Install Apache on Ubuntu – Google Cloud

Install Apache on Ubuntu – Google Cloud. Apache is the most widely used HTTP web server which provides dynamic loading modules, easily integrating with other applications.

Not using Ubuntu 18.04 LTS? Choose a different OS:

This guide helps you to install Apache on Ubuntu 18.04 on Google Compute Engine.

Prerequisites

1. Your Compute Engine Instance running.
2. For setting up Compute Engine, see the Setting up Compute Engine Instance.
3. Ubuntu server setup on Google Cloud.

Install Apache

Let’s start by updating the local package index with the following command.

sudo apt update
sudo apt upgrade

Install Apache 2 package from the Ubuntu repository.

sudo apt install apache2

This will install apache2 and all required dependencies.

Setup Firewall

Now you can set up Uncomplicated Firewall (UFW) with Apache to allow public access on default web ports for HTTP and HTTPS

sudo ufw app list

You will see all listed applications.

Output
Available applications:
   Apache
   Apache Full
   Apache Secure
   OpenSSH

• Apache: This profile opens port 80 (normal, unencrypted web traffic)
• Apache Full: This profile opens both port 80 (normal, unencrypted web traffic) and port 443 (TLS/SSL encrypted traffic)
• Apache Secure: This profile opens only port 443 (TLS/SSL encrypted traffic)
• OpenSSH: This profile opens port 22 for SSH access.

If you are not going to use SSL you need to enable only the Apache profile.

Now we will enable Apache Full.

sudo ufw allow 'Apache Full'

With this command you can view the status of UFW.

sudo ufw status

You will see the output as follows.

Output
Status: active
 To                         Action      From
 --                         ------      ----
 Apache Full                ALLOW       Anywhere                  
 OpenSSH                    ALLOW       Anywhere                  
 Apache Full (v6)           ALLOW       Anywhere (v6)             
 OpenSSH (v6)               ALLOW       Anywhere (v6)

Check Apache Installation

Once Apache is installed is is started automatically and already be up and running.

Every process in Apache is managed with the systemctl command. Check the status of Apache with the following command.

sudo systemctl status apache2

Output
● apache2.service - The Apache HTTP Server
    Loaded: loaded (/lib/systemd/system/apache2.service; enabled; vendor preset: enabled)
   Drop-In: /lib/systemd/system/apache2.service.d
            └─apache2-systemd.conf
    Active: active (running) since Tue 2019-01-29 03:59:34 UTC; 5min ago

    CGroup: /system.slice/apache2.service
            ├─10617 /usr/sbin/apache2 -k start
            ├─10619 /usr/sbin/apache2 -k start
            └─10620 /usr/sbin/apache2 -k start
 Jan 29 03:59:34 apache systemd[1]: Starting The Apache HTTP Server…
 Jan 29 03:59:34 apache systemd[1]: Started The Apache HTTP Server.

Now visit the External IP address of your VM instance, you will see the default Apache welcome page.
