playbook

编写yml文件
yum文件严格遵守两个空格缩进的格式。

• 发布httpd并启动

    [devops@server1 ansible]$ cat playbook.yml 
    ---
    - hosts: prod
      tasks:
        - name: install httpd
          yum:
            name: httpd
            state: present
    
        - name: start httpd
          service:
            name: httpd
            state: started

[devops@server1 ansible]$ ansible-playbook playbook.yml --syntax-check##检测文件语法正确性

[devops@server1 ansible]$ ansible-playbook playbook.yml --list-task##检测任务

[devops@server1 ansible]$ ansible-playbook playbook.yml --list-hosts##检测生效主机

[devops@server1 ansible]$ ansible-playbook playbook.yml ##执行文件

server3查看结果

• 添加配置文件

[devops@server1 ansible]$ cat playbook.yml

[devops@server1 ansible]$ mkdir templates
[devops@server1 ansible]$ cp files/httpd.conf templates/httpd.conf.j2
[devops@server1 ansible]$ vim templates/httpd.conf.j2

推送
[devops@server1 ansible]$ ansible-playbook playbook.yml

在server2和server3查看端口
[root@server2 .ssh]# vi /etc/httpd/conf/httpd.conf
[root@server3 .ssh]# vi /etc/httpd/conf/httpd.conf


[root@server2 .ssh]# netstat -lnput | grep httpd
[root@server3 .ssh]# netstat -lnput | grep httpd

[devops@server1 ansible]$ cat file.yml
- hosts: all
  tasks:
    - name: create infofile
      template:
        src: templates/info.j2
        dest: /mnt/hostinfo

[devops@server1 ansible]$ cat templates/info.j2 
主机名: {{ ansible_facts['hostname'] }}
boot分区: {{ ansible_facts['devices']['sda']['partitions']['sda1']['size'] }}
内核: {{ ansible_facts['kernel'] }}
内存空闲: {{ ansible_facts['memfree_mb'] }}

编译运行
