Ansible 部署及相关技术应用

1. Ansible 应用部署

1.1 安装 Hazelcast

我们可以在新的 playbook 中指定一个 play。创建 playbook.yml 文件，内容如下：

---
- hosts: web1
  become: yes
  become_method: sudo
  tasks:
  - name: ensure Java Runtime Environment is installed
    apt: 
      name: default-jre
      state: present
      update_cache: yes
  - name: create Hazelcast directory
    file:
      path: /var/hazelcast
      state: directory
  - name: download Hazelcast
    get_url:
      url: https://repo1.maven.org/maven2/com/hazelcast/hazelcast/5.0.2/hazelcast-5.0.2.jar
      dest: /var/hazelcast/hazelcast.jar
      mode: a+r
  - name: copy Hazelcast starting script
    copy:
      src: hazelcast.sh
      dest: /var/hazelcast/hazelcast.sh
