404 Not Found Nginx Ubuntu
What is 404 Not Found Error?
The 404 Not Found error is one of the most irritating status codes that can appear when someone attempts to visit a webpage. It’s a client-side error, which means there was a problem in your browser or computer that stopped the page from loading correctly. Generally, these errors are most common with people who have an outdated web browser, poor Wi-Fi connection, or an overloaded server.
The 404 Not Found error is one of the more common web errors that you may encounter. It is an HTML status code returned by your web server when users request a page that is not found. The error message itself is displayed as a web page, so it’s quite obvious to the user what has happened.
Most of the time, the 404 Not Found error is caused by simply typing the wrong URL or page name in the address bar. It’s also possible that someone has removed the page in question or it was never created in the first place. Additionally, a corrupted cookie or cached page could also lead to the error message.
How Does Nginx Handle 404 Not Found Errors?
The Nginx web server is a popular choice for hosting web applications. It has a powerful feature set and can serve up static content quickly and efficiently. As with most web servers, it also needs a way of dealing with errors when visitors attempt to access non-existent pages.
By default, Nginx will return a 404 Not Found error code when users request non-existent pages. This error message can be customized and can be made more user-friendly by adding more details about the cause of the error.
Furthermore, it is also possible to redirect any requests for non-existent pages to a custom “404 Not Found” page. This page can contain more help or an explanation of why the page is not available.
By using Nginx’s error_page directive, it is possible to redirect requests for non-existent pages to a custom page. In addition to this, the page can also contain an element that allows users to search for other pages in the web application.
How to Set Up NGINX 404 Not Found Error Handling on an Ubuntu Server?
Setting up NGINX on an Ubuntu server to handle 404 not found errors is fairly straightforward. To begin with, we need to install NGINX on the server. This can be done with the following command:
sudo apt-get install nginx
Once this is done, we need to create a custom 404 not found error page. This page should provide more information about the error, as well as any suggestions for users to find the page they are looking for. The file can be placed in the /var/www/html directory and can be named anything, as long as it ends with .html or .php.
After the page is created, we need to modify the NGINX configuration file, which is located at /etc/nginx/sites-enabled/default. This file should be modified to include the following content:
error_page 404 /404.html;
Once this is added, we can restart NGINX using the following command:
sudo service nginx restart
This will activate the 404 not found error page that we specified earlier. Visitors to the server who request a page that does not exist will now be redirected to the custom 404 error page.
What Other Errors Can Nginx Handle?
Nginx can handle a variety of different errors. Additionally, the configuration can be changed to redirect requests to different pages. This includes errors such as 301 redirects, 403 forbidden errors, 500 Internal Server Errors, 502 Bad Gateway Errors, and 503 Service unavailable errors.
These errors can be managed by adding directives for each of them in the configuration file. In addition to these errors, Nginx can also serve up custom pages for 50x and 40x HTTP status codes. This makes it easy to present a consistent set of pages to visitors regardless of which type of error is encountered.
What is an Example of 404 Not Found Error in Ubuntu?
A 404 not found error in Ubuntu can occur for a variety of reasons. Typically, these errors occur when a user attempts to access a non-existent page or file. This can be caused by a user typing the wrong page address, or if the page or file has been removed or never existed in the first place.
An example of a 404 not found error in Ubuntu is as follows:
404 Not Found
The requested URL/page was not found on this server.
Apache/2.4.18 (Ubuntu) Server at example.com Port 443
The error message itself is fairly self-explanatory. It indicates that the page was not found on the server, likely due to it not existing in the first place. Anytime the user visits a page and the server is unable to find it, the 404 Not Found error will be displayed.
