其实用Red Hat Enterprise Linux搭建Java开发环境也并不困难，在下列出几个步骤，供参考：
1、挂载光盘
[root@station25 ~]# mount /dev/cdrom /media/
mount: block device /dev/cdrom is write-protected, mounting read-only
2、配置yum源，并验证[rhel-debuginfo]
name=Red Hat
baseurl=file:///media/Server
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-RedHat-release
[root@station25 ~]# yum update Loaded plugins: rhnplugin, security This system is not registered with RHN. RHN support will be disabled. rhel-debuginfo | 1.3 kB 00:00 rhel-debuginfo/primary | 732 kB 00:00 rhel-debuginfo 2292/2292 Skipping security plugin, no data Setting up Update Process No Packages marked for Update
其实也主要就是这几个东西（当然还有一些依赖包啥的，总共133M）
java-1.6.0-openjdk.i386 1:1.6.0.0-1.2.b09.el5 rhel-debuginfo
java-1.6.0-openjdk-demo.i386 1:1.6.0.0-1.2.b09.el5 rhel-debuginfo
java-1.6.0-openjdk-devel.i386 1:1.6.0.0-1.2.b09.el5 rhel-debuginfo
java-1.6.0-openjdk-javadoc.i386 1:1.6.0.0-1.2.b09.el5 rhel-debuginfo
java-1.6.0-openjdk-src.i386 1:1.6.0.0-1.2.b09.el5 rhel-debuginfo
然后安装[root@station25 ~]# yum install java-* -y
Loaded plugins: rhnplugin, security
This system is not registered with RHN.
RHN support will be disabled.
