How to Set Up Apache Server on Ubuntu
Step 1: Update Ubuntu
Before installing Apache, ensure that your Ubuntu operating system is up to date. Type the following command in your terminal:
sudo apt update && sudo apt upgrade -y
Step 2: Install Apache
To install Apache on Ubuntu, enter the following command in the terminal:
sudo apt install apache2 -y
Step 3: Configure Firewall
By default, Ubuntu comes with a built-in firewall called ufw (Uncomplicated Firewall). To allow web traffic to your Apache server, you need to enable port 80 and 443. Enter the following commands in your terminal:
sudo ufw allow 80/tcp
sudo ufw allow 443/tcp
sudo ufw enable
Step 4: Verify Apache Installation
After installing Apache, you can verify that it is running correctly by opening your web browser and typing your server’s IP address or domain name. You should see the default Apache welcome page.
Step 5: Configure Virtual Hosts
Virtual hosts allow you to host multiple websites or web applications on a single Apache server. To configure virtual hosts, follow these steps:
- Create a directory for your website in the
/var/wwwdirectory: - Create an index.html file inside the directory:
- Add some content to the file:
- Create a virtual host file in the
/etc/apache2/sites-availabledirectory: - Add the following content to the file:
- Enable the virtual host:
- Reload Apache:
- Add domain name to hosts file:
sudo mkdir /var/www/example.com
sudo nano /var/www/example.com/index.html
<html>
<head>
<title>Example.com</title>
</head>
<body>
<h1>Welcome to Example.com!</h1>
</body>
</html>
sudo nano /etc/apache2/sites-available/example.com.conf
<VirtualHost *:80>
ServerName example.com
ServerAlias www.example.com
DocumentRoot /var/www/example.com
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
sudo a2ensite example.com.conf
sudo systemctl reload apache2
sudo nano /etc/hosts
127.0.0.1 example.com
Step 6: Enable HTTPS
Enabling HTTPS is essential for securing your website or web application and protecting user data. To enable HTTPS, follow these steps:
- Install SSL/TLS certificate:
- Create a certificate:
- Choose option 2 for redirect:
sudo apt install certbot python3-certbot-apache
sudo certbot --apache -d example.com -d www.example.com
2: Redirect - Make all requests redirect to secure HTTPS access. Choose this for new sites, or if you're confident your site works on HTTPS. You can undo this change by editing your web server's configuration.
Step 7: Secure Apache Server
By default, Apache is secure, but there are some steps you can take to harden its security:
- Limit access:
- Change permissions:
- Hide Apache version:
- Use strong ciphers:
- Restart Apache:
sudo nano /etc/apache2/apache2.conf
DirectoryIndex index.html index.php
<Directory /var/www/html>
Options Indexes FollowSymLinks
AllowOverride None
Require all granted
</Directory>
sudo chown -R www-data:www-data /var/www/html
sudo nano /etc/apache2/conf-available/security.conf
ServerTokens Prod
ServerSignature Off
sudo nano /etc/apache2/mods-available/ssl.conf
SSLCipherSuite EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH
SSLProtocol All -SSLv2 -SSLv3
SSLHonorCipherOrder On
sudo systemctl restart apache2
