Using your Oracle Free Cloud to host your Wordpress website

project42 profile image Project-42 ・5 min read

One of the advantage of the Oracle Cloud Free Tier is that you can run up to 2 VMs on it.

This allows you to even have some "hosting" for some things like a web server or Rocket chat service

So, just to give you an example about what is possible, lets try installing WordPress in the quickest way possible

Start Creating a new VM and select your image Name before pressing the "Change Image" button

Change Image

For this example, we are going to use Centos7 image, which is one of the free images we have access to


Press "Show Shape, Network and Storage Options" and go to the bottom to make sure the system will ha a public IP

Show Shape

Public IP

Add your public SSH key and hit "Create"


Once the system is started, you should be able to see your "Public IP Address"

Public IP

Now, open a terminal and connect to the system using that IP:

P42@laptop:~ # ssh opc@xxx.xxx.xxx.130
The authenticity of host 'p42_vm (xxx.xxx.xxx.130)' can't be established.
ECDSA key fingerprint is SHA256:zWErGTOV9yEf.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'p42_vm,xxx.xxx.xxx.130' (ECDSA) to the list of known hosts.

[root@p42-vm ~]#

First think we need is to get docker installed and started:

[root@p42-vm ~]# curl -fsSL https://get.docker.com -o get-docker.sh
[root@p42-vm ~]# sh get-docker.sh
# Executing docker install script, commit: 442e66405c304fa92af8aadaa1d9b31bf4b0ad94

If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:

  sudo usermod -aG docker your-user

Remember that you will have to log out and back in for this to take effect!

WARNING: Adding a user to the "docker" group will grant the ability to run
         containers which can be used to obtain root privileges on the
         docker host.
         Refer to https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface
         for more information.
[root@p42-vm ~]#

[root@p42-vm ~]# systemctl enable docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.
[root@p42-vm ~]# systemctl start docker
[root@p42-vm ~]#

Now that we have docker, we just need to get the dockers for the Wordpress components installed.
Create a directory for this project:

[root@p42-vm ~]# mkdir ~/wordpress && cd ~/wordpress
[root@p42-vm wordpress]#

Lets start with the Database for wordpress .
On this step we are installing mariadb engine, setting the root password to 'welcome1' and creating the DB 'wordpressdb'
(remember to use better passwords! :P)

[root@p42-vm wordpress]# docker run -e MYSQL_ROOT_PASSWORD=welcome1 -e 
MYSQL_DATABASE=wordpress --name wordpressdb -v 
"$PWD/database":/var/lib/mysql -d mariadb:latest

Status: Downloaded newer image for mariadb:latest
[root@p42-vm wordpress]#

Create the local folder where the webserver will keep the files:

[root@p42-vm wordpress]# mkdir -p /var/www/html

And now lets get wordpress build installed.
Remember to use the DB name we set on previous step as well as the password.
We are also setting '/var/www/html' to keep the necessary webserver files
Additionally, we are setting docker to set the traffic coming to the host from port 80 to the container 80, since that is the default port the build has enabled:

[root@p42-vm wordpress]# docker run -e WORDPRESS_DB_PASSWORD=welcome1 
--name wordpress --link wordpressdb:mysql -p 80:80 -v 
"$PWD/html":/var/www/html -d wordpress

[root@p42-vm wordpress]#

Remember to open port 80 of the host:

[root@p42-vm wordpress]# firewall-cmd --zone=public --permanent --add-port=80/tcp
[root@p42-vm wordpress]# firewall-cmd --reload
[root@p42-vm wordpress]#

[root@p42-vm ~]# docker ps
CONTAINER ID    IMAGE               COMMAND                  CREATED             STATUS              PORTS                NAMES

[root@p42-vm ~]#

Now, go to the Oracle Cloud Gui and open the port 80 so we can connect to the system using that port.

From the Instance Details, click in "Virtual Cloud Network" → "Security Lists" → "Default Security list ...."



Here, we can now add new Rule for port 80, so system will allow connections




and Voila! free hosting ready :)

Wordpress Install

This is just an example of what you can do with your Oracle Cloud Free Subscription
