1.win10设置为开发人员模式，并安装subsystem for linux（命令行输入bash就可以安装）
2.登录并su到root，然后修改/etc/sudoers，在最后一行加（一定要在最后一行）：
youname1 ALL=(ALL) NOPASSWD:ALL
3.修改/etc/apt/sources.list，注释掉原来的源，添加：
deb http://mirrors.163.com/ubuntu/ xenial main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ xenial-security main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ xenial-updates main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ xenial-proposed main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ xenial-backports main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ xenial main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ xenial-security main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ xenial-updates main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ xenial-proposed main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ xenial-backports main restricted universe multiverse
修改后apt-get update
4.安装相关开发软件
sudo apt install -y build-essential
sudo apt install -y gdbserver
sudo apt install -y openssh-server
修改/etc/ssh/sshd_config，把PasswordAuthentication改为yes
sudo ssh-keygen -A
sudo service ssh start 每次启动控制台都需要执行，因为控制台会关掉WSL的所有程序
5.修改ssh端口，默认的22被windows占用了
vi /etc/ssh/sshd_config
如果要使用vs2017调试linux程序，参考：
