簡(jiǎn)介
1. ubuntu版本：ubuntu-12.04-server-i386.iso
安裝SSH
安裝命令如下，安裝過(guò)程過(guò)于簡(jiǎn)單就不用說(shuō)了。
sudo apt-get install openssh-server
查看是否安裝成功：
ps -e |grep ssh
看到sshd那說(shuō)明ssh-server已經(jīng)啟動(dòng)了
查看IP：ifconfig
| naxsu@ubuntu:~$ ifconfig eth0 Link encap:Ethernet HWaddr 00:0c:29:e0:32:e5 inet addr:192.168.26.128 Bcast:192.168.26.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fee0:32e5/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:53 errors:0 dropped:0 overruns:0 frame:0 TX packets:55 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:5999 (5.9 KB) TX bytes:7364 (7.3 KB) Interrupt:19 Base address:0x2000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) |
用SecureCRT連接
安裝jdk
1. 下載
wget http://download.oracle.com/otn-pub/java/jdk/6u31-b04/jdk-6u31-linux-i586.bin
2. 把jdk移到/usr/local/目錄下
naxsu@ubuntu:~$ sudo mv jdk-6u31-linux-i586.bin /usr/local/
[sudo] password for naxsu:
3. 安裝
naxsu@ubuntu:/usr/local$ ./jdk-6u31-linux-i586.bin
-bash: ./jdk-6u31-linux-i586.bin: Permission denied
提示沒(méi)權(quán)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：加權(quán)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
出問(wèn)題了，如下：

用vi編輯器打開(kāi)，竟是一個(gè)網(wǎng)頁(yè)。
只能到官網(wǎng)下載JDK了
用VMware Workstation虛擬機(jī)來(lái)識(shí)別USB設(shè)備(如U盤(pán))的方法
首先，要使VM虛擬機(jī)能夠識(shí)別USB設(shè)備，也就像Windows中的找到新硬件提示一樣，打開(kāi)虛擬機(jī)，運(yùn)行后，插入USB設(shè)備（該設(shè)備已被Windows識(shí)別），然后按照?qǐng)D示方式選擇Removable Devices,選擇USB Device，然后在VM的右下角會(huì)出現(xiàn)USB設(shè)備圖標(biāo)，證明已經(jīng)被VM識(shí)別出來(lái)了。
其次，因?yàn)樵?/span>Linux系統(tǒng)中要讀取U盤(pán)設(shè)備，必須通過(guò)文件掛載的方式來(lái)訪問(wèn)，即把USB設(shè)備也當(dāng)成文件來(lái)訪問(wèn)，要掛載設(shè)備，首先要知道其設(shè)備名，然后在利用掛載命令掛載，可以用fdisk –l或者dmesg命令獲得USB設(shè)備的設(shè)備名假設(shè)為sdb1，然后新建一個(gè)文件夾目錄比如mkdir myusb ,再利用mount –t –vfat 設(shè)備名 掛載目錄命令掛載，這里可使用mount –t –vfat sdb1 myusb，然后就可以通過(guò)myusb目錄訪問(wèn)USB設(shè)備上的內(nèi)容。
最后，使用完畢之后要卸載USB，可以使用unmount掛載目錄，或者unmount 設(shè)備名，即可使用unmount myusb或者unmount sdb1來(lái)卸載。

配置環(huán)境變量
用vim編輯，沒(méi)有就安裝
| naxsu@ubuntu:/usr/local/jdk1.6.0_24$ vim /etc/profile The program 'vim' can be found in the following packages: * vim * vim-gnome * vim-tiny * vim-athena * vim-gtk * vim-nox Try: sudo apt-get install <selected package> naxsu@ubuntu:/usr/local/jdk1.6.0_24$ sudo apt-get install vim naxsu@ubuntu:/usr/local$ sudo vim /etc/profile 加入以下代碼： #set java environment export JAVA_HOME= /usr/local/jdk1.6.0_24 export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH:$HOMR/bin 下面才有效 export JAVA_HOME=/usr/local/jdk1.6.0_24 export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$JAVA_HOME/bin:$PATH |
每次都用sudo太麻煩了，我們來(lái)激活root用戶
naxsu@ubuntu:/usr/local$ sudo -s
root@ubuntu:/usr/local#
修改root用戶密碼
在終端執(zhí)行 sudo passwd root 指令后，系統(tǒng)將會(huì)提示你設(shè)置一個(gè)新的 root 帳號(hào)密碼
如果要禁用 root 帳號(hào)，那么可以執(zhí)行 sudo passwd -l root
/etc/profile的設(shè)置對(duì)su root無(wú)效
| 那如何將/etc/profile的設(shè)置在su root也能生效呢？ naxsu@ubuntu:~$ su - root Password: “-”不能省略，它是–login的編寫(xiě)。 |
| 讓當(dāng)前配置立即生效 root@ubuntu:~# source /etc/profile 測(cè)試安裝是否成功 root@ubuntu:~# echo $JAVA_HOME /usr/local/jdk1.6.0_24 root@ubuntu:~# echo $PATH /usr/local/jdk1.6.0_24/bin:/bin:/jre/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/bin root@ubuntu:~# echo $CLASSPATH .:/usr/local/jdk1.6.0_24/lib/dt.jar:/usr/local/jdk1.6.0_24/lib/tools.jar root@ubuntu:~# java -version java version "1.6.0_24" Java(TM) SE Runtime Environment (build 1.6.0_24-b07) Java HotSpot(TM) Client VM (build 19.1-b02, mixed mode, sharing) root@ubuntu:~# 以上提示說(shuō)明安裝成功。 |
