这里说下关于在Ubuntu Server 14.04 LTS（64bit）下安装weblogic Server 12c（12.1.3） Zip Distribution遇到的问题。至于Windows环境下的安装没什么好说的，只要你根据wls1213_dev.zip中自带的README.TXT一步步做，是不会出现问题的。但是对于在一个干净的Ubuntu Server下的来说，根据向导的说明你是装不起来的。因为它缺少了必要的环境设置，也许这对于linux下的老手来说这些都不是事。
当在安装中遇到问题时，如果询问百度，你会所搜到很多安装教程（大部分是Windows环境）。个别安装向导中还会提到两个环境变量的设置，这两个变量在安装目录下的README.txt中不曾提到，这两个是：
1. JAVA_VENDOR=Sun
2. CONFIG_JVM_ARGS=-Djava.security.egd=file:/dev/./urandom
其中 JAVA_VENDOR=Sun 从weblogic Server 12c（12.1.2）之后应该是不需要再设置了。而CONFIG_JVM_ARGS=-Djava.security.egd=file:/dev/./urandom是针对Linux环境的。但是在Ubuntu 都不起作用。真不知道，倒是Weblogic的问题，还是Ubuntu自身的问题。
在给出我的安装步骤之前，给各位再提供篇Oracle官方关于Weblogic
12c ZIP的安装指导，在Ubuntu下没指导意义。
下面我们步入正题。
准备工作
1.你需要为你的Ubuntu安装好JDK，并设置好环境变量。至于如何去做，这里不再细说，不会的同学请自己谷歌或百度。
2、从Oralce官网下载最新的Weblogic 12c （当前文档编写时的最新版本是Weblogic 12c（12.1.3））。
安装步骤
1、将下载的wls1213_dev.zip 解要到home下，名为wls12130。
[plain] view
plain copy
- unzip wls1213_dev.zip
- mv wls12130 ~
2、安装
[plain] view
plain copy
- cd ~/wls12130
- export MW_HOME=/home/zhaojh/wls12130/
- export JAVA_OPTIONS="-Djava.security.egd=file:/dev/./urandom"
- ./configure.sh
输出
[plain] view
plain copy

注意上面输出信息最后那个 “Do you want to configure
a new domain?” 时选择n
3、配置一个新域
[plain] view
plain copy
- . $MW_HOME/wlserver/server/bin/setWLSEnv.sh
- mkdir -p user_projects/domains/mydomain
- cd user_projects/domains/mydomain
- java $JAVA_OPTIONS -Xmx1024m -XX:MaxPermSize=256m weblogic.Server
输出内容

总结
在Ubuntu Server下安装Weblogic 12c （12.1.3）时，除了按照安装说明（安装目录下README.txt中）做之外，还需要注意两点：
1、在开始安装前不要忘了在设置MW_HOME的同时设置 JAVA_OPTIONS="-Djava.security.egd=file:/dev/./urandom" 。
2、在执行./configure.sh 时，在显示“Do you want to configure a new domain? [y/n]? ”时选择 “n”。
