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
rpm -ivh http://mirrors.sohu.com/fedora-epel/5/x86_64/epel-release-5-4.noarch.rpm
centos 6的epel
rpm -ivh http://mirrors.sohu.com/fedora-epel/6/x86_64/epel-release-6-8.noarch.rpm
查看系统版本
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
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
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
16:20:57 # ansible 127* -m ping
SSH password:
127.0.0.1 | success >> {
"changed": false,
"ping": "pong"
}
root@ip-10-10-10-10:/etc/ansible
16:21:05 # ansible 172* -m ping
SSH password:
172.17.0.5 | success >> {
"changed": false,
"ping": "pong"
}
172.17.0.4 | success >> {
"changed": false,
"ping": "pong"
}
172.17.0.2 | success >> {
"changed": false,
"ping": "pong"
}
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
6、文件传输
11:30:44 # ansible vpn -m copy -a "src=/tmp/server dest=/tmp/server" -u test --private-key=denglei -K
SSH password:
sudo password [defaults to SSH password]:
172.17.0.10 | success >> {
"changed": true,
"dest": "/tmp/server",
"gid": 505,
"group": "test",
"md5sum": "e8b32bc4d7b564ac6075a1418ad8841e",
"mode": "0664",
"owner": "test",
"size": 7,
"src": "/home/test/.ansible/tmp/ansible-1402630447.45-253524136818424/source",
"state": "file",
"uid": 503
}
去客户端查看文件是否传输过来
11:34:57 # ansible vpn -m shell -a "ls -l /tmp/" -u test --private-key=denglei -K SSH password: sudo password [defaults to SSH password]: 172.17.0.10 | success | rc=0 >> total 76 -rw-r--r-- 1 root root 41692 May 21 13:02 config -rw-r--r-- 1 root root 1228 Jun 12 18:24 install_pptpd_vpn.sh -rw-rw-r-- 1 test test 7 Jun 13 19:33 server -rw-r--r-- 1 root root 82 Jun 12 18:21 test.log -rw-r--r-- 1 root root 290 Jun 12 18:21 test.sh -rw-r--r-- 1 root root 2444 Apr 28 2012 vpn_centos6.sh -rw------- 1 root root 727 Jun 10 18:21 yum_save_tx-2014-06-10-18-21UrqDAp.yumtx -rw-rw-r-- 1 zabbix zabbix 3124 Jun 12 21:32 zabbix_agentd.log -rw-rw-r-- 1 zabbix zabbix 5 Jun 12 21:32 zabbix_agentd.pid
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
下面是当前文件状态
13:50:07 # ansible vpn -m shell -a "ls -l /tmp/server" -u test --private-key=denglei -K SSH password: sudo password [defaults to SSH password]: 172.17.0.10 | success | rc=0 >> -rw-rw-r-- 1 test test 7 Jun 13 19:33 /tmp/server
server文件是664权限，用户与组都是test
修改一下
13:51:17 # ansible vpn -m file -a "dest=/tmp/server mode=755 owner=root group=root" -u test --private-key=denglei -K
SSH password:
sudo password [defaults to SSH password]:
172.17.0.10 | success >> {
"changed": true,
"gid": 0,
"group": "root",
"mode": "0755",
"owner": "root",
"path": "/tmp/server",
"size": 7,
"state": "file",
"uid": 0
}
root@ip-10-10-10-10:/etc/ansible
13:51:31 # ansible vpn -m shell -a "ls -l /tmp/server" -u test --private-key=denglei -K
SSH password:
sudo password [defaults to SSH password]:
172.17.0.10 | success | rc=0 >>
-rwxr-xr-x 1 root root 7 Jun 13 19:33 /tmp/server
7、安装软件
14:20:30 # ansible vpn -m yum -a "name=nmap state=installed" -u test --private-key=denglei -K
SSH password:
sudo password [defaults to SSH password]:
172.17.0.10 | success >> {
"changed": true,
"msg": "",
"rc": 0,
"results": [

]
}
三、playbook配置管理
8、playbook
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
[root@puppet ansible]# cat test.yml --- - hosts: vpn remote_user: test tasks: - name: delete /tmp/server-test shell: rm -rf /tmp/server-test
运行
[root@puppet ansible]# ansible-playbook test.yml --private-key=/root/denglei -k [WARNING]: The version of gmp you have installed has a known issue regarding timing vulnerabilities when used with pycrypto. If possible, you should update it (ie. yum update gmp). SSH password: PLAY [vpn] ******************************************************************** GATHERING FACTS *************************************************************** ok: [172.17.0.10] TASK: [delete /tmp/server-test] *********************************************** changed: [172.17.0.10] PLAY RECAP ******************************************************************** 172.17.0.10 : ok=2 changed=1 unreachable=0 failed=0
在查看
[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 | FAILED | rc=2 >> ls: cannot access /tmp/server-test: No such file or directory
文件已经删除
B.进行一下template模块操作，测试文件传输
[root@puppet ansible]# cat copy.yml --- - hosts: vpn remote_user: test tasks: - name: copy local server to client /tmp/server-test template: src=/tmp/server dest=/tmp/server-test [root@puppet ansible]# ansible-playbook copy.yml --private-key=/root/denglei -k [WARNING]: The version of gmp you have installed has a known issue regarding timing vulnerabilities when used with pycrypto.

C.使用service模块，测试一下服务重启
[root@puppet ansible]# ansible vpn -m shell -a "/etc/init.d/pptpd stop" -u test --private-key=/root/denglei -k -K -s SSH password: sudo password [defaults to SSH password]: 172.17.0.10 | success | rc=0 >> Shutting down pptpd: [ OK ] [root@puppet ansible]# ansible vpn -m shell -a "/etc/init.d/pptpd stop" -u test --private-key=/root/denglei -k -K -s SSH password: sudo password [defaults to SSH password]: 172.17.0.10 | success | rc=0 >> Shutting down pptpd: [ OK ]
D.多项目同时更新
[root@puppet ansible]# ansible vpn -m shell -a "ls -l /tmp/" -u test --private-key=/root/denglei -k
SSH password:
172.17.0.10 | success | rc=0 >>
