Let’s dive into the solution!
How to Fix nginx Error Duplicate Default Server
There are several ways to fix the nginx error duplicate default server. Let’s take a look at some of the most effective solutions:
1. Check Your Configuration Files
The first thing you should do is check your configuration files to make sure that you don’t have any duplicate server blocks. You can do this by running the following command:
sudo nginx -t
This command will check your configuration files for any syntax errors or duplicate server blocks. If it finds any issues, it will display an error message that will help you identify the problem.
2. Remove Duplicate Default Server Blocks
If the command above reveals that you have duplicate default server blocks, you’ll need to remove them. To do this, open your configuration files and search for server blocks with the same server name and port number. Delete the duplicates so that you only have one default server block.
3. Use Include Files
If you have a large number of server blocks in your configuration files, it can be challenging to identify and remove duplicates manually. In this case, you can use include files to separate your server blocks and make them easier to manage.
Include files are separate configuration files that you can include in your main configuration file. This way, you can organize your server blocks into different files and easily identify duplicates.
4. Use Regular Expressions
If you have multiple server names with the same prefix, you can use regular expressions to group them together. This can make it easier to manage your configuration files and avoid duplicate default server blocks.
For example, if you have three server blocks with the following server names:
server_name example.com;server_name www.example.com;server_name api.example.com;
You can use regular expressions to group them together like this:
server_name ~^(www\.)?example\.com$;
This will match all three server names and prevent duplicate default server blocks.
5. Restart nginx
Once you’ve made the necessary changes to your configuration files, you’ll need to restart nginx to apply the changes. You can do this by running the following command:
sudo service nginx restart
This will restart nginx and apply the changes you’ve made to your configuration files. Your website should now be accessible.
