Ubuntu下搭建sun-jdk和Maven2

环境描述:Ubuntu Server 12.04 / java-6-sun-1.6.0.06 / apache-maven-3.0.4

1、安装sun-jdk

因为sun-jdk被oracle收购了,所以Ubuntu支持开源,目前已经没有oracle java jdk新版本的更新源了,所以要安装sun-jdk,只能安装老版本,而且必须要更新Ubuntu的下载源,如下:

需要安装

>> apt-get install python-software-properties

将sun-6-jre的下载源更新到sources.list中
>> add-apt-repository "deb http://us.archive.ubuntu.com/ubuntu/ hardy multiverse"

然后就可以通过命令行直接安装了,安装之前需要更新列表apt-get update

>> apt-get install sun-java6-jdk

通常情况下,Ubuntu server会默认选择安装openjdk,所以这里我们要更改jdk的优先级以及指令链接如下:

>> update-alternatives --install /usr/bin/java java /usr/lib/jvm/java-6-sun-1.6.0.06/bin/java 300

>> update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/java-6-sun-1.6.0.06/bin/javac 300

接着修改默认的JDK

>> sudo update-alternatives --config java,如下选择默认使用的jdk

There are 3 choices for the alternative java (providing /usr/bin/java).

  Selection    Path                                            Priority   Status
------------------------------------------------------------
  0            /usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java   1061      auto mode
  1            /usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java   1061      manual mode
* 2            /usr/lib/jvm/java-6-sun-1.6.0.06/bin/java        300       manual mode
  3            /usr/lib/jvm/java-6-sun/jre/bin/java             63        manual mode

Press enter to keep the current choice[*], or type selection number: 这里选择 2 即可

至此,sun-jdk被默认安装在了/usr/lib/jvm/java-6-sun-1.6.0.06

2、安装maven2

http://maven.apache.org/去下载maven的最新版本,当前是apache-maven-3.0.4,包选择apache-maven-3.0.4-bin.tar.gz

将apache-maven-3.0.4-bin.tar.gz上传到/usr/share目录下,通过如下命令解压

>> tar -zxvf apache-maven-3.0.4-bin.tar.gz 至 /usr/share/apache-maven-3.0.4

至此maven的安装完成

3、配置Java和maven的环境变量

>> vi /etc/environment

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:$JAVA_HOME/bin:$MAVEN_HOME/bin"
JAVA_HOME=/usr/lib/jvm/java-6-sun-1.6.0.06
CLASSPATH=.:$JAVA_HOME/lib
MAVEN_HOME=/usr/share/apache-maven-3.0.4
export JAVA_HOME
export MAVEN_HOME
export CLASSPATH
export PATH

此处的PATH:$JAVA_HOME/bin:$MAVEN_HOME/bin,可以单独作为一行单列也可以。

保存之后,重新其中环境变量使之生效

>>source /etc/environment

4、检测Java和maven配置是否成功

>> java -version
java version "1.6.0_06"
Java(TM) SE Runtime Environment (build 1.6.0_06-b02)
Java HotSpot(TM) 64-Bit Server VM (build 10.0-b22, mixed mode)

>> mvn -version
Apache Maven 3.0.4 (r1232337; 2012-01-17 08:44:56+0000)
Maven home: /usr/share/apache-maven-3.0.4
Java version: 1.6.0_06, vendor: Sun Microsystems Inc.
Java home: /usr/lib/jvm/java-6-sun-1.6.0.06/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.2.0-24-virtual", arch: "amd64", family: "unix"

到此表示Java和Maven的环境配置成功!
