===在CentOS下用scp命令來通過ssh傳輸文件====
1、從服務器上下載文件
scp jiangshan@192.168.1.191:/path/filename /var/local_dir（本地目標目錄）
例如: scp jiangshan@192.168.1.191:/~/hello.txt 把192.168.1.191上的/home/jiangshan/hello.txt 的文件下載到/var/local_dir（本地目標目錄）
2、上傳本地文件到服務器
scp /path/filename jiangshan@192.168.1.191:/path
例如: scp /var/test.txt jiangshan@192.168.1.191:/var/ 把本機/var/目錄下的test.txt文件上傳至192.168.1.191這台服務器上的/var/目錄中
3、從服務器下載整個目錄
scp -r jiangshan@192.168.1.191:/var/remote_dir（遠程目錄） /var/local_dir（本地目錄）
例如:scp -r jiangshan@192.168.0.101:/var/test /var/
4、上傳目錄到服務器
scp -r local_dir jiangshan@192.168.1.191:remote_dir
例如：scp -r test jiangshan@192.168.1.191:/var/ 把當前目錄下的test目錄上傳到服務器的/var/目錄
PS:服務器要開啟讀寫權限
