Hardoop安装

1.安装jdk

apt-get install openjdk-7-jdk

错误一：

failed to fetch http //cn.archive.ubuntu.com

解决办法：

将下列文本添加到/etc/apt/sources.list文件里

deb http://mirrors.aliyun.com/ubuntu/ raring main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ raring-security main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ raring-updates main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ raring-proposed main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ raring-backports main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ raring main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ raring-security main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ raring-updates main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ raring-proposed main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ raring-backports main restricted universe multivers

但是执行sudo apt-get update仍然报错，问题在于DNS没有配置好。

解决方法：

sudovi /etc/resolv.conf

添加

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)

#    DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN

nameserver127.0.1.1

#这里用的是阿里云的DNS服务器

nameserver223.5.5.5

nameserver223.6.6.

之后执行sudo apt-get update就正常了。
