Introduction
What is Apache?
First things first: let’s define what Apache is. Apache is an open-source web server software that’s been around since 1995. It’s one of the most widely used web server technologies in the world, powering almost 40% of all websites on the internet. Apache is known for its stability, security, and flexibility, making it a top choice for web developers.
Why Ubuntu 17.04?
Ubuntu 17.04 (also known as Zesty Zapus) is a Linux operating system that was released in April 2017. It’s a popular choice among developers due to its user-friendly interface and high level of customization. Ubuntu also offers a vast library of tools and applications that make web development easy and efficient.
The Benefits of Setting up Apache Server on Ubuntu
There are several benefits to setting up an Apache web server on Ubuntu. Here are just a few:

Setting Up Apache Server on Ubuntu 17.04
Step 1: Updating Your System
Before you start installing Apache, you’ll need to make sure your Ubuntu system is up-to-date. This ensures you have the latest software and security patches. To update your system, open up a terminal and enter the following commands:
sudo apt-get updatesudo apt-get upgrade
Once the update and upgrade processes have finished, reboot your system to ensure the changes take effect.
Step 2: Installing Apache
Next, you’ll need to install Apache on your system. To do this, enter the following command in your terminal:
sudo apt-get install apache2
Once the installation is complete, you can check if Apache is running by entering your server’s IP address in a web browser. You should see the Apache default page if everything is set up correctly.
Step 3: Configuring Firewall
By default, Ubuntu comes with a firewall called UFW (Uncomplicated Firewall). You’ll need to configure the firewall to allow traffic to the Apache server. To do this, enter the following commands in your terminal:
sudo ufw allow 'Apache'sudo ufw allow 'Apache Full'
The first command allows traffic to the Apache server on port 80 (HTTP), while the second command allows traffic on port 443 (HTTPS).
Step 4: Testing Your Apache Installation
To ensure your Apache installation is working correctly, you can create a test HTML page. To do this, create a new file called index.html in Apache’s default web directory:
sudo nano /var/www/html/index.html
Enter the following code into the file:
<html><head><title>Apache Test Page</title></head><body><h1>Apache is working!</h1></body></html>
Save the file and navigate to your server’s IP address in a web browser. You should see the test page you just created.
Step 5: Creating Virtual Hosts
If you plan on hosting multiple websites on your server, you’ll need to set up virtual hosts. This allows you to serve different content to different domains or subdomains. To create a virtual host, follow these steps:
- Create a new configuration file in the /etc/apache2/sites-available directory:
- Enter the following code into the file:
- Save and exit the file.
- Enable the virtual host by creating a symbolic link:
- Restart Apache to apply the changes:
sudo nano /etc/apache2/sites-available/example.com.conf
<VirtualHost *:80><ServerAdmin>admin@example.com</ServerAdmin><ServerName>example.com</ServerName><ServerAlias>www.example.com</ServerAlias><DocumentRoot>/var/www/example.com/public_html</DocumentRoot><Directory><Options>FollowSymLinks</Options><AllowOverride>All</AllowOverride><Require>all granted</Require></Directory><FilesMatch> "\\.php$"SetHandler "proxy:unix:/run/php/php7.0-fpm.sock|fcgi://localhost/"</FilesMatch><ErrorLog>/var/log/apache2/example.com_error.log</ErrorLog><CustomLog>/var/log/apache2/example.com_access.log combined</CustomLog></VirtualHost>
sudo ln -s /etc/apache2/sites-available/example.com.conf /etc/apache2/sites-enabled/
sudo systemctl restart apache2
Step 6: Configuring SSL
If you want to secure your websites with SSL (Secure Sockets Layer), you’ll need to configure SSL on your server. Follow these steps to set up SSL:
- Install the SSL module:
- Create a new SSL certificate:
- Configure Apache to use the new SSL certificate:
- Add the following lines to the file:
- Enable the SSL virtual host:
- Restart Apache to apply the changes:
sudo apt-get install libapache2-mod-ssl
sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/ssl/private/apache-selfsigned.key -out /etc/ssl/certs/apache-selfsigned.crt
sudo nano /etc/apache2/sites-available/default-ssl.conf
<IfModule mod_ssl.c><VirtualHost _default_:443>ServerAdmin webmaster@localhostServerName example.comDocumentRoot /var/www/htmlErrorLog ${APACHE_LOG_DIR}/error.logCustomLog ${APACHE_LOG_DIR}/access.log combinedSSLEngine onSSLCertificateFile /etc/ssl/certs/apache-selfsigned.crtSSLCertificateKeyFile /etc/ssl/private/apache-selfsigned.key<FilesMatch> "\\.php$"SetHandler "proxy:unix:/run/php/php7.0-fpm.sock|fcgi://localhost/"</FilesMatch><Directory /var/www/html>Options Indexes FollowSymLinksAllowOverride AllRequire all granted</Directory></VirtualHost></IfModule>
sudo a2ensite default-ssl.conf
sudo systemctl restart apache2
Step 7: Fine-Tuning Apache
Now that your Apache server is up and running, you might want to fine-tune its settings to optimize performance. Here are a few things you can do:
- Disable unnecessary modules: Apache comes with several modules that you may not need. Disable any modules that you don’t use to save resources.
- Optimize caching: Apache has built-in caching features that can improve performance. Use caching to speed up your websites.
- Tune your settings: Apache’s configuration file (apache2.conf) contains several settings that you can tweak to improve performance. Experiment with different settings to find what works best for your server.
