ansible基本操做

ansible基本操做

 

ansible模塊

一、主機連通性測試

ansible qf -m   ping

 

二、command模塊  ，默認就是command模塊

 

三、shell模塊

ansible qf  -m  shell  -a  'cat  /etc/passwd | grep "root"'

 

4.copy模塊

====================

- hosts: qf

  vars:

    IP: "{{ ansible_ens33['ipv4']['address'] }}"

  tasks:

  - name: 將原有的hosts文件備份

    shell: mv /etc/hosts /etc/hosts_bak

  - name: 將ansible端的hosts複製到各自機器上

    copy: src=/root/hosts dest=/etc/ owner=root group=root mode=0644

  - name: 將新的hosts文件後面追加各自機器內網和hostname

    lineinfile: dest=/etc/hosts line="{{ IP }} {{ ansible_hostname }} "

=======================

  - name: copy {{ rpmname }}.conf   

    copy: src=/tmp/{{ rpmname }}.conf.j2 dest=/etc/{{ rpmname }}/{{ rpmname }}.conf  backup=yes

ansible qf -m copy  -a  'content="jfsakf\n" dest=/data/name mode=666'

 

5.file模塊

ansible qf -m  file -a 'path=/data/app state=directory'

  - name: 建立目錄

    file: path=/data/a state=directory

       file: path=/data/a state=absent  //刪除

6.fetch模塊

ansible qf -m fetch -a 'src=/data/hello.txt dest=/data'  //只能是文件

 

7.cron計劃任務模塊      

ansible qf -m cron -a 'name="ntp update every 5 min" minute=*/5 job="/sbin/ntpdate 172.17.0.1 &> /dev/null"'      

ansible qf -m cron -a 'name="df everyday" hour=15 job="df -lh >> /tmp/disk_total &> /dev/null" state=absent'

      

8.yum模塊

name=  #所安裝的包的名稱

state =  #present--->安裝， latest--->安裝最新的, absent---> 卸載軟件。

  - name: install httpd

    yum: name=httpd state=present

 

9.service模塊

ansible qf -m service -a 'name=nginx state=started enabled=true'

- name: start {{ rpmname }} service

      service: name={{ rpmname }} state=started//stopped//restarted

        

10.user模塊

ansible qf -m user -a 'name=keer uid=11111'

 

11.group模塊

ansible qf -m group -a 'name=sanguo gid=12222'

 

12.script模塊

vim  /tmp/df.sh

chmod  -v  +x  df.sh

ansible web -m script -a '/tmp/df.sh'

 

13.setup模塊

ansible web -m setup -a 'filter="*mem*"'   #查看內存
