[AWX] How to install AWX 11.2.0 by Python3 and Docker-Compose

  • OS Version: RHEL 7.8
  • Ansible Version: 2.9.9 (both yum and pip version)
  • Docker CE Version: 19.03.9
  • Docker-Compose Version: 1.25.5
  • Python2 Version: 2.7.5
  • Python3 Version: 3.6.8
  • Libselinux-python3 Version: 2.5-15
  • PostgreSQL Container Version: 10
  • PostgreSQL Version: 11.5-1PGDG
  • AWX Container Version: 11.2.0
  • Redis Contanier Version: 6.0.3
  • Memcached Container Version: 1.6.6

Preparing

Notice

Please note that AWX is a new application for last few years, so the version change very quickly and this will let people need to be carefully on version selection when you want to install it.

Environment

My simulation environment:

Fresh install OS on RHEL 7.5 and upgrade to 7.8, so there will have python2 install on it. This will make your AWX installation more tricky, therefore it’s better to create a virtualenv for python3 or fresh install your OS by RHEL 8.

Based on this experience, RHEL 7.7 won’t be successful to install AWX because of the
“`libselinux-python“` version. On RHEL 7.7 the repo of yum only have python2 version **( I use python3 to install AWX )** and this bug is been solve on **RHEL 7.8** or later version.

According to Redhat official document: RHEA-2020:1165 – Product Enhancement Advisory

If you use python2 to intall AWX then this problem would not bother you.

About
“`install.yml“` file there are some module name “`docker_compose“`, if your ansible is early than 2.8 then you have to change the module name to “`docker_service“`, otherise the install playbook won’t work.

Redis vs RabbitMQ

After version 10.0.0 AWX replace RabbitMQ to Redis, so to prevent some Redis warning, we can modify some config.

## WARNING overcommit_memory is set to 0
# Add vm.overcommit_memory=1 to sysctl.conf
vim /etc/sysctl.conf
vm.overcommit_memory=1


## WARNING: The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128.
# Add net.core.somaxconn=1024 to sysctl.conf
# But this config not working, still investigate it.
vim /etc/sysctl.conf
net.core.somaxconn=1024

## WARNING you have Transparent Huge Pages (THP) support enabled in your kernel
# Add "echo never > /sys/kernel/mm/transparent_hugepage/enabled" to your /etc/rc.local.
vim /etc/rc.local
echo never > /sys/kernel/mm/transparent_hugepage/enabled

# or just run
echo never > /sys/kernel/mm/transparent_hugepage/enabled

If THP can not disable by above method then you will have to modify
“`grub“` config file. Please be noticed changing any config in grub file by wrong method will cause system crashed, so please modify it carefully.

# Add transparent_hugepage=never to the file
vim /etc/default/grub

GRUB_TIMEOUT=5
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="nomodeset crashkernel=auto rd.lvm.lv=vg_os/lv_root rd.lvm.lv=vg_os/lv_swap rhgb quiet transparent_hugepage=never"
GRUB_DISABLE_RECOVERY="true"

# On BIOS-based machines (In this case, I'm using esxi to run my vm, so I choose this option to execute)
grub2-mkconfig -o /boot/grub2/grub.cfg

# On UEFI-based machines
grub2-mkconfig -o /boot/efi/EFI/redhat/grub.cfg

# restart VM

# Check validation.
cat /proc/cmdline

Official System Packages (YUM) vs Python Install Packages (PIP)

There are some packages will conflict for each other or confuse user’s usages, so when you want to install AWX you will need to deal with this selection and make your own choice, because everyone’s architecture are different.

  • Yum: ansible, libselinux-python, pyOpenSSL (in python2?)
  • Pip: ansible, selinux, pyOpenSSL

You probably will get some error during your installation, please check the version of the above software package you are using. VirtualEnv will be a better way to avoid the packages problem, but still this is depends on your situation.

Simulation 1 – All in one

Fresh install AWX 11.2.0 without modify any config even password.

Try to simple the install process so would not have any external services.

Preinstall

Package list:

Pip: ansible, selinux, pyOpenSSL

System Packages

yum -y install yum-utils git gcc gcc-c++ nodejs gettext device-mapper-persistent-data lvm2 bzip2 python3-pip vim nano libselinux-python3
yum remove pyOpenSSL
# yum remove ansible --> This depends on your situation, I don't delete it in my simulation 1.
# If you don't remove it or even you remove it, you probably still have to solve the /bin/ansible problem.
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
yum list docker-ce --showduplicates | sort -r
yum install docker-ce.x86_64 3:19.03.9-3
systemctl start docker && systemctl enable docker && systemctl status docker

Pip Ansible

You can make python3 pip install ansible for your major version, but you will have to remove the system’s ansible.

# remove official pacakges' ansible
yum erase ansible

# reboot your VM
reboot

# Python3's pip install
python3 -m pip install ansible

# Check ansible version and python version
ansible --version

# If you can not execute ansible, then you need give it execution priviledge
chmod +x /usr/local/lib/python3.6/site-packages/ansible

# Install pip packages
python -m pip install wheel pyyaml urllib3 pyvmomi pyVim jmespath docker docker-compose awscli boto3 oauthlib purestorage ntlm-auth azure-common azure-keyvault azure-nspkg "pywinrm>=0.3.0" pywinrm[credssp] f5-sdk bigsuds selinux
python -m pip install client
python -m pip install suds

But this is very annoying, so Python Virtualenv will be more easy way to do it.

