一、软件环境

  • CentOS 7.9（最小化安装）
  • Ansible 2.9.25
  • Ansible-tower 3.8.3

二、安装

1、离线安装Ansible

先使用一台可以联网的虚拟机，下载所有需要的依赖包

# yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

# yum install ansible --downloadonly --downloaddir=./

然后，将所有rpm包上传到没有网络的离线服务器（模拟生产环境的内网服务器），然后一条命令即可完成安装操作。

检查ansible的版本信息

# ansible --version
ansible 2.9.25
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/site-packages/ansible
  executable location = /usr/bin/ansible
  python version = 2.7.5 (default, Nov 16 2020, 22:23:17) [GCC 4.8.5 20150623 (Red Hat 4.8.5-44)]

2、安装Ansible-tower

从下面的页面下载3.8.3版本的Ansible-tower

https://releases.ansible.com/ansible-tower/setup-bundle/

上传到服务器，解压，修改安装目录下的inventory文件，设置相关的密码字段。

创建日志目录，这一步不执行，会导致安装过程报错中断

# mkdir -p /var/log/tower

执行./setup.sh即可开始安装。 

【勘误-20211123】

如果虚拟机完全断网，下面的安装会报错中断。经过测试发现，Ansible-tower在安装过程中还需要安装特定的组件（如：rh-postgres10-postgres、rh-redis5等），以及300多个依赖包。

Ansible-tower服务管理的基本命令：
