Mac自带SSH连接虚拟机（以及配置Ubuntu的一些整理）
最近连接学校提供的虚拟机，整理一些内容
连接方式：mac自带的ssh方式（命令行直接输入就可以）
ssh [email protected] -p 22如果把服务器重装后可能会出现ECDSA host key “ip地址” for has changed and you have requested strict checking的错误
解决方法：
#xxx为我们的ip地址，清除你当前机器里关于你的远程服务器的缓存和公钥信息
ssh-keygen -R xxx
#原因：云服务器重装了系统（清除了与我本地SSH连接协议相关信息），本地的SSH协议信息便失效了安装图形化界面
sudo apt-get install xinit
sudo apt-get install gdm #默认源可能会报错，我换成清华的源没问题了
sudo apt-get install kubuntu-desktop更换清华源
cd /etc/apt
# 对于标准的镜像源做个备份
sudo cp sources.list sources.list.bak
# 编辑镜像源文件，将上个步骤获取到的内容替换sources.list里面原有的内容
sudo nano sources.list
#使用gredit替代nano也可以
# 刷新镜像源
sudo apt update替换内容网址：https://mirrors.tuna.tsinghua.edu.cn/help/ubuntu/ 具体如下（版本需要自己选择）
运行python文件的已经常用命令
#输入python可以查看是否有python环境，有没有都会提示安装
python
#输入python3可以直接进入编辑模式，exit()退出
python3
exit()
#另一方方式比较推荐，就是先创建py文件在进行保存
#创建
touch 1.py
#进行编辑
vi 1.py
#运行文件
python3 1.py
编辑文件操作
#进入编辑模型
i
#退出
:q
#保存退出文件
:wq
#强制退出
:q!
一些常用的文件操作
#创建文件
mkdir xxx
touch xxx
#进入文件
cd xxx
#删除文件
rm -f 1.py
#复制文件
cp a b
#移动文件（将a移动到b）
mv a b
#查看当前目录下的文件
ls -h
#如有需要或者具体想知道命令行参数可以自行百度 很容易搜到的修改密码
passwd

You may wish to edit your .bashrc or prepend the Anaconda install location:
$ export PATH=/root/anaconda/bin:$PATH
Thank you for installing Anaconda!安装完后如果运行conda指令发现不存在，说明：没有将安装anaconda的路径添加到系统路径中
这个地方大家可以具体了解，这里不过多介绍了
#/root/anaconda/bin为我安装的路径，这里替换成自己的
echo 'export PATH="/root/anaconda/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc
卸载、删除
#卸载xx为程序
rm -rf xxx
#删除文件
rm xxx
#删除目录
rm -d xx
