ansible-awx 安装

开始直接用红帽的试用版 ansible-tower，可以直接使用红帽的安装源
后来正版化，以及方便部署，部署ansible-awx 到openshift的社区版上
后来开发有其他的需求，所在机房没有k8s的集群，所以找到了这个社区源，备忘

yum -y install rabbitmq-server

yum install -y rh-postgresql10 memcached

yum -y install rh-python36
yum -y install --disablerepo='*' --enablerepo='mrmeee-ansible-awx, base' -x -debuginfo rh-python36
scl enable rh-postgresql10 "postgresql-setup initdb"

systemctl enable rabbitmq-server
systemctl start rabbitmq-server

• Start services: Postgresql Database

  systemctl start rh-postgresql10-postgresql.service
  systemctl enable rh-postgresql10-postgresql.service
  

• Start services: Memcached

systemctl enable memcached
systemctl start memcached

• Create Postgres user and DB:

  scl enable rh-postgresql10 "su postgres -c \"createuser -S awx\""
  scl enable rh-postgresql10 "su postgres -c \"createdb -O awx awx\""
  

Configure AWX

• Import Database data:

sudo -u awx scl enable rh-python36 rh-postgresql10 "awx-manage migrate"

• Initial configuration of AWX

echo "from django.contrib.auth.models import User; User.objects.create_superuser('admin', 'root@localhost', 'password')" | sudo -u awx scl enable rh-python36 rh-postgresql10 "awx-manage shell"

sudo -u awx scl enable rh-python36 rh-postgresql10 "awx-manage create_preload_data"
sudo -u awx scl enable rh-python36 rh-postgresql10 "awx-manage provision_instance --hostname=$(hostname)"
sudo -u awx scl enable rh-python36 rh-postgresql10 "awx-manage register_queue --queuename=tower --hostnames=$(hostname)"

Install and Configure Web Server Proxy

• Install NGINX as proxy:

yum -y install nginx
wget -O /etc/nginx/nginx.conf https://raw.githubusercontent.com/MrMEEE/awx-build/master/nginx.conf
systemctl enable nginx
systemctl start nginx

Start and Enable AWX

• Start Services

systemctl start awx-cbreceiver
systemctl start awx-dispatcher
systemctl start awx-channels-worker
systemctl start awx-daphne
systemctl start awx-web

• Enable Services

systemctl enable awx-cbreceiver
systemctl enable awx-dispatcher
systemctl enable awx-channels-worker
systemctl enable awx-daphne
systemctl enable awx-web

yum install -y ansible-awx

找了半天文档，发现是一个bug

This is a bug in Ansible Tower 3.1.x and 3.2 backup and restore that will be addressed in Ansible Tower 3.2.2.
The current resolution is to rerun the setup.sh after you do the restore. That will reconfigure the rabbitmq.py in the current installation.

Root cause is while doing a backup on a Tower instance, it is not excluding rabbitmq.py and hence while doing a restore on a different Ansible Tower instance it restores the original rabbitmq.py, which breaks the rabbitmq clustering.

用下面的命令修复

 sudo -u awx scl enable rh-python36 rh-postgresql10 "awx-manage create_preload_data"
 sudo -u awx scl enable rh-python36 rh-postgresql10 "awx-manage provision_instance --hostname=$(hostname)"
 sudo -u awx scl enable rh-python36 rh-postgresql10 "awx-manage register_queue --queuename=tower --hostnames=$(hostname)"
  
 systemctl restart  awx-cbreceiver
 systemctl restart  awx-dispatcher
 systemctl restart  awx-channels-worker
 systemctl restart  awx-daphne
 systemctl restart  awx-web
