新安装的Ubuntu安装jdk失败，解决方法

标签：ubuntu安装java环境

刚刚从阿里云租用了一台服务器准备着手按照hadoop，前提条件是安装java环境

在安装jdk时发现，报如下错误

The program ‘java‘ can be found in the following packages:
* gcj-4.4-jre-headless
* gcj-4.6-jre-headless
* openjdk-6-jre-headless
* gcj-4.5-jre-headless
* openjdk-7-jre-headless

查了查资料，发现需要更新下agt命令：apt-get update一定要更新下agt否则会执行失败

在执行 apt-get install openjdk-7-jre openjdk-7-jdk  下载安装

输入javac出现如下提示说明安装成功了
