1、經過playbook安裝與設置zookeeper

---                                       #必須字段，類同於#/bin/bash
- hosts: test                        #遠程操做主機
  remote_user: cedar          #遠程操做用戶
  become: yes                    #是否sudo 
  tasks:
    - name: "安裝zookeeper"                                                      #任務命名
      command: yum -y install mesosphere-zookeeper              #遠程執行命令安裝zook
    - name: "啓動zookeeper"                                   #任務命名
      service:                                                             #service模塊
        name: zookeeper                                           #服務名zookeeper
        state: started                                                  #動做started
    - name: "設置開機啓動"                                     #任務命名
      service:                                                            #service模塊
        name: zookeeper                                           #服務名zookeeper
        enabled: yes                                                  #enabled參數爲YES開機啓動
