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 CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 318c7c95dcbb ansible/awx_task:latest "/tini -- /bin/sh -c." 12 minutes ago Up 12 minutes 8052/tcp awx_task 642c2f272e31 ansible/awx_web:latest "/tini -- /bin/sh -c." 12 minutes ago Up 12 minutes 0.0.0.0:80->8052/tcp awx_web 641b42ab536f memcached:alpine "docker-entrypoint.s." 18 minutes ago Up 18 minutes 11211/tcp memcached b333012d90ac rabbitmq:3 "docker-entrypoint.s." 19 minutes ago Up 19 minutes 4369/tcp, 5671-5672/tcp, 25672/tcp rabbitmq ada52935513a postgres:9.6 "docker-entrypoint.s." 19 minutes ago Up 19 minutes 5432/tcp postgres [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]----+ | +o==.+. | | O.oo . | | * @ . | | + @ * + | | S * = o | | B =.o o | | ..=.o.o .| | .E... o | | .oo.o. | +----[SHA256]-----+ [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。
