How to Install and Configure Ansible AWX on Rocky Linux 8.3 and CentOS 8

How to Install and Configure Ansible AWX on Rocky Linux 8.3 and CentOS 8

AWX stands for “Ansible Web eXecutable” is a free and open-source project that allows you to easily manage and control Ansible projects. AWX provides a web-based user interface, a powerful REST API and allows you to manage or sync inventory with other cloud sources, control access, and integrate with LDAP.

In this tutorial, we will show you how to install AWX Ansible AWX with Docker on Rocky Linux 8.3 and CentOS 8.


  • Rocky Linux 8.3 or CentOS 8 server with a minimum of 4 GB RAM.
  • Log in as root or user with privileges sudo

Before Starting

Add the EPEL Repository on the system with the following command:

dnf install epel-release -y 

Next, you will need to install some additional packages that are required to run AWX on the system. You can install them all with the following command:

dnf install git gcc gcc-c++ ansible nodejs gettext device-mapper-persistent-data lvm2 bzip2 python3-pip -y 

Once all packages have been installed, you can move on to the next step.

Install Docker dan Docker Compose

Next, we need to install Docker to run AWX inside a Docker container. By default, the latest version of Docker is not available in the default CentOS 8 repositories.So you need to add the Docker repository on your system. You can add the Docker repository with the following command:

dnf config-manager --add-repo= 

Once added, install the latest stable version of Docker with the following command:

dnf install docker-ce-3:18.09.1-3.el7 -y 

Once Docker is installed, check which version of Docker is installed with the following command:

docker --version 

You should get something like this:

Docker version 19.03.7, build 7141c199a2

Next, start the Docker service and enable it to start after the system reboots with the following command:

systemctl start docker
 systemctl enable docker 

You can verify the status of the Docker service with the following command:

systemctl status docker 

You should get something like this:

? docker.service - Docker Application Container Engine
   Loaded: loaded (/usr/lib/systemd/system/docker.service; disabled; vendor preset: disabled)
   Active: active (running) since Wed 2020-03-11 02:36:04 EDT; 23min ago

Next, install Docker compose using the following command:

pip3 install docker-compose 

Once installed, verify the Docker compose version using the following command:

docker-compose --version 

You will see the following output:

docker-compose version 1.25.4, build unknown

Finally, run the following command to set the python command to use python 3:

alternatives --set python /usr/bin/python3

Install CentOS 8 Ansible AWX

First, download the latest version of Ansible AWX from the Git Hub repository using the following command:

git clone 

Next, create a secret key to encrypt the inventory file with the following command:

openssl rand -base64 30 

You will get the following output:

R + kbcDEUS8DlAftAbtWafVfLZ0lUy + Paqo3fEtep

Note : Write down the secret key that appears by copying and pasting it into a text editor, because you have to paste it in the inventory file.

Next, change to the directory awx/ installer / and edit the inventory file with a text editor nano:

cd awx/installer/
 nano inventory 

Change the following lines:

[all: vars] 
 dockerhub_base = ansible 
 awx_task_hostname = awx 
 awx_web_hostname = awxweb 
 postgres_data_dir = "/ var / lib / pgdocker" 
 host_port = 80 
 host_port_ssl = 443 
 docker_compose_dir = "~ / .awx / awxcompose" 
 pg_username = awx 
 pg_password = awxpass 
 pg_database = awx 
 pg_port = 5432 
 pg_admin_password = password 
 rabbitmq_password = awxpass 
 rabbitmq_erlang_cookie = cookiemonster 
 admin_user = admin 
 admin_password = password 
 create_preload_data = True 
 secret_key = R + kbcDEUS8DlAftAbtWafVfLZ0lUy + Paqo3fEtep 
 awx_official = true 
 awx_alternate_dns_servers = "," 
 project_data_dir = / var / lib / awx / projects 

Save and close the file when you are done. Then, Create Directory for Postgres:

mkdir /var/lib/pgdocker 

Finally, run the following command to install AWX:

ansible-playbook -i inventory install.yml 

After the installation has finished successfully, you should get the following output:

The command above will create and start all the necessary Docker containers for AWX. You can verify a running container with the following command:

docker ps 

You will see the following output:

Configure SELinux and Firewall

By default, SELinux is enabled on CentOS 8. It is recommended to disable it to work AWX in Docker environment. You can disable it by editing the following file:

nano /etc/sysconfig/selinux 

Find the following line:


And, replace it with the following line:


Save and close the file when you are done. Then, restart the system to implement the changes. Next, you need to allow http and https services through firewalld. You can allow them with the following command:

firewall-cmd --zone=public --add-masquerade --permanent
 firewall-cmd --permanent --add-service=http
 firewall-cmd --permanent --add-service=https 

Next, restart the firewalld service to apply the changes:

firewall-cmd --reload 

AWX Web Interface Access

Now, open your web browser and type in the URL http: // domain_ or_server-ip. You will be directed to the AWX login page:


Provide your admin username and password which you have set in the inventory file and click the button SIGN IN . You will see the AWX default dashboard on the following page:



Congratulations! You have successfully installed AWX with Docker on Rocky linux 8.3 and CentOS 8. Now you can easily manage and control your Ansible projects using the AWX web interface.
