Ansible Tower是由RedHat开发的Ansible的图形化工具，能够以WebUI的方式实现Ansible的功能，提升管理效率。

Ansible Tower安装

截至本文发布前，Ansible Tower最新版本为3.8.6。

1	wget https://releases.ansible.com/ansible-tower/setup-bundle/ansible-tower-setup-bundle-latest.tar.gz

解压

1 2	tar -zxvf ansible-tower-setup-bundle-latest.el7.tar.gz cd ansible-tower-setup-bundle-3.8.6-2/

修改必要信息

1	nano inventory

将配置文件中的密码填上

[all:vars]
admin_password='password'

pg_host=''
pg_port=''

pg_database='awx'
pg_username='awx'
pg_password='tower'
pg_sslmode='prefer'  # set to 'verify-full' for client-side enforced SSL

执行安装
1
./setup.sh
等待执行完成后访问直接机器IP，即可出现登录页面，默认用户名是之前改的配置文件中的admin_password值。

非官方授权

/var/lib/awx/venv/awx/lib/python3.6/site-packages/awx/main/utils/licensing.py文件是有关Ansible Tower授权相关的核心代码部分，只要修改其中的部分代码绕过相关逻辑即可达到授权的目的。感谢玩脱了的奶鱼博主提供的思路。

打开该文件，找到validate函数，在attrs = copy.deepcopy(self._attrs)和type = attrs.get('license_type', 'none')之间添加如下代码：

attrs['license_type'] = 'enterprise'    # 设置License类型为企业版
attrs['instance_count'] = MAX_INSTANCES # 设置Host数量为MAX_INSTANCES，即9999999。扛不住就改成自己需要的数。
attrs['license_date'] = '2567433600'    # 设置License过期日期为”2051-05-12 00:00:00“，Unix时间戳，有需要自己改
attrs['subscription_name'] = 'lxnchan'  # 订阅名称

然后将下方的授权类型（未授权）判定部分注释掉：

1
2
3

#if (type == 'UNLICENSED' or False):
    #attrs.update(dict(valid_key=False, compliant=False))
    #return attrs

这个自定义函数全部改完之后看起来应该像这样：

def validate(self):
   # Return license attributes with additional validation info.
   attrs = copy.deepcopy(self._attrs)

   attrs['license_type'] = 'enterprise'
   attrs['instance_count'] = MAX_INSTANCES
   attrs['license_date'] = '2567433600'
   attrs['subscription_name'] = 'lxnchan'

   type = attrs.get('license_type', 'none')

   #if (type == 'UNLICENSED' or False):
      #attrs.update(dict(valid_key=False, compliant=False))
      #return attrs
   attrs['valid_key'] = True

   if Host:
      current_instances = Host.objects.active_count()
   else:
      current_instances = 0
   available_instances = int(attrs.get('instance_count', None) or 0)
   attrs['current_instances'] = current_instances
   attrs['available_instances'] = available_instances
   free_instances = (available_instances - current_instances)
   attrs['free_instances'] = max(0, free_instances)

   license_date = int(attrs.get('license_date', 0) or 0)
   current_date = int(time.time())
   time_remaining = license_date - current_date
   attrs['time_remaining'] = time_remaining
   if attrs.setdefault('trial', False):
      attrs['grace_period_remaining'] = time_remaining
   else:
      attrs['grace_period_remaining'] = (license_date + 2592000) - current_date
   attrs['compliant'] = bool(time_remaining > 0 and free_instances >= 0)
   attrs['date_warning'] = bool(time_remaining < self.SUBSCRIPTION_TIMEOUT)
   attrs['date_expired'] = bool(time_remaining <= 0)
   return attrs
