本文介绍soldat服务器和gefr WSGI适配器的环境搭建，以及jip的基本使用。

安装python工具

virtualenv和pip是python开发的关键工具
sudo apt-get install python-virtualenv
sudo apt-get install python-pip

jython需要您手动下载安装。推荐安装到/usr/local/下，并建立软连接到/usr/local/bin/中，下文将假设您是这么做的。

创建虚拟jython环境

virtualenv -p /usr/local/bin/jython gefr-test
cd gefr-test
source bin/activate

安装jip

pip install jip

配置jip

在$HOME下创建文件.jip，内容为：

[cc lang="ini"]
[repos:oss]
uri=http://oss.sonatype.org/content/repositories/snapshots/
type=remote

[repos:central]
uri=http://repo1.maven.org/maven2/
type=remote

[repos:local]
uri=/home/sun/.m2/repository/
type=local
[/cc]

安装soldat

配置完jip后，可以使用jip来安装soldat
jip install info.sunng.soldat:soldat:1.0-SNAPSHOT

文件将被下载到 javalib 目录中，您可以检查安装的正确性：
$ ls javalib/
log4j-1.2.16.jar slf4j-log4j12-1.6.1.jar
slf4j-api-1.6.1.jar soldat-1.0-SNAPSHOT.jar

安装gefr

pip install gefr==0.1dev2

创建一个简单的Python WSGI程序

创建test.py

[cc lang="python"]
from gefr import Gefr

def wsgiapp(environ, start_response):
status = '200 OK'
res_body = "Welcome

It works!

"
res_headers = [('Content-Type', 'text/html'),
('Content-Length', str(len(res_body)))]
start_response(status, res_headers)
return [res_body]

Gefr(wsgiapp, host='0.0.0.0', port=8000).start()
[/cc]

启动服务

使用jip附带的jython-all
jython-all test.py

打开浏览器，访问 http://localhost:8000/

用ab测试服务性能

$ ab -n 10000 -c 100 http://localhost:8000/
