目前公司網站前臺有16臺，每次想更新個文件，手動更新真的很讓人抓狂。現在就藉助ansible的copy模塊輕鬆實現批量分發，並自動備份，效果還不錯，拿來分享給大家。
1.前提要安裝好ansible且要與前臺16臺服務器，做好ssh信任，並歸類到一組如v2_51auto_www。
# cat /etc/ansible/hosts
[v1_51auto_www]
172.31.2.68 ansible_ssh_port=22
172.31.2.69 ansible_ssh_port=22
172.31.2.70 ansible_ssh_port=22
172.31.2.71 ansible_ssh_port=22
172.31.2.72 ansible_ssh_port=22
172.16.1.20
172.16.1.21
172.16.1.22
172.16.1.23
172.16.1.24
[v2_51auto_www]
172.16.1.11
172.16.1.12
172.16.1.13
172.16.1.14
172.16.1.19
172.16.1.34
2.把要更新的文件上傳到ansible服務器，我的目錄是/home/maser/upload
[master@localhost upload]$ pwd
/home/master/upload
[master@localhost upload]$ ls
list.jsp ParamUtils.class TempUtil.class
3.ansible命令分發
[master@localhost upload]$ ansible v2_51auto_www -s -m copy -a 'src=/home/master/upload/list.jsp dest=/opt/websuite/resin/data/webapps/ROOT/views/car/promotion owner=websuite group=websuite backup=yes'
4.驗證效果
[root@s01 promotion]# ifconfig
