简介

<!--[if !supportLists]-->1.       <!--[endif]-->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

用SecureCRT连接

安装jdk

<!--[if !supportLists]-->1.       <!--[endif]-->下载

wget http://download.oracle.com/otn-pub/java/jdk/6u31-b04/jdk-6u31-linux-i586.bin

<!--[if !supportLists]-->2.       <!--[endif]-->把jdk移到/usr/local/目录下

naxsu@ubuntu:~$ sudo mv jdk-6u31-linux-i586.bin /usr/local/

[sudo] password for naxsu:

<!--[if !supportLists]-->3.       <!--[endif]-->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#sudo sh ./ 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：

naxsu@ubuntu:/usr/local$ sudo ./jdk-6u31-linux-i586.bin

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
