我使用过puppet与salt,但这2个软件都需要安装客户端,并且更新很快,每次更新都是令人蛋疼的事,尤其是salt,喜欢他的命令功能,但bug太多,不敢在公司线上使用,puppet虽然稳定,但弄命令执行的时候,需要mco配置,非常麻烦,我公司由于跟多家公司合作,很多业务没办法安装客户端,所以没办法使用puppet与salt(虽然salt有ssh,但不太好使),最后找到了ansible,他既有命令执行也有配置管理,关键开发它的语言是python,paramiko进行ssh连接,跟我之前开发的自动管理软件都是使用paramiko进行操作,不需要安装客户端,满足我的需求,下面给大家介绍一下我是如何使用的。
一、安装
1、安装第三方epel源
centos 5的epel
1
|
rpm -ivh http: //mirrors .sohu.com /fedora-epel/5/x86_64/epel-release-5-4 .noarch.rpm |
centos 6的epel
1
|
rpm -ivh http: //mirrors .sohu.com /fedora-epel/6/x86_64/epel-release-6-8 .noarch.rpm |
查看系统版本
1
2
3
|
17:01:30 # cat /etc/issue CentOS release 6.5 (Final) Kernel \r on an \m |
由于是6版本所以安装6的epel
2、安装ansible
1
|
yum install ansible |
如果需要自定义module或者想阅读源码、使用最新版本,可以去github里下载源码
1
|
git clone https: //github .com /ansible/ansible .git |
3、添加主机

17:22:08 # cd /etc/ansible/ root@ip-10-10-10-10: /etc/ansible 17:23:27 # ll total 12 -rw-r--r-- 1 root root 5113 Dec 29 03:00 ansible.cfg -rw-r--r-- 1 root root 965 Dec 29 03:00 hosts 其中ansible.cfg是配置文件,hosts是管理主机信息 17:24:44 # cat hosts 172.17.0.2:49154 172.17.0.4:49155 [zabbix] 172.17.0.2:49154 172.17.0.4:49155 [vpn] 172.17.0.10 |
4、使用密码登陆
ansible支持正则测试

如果你有多台服务器的话,想并发运行,可以使用-f参数,默认是并发5
5、使用密钥登陆测试

11:30:35 # ansible vpn -m shell -a "echo $TERM" -u test --private-key=denglei -K SSH password: sudo password [defaults to SSH password]: 172.17.0.10 | success | rc=0 >> xterm |
二、模块应用

去客户端查看文件是否传输过来

可以看到已经传过来了
看看文件内容

11:35:09 # ansible vpn -m shell -a "cat /tmp/server" -u test --private-key=denglei -K SSH password: sudo password [defaults to SSH password]: 172.17.0.10 | success | rc=0 >> server |
内容正常
还有另外一个模块file,可以修改用户与权限

server文件是664权限,用户与组都是test

三、playbook配置管理

A.进行一下shell模块操作,测试删除文件
先查看一下客户端的server-test是否存在

[root@puppet ansible] # ansible vpn -m shell -a "ls -l /tmp/server-test" -u test --private-key=/root/denglei -k SSH password: 172.17.0.10 | success | rc=0 >> -rw-rw-r-- 1 test test 7 Jun 14 00:37 /tmp/server-test |
可以看到是存在的
然后写一个删除的playbook
