呵呵。搞了好几天，今晚终于把MYECLIPSE装上了。呵呵
方法如下：
1、使用源光盘安装ECLIPSE3。2。0。
2、使用vi /usr/bin/eclipse.将所有的MOZILLA_FIVE_HOME=之后的内容注释掉。然后加入：export MOZILLA_FIVE_HOME="",就可以了。我的/usr/bin/eclipse如下：
#!/bin/bash
# Having any sort of classpath causes massive breakage, with Kaffe at least.
unset CLASSPATH; export CLASSPATH
# Allow the user to specify their own Java home, we check for it later.
#unset JAVA_HOME; export JAVA_HOME

3、启动ECLIPSE然后进行升级，需要升级到3。2。2，因为MYECLIPSE5。5。1GA好像必须要在3。2。2下才你能跑起来。
4、安装JDK1。6。0_13，然后将/sur/bin/eclipse中的JAVA_HOME及CLASSPATH环境变量进行修改，因为我的JDK1。6。0_13安装在/usr/lib/eclipse/jdk1.6.0_13,所以我的以上两个环境变量配好了就是如下的内容：
unset JAVA_HOME; export JAVA_HOME=/usr/lib/eclipse/jdk1.6.0_13
unset CLASSPATH; export CLASSPATH=/usr/lib/eclipse/jdk1.6.0_13/jre/lib
5、去下载MyEclipse_5.5.1GA_UpdateSite.zip文件（其实就是离线升级包）
6、重启ECLIPSE，并在帮助－》软件更新－》中进行离线升级。
7、重启之后如果过程顺利就因该在主菜单中看到MYECLIPSE选项了。如图：
这是使用的MyEclipse Database Explorer,可以方便的连接ORACLE MYSQL SYBASE等数据库，并进行SQL语句操作。呵呵很方便的。
