linux-开发环境

一、开发环境

1)openjdk，http://www.sinoll.com/archives/652

java version "1.7.0_21"
OpenJDK Runtime Environment (IcedTea 2.3.9) (7u21-2.3.9-0ubuntu0.12.04.1)
OpenJDK Server VM (build 23.7-b01, mixed mode)

2)maven3：最好把环境变量设置在/etc/profile，虽然网上说/etc/profile或者/etc/environment都可以，但是设置后者实践证明会导致进入不了系统，最后ctrl+alt+f1进入命令行删掉变量才解决

mvn --version
Apache Maven 3.0.5 (r01de14724cdef164cd33c7c8c2fe155faf9602da; 2013-02-19 21:51:28+0800)
Maven home: /usr/local/maven3
Java version: 1.7.0_21, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-7-openjdk-i386/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.5.0-28-generic", arch: "i386", family: "unix"

3）jetty，http://www.eclipse.org/jetty/，http://www.eclipse.org/jetty/documentation/current/

4) 设置命令别名

用户目录创建空文件：touch .bash_profile

编辑：open .bash_profile 

输入：比如，alias ll='ls -la'

立即生效执行：source .bash_profile
