個人面試準備過程--ubuntu使用過程記錄

回到監獄般的實驗室，用一臺4年前的廢電腦，裝一個ubuntu來玩玩吧。

問題1 ubuntu 14.04 --系統的網絡服務與此版本的網絡管理器不兼容問題

一、sudo -s 
二、cd /etc/NetworkManager/
三、ls -la
四、mv system-connections /home/<username>/   #移動目錄到本身的用戶目錄下
五、mkdir /system-connections         
六、reboot

固然，也多是！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

此時若是網卡消失了

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

問題3. 搭建ssh服務器

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

問題4. vim tab設置爲四個空格

vim ~/.vimrc
添加如下內容

set ts=4
set expandtab

問題5. 安裝java

以安裝 jdk-8u72-linux-x64.tar.gz 爲例

#解壓安裝包：
sudo tar -zxvf jdk-8u72-linux-x64.tar.gz
mv jdk1.8.0_72/ /opt/
#配置環境變量：
#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（必備操做）：
. /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

#若是發如今sublime text3 中沒法使用ctrl+shift+z調出輸入框，請檢查是否安裝pygtk
sudo apt-get install python-gtk2-dev

grub>

想給實驗室的這臺小電腦挖坑，就保持

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

否則就試試

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

好用軟件系列

安裝zeal

sudo apt-get install zeal

本身從廢舊電腦裏淘到一個i5-3代的cpu，從一堆2G的內存裏淘到兩個4G的，如今牛氣哄哄地升級系統，以前真的是，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

# 默認註釋了源碼鏡像以提升 apt update 速度，若有須要可自行取消註釋

升級！

sudo do-release-upgrade -d

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 su
Run 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 &便可

安裝zsh

以前居然沒有放進來,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)"
