ansible批量分发文件含自动备份原文件
目前公司网站前台有16台，每次想更新个文件，手动更新真的很让人抓狂。现在就借助ansible的copy模块轻松实现批量分发，并自动备份，效果还不错，拿来分享给大家。1.前提要安装好ansible且要与前台16台服务器，做好ssh信任，并归类到一组如v2_51auto_www。
# cat /etc/ansible/hosts
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
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.把要更新的文件上传到ansible服务器，我的目录是/home/maser/upload
$ pwd
/home/master/upload
$ ls
list.jspParamUtils.classTempUtil.class
3.ansible命令分发
$ 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.验证效果
# ifconfig
