play framework学习笔记之 部署项目

Deployment options，部署的选择

1，

最简单和最健壮的项目部署方式是 without 容器

你可以把端口修改到80

You can use a frontal HTTP server like Lighttpd or Apache

当然你如果希望用到虚拟主机这样的功能，你也可以使用一些HTTP SERVER像apache，Lighttpd。让HTTP server转发。

2，部署在tomcat这样的servlet容器里面，支持tomcat6

需要打包成war

命令

play war myapp -o myapp.war

3，部署到GAE

安装play的GAE模块

play install gae

部署到GAE的命令

play gae:deploy myapp

项目部署的步骤

Set the framework in prod mode:

%production.application.mode=prod

Define a real database:

%production.db.url=jdbc:mysql://localhost/prod

%production.db.driver=com.mysql.jdbc.Driver

%production.db.user=root

%production.db.pass=1515312

Disable JPA automatic schema update:

%production.jpa.ddl=create

Define a secure secret key:

%production.application.secret=c12d1c59af499d20f4955d07255ed8ea333

log4j.rootLogger=ERROR, Rolling

log4j.logger.play=INFO

# Rolling files

log4j.appender.Rolling=org.apache.log4j.RollingFileAppender

log4j.appender.Rolling.File=application.log

log4j.appender.Rolling.MaxFileSize=1MB

log4j.appender.Rolling.MaxBackupIndex=100

log4j.appender.Rolling.layout=org.apache.log4j.PatternLayout

log4j.appender.Rolling.layout.ConversionPattern=%d{ABSOLUTE} %-5p ~ %m%n

%production.http.port=80

Set-up with lighttpd

This example shows you how to configurelighttpdas a front-end web server. Note that you can do the same with Apache, but if you only need virtual hosting or load balancing, lighttpd is a very good choice and much easier to configure!

The/etc/lighttpd/lighttpd.conffile should define things like this:

server.modules = (
      "mod_access",
      "mod_proxy",
      "mod_accesslog" 
)
...
$HTTP["host"] =~ "www.myapp.com" {
    proxy.balance = "round-robin" proxy.server = ( "/" =>
        ( ( "host" => "127.0.0.1", "port" => 9000 ) ) )
}
 
$HTTP["host"] =~ "www.loadbalancedapp.com" {
    proxy.balance = "round-robin" proxy.server = ( "/" => ( 
          ( "host" => "127.0.0.1", "port" => 9000 ), 
          ( "host" => "127.0.0.1", "port" => 9001 ) ) 
    )
}

Set-up with Apache

The example below shows a simple set-up withApache httpd serverrunning in front of a standard Play configuration.

LoadModule proxy_module modules/mod_proxy.so
...
<VirtualHost *:80>
  ProxyPreserveHost On
  ServerName www.loadbalancedapp.com
  ProxyPass / http://127.0.0.1:9000/
  ProxyPassReverse / http://127.0.0.1:9000/
</VirtualHost>

apache的其他配置，暂时 略去。
