• nginx -tDisplay normal
• /usr/share/nginx/htmlThere is an html file by default.
• Hostping cent.comCan be pinged. The ip address is 158.
• There is nothing in the nginx log.

Problem

• Host accesshttp://cent.comInaccessible
• Why can't I access it? Did I miss something ??

Solution

• It is indeed a firewall question. Thanks @ _ Zhao for answering this question. I forgot the firewall!
• For centos7firewalld, I saidiptablesWhy ..
• Firewalld is installed and enabled by default. To access nginx, run the following command:
  firewall-cmd --permanent --add-service=http
firewall-cmd --permanent --zone=trusted --add-port=80/tcp
• For other commands, refer to firewalld introduction.

@ Savokiss
FirstcentosTry to use$curl http://127.0.0.1Command to access nginx.
If you can obtainnginx.
Then, the problem basically lies in the firewall,centos 7Firewall usagefirewalld.
So, you needfirewalldAllow80Port.
For specific commandsgoogle.
Hope to solve your problem.
