个人面试准备过程--ubuntu使用过程记录

回到监狱般的实验室，用一台4年前的废电脑，装一个ubuntu来玩玩吧。

问题1 ubuntu 14.04 --系统的网络服务与此版本的网络管理器不兼容问题

一、sudo -s 
二、cd /etc/NetworkManager/
三、ls -la
四、mv system-connections /home/<username>/   #移动目录到本身的用户目录下
五、mkdir /system-connections         
六、reboot

固然，也多是！32位的老机器，下载了64位的系统~~

问题2. 锐捷上网问题

校园网下载客户端后，

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

此时若是网卡消失了

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

问题3. 搭建ssh服务器

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

问题4. vim tab设置为四个空格

vim ~/.vimrc
添加如下内容

set ts=4
set expandtab

问题5. 安装java

以安装 jdk-8u72-linux-x64.tar.gz 为例

#解压安装包：
sudo tar -zxvf jdk-8u72-linux-x64.tar.gz
mv jdk1.8.0_72/ /opt/
#配置环境变量：
#编辑配置文件：
sudo vim /etc/profile
#在该文件的最尾巴，添加下面内容：
  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
#执行命令，刷新该配置（必备操做）：
. /etc/profile
#检查是否使用了最新的 JDK：
java -version

安装maven

下载解压完后，vi ~/.zshrc

export M2_HOME=/opt/software/apache-maven-3.5.0
export M2=$M2_HOME/bin
export PATH=$M2:$PATH

sublime中文输入问题

解决方法：
#1. 进入sublime text3 插件管理文件夹
cd ~/.config/sublime-text-3/Packages

#2. 获取InputHelper插件
git clone https://github.com/xgenvn/InputHelper.git

#若是发如今sublime text3 中没法使用ctrl+shift+z调出输入框，请检查是否安装pygtk
sudo apt-get install python-gtk2-dev

grub>

想给实验室的这台小电脑挖坑，就保持

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

否则就试试

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

好用软件系列

安装Albert 和 Casio

sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install albert
sudo apt-get install cairo-dock

开发者相关

安装zeal

sudo apt-get install zeal

本身从废旧电脑里淘到一个i5-3代的cpu，从一堆2G的内存里淘到两个4G的，如今牛气哄哄地升级系统，以前真的是，一把心酸泪

升级17.04

配置apt源，校园网，用清华的吧

sudo vi /etc/apt/sources.list

# 默认注释了源码镜像以提升 apt update 速度，若有须要可自行取消注释
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial main restricted universe multiverse

升级！

sudo do-release-upgrade -d

升级17.04后没有声音

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).

安装系统监控indicator-sysmonitor

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

最后在终端执行indicator-sysmonitor &便可

安装zsh

以前居然没有放进来,装oh my zsh的前提是要装好了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)"
