Puppet基础篇9-Puppetmaster多环境配置

零基础学习Puppet自动化配置管理系列文档

扩充现有架构环境是对一个企业成长的见证

将基础环境模块部署到puppetmaster端之后就可以初始化所有节点了,接下来就是部署应用代码了。众所周知,一个企业中应用代码的编写并不是运维一个人完成的,而且代码的上线也不是一次性完成的。标准的架构应该由开发、测试、生产三个组成,对应到puppetmaster里面应该有3套代码才对。而且每套代码都应该对应到自己的环境中,而代码的变更更应该通过版本控制工具进行管理,比如svn、git等。 接下来我们为puppetmaster创造3个环境,它们分别是开发环境(kissdev)、测试环境(kissqa)、生产环境(kissprd).

1、配置puppet.conf

在标签[master]中添加environments环境,其次创建对应的环境标签及配置

[root@puppetmaster ~]# vim /etc/puppet/puppet.conf
[main]
    logdir = /var/log/puppet
    rundir = /var/run/puppet
    ssldir = $vardir/ssl
[agent]
    classfile = $vardir/classes.txt
    localconfig = $vardir/localconfig
    server = puppetmaster.kisspuppet.com
    certname = puppetmaster_cert.kisspuppet.com
[master]
    certname = puppetmaster.kisspuppet.com
    environments = kissdev,kisstmq,kissprd  #添加三个环境的标签名称
[kissdev]
modulepath = $confdir/environments/kissdev/environment/modules:$confdir/environments/kissdev/application/modules  #设置环境的搜索路径
manifest = $confdir/environments/kissdev/manifests/site.pp  #设置环境的site.pp文件位置
fileserverconfig = /etc/puppet/fileserver.conf.kissdev  #设置环境的fileserver
[kissmq]
modulepath = $confdir/environments/kissmq/environment/modules:$confdir/environments/kisstest/application/modules
manifest = $confdir/environments/kisstest/manifests/site.pp
fileserverconfig = /etc/puppet/fileserver.conf.kisstest
[kissprd]
modulepath = $confdir/environments/kissprd/environment/modules:$confdir/environments/kissprd/application/modules
manifest = $confdir/environments/kissprd/manifests/site.pp
fileserverconfig = /etc/puppet/fileserver.conf.kissprd

顺便解释一下:为什么在每个环境下会有environment和application两个目录,其中environment目录是存放基础环境模块的,比如puppet、yum等;而application目录是存在应用环境模块的,比如apache、mysql等。当然也可以放在同一个目录下,如果应用多的话还可以将application进行拆分,一切都是为了方便管理而考虑。

2、创建多环境目录结构

[root@puppetmaster environments]# mkdir kissdev
[root@puppetmaster environments]# mkdir kissdev/{application/modules,environment/modules} -p
[root@puppetmaster environments]# tree .
.
└── kissdev
    ├── application
    │   └── modules   #存放应用的模块
    └── environment
        └── modules  #存放基础环境模块
5 directories, 0 files
[root@puppetmaster environments]# cp kissdev kissmq -rp
[root@puppetmaster environments]# cp kissdev kissprd -rp
[root@puppetmaster environments]# tree .
.
├── kissdev
│   ├── application
│   │   └── modules
│   └── environment
│       └── modules
├── kissmq
│   ├── application
│   │   └── modules
│   └── environment
│       └── modules
└── kissprd
    ├── application
    │   └── modules
    └── environment
        └── modules
15 directories, 0 files

3、移动默认环境modules中的配置到kissprd对应的环境中

其中puppet和yum模块属于基础环境模块,motd属于应用环境模块

[root@puppetmaster environments]# mv /etc/puppet/modules/puppet kissprd/environment/modules/ 
[root@puppetmaster environments]# mv /etc/puppet/modules/yum  kissprd/environment/modules/ 
[root@puppetmaster environments]# mv /etc/puppet/modules/motd kissprd/application/modules/

