Ansible AWX è la versione OpenSource di ansible tower. AWX fornisce un'interfaccia utente basata sul Web, un'API REST e un motore di attività basato su Ansible. È il progetto a monte di Tower, un derivato commerciale di AWX.
In questo tutorial, ti mostrerò come installare e configurare AWX utilizzando Docker.
Userò 3 server con centos 7 installazione minima e SELinux in modalità permissiva.
- Server 192.168.1.25 AWX
- 192.168.1.21 client1
- 192.168.1.22 client2
Requisiti di sistema per AWX Server
- Almeno 4 GB di memoria.
- Almeno 2 core di CPU.
- Almeno 20 GB di spazio.
- Esecuzione di Docker, Openshift o Kubernetes.
Controlla la configurazione di SELinux.
sestatus
Risultato:
[[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] ~]#
Disabilita firewalld.
[[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]#
Aggiunta delle voci host in /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] ~]#
Abilita repository epel.
[[email protected] ~]# yum install -y epel-release
Installa i pacchetti.
[[email protected] ~]# yum install -y yum-utils device-mapper-persistent-data lvm2 ansible git python-devel python-pip python-docker-py vim-enhanced
Configura il repository stabile della finestra mobile.
[[email protected] ~]# yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
Installazione della finestra mobile.
[[email protected] ~]# yum install docker-ce -y
Avvia il servizio Docker.
[[email protected] ~]# systemctl start docker
Abilita il servizio Docker.
[[email protected] ~]# systemctl enable docker
Clonazione del repository 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]#
Vai nella directory di installazione all'interno di /root/awx.
[[email protected] awx]# cd installer/
Modifica i seguenti parametri nell'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
La tua configurazione dovrebbe assomigliare a questa.
[[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]#
Ora distribuendo AWX tramite Docker.
[[email protected] installer]# ansible-playbook -i inventory install.yml -vv
Questa operazione richiederà del tempo a seconda della configurazione del server.
Per verificare l'implementazione di ansible play per AWX, esegui il comando seguente.
