# Insall EPEL repository
yum -y install epel-release

# Disable firewall and SELinux
systemctl disable firewalld
systemctl stop firewalld
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
setenforce 0
reboot

# Enable continuous release (CR) repository if some paskage from EPEL are dependant on newer release
yum -y install git gettext ansible docker nodejs npm gcc-c++ bzip2
yum -y install python-docker-py

#  Start and enable docker service
systemctl start docker
systemctl enable docker

# Clone repository and deploy (it will take about 20 minutes)
git clone https://github.com/ansible/awx.git
cd awx/installer/
ansible-playbook -i inventory install.yml

# Monitor migrations status (it will take about 10 minutes)
docker logs -f awx_task
Now you can access AWX web server http://my-awx.example.com.

The default administrator username is admin, and the password is password.

yum -y install docker-python

Currently deploying on CentOS 7 1810 fully up to date.

At line 29, it gets to a point that gives me an error about conflicting docker SDK libraries and lack of compose library. Even don-rumata suggestion didn't solve it.
I solved it by removing everything I had installed related to docker with python (python-docker-py or docker-python) and replacing line 20 command with these:

yum -y install python-pip
pip install docker docker-compose

i 'd this error after complete install awx :
curl: (7) Failed to connect to My @ip port 80: Connection refused
and i resolv it with these commands:

pip uninstall docker
pip uninstall docker-py
pip uninstall docker-compose
pip install docker-compose==1.9.0

i 'd this error after complete install awx :
curl: (7) Failed to connect to My @ip port 80: Connection refused
and i resolv it with these commands:

pip uninstall docker
pip uninstall docker-py
pip uninstall docker-compose
pip install docker-compose==1.9.0

Thank you!!

could you please help me with this error?

Seems Python3 is not installed

Hi Dasgoll

Thanks for your valuable input, I have installed Python 3 with SCL to start the download and installation of ansible. now I see the containers in Docker and load the Ansible web page. but what happens is that it stays loading and never finishes updating. analyzing the log I see the following. I appreciate you can help me.

-Log:
