我来为您提供一个自动配置Ansible Tower的脚本方案，这里提供两种方式：基于Ansible的自动化安装和基于Shell脚本的自动化部署。

方案1：Ansible自动化安装Tower脚本

# install_ansible_tower.yml
---
- name: 自动化安装Ansible Tower
  hosts: tower_server
  become: yes
  vars:
    tower_version: "3.8.6"
    tower_package: "ansible-tower-setup-bundle-{{ tower_version }}.tar.gz"
    tower_admin_password: "Admin123!"
    pg_password: "Pg123456!"
    rabbitmq_password: "Rabbit123!"
  tasks:
    - name: 安装必要依赖包
      yum:
        name:
          - wget
          - git
          - curl
          - python3
          - python3-pip
        state: present
    - name: 设置主机名
      hostname:
        name: "{{ inventory_hostname }}"
    - name: 添加主机名到hosts文件
      lineinfile:
        path: /etc/hosts
        line: "127.0.1.1 {{ inventory_hostname }}"
        create: yes
    - name: 创建tower用户
      user:
        name: tower
        groups: wheel
        shell: /bin/bash
    - name: 关闭防火墙和SELinux
      systemd:
        name: firewalld
        state: stopped
        enabled: no
      selinux:
        state: disabled
    - name: 下载Ansible Tower安装包
      get_url:
        url: "https://releases.ansible.com/ansible-tower/setup-bundle/{{ tower_package }}"
        dest: "/tmp/{{ tower_package }}"
        timeout: 300
    - name: 解压安装包
      unarchive:
        src: "/tmp/{{ tower_package }}"
        dest: /tmp/
        remote_src: yes
    - name: 配置安装变量
      template:
        src: inventory.j2
        dest: "/tmp/ansible-tower-setup-bundle-{{ tower_version }}/inventory"
    - name: 执行安装脚本
      shell: |
        cd /tmp/ansible-tower-setup-bundle-{{ tower_version }}
        ./setup.sh
      async: 3600
      poll: 30
    - name: 验证Tower服务状态
      shell: |
        systemctl status ansible-tower-service | grep Active
      register: tower_status
    - name: 显示Tower状态
      debug:
        msg: "{{ tower_status.stdout }}"

使用说明

使用Ansible脚本：

# 创建inventory文件
cat > inventory << EOF
[tower_server]
192.168.1.100 ansible_user=root
[all:vars]
ansible_python_interpreter=/usr/bin/python3
EOF
# 执行playbook
ansible-playbook -i inventory install_ansible_tower.yml

使用Shell脚本：

# 赋予执行权限
chmod +x auto_install_tower.sh
# 运行脚本
./auto_install_tower.sh

注意事项

1. 系统要求：

   • CentOS 7+ 或 Ubuntu 18.04+
   • 至少4GB内存
   • 至少20GB磁盘空间
   • 干净的安装环境

2. 密码设置：

   • 修改脚本中的默认密码
   • 建议使用强密码

3. 许可证：

   • 如需商业许可证,请从Red Hat购买
   • 可使用AWX作为开源替代

4. 安全建议：

   • 安装后修改默认密码
   • 配置防火墙规则
   • 启用SSL证书

此脚本会自动完成Tower的部署,根据实际环境调整配置参数。
