回到監獄般的實驗室，用一台4年前的廢電腦，裝一個ubuntu來玩玩吧。

插播一段廣告頁面下載器(我的Java爬蟲之一)

https://segmentfault.com/a/1190000011881759Xpath、Jsoup、Xsoup(我的Java爬蟲之二)

問題1 ubuntu 14.04 --系統的網路服務與此版本的網路管理器不兼容問題

1
、sudo -s
2
、cd /etc/
NetworkManager
/
3
、ls -la
4
、mv system-connections /home/<username>/
#移動目錄到自己的用戶目錄下
5
、mkdir /system-connections
6
、reboot

當然，也可能是！32位的老機器，下載了64位的系統~~

問題2 銳捷上網問題

校園網下載客戶端後，

cd rjsupplicant
sudo ./rjsupplicant.sh -d
0
-u username -p password

此時如果網卡消失了

cd /etc/init.d/
sudo start network-manager

問題3 搭建ssh伺服器

sudo apt-
get
update
sudo apt-
get
install openssh-server

問題4 vim tab設置為四個空格

vim ~/.vimrc添加以下內容

set
ts=
4
set
expandtab

問題5 安裝java

以安裝 jdk-8u72-linux-x64.tar.gz 為例

#解壓安裝包：
sudo tar -zxvf jdk-
8u72
-linux-x64.tar.gz
mv jdk1.
8.0
_72
/ /
opt/
#配置環境變數：
#編輯配置文件：
sudo vim /etc/profile
#在該文件的最尾巴，添加下面內容：
JAVA_HOME=
/opt/
jdk1.
8.0
_72
JRE_HOME=$JAVA_HOME/jre
PATH=$PATH:$JAVA_HOME/bin
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export
JAVA_HOME
export
JRE_HOME
export
PATH
export
CLASSPATH
#執行命令，刷新該配置（必備操作）：
. /etc/profile
#檢查是否使用了最新的 JDK：
java -version

安裝maven

下載解壓完後，

vi~/.zshrc

export
M2_HOME=
/opt/
software/apache-maven-
3.5
.
0
export
M2=$M2_HOME/bin
export
PATH=$M2:$PATH

sublime中文輸入問題

解決方法：

#1. 進入sublime text3 插件管理文件夾
cd ~
/.config/
sublime-text-
3
/
Packages
#2. 獲取InputHelper插件
git clone https:
//github.com/xgenvn/InputHelper.git
#如果發現在sublime text3 中無法使用ctrl+shift+z調出輸入框，請檢查是否安裝pygtk
sudo apt-
get
install python-gtk2-dev

grub>

想給實驗室的這台小電腦挖坑，就保持

linux (hd0,
1
)/vmlinuz.efi root=
/dev/
sda3
initrd (hd0,
1
)/initrd.lz
boot

不然就試試

sudo update-grub
sudo grub-install /dev/sda

好用軟體系列

自己從廢舊電腦里淘到一個i5-3代的cpu，從一堆2G的內存里淘到兩個4G的，現在牛氣哄哄地升級系統，之前真的是，一把心酸淚

升級17.04

配置apt源，校園網，用清華的吧

sudo vi/etc/apt/sources.list

# 默認注釋了源碼鏡像以提高 apt update 速度，如有需要可自行取消注釋

升級！

升級17.04後沒有聲音

NVidia

The first step is to make sure that the GPU is not in use by a driver. As you"re using the nvidia driver, you must also be using prime.Run prime-select query.If it outputs nvidia, you can disable the driver by running sudo prime-select intel and rebooting.If it outputs unknown then the previous step might also work, but will also break your bumblebee setup.As a sanity check, make sure that the GPU and its audio chip are powered:Login as root: sudo suRun lspci -H1 | grep 01:00. It should output two lines.If the first line ends with (rev ff), you need to power your GPU by running echo ON > /proc/acpi/bbswitch.If the second line is missing, that means that the GPU audio chip is no longer powered. You can try suspending your laptop; resume it again; and check again whether the GPU audio chip is powered (I hope that works for you, otherwise you"re out of luck, like me).Run lsmod | grep nvidia again to make sure that the nvidia driver is still not in use.Now that the GPU is powered without a driver we"re going to "remove" it:Run echo 1 > /sys/bus/pci/devices/0000:01:00.0/remove (if the GPU still had a driver loaded/in use, this causes a kernel panic).Redetect the GPU and also its audio chip by running echo 1 > /sys/bus/pci/rescan.Run lspci | grep 01:00.1. If that outputs anything, congratulations! Your linux is now aware of your GPU audio chip.Get X running with the nvidia GPU.Run prime-select. If it outputs intel, run prime-select nvidia.Logout and back in again.If you run aplay -l now it should output the HDMI outputs (on my pc there are 4 outputs, and only 1 works).

安裝系統監控indicator-sysmonitor

sudo add-apt-repository ppa:fossfreedom/indicator-sysmonitor
sudo apt-
get
update
sudo apt-
get
install indicator-sysmonitor

最後在終端執行indicator-sysmonitor &即可

安裝zsh

之前竟然沒有放進來,裝oh my zsh的前提是要裝好了curl以及git

sudo apt-
get
install curl
sudo apt-
get
install git
sudo apt-
get
install zsh
sh -c
"$(curl -fsSL https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"
