Ansible AWX es la versión OpenSource de ansible tower. AWX proporciona una interfaz de usuario basada en la web, una API REST y un motor de tareas construido sobre Ansible. Es el proyecto upstream de Tower, un derivado comercial de AWX.
En este tutorial, le mostraré cómo instalar y configurar AWX mediante Docker.
Usaré 3 servidores con instalación mínima de centos 7 y SELinux en modo permisivo.
- 192.168.1.25 Servidor AWX
- 192.168.1.21 cliente1
- 192.168.1.22 cliente2
Requisitos del sistema para el servidor AWX
- Al menos 4 GB de memoria.
- Al menos 2 núcleos de CPU.
- Al menos 20 GB de espacio.
- Ejecutar Docker, Openshift o Kubernetes.
Compruebe la configuración de SELinux.
sestatus
Resultado:
[[email protected] ~]# sestatus SELinux status: enabled SELinuxfs mount: /sys/fs/selinux SELinux root directory: /etc/selinux Loaded policy name: targeted Current mode: permissive Mode from config file: permissive Policy MLS status: enabled Policy deny_unknown status: allowed Max kernel policy version: 28 [[email protected] ~]#
Desactivar cortafuegos.
[[email protected] installer]# systemctl stop firewalld [[email protected] installer]# systemctl disable firewalld Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service. Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service. [[email protected] installer]#
Agregar las entradas de host en /etc/hosts
[[email protected] ~]# cat /etc/hosts 192.168.1.25 awx.sunil.cc awx 192.168.1.21 client1.sunil.cc client1 192.168.1.22 client2.sunil.cc client2 [[email protected] ~]#
Habilitar epel repositorio.
[[email protected] ~]# yum install -y epel-release
Instale los paquetes.
[[email protected] ~]# yum install -y yum-utils device-mapper-persistent-data lvm2 ansible git python-devel python-pip python-docker-py vim-enhanced
Configure el repositorio estable docker ce.
[[email protected] ~]# yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
Instalando ventana acoplable.
[[email protected] ~]# yum install docker-ce -y
Inicie el servicio docker.
[[email protected] ~]# systemctl start docker
Habilitar el servicio docker.
[[email protected] ~]# systemctl enable docker
Clonar el repositorio AWX.
[[email protected] ~]# git clone https://github.com/ansible/awx.git [[email protected] ~]# cd awx/ [[email protected] awx]# git clone https://github.com/ansible/awx-logos.git [[email protected] awx]# pwd /root/awx [[email protected] awx]#
Vaya al directorio del instalador dentro de /root/awx.
[[email protected] awx]# cd installer/
Edite los siguientes parámetros en el inventario.
[[email protected] awx]# vim inventory postgres_data_dir=/var/lib/pgdocker awx_official=true awx_alternate_dns_servers="4.2.2.1,4.2.2.2" project_data_dir=/var/lib/awx/projects
Su configuración debería verse así.
[[email protected] installer]# cat inventory |grep -v "#" localhost ansible_connection=local ansible_python_interpreter="/usr/bin/env python" [all:vars] dockerhub_base=ansible dockerhub_version=latest rabbitmq_version=3.6.14 awx_secret_key=awxsecret postgres_data_dir=/var/lib/pgdocker host_port=80 docker_compose_dir=/var/lib/awx pg_username=awx pg_password=awxpass pg_database=awx pg_port=5432 awx_official=true awx_alternate_dns_servers="4.2.2.1,4.2.2.2" project_data_dir=/var/lib/awx/projects [[email protected] installer]#
Ahora implementando AWX a través de Docker.
[[email protected] installer]# ansible-playbook -i inventory install.yml -vv
Esto llevará un tiempo dependiendo de la configuración del servidor.
Para verificar la implementación de ansible play para AWX, ejecute el siguiente comando.

AWX está listo y se puede acceder desde el navegador.
el nombre de usuario es "admin" y la contraseña es "contraseña".
Configure el inicio de sesión sin contraseña desde el servidor AWX
Cree un usuario en los 3 hosts. Siga los pasos a continuación en los 3 servidores.
