Nginx Service Is Failed On Centos 7

Introduction

Nginx is an open source Web server and a reverse proxy for HTTP, SMTP, POP3 and IMAP protocols. It can also be used for load balancing, caching, media streaming and access control. Nginx is one of the most popular Web servers available, but there can be trouble with it on CentOS 7 systems. In this article, we will explain how to solve common errors in Nginx service on CentOS 7 systems.

Common Error Messages

The most common error messages that you may encounter when trying to start Nginx on CentOS 7 systems are:

  • Could not reliably determine the server’s fully qualified domain name
  • The nginx service failed to start
  • /etc/nginx/nginx.conf: Permission denied

Solve Nginx Server Fails To Start On CentOS 7

If your Nginx service fails to start on CentOS 7, there are a few things you can try to resolve the issue.

1. Check the Log File

The first step to take is to check the Nginx log file. The Nginx log file is located in the /var/log/nginx/ directory. In this directory you will find an “error.log” file which contains information about any errors that may be occurring. Check this file and look for any error messages related to Nginx.

2. Change the Permissions

The error message “/etc/nginx/nginx.conf: permission denied” means that the Nginx configuration file does not have the correct permissions to be readable by the web server. You can change the permissions of the file with the chmod command:

$ sudo chmod 644 /etc/nginx/nginx.conf

This will change the permissions of the file to 644, which will give the Nginx process read access to the file.

3. Set the FQDN

The error message “could not reliably determine the server’s fully qualified domain name” means that the Nginx server cannot determine its fully qualified domain name (FQDN). You can manually set the FQDN for the server with the server_name directive in the Nginx configuration file:

server_name example.com;

Replace “example.com” with the actual domain name of the server.

4. Reload the Configuration File

If you make changes to the Nginx configuration file, you will need to reload it in order for the changes to take effect. You can reload the configuration file with the command:

$ sudo nginx -s reload 

Conclusion

If your Nginx service is failing to start on CentOS 7, follow the steps outlined in this article. Check the log file, change the permissions of the configuration file, set the FQDN and reload the configuration file.
