enable sshd in WSL
正常安装 openssh-server:
sudo yum install -y openssh-server
WSL 中的特殊配置:
mv /usr/bin/systemctl /usr/bin/systemctl.old
curl https://raw.githubusercontent.com/gdraheim/docker-systemctl-replacement/master/files/docker/systemctl.py > /usr/bin/systemctl
chmod +x /usr/bin/systemctl
systemctl enable sshd
# 很可能显示失败
systemctl status sshd
# 手动执行 sshd 服务会报错
/sbin/sshd -f /etc/ssh/sshd_config
会报这种错：
Could not load host key: /etc/ssh/ssh_host_rsa_key
解决方法是手动生成：
ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key
最后，重启：
service sshd restart
