运维自动化之ansible playbook结合docker安装smokeping

linre

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

1 2 3 4 5 6 7 8 9 10

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

1 2	09:28:13 # ansible --version ansible 1.4.3

1、查看docker已有镜像

1 2 3 4 5

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

1 2 3 4 5 6

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

1 2 3 4 5 6

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

1 2 3 4 5

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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36

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

1 2 3 4 5 6 7 8 9 10

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

1 2 3 4 5 6 7 8 9

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

1	echo "172.17.0.5">>/etc/ansible/hosts

8、安装smokeping

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125

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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42

11、删除后测试

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50

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/ansi ... r/smokeping_install），然后放到/etc/ansible目录里，下面是内容
