JRuby1.5.1下執行Rails2.2.2應用

    JRuby1.5.1下執行Rails2.2.2應用

 

最近要把我的一個RoR專案賣給客戶,為了進行產權保護,研究了一下JRuby的打包,記錄如下

 

 

---

 

1. 下載/安裝JRuby
   • JRuby 下載地址 http://jruby.org/download
   • 下載Windows版本,然後安裝到C盤下
     • 安裝的時候自動設定PATH,方便不少.
     • 執行 jruby -v 驗證安裝成功
2. 安裝Rails 2.2.2
   1. jruby -S gem install rails -v 2.2.2
3. 安裝JDBC驅動
   1. JDBC
      • jruby -S gem install activerecord-jdbc-adapter 
   2. Sqlite3
      • jruby -S gem install activerecord-jdbcsqlite3-adapter 
   3. MySQL
      • jruby -S gem install activerecord-jdbcmysql-adapter
4. 安裝Sqlite3資料庫
   1. 下載Sqlit3
   2. 放置sqlite3.exe和sqlite3.dll到JRUBY/bin下
5. 建立Rails 專案
   • > jruby -S rails myapp
   • > cd myapp
   • # 生成一個介面
   • > jruby script/generate scaffold post title:string body:text published:boolean
   • #建立資料庫，如果失敗，檢查sqlite3.exe是否在PATH中
   • > jruby -S rake db:create
   • #匯入資料
   • > jruby -S rake db:migrate
   • #啟動伺服器
   • > jruby script/server
   • #測試地址1
   • http://localhost:3000
   • #測試地址2
   • http://localhost:3000/posts
6. 修改config
   1. myapp/config/database.yml
   2. development: adapter: jdbcsqlite3 database: db/development.sqlite3 pool: 5 timeout: 5000 
7. 利用warbler打包
   • 安裝
   •    > jruby -S gem install warbler
   • 生成config配置
   •    > jruby -S warble config
   • 修改warble.rb配置
   •      # You can also use regexps or Gem::Dependency objects for flexibility or # fine-grained control. # config.gems << /^merb-/ # config.gems << Gem::Dependency.new("merb-core", "= 0.9.3") #追加一下程式碼 %w{activerecord-jdbcsqlite3-adapter activerecord-jdbc-adapter}.each{|g| config.gems << g} 
   • 生成war包
   •    > jruby -S warble war
   • 把生成的myapp.war放在tomcat下執行。
   • 雖然可以在Tomcat下執行Rails程式，但是開啟War包一看,還是rb程式碼。所以還要用AOT模式重新打一次
8. 利用warbler進行AOT模式打包
   1. 下載唐力群修改過得warbler包，地址為 http://github.com/crazycode/warbler
   2. 下載後解壓縮，覆蓋C:/jruby-1.5.1/lib/ruby/gems/1.8/gems/warbler-1.1.0下內容
   3. 執行warble -T,會多出war:aot 
   4. rake config # Generate a configuration file to customize your w... rake pluginize # Unpack warbler as a plugin in your Rails application rake version # Display version of warbler rake war # Create Administrator.war rake war:aot # Create AOT Administrator.war rake war:app # Copy all application files into the .war rake war:clean # Clean up the .war file and the staging area rake war:compile # Compile rails code, and patch activesupport rake war:exploded # Create an exploded war in the app's public directory rake war:gems # Unpack all gems into WEB-INF/gems rake war:jar # Run the jar command to create the .war rake war:java_classes # Copy java classes into the .war rake war:java_libs # Copy all java libraries into the .war rake war:public # Copy all public HTML files to the root of the .war rake war:war:java_libs # Copy all java libraries into the .war rake war:webxml # Generate a web.xml file for the webapp 
   5. 如果你不是Rails2.3.2的話還需要修改C:/jruby-1.5.1/lib/ruby/gems/1.8/gems/warbler-1.1.0/lib/warbler/task.rb檔案
   6. def define_compile_task with_namespace_and_config do |name, config| desc "Compile rails code, and patch activesupport" task "compile" do # replace lib/active_support/dependencies.rb with patched version cp "#{File.dirname(__FILE__)}/dependencies-2.2.2.rb", "#{@config.staging_dir}/WEB-INF/gems/gems/activesupport-2.2.2/lib/active_support/dependencies.rb" # jrubyc all app file. Dir["#{@config.staging_dir}/WEB-INF/app/**/*.rb"].each do |file| rm file end sh "jrubyc app -t #{@config.staging_dir}/WEB-INF" end end end  
   7. 執行 > jruby -S warble war:aot
   8. 生成war包。並且裡面只有class
   9. 唐力群修改過的包提供了2.2.2/2.3.2兩個版本的dependencies.rb的修改。如果不是這兩個版本的rails，則需要自行修改dependencies.rb. 參考如下
