运维自动化之ansible playbook结合docker安装smokeping

qmya00

　　本次介绍ansible的paly book结合docker进行虚拟机里安装2.6.8版本smokeping（apache版本是2.4.7）。

　　docker版本
09:26:53 # docker version
Client version: 0.11.1
Client API version: 1.11
Go version (client): go1.2.1
Git commit (client): fb99f99/0.11.1
Server version: 0.11.1
Server API version: 1.11
Git commit (server): fb99f99/0.11.1
Go version (server): go1.2.1
Last stable version: 1.1.2, please update docker　　ansible版本

09:28:13 # ansible --version
ansible 1.4.3　　1、查看docker已有镜像
09:25:55 # docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
ubuntu              3.0                 6cee55276528        9 weeks ago         369.8 MB
centos5             3.0                 e08d23b09189        9 weeks ago         840.9 MB
centos6             3.0                 e94a3b24a19b        9 weeks ago         415.9 MB　　可以看到有3个镜像，1个是ubuntu，1个centos5，1个centos6.我这里打算使用centos6来弄。
　　2、加载新容器
09:31:01 # time  docker inspect $(docker run -d -p 22 -p 80:80 --name="smokeping" centos6:3.0 /usr/sbin/sshd -D)|grep -i address|awk -F '"' '{print $4}'
172.17.0.5
real0m4.737s
user0m0.038s
sys0m0.054s　　可以看到4秒就加载新容器完成，并且镜像为centos6系统，容器名为smokeping，开启了ssh服务，并且暴漏了22与80端口。
　　下面在从后端看看本机都运行了哪些容器
09:31:29 # docker ps -a
CONTAINER ID        IMAGE               COMMAND             CREATED              STATUS              PORTS                                       NAMES
56b70c31a07e        centos6:3.0         /usr/sbin/sshd -D   About a minute ago   Up About a minute   0.0.0.0:80->80/tcp, 0.0.0.0:49156->22/tcp   smokeping           
846efb9e4d7a        ubuntu:3.0          /usr/sbin/sshd -D   12 days ago          Up 4 days           0.0.0.0:49167->22/tcp                       ubuntu-test1        
b9a9e6f2caed        centos6:3.0         /usr/sbin/sshd -D   3 weeks ago          Up 4 days           0.0.0.0:49166->22/tcp                       zabbix-server      
978fff134b18        centos6:3.0         /usr/sbin/sshd -D   4 weeks ago          Up 4 days           0.0.0.0:49165->22/tcp                       centos6-test5　　下面是ansible安装smokeping的部分
　　3、ansible安装smokeping的信息

09:34:06 # cat smokeping_install/vars/main.yml
smokeping_dir: /usr/local/smokeping
smokeping_version: 2.6.8
smokeping_user: admin
smokeping_passwd: '()TF%penst*&MedHU'　　可以看到smokeping安装目录是/usr/local/smokeping，安装版本是2.6.8，登陆的账户是admin，登陆密码是()TF%penst*&MedHU
　　4、下面是安装smokeping的playbook结构
09:36:25 # tree smokeping_*
smokeping_delete
├── files
│   └── delete_smokeping.sh
├── handlers
├── meta
│   └── main.yml
├── tasks
│   ├── copy.yml
│   ├── delete.yml
│   └── main.yml
├── templates
└── vars
    ├── main.xml
    ├── main.yml
    └── vars
        └── main.yml
smokeping_install
├── files
│   ├── rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm
│   └── smokeping.tar.gz
├── handlers

│   ├── delete.yml
│   ├── install.yml
│   └── main.yml
├── templates
│   ├── config
│   └── smokeping.conf
└── vars
    └── main.yml
13 directories, 18 files　　5、playbook安装smokeping的内容是
09:37:27 # cat smokeping_install.yml
---
- hosts: "`host`"
  remote_user: "`user`"
  gather_facts: True
  roles:
    - common
    - pcre_install
    - apache_install
    - smokeping_install　　6、playbook删除smokeping的内容是
09:38:01 # cat smokeping_delete.yml
---
- hosts: "`host`"
  remote_user: "`user`"
  gather_facts: True
  roles:
    - apache_delete
    - pcre_delete
    - smokeping_delete　　下面是安装与测试过程
　　7、把docker新容器smokeping的ip加入到ansible的hosts里
echo "172.17.0.5">>/etc/ansible/hosts　　8、安装smokeping
09:39:10 # time ansible-playbook smokeping_install.yml --extra-vars "host=172.17.0.5 user=root" -k

real6m52.934s
user0m15.104s
sys0m1.632s　　花费6分52秒完成，花费时间多的主要是yum安装基础库与使用epel安装smokeping依赖库。
　　9、安装后测试

　　查看smokeping

　　由于我做了安全认证，需要输入账户与密码，这个账户与密码就上文第3步的账户与密码

　　然后默认的其他网络监控（包括1、2、3线电信、移动、联通、铁通与教育网的节点监控已经做好）

　　如果有其他的监控需要自己来添加即可。
　　10、删除

touch /var/lock/subsys/local　　如果大家想使用我的例子，可以从github里下载（地址是https://github.com/dl528888/ansible-examples/tree/master/smokeping_install），然后放到/etc/ansible目录里，下面是内容
