运维自动化之ansible playbook结合docker安装smokeping

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 p_w_picpaths

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

real  0m4.737s

user  0m0.038s

sys 0m0.054s

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

├── meta

│   └── main.yml

├── tasks

│   ├── copy.yml

│   ├── 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

real  6m52.934s

sys 0m1.632s

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

wKiom1PoItTggjuhAAGrTdO6Ihw932.jpg

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

wKiom1PoIxHQYHtkAADwWndNQgA311.jpg

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

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
