===在CentOS下用scp命令来通过ssh传输文件====
1、从服务器上下载文件
scp jiangshan@192.168.1.191:/path/filename /var/local_dir（本地目标目录）
例如: scp jiangshan@192.168.1.191:/~/hello.txt 把192.168.1.191上的/home/jiangshan/hello.txt 的文件下载到/var/local_dir（本地目标目录）
2、上传本地文件到服务器
scp /path/filename jiangshan@192.168.1.191:/path
例如: scp /var/test.txt jiangshan@192.168.1.191:/var/ 把本机/var/目录下的test.txt文件上传至192.168.1.191这台服务器上的/var/目录中
3、从服务器下载整个目录
scp -r jiangshan@192.168.1.191:/var/remote_dir（远程目录） /var/local_dir（本地目录）
例如:scp -r jiangshan@192.168.0.101:/var/test /var/
4、上传目录到服务器
scp -r local_dir jiangshan@192.168.1.191:remote_dir
例如：scp -r test jiangshan@192.168.1.191:/var/ 把当前目录下的test目录上传到服务器的/var/目录
PS:服务器要开启读写权限
