In this post I want to go over adding AWX to the ansible server.
What is AWX and how does it help you?
AWX is an add on to the basic community edition, which allows you better control project use of ansible in an IT environment. You can find more information here.
If you have already installed Ansible community edition, great, else these steps are covered here.
Additionally some other bits and pieces are required.
If you followed the guide above then the only things you need are these:
Install these by running this command:
sudo dnf install git gcc gcc-c++ nodejs bzip2 -y
Once installed we need to add a repo for docker-ce.
sudo dnf config-manager --add-repo=https://download.docker.com/linux/centos/docker-ce.repo
and then we need to install docker ce
sudo dnf install docker-ce -y
This leaves us with some more packages installed, run docker –version to verify that docker is installed and run the following command to start and enable docker.
sudo systemctl start docker && systemctl enable docker
Now we install docker-compose and check the version:
pip3 install docker-compose docker-compose --version
Use the following command to use python version 3. (You should anyway since 2.x is unsupported now).
sudo alternatives --set python /usr/bin/python3
Thats the prerequisites completed.
Now to install AWX itself we need to get it form the github repo.
To do this run the following command:
git clone https://github.com/ansible/awx.git
Afterwards we need to generate a secret, which you should keep handy for later:
openssl rand -base64 30
use your favourite editor to edit the following file: awx/installer/inventory
Change the following lines in the [all:vars] section (Some may already be there, I have highlighted the ones I found in bold/italic, so only the non-bold ones needs to be adapted, replace the secret with the secret you created above):
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=cfePcEoYW5w8MIS5qY9CUraOwysaO+d6jS3u4TmD awx_official=true awx_alternate_dns_servers="126.96.36.199,188.8.131.52" project_data_dir=/var/lib/awx/projects
Once these things have been changed, then create the dir for the postgres file dir.
Aand…. that is it we can install awx by running the following playbook from the installation folder (home/username/awx/installer).
sudo ansible-playbook -i inventory install.yml
Wait while your screen is flooded with tasks.
At the end you should have a screen like this (at least without failed, I hope):
Now just the last post steps:
Change selinux to “permissive” (please don’t disable it, it is there for a reason…)
You can do that by editing the /etc/sysconfig/selinux file
sudo vi /etc/sysconfig/selinux
Change the mode from enforcing to permissive.
Save the file and then we need to open a couple of firewall rules, and reload the service.:
sudo firewall-cmd --zone=public --add-masquerade --permanent sudo firewall-cmd --permanent --add-service=http sudo firewall-cmd --permanent --add-service=https sudo firewall-cmd --reload
Now check if you can access the AWX logon page via your web-browser, note http://fqdn:
Use the username and password you set in the config file to log in.
You should see a screen like this:
Thats it. AWX plugin has been installed. Next time more about how to use AWX.