Virtualenv Method

cd /root
python3 -m pip install pip -U
python3 -m pip install setuptools -U
python3 -m pip install virtualenv
/usr/local/bin/virtualenv ansible29
source /root/ansible29/bin/activate
python -m pip install wheel pyyaml urllib3 pyvmomi pyVim jmespath ansible docker docker-compose awscli boto3 oauthlib purestorage ntlm-auth azure-common azure-keyvault azure-nspkg "pywinrm>=0.3.0" pywinrm[credssp] f5-sdk bigsuds
python -m pip install client
python -m pip install suds

Install AWX

Generate Secret Key (If you need)

openssl rand -base64 30

kf/30tq8S1ESHxDus3U+94RDUKAiIPWdqpx21biT

Git Source Code

cd /root
git clone https://github.com/ansible/awx.git
cd awx
git checkout -b 11.2.0 11.2.0
cd installer/

# Change config if you need, we dont show this part, because we don't change anything in config file.
vim inventory

chmod +x /root/ansible29/bin/*
/root/ansible29/bin/ansible-playbook -i inventory install.yml -vvvv
docker ps -a

You should find out the website goes up.

Bug resolve

Web GUI keep showing upgrading (migrations_notran).

# From Github's Solution. Restart the container
cd /root/.awx/awxcompose/
docker-compose stop && docker-compose rm
docker-compose up -d

This method works for me.

Simulation 2 – Using External PostgreSQL DB

  • PostgreSQL Version: 11.5-1PGDG

Fresh install AWX 11.2.0 and change PostgreSQL to external node, using external nginx to proxy AWX web and other config.

Install Bug Resolving

### Beforce running install check your ansible's python
ansible --version

### If you see your python still show python 2.7.5, this means the /bin/ansible still point to your yum version not your pip version.

### Here are some method I try to used to solve this problem.
## Method 1: Use the command below, not to replace the original link. (Not Working)
# Failed by
# "msg": "Aborting, target uses selinux but python bindings (libselinux-python) aren't installed!"
ll /var/lib/awx/custom-venv/python36/bin/
chmod +x /var/lib/awx/custom-venv/python36/bin/*
python $(which ansible) --version
python $(which ansible-playbook) -i inventory install.yml -vvv

## Method 2: Remove system's ansible (Not Working)
# Failed by
# "msg": "Aborting, target uses selinux but python bindings (libselinux-python) aren't installed!"
yum remove ansible
/var/lib/awx/custom-venv/python36/bin/ansible-playbook -i inventory install.yml -vvv
python $(which ansible-playbook) -i inventory install.yml -vvv

## Method 3: Recreate Virtualenv with --system-site-packages (Working)
deactivate
rm -rf /var/lib/awx/custom-venv/python36/
cd /var/lib/awx/custom-venv
virtualenv --system-site-packages python36

source /var/lib/awx/custom-venv/python36/bin/activate
python -m pip install wheel pyyaml urllib3 pyvmomi pyVim jmespath ansible docker docker-compose awscli boto3 oauthlib purestorage ntlm-auth azure-common azure-keyvault azure-nspkg "pywinrm>=0.3.0" pywinrm[credssp] f5-sdk bigsuds
python -m pip install client
python -m pip install suds
chmod +x /var/lib/awx/custom-venv/python36/bin/*
cd /root/awx/installer/

# Run install
ansible-playbook -i inventory install.yml -vvv
docker ps -a

# Bug
# You probably will get some error for example, I saw my Web GUI shows AWX upgrading but never stop.....(migrations_notran problem) then I restart the container services and Web works fine.
docker-compose stop && docker-compose rm
docker-compose up -d
docker-compose restart

## Method 4: I think there must have different solution, but I don't have much time to try it all.

Using Extend Nginx to proxy

We can use docker volume to mount nginx conf folder to local VM, but if you don’t want to do that way. You can use local VM’s nginx to proxy your request.

So When your are install AWX, you have to change the host_port to other port number.

# New port number
host_port=8080
host_port_ssl=8443

Then create your SSL key to apply for SSL Certification License.

# Create CSR
openssl genrsa -out www.xxxxxx.com.key 4096
openssl rsa -in www.xxxxxx.com.key -out www.xxxxxx.com.key
openssl req -new -key www.xxxxxx.com.key -out www.xxxxxx.com.csr

Apply your SSL certificate and put the CRT file to the place you want.

Then install nginx.

yum install -y nginx
vim /etc/nginx/nginx.conf

Config file.

Nginx Web can not show anything

If you don see anything come from nginx and when you check the docker log see this log blew:

docker logs awx_web

This error message shows that your nginx can not find out the external PostgreSQL DB, so I reinstall awx and change pg_hostname to different combination such as change to IP, FQDN(not shortname), edit
“`/etc/hosts“` file, using awx_alternate_dns_servers but still get the same error message.

I even find article that shows you have to change the docker file because of the
“`base.py“`, but I try not to modify official file.

Then I try to login to awx_web to investigate why hostname can not used. I discover that my old AWX have gateway, but my new AWX do not have.

docker network ls
docker network inspect bridge

docker network inspect bridge

After above command my docker gateway shows up……….weired.
