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/modulesmanifest = $confdir/environments/kisstest/manifests/site.ppfileserverconfig = /etc/puppet/fileserver.conf.kisstest[kissprd]modulepath = $confdir/environments/kissprd/environment/modules:$confdir/environments/kissprd/application/modulesmanifest = $confdir/environments/kissprd/manifests/site.ppfileserverconfig = /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 └── modules15 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.pp20 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.bakdrwxr-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 manifestsdrwxr-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 restartStopping puppetmaster: [ OK ]Starting puppetmaster: [ OK ]
8、节点测试验证
[root@agent1 ~]# >/etc/motdYou 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.cominfo: Applying configuration version '1395931884'notice: Finished catalog run in 0.02 seconds[root@agent1 ~]# puppet agent -t --environment=kissprd #环境指向kissprdinfo: Caching catalog for agent1_cert.kisspuppet.cominfo: Applying configuration version '1395931962'notice: /Stage[main]/Motd/File[/etc/motd]/content:--- /etc/motd 2014-03-27 22:52:27.000000000 +0800+++ /tmp/puppet-file20140327-26204-29bst1-0 2014-03-27 22:52:44.000000000 +0800@@ -0,0 +1,3 @@+-- --+--------puppet test---------+-- --info: FileBucket got a duplicate file {md5}d41d8cd98f00b204e9800998ecf8427einfo: /Stage[main]/Motd/File[/etc/motd]: Filebucketed /etc/motd to puppet with sum d41d8cd98f00b204e9800998ecf8427enotice: /Stage[main]/Motd/File[/etc/motd]/content: content changed '{md5}d41d8cd98f00b204e9800998ecf8427e' to '{md5}87ea3a1af8650395038472457cc7f2b1'notice: Finished catalog run in 0.68 seconds[root@agent1 ~]# cat /etc/motd-- ----------puppet test----------- --
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 -tinfo: Caching catalog for agent1_cert.kisspuppet.cominfo: Applying configuration version '1395931962'notice: /Stage[main]/Motd/File[/etc/motd]/content:--- /etc/motd 2014-03-27 22:55:43.000000000 +0800+++ /tmp/puppet-file20140327-30010-8ada2g-0 2014-03-27 22:56:19.000000000 +0800@@ -0,0 +1,3 @@+-- --+--------puppet test---------+-- --info: FileBucket got a duplicate file {md5}d41d8cd98f00b204e9800998ecf8427einfo: /Stage[main]/Motd/File[/etc/motd]: Filebucketed /etc/motd to puppet with sum d41d8cd98f00b204e9800998ecf8427enotice: /Stage[main]/Motd/File[/etc/motd]/content: content changed '{md5}d41d8cd98f00b204e9800998ecf8427e' to '{md5}87ea3a1af8650395038472457cc7f2b1'notice: /Stage[main]/Puppet::Config/File[/etc/puppet/puppet.conf]/content:--- /etc/puppet/puppet.conf 2014-03-27 22:56:14.000000000 +0800+++ /tmp/puppet-file20140327-30010-cmjg48-0 2014-03-27 22:56:19.000000000 +0800@@ -10,4 +10,3 @@ server = puppetmaster.kisspuppet.com certname = agent1_cert.kisspuppet.com runinterval = 10- environment =kissprdinfo: FileBucket got a duplicate file {md5}43df60b1aa2638c5f10aa7e6be892b77info: /Stage[main]/Puppet::Config/File[/etc/puppet/puppet.conf]: Filebucketed /etc/puppet/puppet.conf to puppet with sum 43df60b1aa2638c5f10aa7e6be892b77notice: /Stage[main]/Puppet::Config/File[/etc/puppet/puppet.conf]/content: content changed '{md5}43df60b1aa2638c5f10aa7e6be892b77' to '{md5}8c67cb8c039bb6436556b91f0c6678c4'info: /Stage[main]/Puppet::Config/File[/etc/puppet/puppet.conf]: Scheduling refresh of Class[Puppet::Service]info: Class[Puppet::Service]: Scheduling refresh of Service[puppet]notice: /Service[puppet]/ensure: ensure changed 'stopped' to 'running'notice: /Service[puppet]: Triggered 'refresh' from 1 eventsnotice: Finished catalog run in 0.68 seconds[root@agent1 ~]# cat /etc/motd-- ----------puppet test----------- --
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
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
