scp是secure?copy的简写,用于在Linux下进行远程拷贝文件的命令,和它类似的命令有cp,不过cp只是在本机进行拷贝不能跨服务器,而且scp传输是加密的。可能会稍微影响一下速度。当你服务器硬盘变为只读?read?only?system时,用scp可以帮你把文件移出来。另外,scp还非常不占资源,不会提高多少系统负荷,在这一点上,rsync就远远不及它了。虽然?rsync比scp会快一点,但当小文件众多的情况下,rsync会导致硬盘I/O非常高,而scp基本不影响系统正常使用。

1.命令格式:

scp?[参数]?[原路径]?[目标路径]
scp?[参数]?[原路径]?[目标路径]

2.命令功能:

scp是?secure?copy的缩写,?scp是linux系统下基于ssh登陆进行安全的远程文件拷贝命令。linux的scp命令可以在linux服务器之间复制文件和目录。

3.命令参数:

-1??强制scp命令使用协议ssh1??

-2??强制scp命令使用协议ssh2??

-4??强制scp命令只使用IPv4寻址??

-6??强制scp命令只使用IPv6寻址??

-B??使用批处理模式(传输过程中不询问传输口令或短语)??

-C??允许压缩。(将-C标志传递给ssh,从而打开压缩功能)??

-p?保留原文件的修改时间,访问时间和访问权限。??

-q??不显示传输进度条。??

-r??递归复制整个目录。??

-v?详细方式显示输出。scp和ssh(1)会显示出整个过程的调试信息。这些信息用于调试连接,验证和配置问题。???

-c?cipher??以cipher将数据传输进行加密,这个选项将直接传递给ssh。???

-F?ssh_config??指定一个替代的ssh配置文件,此参数直接传递给ssh。??

-i?identity_file??从指定文件中读取传输时使用的密钥文件,此参数直接传递给ssh。????

-l?limit??限定用户所能使用的带宽,以Kbit/s为单位。?????

-o?ssh_option??如果习惯于使用ssh_config(5)中的参数传递方式,???

-P?port??注意是大写的P,?port是指定数据传输用到的端口号???

-S?program??指定加密传输时所使用的程序。此程序必须能够理解ssh(1)的选项。

4.使用实例:

scp命令的实际应用概述:

从本地服务器复制到远程服务器:

(1)?复制文件:

命令格式:

scp?local_file?remote_username@remote_ip:remote_folder
scp?local_file?remote_username@remote_ip:remote_folder

或者

scp?local_file?remote_username@remote_ip:remote_file
scp?local_file?remote_username@remote_ip:remote_file

或者

scp?local_file?remote_ip:remote_folder
scp?local_file?remote_ip:remote_folder

或者

scp?local_file?remote_ip:remote_file
scp?local_file?remote_ip:remote_file

第1,2个指定了用户名,命令执行后需要输入用户密码,第1个仅指定了远程的目录,文件名字不变,第2个指定了文件名

第3,4个没有指定用户名,命令执行后需要输入用户名和密码,第3个仅指定了远程的目录,文件名字不变,第4个指定了文件名

(2)?复制目录:

命令格式:

scp?-r?local_folder?remote_username@remote_ip:remote_folder
scp?-r?local_folder?remote_username@remote_ip:remote_folder

或者

scp?-r?local_folder?remote_ip:remote_folder
scp?-r?local_folder?remote_ip:remote_folder

第1个指定了用户名,命令执行后需要输入用户密码;

第2个没有指定用户名,命令执行后需要输入用户名和密码;

 

从远程服务器复制到本地服务器:

从远程复制到本地的scp命令与上面的命令雷同,只要将从本地复制到远程的命令后面2个参数互换顺序就行了。

实例1:从远处复制文件到本地目录

命令:

scp?root@192.168.120.204:/opt/soft/nginx-0.5.38.tar.gz?/opt/soft/
scp?root@192.168.120.204:/opt/soft/nginx-0.5.38.tar.gz?/opt/soft/
