Cara 404 Not Found Nginx
What is 404 Not Found Error?
The HTTP 404 Not Found Error is a common browser error server webpages display when a requested page is not found. This is made clear by the fact that the URL demands a content that the server is unable to retrieve. The “404 Not Found” error is an HTTP response status code that means a web page or other resource could not be found on the server.
To put it simply, If we request an address from a server (located within web hosting), and experience an error that reads ‘404 Not Found’, it is because the requested address does not exist within the server. This can either be due to incorrect input from the user, such as typing in a wrong URL, or due to an error on the server’s behalf.
What is Nginx?
Nginx is a web server created by Igor Sysoev. It is a software which is popularly known as a reverse proxy, load balancer and HTTP cache. Nginx is well known in the industry for its high performance, stability, rich feature set and low resource consumption. It is used by some of the world’s largest websites and services including Netflix, Dropbox and WordPress.
Nginx is capable of serving both static and dynamic content. It can support multiple authentication methods and resides as a proxy server between the public and its own internal network. Nginx is known to be fast and efficient as it leverages an event-driven (asynchronous) architecture, rather than a traditional ‘threaded’ architecture.
How to Fix 404 Not Found Error on Nginx Server?
The 404 Not Found error indicates that the web server cannot find the requested resource. If you are running a Nginx server, there are several ways to fix this issue. Here are the steps:
- Check whether the resource exists – ensure that the file/folder exists in its directory.
- Check the Nginx configuration – open the nginx.conf file and make sure that it is set up correctly.
- Check the document root – verify that the document root points to the correct directory.
- Check the permissions – verify that the web user has sufficient permissions to access the requested file/directory.
This process should help you identify the problem and allow you to take the necessary steps to fix it. If you are still experiencing difficulties, you may need to contact your hosting provider and ask them to help you troubleshoot the issue.
How to Redirect 404 Not Found Errors in Nginx?
If you find yourself dealing with the 404 Not Found error on your Nginx server, you may want to consider implementing a redirect for those errors. A redirect will send users to a specific page, such as the homepage or a custom error page, when they enter a URL not found on your server. This can help improve the user experience and help prevent users from leaving your site altogether.
To configure a redirect, open the nginx.conf file and edit the server block. Add the following code example at the very end of the server block:
error_page 404 /404.html;
The “/404.html” above is the path to the page you want to redirect users to if they get a 404 Not Found error. Save the changes and reload Nginx. Now all 404 errors will be redirected to the specified page.
What are the Other Errors Returned by Nginx?
Apart from 404 Not Found, Nginx can return several other errors. Here are some of the most common ones:
- 400 Bad Request – The server cannot or will not process the request. This is usually due to a malformed request.
- 403 Forbidden – The user does not have permission to access the requested resource.
- 408 Request Timeout – The server did not receive a complete request from the client in time.
- 500 Internal Server Error – This indicates that a server-side error occurred. Check the Nginx error log for details.
- 502 Bad Gateway – This indicates that the server has received an invalid response from an upstream server.
- 503 Service Unavailable – This indicates that the server is unable to handle the request due to capacity problems.
If you are troubleshooting Nginx errors, it is important to be familiar with these codes and understand what they mean. If you are in doubt, it is best to contact your hosting provider for assistance.
