How to Set Up Virtual Hosts for Apache Servers

How to Set Up Virtual Hosts for Apache Servers

Setting up virtual hosts for Apache servers is essential for managing multiple websites on a single server. This process allows you to configure different domain names and their respective content seamlessly. Follow these steps to set up virtual hosts effectively.

Step 1: Install Apache

If you haven’t installed Apache yet, you can do so with the following command:

sudo apt-get update
sudo apt-get install apache2

After installation, make sure Apache is running by accessing http://localhost in your web browser. You should see the default Apache welcome page.

Step 2: Create Directory Structure

For each website you want to host, you need to create a separate directory. Use the following command to create directories:

sudo mkdir -p /var/www/html/example.com/public_html
sudo mkdir -p /var/www/html/anotherexample.com/public_html

Replace example.com and anotherexample.com with your actual domain names. Additionally, set the appropriate permissions:

sudo chown -R $USER:$USER /var/www/html/example.com/public_html
sudo chown -R $USER:$USER /var/www/html/anotherexample.com/public_html

Step 3: Create Sample Index File

Create a sample index file for each website to confirm that the setup works:

echo "Hello, this is example.com" | sudo tee /var/www/html/example.com/public_html/index.html
echo "Hello, this is anotherexample.com" | sudo tee /var/www/html/anotherexample.com/public_html/index.html

Step 4: Set Up Virtual Host Files

Next, create virtual host configuration files for each domain in the Apache configuration directory:

sudo nano /etc/apache2/sites-available/example.com.conf

Then, add the following content:

<VirtualHost *:80>
    ServerAdmin webmaster@example.com
    ServerName example.com
    ServerAlias www.example.com
    DocumentRoot /var/www/html/example.com/public_html
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

Repeat this process for the second domain:

sudo nano /etc/apache2/sites-available/anotherexample.com.conf

Add the similar content with the corresponding domain names:

<VirtualHost *:80>
    ServerAdmin webmaster@anotherexample.com
    ServerName anotherexample.com
    ServerAlias www.anotherexample.com
    DocumentRoot /var/www/html/anotherexample.com/public_html
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

Step 5: Enable the Virtual Host Files

Enable the virtual host files using the following commands:

sudo a2ensite example.com.conf
sudo a2ensite anotherexample.com.conf

Then, disable the default site configuration:

sudo a2dissite 000-default.conf

Step 6: Check Configuration and Restart Apache

Before restarting Apache, check your configuration for any errors:

sudo apache2ctl configtest

If the configuration is correct, you can now restart Apache to apply the changes:

sudo systemctl restart apache2

Step 7: Update Hosts File (Optional)

If you are testing locally, you can map the domains to your server's IP address by editing your hosts file:

sudo nano /etc/hosts

Add the following lines at the end:

127.0.0.1 example.com
127.0.0.1 anotherexample.com

Save and exit the editor. You should now be able to access your websites by entering the domain names in your web browser.
