搭建Centos 7 实验环境
环境
- VMware workstation 15 pro； Centos 7
- 镜像 ：CentOS-7-x86_64-DVD-1908.iso 觉得麻烦的可以使用后面的这个地址：[https://mirror.umd.edu/centos/7/isos/x86_64/CentOS-7-x86_64-DVD-1908.iso](下载地址)
>> - **最好别使用LiveGNOME环境**，部分机器每次重启都需要重新设置 语言 以及其他部分选项，很麻烦。
- Windows 10 1909版本 os 内部版本 1836.836
>> - 查看版本方式： 按下windows 同时按 R ，在输入框中输入winver 按回车 会弹出 Windows 系统的信息
安装步骤
1. 下载VMware 并安装，具体教程百度下，很多。简述下
>> >> 1. 官网下载安装包，[https://my.vmware.com/en/web/vmware/info/slug/desktop_end_user_computing/vmware_workstation_pro/15_0](下载地址) 选择 你当前电脑 操作系统 种类对应的安装包
>> 2. Windows 下，直接双击安装包，简易安装就直接一路next就好。记得看到分配硬盘空间的时候 分配稍大的空间，后续 扩展空间相对麻烦，可以自行百度下。
2. 下载centos 7镜像（上面给出下载地址了）
3. 在安装好的VMware workstation pro 中选择虚拟机安装，一路next就好。
4. 在点击完成后，会进入界面。选择 install centos
搭建环境
1. 进入Linux（Centos 7）环境下，点击右上角 电源按钮，在有线连接（即使你自己电脑（宿主机）使用的是WiFi，Linux中也会显示有线连接，这是VMware workstation pro软件本身设计好的））处点击连接。不点的话可能在运行下边命令的时候提示你没联网。
2. 运行命令
>> 安装zsh（shell的一种）
>> `sudo su`
>> 然后输入你在安装系统时设置好的密码
>> `yum install zsh`
>> 更换Centos 7源（所谓 源 就是一个公共库，用户centos 7进行相关插件 软件的更新及安装）
>> 先备份系统初始 源
>> cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak
>> 更改源
>> `gedit /etc/yum.repos.d/CentOS-Base.repo`
>> ctrl + a选中文件中所有内容将下边代码复制进去，保存。

#The mirror system uses the connecting IP address of the client and the
#update status of each mirror to pick mirrors that are updated to and
#geographically close to the client. You should use this for CentOS updates
#unless you are manually picking other mirrors.
#If the mirrorlist= does not work for you, as a fall back you can try the
#remarked out baseurl= line instead.

yum upgrade
gedit install.sh
在弹出的界面中复制粘贴下列内容（用于下载安装oh-my-zsh —— 一种用于美化zsh shell 的插件，由于该插件被墙了，给出安装所需的bash文件代码）
`#!/bin/sh
#This script should be run via curl:
#sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
#or wget:
#sh -c "$(wget -qO- https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
#As an alternative, you can first download the install script and run it afterwards:
#wget https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh
#sh install.sh
#You can tweak the install behavior by setting variables when running the script. For
#example, to change the path to the Oh My Zsh repository:
#ZSH=~/.zsh sh install.sh
#
#Respects the following environment variables:
# ZSH - path to the Oh My Zsh repository folder (default: $HOME/.oh-my-zsh)
# REPO - name of the GitHub repo to install from (default: ohmyzsh/ohmyzsh)
# REMOTE - full remote URL of the git repo to install (default: GitHub via HTTPS)
# BRANCH - branch to check out immediately after install (default: master)
#
# Other options:
# CHSH - 'no' means the installer will not change the default shell (default: yes)
# RUNZSH - 'no' means the installer will not run zsh after the install (default: yes)
# KEEP_ZSHRC - 'yes' means the installer will not replace an existing .zshrc (default: no)
#
# You can also pass some arguments to the install script to set some these options:
# --skip-chsh: has the same behavior as setting CHSH to 'no'
# --unattended: sets both CHSH and RUNZSH to 'no'
# --keep-zshrc: sets KEEP_ZSHRC to 'yes'
# For example:
# sh install.sh --unattended
#

然后等待安装
安装好后
安装vscode IDE 因为之前Windows 中使用vscode挺方便的就安装了这个。
安装链接
rpm --import https://packages.microsoft.com/keys/microsoft.asc
sh -c 'echo -e "[code]
name=Visual Studio Code
baseurl=https://packages.microsoft.com/yumrepos/vscode
enabled=1
gpgcheck=1
gpgkey=https://packages.microsoft.com/keys/microsoft.asc" /etc/yum.repos.d/vscode.repo'
yum check-update
yum install code
然后就可以进行编程了。同时vscode中支持很多插件，可以根据你的需要进行安装，网上也有很多相关教程可以查看。
