Install Chef-Solo on CentOS 5.4 x86_64

오늘 바람좀 쐬고 오느라, 어제 했던 Chef-Solo정리를 이제서야... 졸리긴 한데, 그리 좋지 않은 기억력에 요즘은 건망증까지...(ㅡ.ㅡ);;, 아무튼, 설치 과정만이라도 까먹기 전에 얼른 메모 해둬야 겠다.


설치 테스트에 사용한 OS는 CentOS 5.4 x86_64이며, VMware ESXi 상의 VM을 하나 만들어서 진행했다. 

요구사항

- Chef 설치시 hostname은 반드시 FQDN이어야 한다. hostname -f 결과가 에러가 발생하면 안됨. FQDN 명심!
- ruby >= 1.8.6 (이라고 되어 있으나, 설치 해본 결과로는 1.8.7은 되야 문제가 없었다)

- rubygems >= 1.3.6 (역시, 1.3.7은 되야 문제가 없었다)
- 권한 문제에 신경쓰기 싫어 root 계정으로 진행했다. 

RPM ruby 제거 및 관련 의존성 패키지 설치

ruby 1.8.7 (2008-05-31 patchlevel 0) [x86_64-linux] 

rubygems 설치

# cd /usr/local/src

# wget http://production.cf.rubygems.org/rubygems/rubygems-1.3.7.tgz

# tar zxvf rubygems-1.3.7.tgz 

# cd rubygems-1.3.7

# ruby setup.rb

RubyGems 1.3.7 installed

=== 1.3.7 / 2010-05-13

NOTE:

http://rubygems.org is now the default source for downloading gems.

You may have sources set via ~/.gemrc, so you should replace

http://gems.rubyforge.org with http://rubygems.org

http://gems.rubyforge.org will continue to work for the forseeable future.

New features:

* `gem` commands

  * `gem install` and `gem fetch` now report alternate platforms when a

    matching one couldn't be found.

  * `gem contents` --prefix is now the default as specified in --help.  Bug

    #27211 by Mamoru Tasaka.

  * `gem fetch` can fetch of old versions again.  Bug #27960 by Eric Hankins.

  * `gem query` and friends output now lists platforms.  Bug #27856 by Greg

    Hazel.

  * `gem server` now allows specification of multiple gem dirs for

    documentation.  Bug #27573 by Yuki Sonoda.

  * `gem unpack` can unpack gems again.  Bug #27872 by Timothy Jones.

  * `gem unpack` now unpacks remote gems.

  * --user-install is no longer the default.  If you really liked it, see

    Gem::ConfigFile to learn how to set it by default.  (This change was made

    in 1.3.6)

* RubyGems now has platform support for IronRuby.  Patch #27951 by Will Green.

Bug fixes:

* Require rubygems/custom_require if --disable-gem was set.  Bug #27700 by

  Roger Pack.

* RubyGems now protects against exceptions being raised by plugins.

* rubygems/builder now requires user_interaction.  Ruby Bug #1040 by Phillip

  Toland.

* Gem::Dependency support #version_requirements= with a warning.  Fix for old

  Rails versions.  Bug #27868 by Wei Jen Lu.

* Gem::PackageTask depends on the package dir like the other rake package

  tasks so dependencies can be hooked up correctly.

(뒤에 나올 cookbook 소스가 OPScode를 통해 이용되어 관련성이 있는 것으로 보임. 아직 자세한 연관성은 미파악상태라 좀더 알아봐야 겠다.)

chef-solo 설정 파일 작성

# cat /root/chef/solo.rb
cookbook_path "/root/chef/chef-repo/cookbooks"

(단순하다. 좀전에 git로 받아둔 cookbook의 경로를 등록해두면 된다. 단, 절대경로여야 함)


이제 Chef-Solo설치는 완료다.(빠진게 있었던가 ㅡㅡ?? 아무튼.... 잘안되면 지적질 댓글을....)
그럼, cookbook에 있는 테스트용 Recipe를 하나 시연 해보고 내용도 간략히 살펴보자.

실행할 Recipe는 "quick_start"라는 것으로, Chef를 통해 실행하게 되면, 실행된 노드의 /tmp디렉토리에 "If a tree falls in the forest..."라는 TEXT내용을 가진 deep_thought.txt 파일을 생성시킨다. 해보자. 진짜 되는지...

json 파일을 만든다. 이파일은 Chef를 통해, 수행할 작업(Recipe)을 정의 하는것 같다.

# cat /root/chef/node.json

{

        "run_list": [ "recipe[quick_start]" ]

} 

(quick_start라는, 지금 수행해보려는 Recpie가 명시되어 있다.)

(몇개의 파일과 디렉토리들이 있다.)

중요한 것은 recipes이고, 나머지는 이 recipes에 정의된 작업이 수행되는데 필요한 정보를 담고 있다. 
(template, recpites, attributes는 어떤 Recipe든지 default.rb 파일이 가장 기본이며, 먼저 읽혀지는듯 함)

# cat recipes/default.rb

template "/tmp/deep_thought.txt" do

  source "deep_thought.txt.erb"

  variables :deep_thought => node[:deep_thought]

  action :create

end 

# cat attributes/default.rb 

deep_thought "If a tree falls in the forest..."

# cat templates/default/deep_thought.txt.erb 

Todays deep thought: <%= @deep_thought %>

하나의 recipe단위 내에서 수행할 작업들을 template라는 이름으로 정의(하는듯 함...ㅡㅡ;).
여기서는 quick_start라는 Recipe를 수행하였고, 그 Recipe에는 보는 바와 같은 템플릿 하나가 등록되어 있다.
내용을 보면 대충 이해가 되리라 본다. action이 create이니 /tmp/deep_thought.txt를 생성한다는 것 같고, source는 templates/default/deep_thought.txt.erb파일을 가져다가 생성한다~ 뭐 그런... variables는 source파일을 바탕으로 생성하되, source파일 내의 deep_thought변수를  attributes/default.rb에서 정의된 값으로 바꾸어라는 그런... (이해가 안될지도 모른다. 내 설명이 엄청 저질ㅡㅡ;;이라 그런 것이니, 자책마시길...)

대충, 설치부터 간단한 샘플예제 수행까지 정상적이니 마무리 해야 겠다. 물론 더 난이도 높은 Recipe를 수행할때면,러가 뜨거나, Cookbook/Recipe에 대한 허접한 이해도로 인해, 엄청~ 삽질하겠지만, 뭐 첫술에 배부를수는 없지 않나~ 이것부터 차근차근 해두면, 곧 Chef Server/Client로 맘대로 요리(?)할 수 있지 않을까~~
