# 1、JDK #

1.1下载JDK：[http://download.oracle.com/otn-pub/java/jdk/7/jdk-7-linux-i586.tar.gz][http_download.oracle.com_otn-pub_java_jdk_7_jdk-7-linux-i586.tar.gz]（下载默认路劲为主目录中的下载文件夹，下同）

(下载链接:http://pan.baidu.com/share/link?shareid=3125558486&uk=1228060797 密码:aily)

1.2 解压

$cd 下载

$tar jdk-7-linux-i586.tar.gz

1.3 将解压后的jdk1.7.0移到/usr/local/目录下

$sudo mv jdk1.7.0 /usr/local/

1.4 配置环境

$sudo gedit /etc/environment

将内容改为：

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/jdk1.7.0/bin"

CLASSPATH=.:/usr/local/jdk1.7.0/lib

JAVA\_HOME=/usr/local/jdk1.7.0

1.5 运行$source ~/.bashrc

1.6 测试$java -version

如果查询不到版本号，说明还没安装成功，那么再执行以下语句：

$sudoupdate-alternatives --install /usr/bin/java java /usr/local/jdk1.7.0/bin/java 300

$sudo update-alternatives --install /usr/bin/javac javac /usr/local/jdk1.7.0/bin/javac 300

$sudo update-alternatives --install /usr/bin/javap javap /usr/local/jdk1.7.0/bin/javap 300

$sudo update-alternatives --install /usr/bin/javadoc javadoc /usr/local/jdk1.7.0/bin/javadoc 300

再次测试，则可以看到版本号了。

$tar zxvf eclipse-jee-juno-SR2-linux-gtk.tar.gz

2.3 将解压后的eclipse移到/usr/local/目录下

$sudo mv eclipse /usr/local/
