karaf是OSGI的容器实例，类似tomcat是servlet的容器实例一样
官网：http://karaf.apache.org
1，下载源文件
在http://karaf.apache.org/index/community/download.html
下载apache-karaf-2.3.0.zip, apache-karaf-2.3.0-src.zip
2，解压
解压apache-karaf-2.3.0.zip,比如到E:\workspace\apache-karaf-2.3.0
解压apache-karaf-2.3.0-src.zip并把src目录移动到E:\workspace\apache-karaf-2.3.0
目录结构为：
/bin: startup scripts
/data: working directory
/demos:
/deploy: hot deploy directory
/etc: configuration files
/lib: contains the bootstrap libraries
/src: unzip from apache-karaf-2.3.0-src.zip
/system: OSGi bundles repository, laid out as a Maven 2 repository
/instances: directory containing child instances //mvn 成功后，会创建此目录
/cache: OSGi framework bundle cache
/generated-bundles: temporary folder used by the deployer
/log: log files
/deploy: hot deploy directory
/instances: directory containing child instances
/lib: contains the bootstrap libraries
/lib/ext: directory for JRE extensions
/lib/endorsed: directory for endorsed libraries
/system: OSGi bundles repository, laid out as a Maven 2 repository
3，执行mvn命令
E:\workspace\apache-karaf-2.3.0\src>mvn clean install -DskipTests=true
出现karaf@root时就证明成功了，如果卡死，可以任务管理器关掉2个java.exe
4，启动karaf
然后进入E:\workspace\apache-karaf-2.3.0\bin>karaf//会启动2个java.exe
验证：下面是成功的输出
karaf@root> admin:list
SSH Port RMI Ports State Pid Name
[ 8101] [1099/44444 ] [Started ] [ 2704] root
5, Managing child instances
admin:create alpha//创建子实例
会建立apache-karaf-2.3.0\instances\alpha目录，并有子目录：bin,data,deploy,etc,system
admin:list//LISTING ALL container instances
//连接child instance, 需要再打开一个cmd,启动子实例
admin:connect [-u username] [-p password] instance //CONNECTING TO A CHILD INSTANCE
logout//退出连接
admin:stop instance
admin:destroy instance
6, 关闭Karaf : osgi:shutdown.
更多命令可以用帮助命令，--help，或者cmd提示。
