What you will need

How to install the AWX dependencies

The initial factor to consider treatment of is the set up of the dependencies. Log in to your CentOS 8 server, open up a terminal window, and issue the next instructions:

sudo dnf set up epel-launch -y
sudo dnf install git gcc gcc-c++ ansible nodejs gettext product-mapper-persistent-facts lvm2 bzip2 python3-pip -y

How to install Docker and Docker Compose

We now will need to set up both of those Docker and Docker Compose. The first point to do is add the needed repository with the command:

sudo dnf config-manager --insert-repo=

After the repository is included, put in the hottest variation of Docker with the command:

sudo dnf put in docker-ce-3:18.09.1-3.el7 -y

Begin and enable the Docker motor with the commands:

sudo systemctl start out docker
sudo systemctl help docker

Add your consumer to the docker team with the command:

sudo usermod -aG docker $Person

Log out and log back in.

Install docker-compose by means of pip3 with the command:

sudo pip3 put in docker-compose

Ultimately, set python to use Python 3 with the command:

choices --set python /usr/bin/python3

How to set up AWX

Now we can at last install AWX. Clone the hottest release with the command:

git clone

Future, generate a top secret encryption critical with the command:

openssl rand -foundation64 30

Duplicate the critical that is produced to your clipboard.

Change into the freshly downloaded AWX listing with the command:

cd awx/installer

Open the AWX stock file with the command:

nano inventory

In that file, you are going to require to (at a minimal), edit the subsequent configuration possibilities. Very first, identify the line:


In that line, paste the magic formula vital you generated previously. 

Future, search for the line:


Adjust the password to a powerful, distinctive password.

Eventually, look for the line that starts with:


Modify that line to:


You can then go through the relaxation of the inventory file and edit as needed. But, the higher than alterations must consequence in a successful set up.

Build a directory for Postgres with the command:

sudo mkdir /var/lib/pgdocker

Put in AWX with the command:

sudo ansible-playbook -i inventory put in.yml

This really should choose about 5 to10 minutes to complete.

How to modify SELinux and the CentOS firewall

Right before we can obtain the AWX web-site, we will need to disable SELinux. Problem the command:

sudo nano /and so on/sysconfig/selinux

Improve the line:




Save and close the file. Restart your process so the alterations will take influence. 

The previous stage is to modify the firewall. This is accomplished with the following instructions:

sudo firewall-cmd --zone=public --add-masquerade --long lasting
sudo firewall-cmd --permanent --incorporate-support=http
sudo firewall-cmd --everlasting --incorporate-services=https
sudo firewall-cmd --reload

Last but not least, open a internet browser and level it to http://SERVER_IP (where by SERVER_IP is the IP handle of your hosting server). You will be greeted by the AWX login screen, exactly where you’ll use the admin username and the password you established in the admin_password configuration (Figure A).

Figure A


The AWX login display is completely ready for your credentials.

Once you authenticate, you are going to come across by yourself in the AWX dashboard, the place you can start performing with Ansible by this person-welcoming internet-based GUI (Figure B).

Determine B


The AWX dashboard, operating on CentOS 8, is completely ready for do the job.

Congratulations, functioning with Ansible must now be a little bit less difficult.
