复制一个文件到服务器
scp -p 22 /Applications/MAMP/htdocs/h.php root@47.101.131.113://var/www/html
上面往往是端口，root开始是服务器的帐号和根目录，我的是apache所以根目录在/var/www/html目录下面，h.php那一串是我的文件根目录和文件名。
复制一个文件夹（目录）到服务器
scp -r -P 22 /Applications/MAMP/htdocs/api root@47.101.130.113://var/www/html/
以上是复制api这个目录到服务器的根目录。
命令:
scp -r -P 22 /Users/liutao/Desktop/vagrant/newproject/pdfbox 2.zip root@52.38.3://home/wwwroot/报错:

带上密钥:
scp -i ./ioshelpertests.pem /Users/mlh/python/space/Real-Time-Voice-Cloning.zip centos@35..65:/home/centos/成功上传:
sudo scp -i /Users/liutao/Desktop/wangbogamenew.pem /Users/liutao/Desktop/vagrant/newproject/pdfbox2.zip centos@527.43:/tmp/
