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)。

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、查看docker已有镜像

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

09:34:06 # 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

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。