4、复制manifests文件至kissprd环境中

[root@puppetmaster environments]# cp /etc/puppet/manifests kissprd/ -r

复制完成后整个环境如下

[root@puppetmaster environments]# tree kissprd/
kissprd/
├── application
│   └── modules
│       └── motd
│           ├── files
│           │   └── etc
│           │       └── motd
│           ├── manifests
│           │   └── init.pp
│           └── templates
├── environment
│   └── modules
│       ├── puppet
│       │   ├── files
│       │   ├── manifests
│       │   │   ├── config.pp
│       │   │   ├── init.pp
│       │   │   ├── install.pp
│       │   │   ├── params.pp
│       │   │   └── service.pp
│       │   └── templates
│       │       └── puppet.conf.erb
│       └── yum
│           ├── files
│           │   ├── etc
│           │   │   └── yum.conf
│           │   └── PM-GPG-KEY
│           │       ├── RPM-GPG-KEY-puppet-release
│           │       ├── RPM-GPG-KEY-redhat-release-rhel5
│           │       └── RPM-GPG-KEY-redhat-release-rhel6
│           ├── manifests
│           │   ├── config.pp
│           │   ├── init.pp
│           │   ├── install.pp
│           │   └── params.pp
│           └── templates
└── manifests
    └── site.pp
20 directories, 17 files

5、删除掉默认环境manifests中site.pp文件内容

因为模块已经移除,其次默认环境production已经不再使用了。

[root@puppetmaster environments]# >/etc/puppet/manifests/site.pp 

6、创建fileserverconfig文件

[root@puppetmaster ~]# cp /etc/puppet/fileserver.conf{,.kissdev}
[root@puppetmaster ~]# cp /etc/puppet/fileserver.conf{,.kissqa}
[root@puppetmaster ~]# cp /etc/puppet/fileserver.conf{,.kissprd}
[root@puppetmaster ~]# ll /etc/puppet/
total 88
-rw-r--r-- 1 root root  2569 Jan  7 07:51 auth.conf
-rw-r--r-- 1 root root    17 Mar  9 17:54 autosign.conf.bak
drwxr-xr-x 5 root root  4096 Mar 27 22:33 environments
-rw-r--r-- 1 root root   381 Jan  7 07:49 fileserver.conf
-rw-r--r-- 1 root root   381 Mar 27 22:46 fileserver.conf.kissdev  #指向kissdev环境
-rw-r--r-- 1 root root   381 Mar 27 22:46 fileserver.conf.kissprd  #指向kissmq环境
-rw-r--r-- 1 root root   381 Mar 27 22:46 fileserver.conf.kissqa   #指向kissdev环境
drwxr-xr-x 2 root root  4096 Mar 25 05:23 manifests
drwxr-xr-x 2 root root  4096 Mar 27 22:40 modules
-rw-r--r-- 1 root root  1063 Mar 27 21:55 puppet.conf
-rw-r--r-- 1 root root   853 Mar  9 00:48 puppet.conf.bak
-rw-r--r-- 1 root root 42031 Mar  9 03:25 puppet.conf.out

7、重启puppetmaster服务

[root@puppetmaster ~]# /etc/init.d/puppetmaster restart
Stopping puppetmaster:                                     [  OK  ]
Starting puppetmaster:                                     [  OK  ]

8、节点测试验证

[root@agent1 ~]# >/etc/motd 
You have new mail in /var/spool/mail/root
[root@agent1 ~]# puppet agent -t  #默认请求的是production环境,由于此环境里面没有模块所有不更新
info: Caching catalog for agent1_cert.kisspuppet.com

--                       --

--                       --

9、节点更改环境

如果节点是主动同步的方式,应该在puppet.conf文件中添加environment配置

[root@agent1 ~]# vim /etc/puppet/puppet.conf
### config by  puppet ###
[main]
    logdir = /var/log/puppet
    rundir = /var/run/puppet
    ssldir = $vardir/ssl
[agent]
    classfile = $vardir/classes.txt
    localconfig = $vardir/localconfig
    server = puppetmaster.kisspuppet.com
    certname = agent1_cert.kisspuppet.com
    runinterval = 10
    environment =kissprd   #添加默认环境为kissprd

10、继续测试

[root@agent1 ~]# puppet agent -t

备注: 记得设置puppet模块中的puppet.conf.erb模板,否则会被还原哦。

后续问题

1、puppetmaster端有三套环境,那么如何管理呢,接下来就应该考虑版本控制系统了,这里已经有写了http://rsyslog.org/2013/11/16/svn-puppet/

2、后面讲的hiear中关于设置的变量对应到每个环境中是如何解决的。

关于多环境的部署有不理解的还可以参考书籍《精通Puppet配置管理工具》或者官网
