ansible plabook 小结

$ cat disk.yml 
---
- name: Mount the volume
  hosts: all
  become: yes
  become_method: sudo
  vars:
    mntname1: /data01
    mntname2: /data02
    diskname1: /dev/xvdg
    diskname2: /dev/xvdf
  tasks:

    - name: filesystem | Format
      filesystem: fstype=ext4 dev={{ item }}
      with_items:
        - "{{ diskname1 }}"
        - "{{ diskname2 }}"

    - name: Creates directory
      file: path={{ item }} state=directory
      with_items:
        - "{{ mntname1 }}"
        - "{{ mntname2 }}"


    - name: filesytem | mount dir
      shell: mount {{ diskname1 }} {{ mntname1 }} && echo "mount {{ diskname1 }} {{ mntname1 }}" >> /etc/rc.local
      sudo: yes

    - name: filesytem | mount dir
      shell: mount {{ diskname2 }} {{ mntname2 }} && echo "mount {{ diskname2 }} {{ mntname2 }}" >> /etc/rc.local
      sudo: yes

如上：为给磁盘挂载。配合ansible tower 的template选项使用。

ansible 版本为：ansible 2.3.1.0

截图如下：

　　备注：红色方框内 为赋值内容，配合plabook引用，可以正常使用。

lvm配置：

$ cat lvm.yml 
---
- name: Create and mount the lvm
  hosts: all
  become: yes
  become_method: sudo
  vars:
    mntname: /lvm-01
    pvname1: /dev/xvdg
    pvname2: /dev/xvdf
    vgname: vg01
    lv: lv01
    
  tasks:
  - name: Install LVM in Ubuntu14
    when: ansible_distribution == 'Ubuntu' and ansible_distribution_major_version == "14"
    apt: name=lvm2 state=present

  - name: Install LVM in Amazon
    when: ansible_distribution == 'Amazon'
    yum: name=lvm2 state=latest


  - name: filesystem | Create pv,vg,lv and file systems
    lvg: vg={{ vgname }}  pvs={{ pvname1 }},{{ pvname2 }}

  - name: filesystem | create lv
    lvol: vg={{ vgname }}  lv={{ lv }}  size=100%FREE

  - name: filesystem | create fs
    filesystem: fstype=ext4 dev=/dev/{{ vgname }}/{{ lv }}

  - name: Creates directory
    file: path={{ item }} state=directory
    with_items:
      - "{{ mntname }}"

  - name: filesytem | mount dir
    shell: mount /dev/{{ vgname }}/{{lv}} {{ mntname }} && echo "mount /dev/{{ vgname }}/{{lv}} {{ mntname }}" >> /etc/rc.local

　　备注：lvm制作的plabook 配合tower的提前赋值

配置 user 添加功能的plabook，如下：

$ cat user.yml 
---
- name: Create and mount the lvm
  hosts: all
  become: yes
  become_method: sudo

  vars:
    user: test
    password: test
    group: root
    shell: /bin/bash

  tasks:

  - name: Amazon Configuration file modification
    when: ansible_distribution == 'Amazon'
    lineinfile:
      dest: /etc/cloud/cloud.cfg.d/00_defaults.cfg
      regexp: "{{ item.regexp }}"
      line: "{{ item.line }}"
    with_items:
      - { regexp: '^ssh_pwauth: false', line: 'ssh_pwauth: true' }
      - { regexp: '    lock_passwd: true', line: '    lock_passwd: false' }

  - name: create {{ user }} on aws machine
    user: name={{ user }} password={{ password |password_hash('sha512') }} group={{ group }} shell={{ shell }}

  - name: config /etc/sudoers
    lineinfile: dest=/etc/sudoers state=present  line='{{item}}' validate='visudo -cf %s'
    with_items:
           - "{{ user}} ALL=(ALL) NOPASSWD: ALL"
  - name: change ssh login
    lineinfile:
      dest: /etc/ssh/sshd_config
      regexp: "{{ item.regexp }}"
      line: "{{ item.line }}"
    with_items:
      - { regexp: 'PasswordAuthentication no', line: 'PasswordAuthentication yes' }

  - name: restart sshd on Amazon linux
    when: ansible_distribution == 'Amazon'
    service: name=sshd state=restarted

  - name: restart sshd on Ubuntu14
    when: ansible_distribution == 'Ubuntu' and ansible_distribution_major_version == "14"
    service: name=ssh state=restarted

备注：vars 里边的信息可以放到tower 的yml里边做提前的声明，方式如同上面两张图片。
