在一个角色中启用多个主机

我如何编写单一角色并随着脚本的进展连接到不同的主机？

这是我想要做的一个例子，但我收到了如下所示的错误。

ERROR! no action detected in task. This often indicates a misspelled module name, or incorrect module path.

The error appears to be in '/etc/ansible/roles/customer_setups/microlight/customer_app_template/tasks/main.yml': line 3, column 3, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

# tasks file for /etc/ansible/roles/customer_app_template
- hosts: synbill-apps
  ^ here


---
# tasks file for /etc/ansible/roles/customer_app_template
- hosts: synbill-apps
  tasks:
  - name: Clone syndicatebilling repository into a new customer app
    git:
      repo: [email protected]:xxxx/xxx.git
      version: syndicateBookings
      dest: /var/www/html/microlight
      force: yes
  - name: run npm install
    npm:
      path: /var/www/html/microlight
  - name: copy .env file
    copy:
      src: files/.env
      dest: /var/www/html/microlight/.env
  - name: create new app key
    command: chdir=/var/www/html/microlight adonis key:generate
  - name: migrate database
    command: chdir=/var/www/html/microlight adonis migration:run --force
  - name: start the app
    command: chdir=/var/www/html/microlight pm2 start server.js --name placeholder_domain
  - name: save the pm2 config
    command: chdir=/var/www/html/microlight pm2 save
- hosts: synbill-db
  - name: "Install Mysql Client package"
    apt:
      name: "{{ item }}"
      state: present
    with_items:
      - mysql-client
      - python3-dev
      - libmysqlclient-dev
      - python3-mysqldb
  - name: Create syndicate database
    mysql_db:
      name: microlight
      state: present
      login_user: simon
      login_password: xxxxxxxxxxx
- hosts: synbill-apps
  .....now the db is setup do some more work on the apps server
- hosts: synbill-webserver
  .... now setup the virtual host
- hosts: synbill-db
  .... now update the database to so user knows everything is setup.

文件中的任务tasks.yml看起来不太适合角色抽象。我只想写一个剧本。

为了能够执行剧本，您需要在此处添加“任务部分”：

- hosts: synbill-db
  tasks:
  - name: "Install Mysql Client package"

我认为用角色抽象代码的最简单的方法是编写两个角色，一个用于应用程序，一个用于数据库。
