1. Introduction

Introduction to ansible

Ansible is a very simple IT automation platform that makes programs and systems easier to deploy.Ansible is essentially an encapsulated Shell. The advantage is that it is a de-centralized tool that enables Agent-free deployment by managing remote hosts directly through ssh.

Introduction to AWX

AWX provides a web-based user interface, REST API, and task engine built on Ansible.Graphical AWX makes it easier to organize and deploy Ansible Playbook and provides centralized logging, auditing, and system tracking.AWX is an open source version of the commercial version of Ansible Tower.

2. ansible Installation

1. Install EPEL source

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

2. Install asnible

[root@ansible-awx ~]# yum -y install ansible

Default to the latest version

[root@ansible-awx ~]# ansible --version

3. Doker Installation

1. Install dependent packages

[root@ansible-awx ~]# yum install -y yum-utils   device-mapper-persistent-data   lvm2

2. Set docker source

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

Doker Installation Version View

3. Install docker

[root@ansible-awx ~]# yum install -y docker-ce docker-ce-cli containerd.io

No version specified, default to latest version

4. Start docker

[root@ansible-awx ~]# systemctl start docker
[root@ansible-awx ~]# systemctl enable docker

5. Command Completion

5.1 Install bash-completion

[root@ansible-awx ~]# yum -y install bash-completion

5.2 Load bash-completion

[root@ansible-awx ~]# source /etc/profile.d/bash_completion.sh

6. Mirror Acceleration

Since Docker Hub's servers are abroad, downloading mirrors is slower and mirroring accelerators can be configured.The main accelerators are: Docker officially provided China registry mirror, Ali cloud accelerator, DaoCloud accelerator. This article takes Ali accelerator configuration as an example.

6.1 Landing Ali Cloud Container Module

The landing address is: https://cr.console.aliyun.com , unregistered can register Aliyun account first

6.2 Configure Mirror Accelerator

To configureDaemon.jsonfile

[root@centos7 ~]# mkdir -p /etc/docker
[root@centos7 ~]# tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://v16stybc.mirror.aliyuncs.com"]
}
EOF

Restart Service

[root@centos7 ~]# systemctl daemon-reload
[root@centos7 ~]# systemctl restart docker

Accelerator Configuration Complete

4. Install Python modules

1. Install pip3

[root@ansible-awx ~]# yum -y install python3-pip

2. Install the Python module of docker-compose

[root@ansible-awx ~]# pip3 install docker-compose

Due to network reasons, the installation process may fail, just try twice more.

5. Install Docker Compose

1. Download binaries

Download address for each version: https://github.com/docker/compose/releases

[root@ansible-awx ~]# curl -L "https://github.com/docker/compose/releases/download/1.25.5/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

2. Entitlement

[root@ansible-awx ~]# chmod +x /usr/local/bin/docker-compose

3. Installation verification

[root@ansible-awx ~]# docker-compose --version
docker-compose version 1.25.5, build 8a1c60f6

6. awx installation

1. Download awx

awx download address: https://github.com/ansible/awx/releases For this article, version 10.0.0 is selected

[root@ansible-awx ~]# wget https://github.com/ansible/awx/archive/10.0.0.tar.gz

decompression

[root@ansible-awx ~]# wget https://github.com/ansible/awx/archive/10.0.0.tar.gz

-rw-rw-r-- 1 root root 6131 3 Month 3100:42 inventory
drwxrwxr-x 7 root root   99 3 Month 3100:42 roles
[root@ansible-awx installer]# sed -i.bak 's/env python/env python3/g' inventory
[root@ansible-awx installer]# ll
//Total usage 24
-rw-rw-r-- 1 root root  167 3 Month 3100:42 build.yml
-rw-rw-r-- 1 root root  437 3 Month 3100:42 install.yml

3. Download Mirror

3.1 Mirror Download

[root@ansible-awx ~]# docker pull registry.cn-hangzhou.aliyuncs.com/loong576/awx_web:10.0.0
[root@ansible-awx ~]# docker pull registry.cn-hangzhou.aliyuncs.com/loong576/awx_task:10.0.0
[root@ansible-awx ~]# docker pull registry.cn-hangzhou.aliyuncs.com/loong576/memcached:alpine
[root@ansible-awx ~]# docker pull registry.cn-hangzhou.aliyuncs.com/loong576/postgres:10
[root@ansible-awx ~]# docker pull registry.cn-hangzhou.aliyuncs.com/loong576/redis

The components of awx are installed in containers and the corresponding version of the image is downloaded separately. The image download will take some time. Please keep the network environment stable.

3.2 tag

[root@ansible-awx ~]# docker tag registry.cn-hangzhou.aliyuncs.com/loong576/awx_task:10.0.0 ansible/awx_task:10.0.0
[root@ansible-awx ~]# docker tag registry.cn-hangzhou.aliyuncs.com/loong576/awx_web:10.0.0 ansible/awx_web:10.0.0 
[root@ansible-awx ~]# docker tag registry.cn-hangzhou.aliyuncs.com/loong576/redis redis
[root@ansible-awx ~]# docker tag registry.cn-hangzhou.aliyuncs.com/loong576/postgres:10 postgres:10 
[root@ansible-awx ~]# docker tag registry.cn-hangzhou.aliyuncs.com/loong576/memcached:alpine memcached:alpine

3.3 Remove unwanted mirrors

[root@ansible-awx ~]# docker rmi registry.cn-hangzhou.aliyuncs.com/loong576/awx_web:10.0.0 registry.cn-hangzhou.aliyuncs.com/loong576/redis registry.cn-hangzhou.aliyuncs.com/loong576/postgres:10 registry.cn-hangzhou.aliyuncs.com/loong576/memcached:alpine
