如何在CentOS 7上安装带有Docker的Ansible AWX

Ansible AWX是开放源码塔的开源版本。 AWX提供基于Web的用户界面，REST API和构建在Ansible之上的任务引擎。它是AWX的商业衍生品Tower的上游项目。

在本教程中，我将向您展示如何使用Docker安装和配置AWX。

我将使用带有centos 7的3台服务器，最低安装和SELinux处于宽容模式。

192.168.1.25 AWX服务器
192.168.1.21 client1
192.168.1.22 client2

AWX服务器的系统要求

至少4GB的内存。
至少2个cpu核心。
至少20GB的空间。
运行Docker，Openshift或Kubernetes。

检查SELinux配置。

sestatus

结果：

[root@awx ~]# 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
[root@awx ~]#

禁用firewalld。

[root@awx installer]# systemctl stop firewalld
[root@awx 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.
[root@awx installer]#

在/ etc / hosts中添加主机条目

[root@awx ~]# 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
[root@awx ~]#

启用epel回购。

[root@awx ~]# yum install -y epel-release

安装软件包。

[root@awx ~]# yum install -y yum-utils device-mapper-persistent-data lvm2 ansible git python-devel python-pip python-docker-py vim-enhanced

配置docker ce stable库。

[root@awx ~]# yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

安装docker。

[root@awx ~]# yum install docker-ce -y

开始码头服务。

[root@awx ~]# systemctl start docker

启用docker服务。

[root@awx ~]# systemctl enable docker

克隆AWX回购。

[root@awx ~]# git clone https://github.com/ansible/awx.git
[root@awx ~]# cd awx/
[root@awx awx]# git clone https://github.com/ansible/awx-logos.git
[root@awx awx]# pwd
/root/awx
[root@awx awx]#

进入/ root / awx中的安装程序目录。

[root@awx awx]# cd installer/

在清单中编辑以下参数。

[root@awx awx]# vim inventory
postgres_data_dir=/var/lib/pgdocker
awx_official=true
awx_alternate_dns_servers="4.2.2.1,4.2.2.1"
project_data_dir=/var/lib/awx/projects

你的配置应该看起来像这样。

[root@awx 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
[root@awx installer]#

现在通过Docker部署AWX。

[root@awx installer]# ansible-playbook -i inventory install.yml -vv

这将需要一段时间，取决于服务器的配置。

要检查适用于AWX的部署，请运行以下命令。

[root@awx installer]# docker container ls

[root@awx installer]#

AWX已准备就绪，可以通过浏览器访问。

用户名是“admin”，密码是“password”。

从AWX服务器配置无密码登录

在所有3台主机上创建一个用户。在所有3台服务器上按照以下步骤操作。

[root@awx ~]# useradd ansible
[root@client1 ~]# useradd ansible
[root@clien2 ~]# useradd ansible

生成ssh密钥：

[root@awx ~]# su - ansible
[ansible@awx ~]$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/home/ansible/.ssh/id_rsa):
Created directory '/home/ansible/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/ansible/.ssh/id_rsa.
Your public key has been saved in /home/ansible/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:j30gyTVQxcWIocdKMbVieZvfJzGkCjXhjtc5qu+fE8o ansible@awx.sunil.cc
The key's randomart image is:
+---[RSA 2048]----+

[ansible@awx ~]$

在所有3台服务器上添加sudoers条目作为该文件的最后一个条目。

[root@awx ~]# visudo
ansible ALL=(ALL) NOPASSWD: ALL

将所有3台服务器上的id_rsa.pub的内容复制到authorized_keys。

[ansible@awx .ssh]$ cat id_rsa.pub
