How to setup Nginx server blocks for multiple sites - Ubuntu
=====================================================
Edited: May 5th 2025

=====================================================
Setting up nginx server blocks is a process that allows you to host multiple websites on a single server.
It is a useful technique for those who want to host multiple websites or applications on a single machine,
as it allows you to use a single IP address and port to host multiple domains. In this article, we will
explain how to set up nginx server blocks on a Ubuntu server.
Prerequisites
* Install Nginx for Ubuntu
- https://decode.sh/installing-nginx-on-ubuntu
Step 1:
Allow Nginx to pass through your firewall.
+---------------------------------------------------+
| |
| sudo ufw allow 'Nginx HTTP' |
| |
+---------------------------------------------------+
Step 2:
Create a directory for your site and configuration files.
+---------------------------------------------------+
| |
| sudo mkdir -p /var/www/{{your_domain}}/html |
| |
+---------------------------------------------------+
Set the ownership of the directory to the $USER environment variable.
+----------------------------------------------------------+
| |
| sudo chown -R $USER:$USER /var/www/{{your_domain}}/html |
| |
+----------------------------------------------------------+
This allows you to read, write, and execute the files and lets other users read and execute files.
+---------------------------------------------------+
| |
| sudo chmod -R 755 /var/www/{{your_domain}} |
| |
+---------------------------------------------------+
Make a sample page in the directory you just created.
+---------------------------------------------------+
| |
| sudo nano /var/www/{{your_domain}}/html/index.html|
| |
+---------------------------------------------------+
Add this sample HTML file
+---------------------------------------------------+
| |
| |
| |
| Welcome to {{your_domain}}!! |
| |
| |
| Success!
|
| |
| |
| |
| |
+---------------------------------------------------+
Step 3:
Creating the server block
+----------------------------------------------------------+
| |
| sudo nano /etc/nginx/sites-available/{{your_domain}} |
| |
+----------------------------------------------------------+
Add this to the created file. Change the www to any sub-domain you want.
Port
Replace {{your_port}} with the correct port you want to be set.
+------------------------------------------------------------+
| |
| server { |
| listen 80; |
| listen [::]:80; |
| |
| root /var/www/{{your_domain}}/html; |
| index index.html index.htm index.nginx-debian.html |
| |
| server_name {{your_domain}}; |
| |
| location / { |
| proxy_pass http://localhost:{{your_port}}; |
| proxy_http_version 1.1; |
| proxy_set_header Upgrade $http_upgrade; |
| proxy_set_header Connection 'upgrade'; |
| proxy_set_header Host $host; |
| proxy_cache_bypass $http_upgrade; |
| } |
| } |
| |
+------------------------------------------------------------+
Once added save the file and then we need to link the configuration file to the sites-enabled directory
+-------------------------------------------------------------------------------------+
| |
| sudo ln -s /etc/nginx/sites-available/{{your_domain}}/etc/nginx/sites-enabled/ |
| |
+-------------------------------------------------------------------------------------+
This will keep both configuration files in sync between sites-available and sites-enabled
Next to prevent a possible hash bucket memory problem, open /etc/nginx/nginx.conf.
+---------------------------------------------------+
| |
| sudo nano /etc/nginx/nginx.conf |
| |
+---------------------------------------------------+
un-comment the line below in the http block
+---------------------------------------------------+
| |
| server_names_hash_bucket_size 64; |
| |
+---------------------------------------------------+
Step 4:
Now everything should be set up, you can run the command to make sure all the formatting is done properly.
+---------------------------------------------------+
| |
| sudo nginx -t |
| |
+---------------------------------------------------+
If no warning show up you are good to restart the server.
+---------------------------------------------------+
| |
| sudo systemctl restart nginx |
| |
+---------------------------------------------------+
Setting up multiple sites
To configure more than one domain on the same server just repeat steps 2-4.
