CentOS5.3_JSP服务器_03 安装 wget jdk1.7.0 和设置环境变量

2009-05-14  分类：centos5.3_jsp 标签: , ,  作者:fanzg


今天为 centos 5.3 服务器安装jdk, 如果你要开发，运行 java 程序，jdk 是必不可少的。

如果不开发，也就是不用编译java程序，那么只安装jre就可以了。

我这里进行 JDK 安装， 目前为止 jdk 1.7 版本为最新版本吧，1.5 叫做jdk5.0

我不知道 jdk1.7 是否叫做 jdk 7.0 呵呵。

下载站点：

http://download.java.net/jdk7/binaries/

Linux Platform
 Linux RPM in self-extracting JDK file
 jdk-7-ea-bin-b58-linux-i586-08_may_2009-rpm.bin, 59.64 MB

由于文件比较大，我就不提供下载了，

http://www.java.net/download/jdk7/binaries/jdk-7-ea-bin-b58-linux-i586-08_may_2009-rpm.bin
这个就是完整的下载路径，

如果路径更新不能用了，建议去

http://download.java.net/jdk7/binaries/   重新找到对应的文件下载。

我已经下载好了，下面传送到 Linux 上面去。
我xp系统是 192.168.1.5
所以 wget http://192.168.1.5:2000/jdk-7-ea-bin-b58-linux-i586-08_may_2009-rpm.bin

比较郁闷一件事， CentOS5.3没有 wget 这个工具，看来要自己安装了。

]# yum -y install wget

好了，安装好了 wget 我们继续

wget http://192.168.1.5:2000/jdk-7-ea-bin-b58-linux-i586-08_may_2009-rpm.bin

 ]# gcc -v  检查是否存在gcc
 ]# rpm -qa | grep yacc 检查 yacc 有没有装

 ]# chmod +x jdk-7-ea-bin-b58-linux-i586-08_may_2009-rpm.bin

 ]# ./jdk-7-ea-bin-b58-linux-i586-08_may_2009-rpm.bin

最后输入  yes 进行安装 ， 由于我刚才复制文本了出现问题，重新安装。

Done.

安装完毕。

[root@localhost usr]# ls /usr/java/
default  jdk1.7.0  latest

看到了吧。

配置 java 环境参数

 ]# vi ~/.bash_profile  修改成这样

  JAVA_HOME=/usr/java/jdk1.7.0
  CLASSPATH=.:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar
  PATH=$PATH:$HOME/bin:$JAVA_HOME/bin:$JAVA_HOME/jre/bin

  export PATH JAVA_HOME CLASSPATH

保存退出，如果输入 java 和 javac 可以正常运行就可以了。

下面编写一个 HelloWorld.java 文件 进行测试，呵呵。很久没有写过 java 程序了。

public class HelloWorld
{
        public static  void main( String args[] )
        {
                System.out.println( "HelloWorld!!" );
        }

}

[root@localhost /]# vi HelloWorld.java
[root@localhost /]# javac HelloWorld.java
[root@localhost /]# java HelloWorld
HelloWorld - www.17rumen.com

注意使用 rm -rf 命令，看清楚目录。
[root@localhost opt]# rm -rf *

一切正常， 清空刚才没用的文件。。。

好了 ，今天演示到这里，谢谢大家观看！！！！

    我在用你的方法安装jdk时您提供的下载地址已经失效了，我下载了新版本的jdk，但是用你的命令之后会出现错误。
    # chmod +x jdk-7-ea-bin-b58-linux-i586-08_may_2009-rpm.bin

    # ./jdk-7-ea-bin-b58-linux-i586-08_may_2009-rpm.bin

    Do you agree to the above license terms? [yes or no]
    当我输入yes后就进行不下去了，所以我在后面又加了条命令
    rpm -ivh jdk-7-ea-linux-i586.rpm就可以进行了！

    楼主您好，我碰到了

    java /opt/HelloWorld.java

    Error: Could not find main class .opt.HelloWorld.java
    Exception in thread "main" java.lang.NoClassDefFoundError: .opt.HelloWorld.java
    at sun.launcher.LauncherHelper.checkAndLoadMain(LauncherHelper.java:198)

    求问是为什么呢？

    java /opt/HelloWorld 不用 .java

    如果是 javac 则如下 :

    javac /opt/helloWorld.java
