How to Set Up Nginx Virtual Hosts on Ubuntu 22.04: Step-by-Step Guide
Nginx is a powerful web server designed to efficiently manage multiple domains on a single server and IP address using virtual hosts. Virtual hosting allows you to host several websites on one server, each with its own domain name and configuration. In this step-by-step tutorial, we will guide you through the process of setting up Nginx virtual hosts to easily manage multiple websites on your server.
In the Serverspace you can create a server with already installed app "Nginx".
Nginx configuration files
First, you need to install the Nginx package.
apt install nginxAll configuration files for Nginx virtual hosts are stored in the /etc/nginx/sites-available/ folder. The best way is to create a separate file for each web site on the server. Let’s create the first configuration for domain-name.com.
nano /etc/nginx/sites-available/domain-name.comNow insert this configuration there.
server {
listen 80; # Specify the listening port
listen [::]:80; # The same thing for IPv6
root /var/www/domain-name.com/html; # The path to the website files
index index.html index.htm; # Files to display if only the domain name is specified in the address
server_name domain-name.com; # Domain name of this site
location / {
try_files $uri $uri/ =404;
}
}Save and close this file.
Create a folder for the website and place its files there.
mkdir -p /var/www/domain-name.com/htmlAnd set permissions for the folder.
chmod -R 755 /var/wwwEnabling the Nginx virtual host
You need to create a symbolic link to the configuration in the sites-enabled directory to enable the virtual host.
ln -s /etc/nginx/sites-available/domain-name.com /etc/nginx/sites-enabled/Now check the configuration for errors.
nginx -tAnd restart the service.
systemctl restart nginxNow you have a working virtual host for a single domain. You can access it by domain name if the DNS server is configured correctly. Any number of domains can be added to the server in this way.
Disabling Nginx virtual hosts
To disable a virtual host, remove the symbolic link from the sites-enabled folder. To disable returning a standard web page when accessing the server's IP address, you can simply delete the link to the default configuration.
rm /etc/nginx/sites-enabled/defaultRestart the service after that.
systemctl restart nginxFAQ: Common Questions About Nginx Virtual Hosts Setup
- Q: What are Nginx virtual hosts?
A: Virtual hosts allow Nginx to serve multiple websites on a single server and IP address by using separate configuration files for each domain. - Q: How do I enable or disable a virtual host?
A: Enable a virtual host by creating a symbolic link from /etc/nginx/sites-available/ to /etc/nginx/sites-enabled/. To disable it, simply remove the symbolic link and restart Nginx. - Q: Do I need to restart Nginx after changes?
A: Yes, after enabling, disabling, or modifying virtual host configurations, always run nginx -t to check for errors, then restart Nginx with systemctl restart nginx to apply changes. - Q: Can I host unlimited domains on one server?
A: Yes, by creating separate configuration files for each domain and enabling them via symbolic links, you can host as many domains as your server resources allow. - Q: What permissions should I set for website files?
A: Set permissions to 755 for the website directory to ensure Nginx can read the files properly while maintaining security.
