1、RH294自动创建环境

[student@workstation ~]$ lab playbook-basic start

Setting up workstation for lab exercise work:

 · Verifying Ansible installation..............................  SUCCESS
 · Creating working directory..................................  SUCCESS
 · Deploying Ansible inventory.................................  SUCCESS
 · Deploying ansible.cfg.......................................  SUCCESS
 · Downloading index.html......................................  SUCCESS

[student@workstation ~]$ ll

[student@workstation playbook-basic]$ ll

drwxr-xr-x. 2 student student  24 Sep 17 22:22 files
-rw-r--r--. 1 student student  55 Sep 17 22:25 inventory

[student@workstation playbook-basic]$ cat ansible.cfg 
[defaults]
inventory=inventory
remote_user=devops

[privilege_escalation]
become=True
become_method=sudo
become_user=root
become_ask_pass=False

[student@workstation playbook-basic]$ vim inventory 

[web]
serverc.lab.example.com
serverd.lab.example.com

2、编写剧本

[student@workstation playbook-basic]$ vim site.yml 

---
- name: install and start Apache HTTPD
  hosts: web
  tasks:
    - name: httpd package is present   #安装httpd
      yum:   #模块名
        name: httpd    #指定软件包名
        state: present  

    - name: firewalld package is present  #安装firewalld
      yum:
        name: firewalld
        state: present

    - name: create index.html   #创建网站资源文件
      copy:
        content: "Welcome to the example.com"    #网页内容
        dest: /var/www/html/index.html        #网页文件路径

    - name: httpd is started  #启动httpd
      service:
        name: httpd
        state: started
        enabled: true   #开机启动

    - name: firewalld is started   #启动firewalld
      service:
        name: firewalld
        state: started
        enabled: true

    - name: firewall-rule    #防火墙规则
      firewalld:
        service: http     #协议或80/tcp
        permanent: true   #永久生效
        immediate: true   #立即生效
        state: enabled

- name: test   #测试
  hosts: web
  tasks:
    - name: web testing
      uri:
        url: http://serverc.lab.example.com
        return_content: yes  #接收返回结果
        status_code: 200   #能返回200，代表接收成功

3、运行测试

[student@workstation playbook-basic]$ ansible-playbook site.yml
