学习的啥也不是

啥废话也不说！！

主题一：磁盘格式化，可在线扩容

- hosts: all
  remote_user: root

  tasks:
  - name: pvcreate disk
    shell: pvcreate {{ item }}
    with_items:
    - /dev/vdb
    register: pvcreate_result
    ignore_errors: False

  - name: pvcreate display
    shell: pvdisplay {{ item }}
    with_items:
    - /dev/vdb

  - name: vgcreate disk
    shell: vgcreate -s 4M vg_mascloud {{ item }}
    with_items:
    - /dev/vdb
    register: vgcreate_result
    ignore_errors: False
    when: pvcreate_result | success

  - name: vgcreate display
    shell: vgdisplay {{ item }}
    with_items:
    - vg_mascloud

  - name: lvcreate vg_mascloud
    shell: lvcreate -l +100%FREE -n lv_mascloud {{ item }}

    with_items:
    - lv_mascloud
    when: mke2fs_result | success

主题二：编译安装zabbix_agent3.2

    shell: chown -R zabbix.zabbix /opt/zabbix

pwd：/root/scripts
more zabbix.yml
  - hosts: mgw01
  remote_user: root

  roles:
  - zabbix

在使用zabbix-agent的playbook时，需要确定被监控端服务器的主机名，要不然zabbix-server页面的host主机名会很乱，没有统一性

批量免秘钥、修改主机名，可以查看我之间的博客
