Linux环境下的持续集成之安装配置JDK

1、下载JDK：jdk-6u24-linux-i586-rpm.bin

，过程不表

 

2、安装:

把下载到桌面的jdk-6u24-linux-i586-rpm.bin 复制到/usr/local/jdk1.6，其中jdk1.6目录默认是没有的，需要自己建立

[root@localhost ~]# pwd
/root
[root@localhost ~]# ls
anaconda-ks.cfg  Desktop  install.log  install.log.syslog
[root@localhost ~]# cd  Desktop/
[root@localhost Desktop]# ls
jdk-6u24-linux-i586-rpm.bin
[root@localhost Desktop]# cp jdk-6u24-linux-i586-rpm.bin  /usr/local/jdk1.6

[root@localhost Desktop]# cd /usr/local/jdk1.6

[root@localhost jdk1.6]# ls
jdk-6u24-linux-i586-rpm.bin

赋予可执行权限
[root@localhost jdk1.6]# chmod a+x jdk-6u24-linux-i586-rpm.bin

解压

[root@localhost jdk1.6]# ./jdk-6u24-linux-i586-rpm.bin

Java(TM) SE Development Kit 6 successfully installed.

Product Registration is FREE and includes many benefits:
* Notification of new versions, patches, and updates
* Special offers on Oracle products, services and training
* Access to early releases and documentation

Product and system data will be collected. If your configuration
supports a browser, the JDK Product Registration form will
be presented. If you do not register, none of this information
will be saved. You may also register your JDK later by
opening the register.html file (located in the JDK installation
directory) in a browser.

For more information on what data Registration collects and
how it is managed and used, see:

# vi /etc/profile
在最后加入以下几行：
export JAVA_HOME=/usr/local/java/jdk1.6.0_18
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin
用reboot命令重启

 

4、测试

新建目录javasrc,

 

创建源文件jahelloworld.java，

 

public class helloworld{
　　public static void main(String[] args){
　　System.out.println("Hello,Welcome to Linux World!");
　　}
　　}

[root@localhost javasrc]# javac helloworld.java

[root@localhost javasrc]# java helloworld
hello,world.

ok,成功.
