简介<!---->1. <!---->ubuntu版本：ubuntu-12.04-server-i386.iso
安装SSH
安装命令如下，安装过程过于简单就不用说了。
sudo apt-get install openssh-server
查看是否安装成功：
ps -e |grep ssh
1329 ? 00:00:00 sshd
看到sshd那说明ssh-server已经启动了
查看IP：ifconfig
naxsu@ubuntu:~$ ifconfig

安装jdk
<!---->1. <!---->下载
wgethttp://download.oracle.com/otn-pub/java/jdk/6u31-b04/jdk-6u31-linux-i586.bin
<!---->2. <!---->把jdk移到/usr/local/目录下
naxsu@ubuntu:~$sudo mv jdk-6u31-linux-i586.bin /usr/local/
password for naxsu:
<!---->3. <!---->安装
naxsu@ubuntu:/usr/local$./jdk-6u31-linux-i586.bin
-bash:./jdk-6u31-linux-i586.bin: Permission denied
提示没权限
方法一：在前面加上sudo sh
root@ubuntu:/usr/java#sudosh ./ jdk-6u31-linux-i586.bin
方法二：加权限
root@ubuntu:/usr/java#sudo chmod u+x jdk-6u31-linux-i586.bin
root@ubuntu:/usr/java#./ jdk-6u31-linux-i586.bin
naxsu@ubuntu:/usr/local$sudo chmod u+x jdk-6u31-linux-i586.bin
naxsu@ubuntu:/usr/local$sudo ./jdk-6u31-linux-i586.bin
出问题了，如下：

用vi编辑器打开，竟是一个网页。
只能到官网下载JDK了，下节续
