Ansible AWX Part 1
2nd October 2017
This is the first part of a series on Ansible AWX. In this part we will install Ansible AWX.
Code versions used for this post
- Centos 7 - minimal 1705.02 (vagrant box)
- Python - 2.7.13
- Ansible - 2.4.0
- docker - 1.12.6
- Ansible AWX - 188.8.131.527
Note: At the time of writing AWX is not python3 compatible. You will require root/sudo privileges and PIP installed to follow this guide.
Ansible AWX Components
AWX is a web GUI based management system for Ansible. AWX is built with a microservices architecture using docker as the container runtime. Redhat provide an installer playbook as part of AWX which can build onto either an openshift cluster or a stand alone docker install. This post will use the stand alone docker method.
Pre Installation Tasks
Prior to installing AWX we will need to prepare the system.
Install required YUM packages
yum install -y epel-release yum install -y git gettext docker nodejs npm gcc-c++ bzip2
Install required PIP packages
Install the ansible and docker python libraries via PIP to get the latest stable releases.
pip2 install ansible docker
Start and enable docker service
systemctl start docker systemctl enable docker
Open firewall ports
firewall-cmd --permanent --add-service=http firewall-cmd --permanent --add-service=https firewall-cmd --reload
Set SELinux to Permissive
I dont know the necessary SELinux policies to make AWX function correctly so I am setting the policy to permissive.
To make the changes permanent set the SELINUX variable under /etc/selinux/config to permissive and reboot.
Now that pre-installation tasks are completed lets install AWX.
Clone AWX Git repo
mkdir /opt/ansible cd /opt/ansible git clone https://github.com/ansible/awx.git
Edit the inventory file
If you followed my guide on upgrading python2/3 then you will need to change the ansible_python_interpreter variable in the /opt/ansible/awx/installer/inventory file from /usr/bin/env python to /usr/local/bin/python2.7
#/opt/ansible/awx/installer/inventory # old localhost ansible_connection=local ansible_python_interpreter="/usr/bin/env python" # new localhost ansible_connection=local ansible_python_interpreter="/usr/local/bin/python2.7"
Run the install playbook
cd /opt/ansible/awx/installer/ ansible-playbook -i inventory install.yml
Login to AWX
Once the playbook is complete you can login to AWX via the web GUI.
Browse to the AWX url http://<awx-hostname-or-ip> and login with the username admin and the password is password. Note: The password can be set in the inventory file with the default_admin_password variable.
The dashboard looks like this
Note: If you see the below when browsing to the URL, wait a few minutes.
Ansible AWX is now installed and ready to be configured. In future posts I will configure AWX for use with network devices.
