginx 6u IPv4 21465 0t0 TCP *:http (LISTEN)
[root@nginx ~]# netstat -antup | grep nginx
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 1316/nginx: master
2. 在服务端使用wget和curl测试下返回的是否正常
[root@nginx ~]# wget 127.0.0.1
--2020-06-04 15:32:21-- http://127.0.0.1/
正在连接 127.0.0.1:80... 已连接。
已发出 HTTP 请求，正在等待回应... 200 OK

[root@nginx ~]# curl 127.0.0.1

以上是检测Nginx在服务端安装及浏览是否正常。
3. 浏览器，wget或者curl等软件访问不了Ngixn页面。
3.1 检查本地selinux和防火墙是否关闭
#检查SEliunx
[root@nginx ~]# getenforce
Disabled
#（1）临时关闭SEliunx
[root@nginx ~]# setenforce 0
#（2）永久关闭SEliunx
[root@nginx ~]# vim /etc/selinux/config
SELINUX=disabled #需要将此行更改为disabled
SELINUXTYPE=targeted
#检查防火墙状态
[root@nginx ~]# systemctl status firewalld.service
#关闭防火墙
[root@nginx ~]# systemctl stop firewalld.service
#永久关闭防火墙，禁止开机自启动
[root@nginx ~]# systemctl disable firewalld.service
3.2 通过本地客服端测试
#第一步：在客服端ping服务端的ip，我这里的的服务端为192.168.200.30
[root@nginx-client ~]# ping 192.168.200.30 -c 5
PING 192.168.200.30 (192.168.200.30) 56(84) bytes of data.

5 packets transmitted, 5 received, 0% packet loss, time 4009ms
rtt min/avg/max/mdev = 0.279/0.438/0.589/0.113 ms
#第二步：在客户端上telnet服务端ip，端口
[root@nginx-client ~]# telnet 192.168.200.30 80
Trying 192.168.200.30...
Connected to 192.168.200.30.
Escape character is '^]'.
#第三步：在客服端使用wget或者curl命令检测。
[root@nginx-client ~]# wget 192.168.200.30
--2020-06-04 15:55:32-- http://192.168.200.30/

3.3 在浏览器访问服务器ip:http://192.168.200.30
注意清理一下缓存呦~~
