两台linux服务器相互拷贝文件的两个方法
<p> 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。</p><p>1．命令格式：</p>
<p>scp [参数] [原路径] [目标路径]</p>
<p>2．命令功能：</p>
<p>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。</p>
<p>3．命令参数：</p>
<p>-1 强制scp命令使用协议ssh1 </p>
<p>-2 强制scp命令使用协议ssh2 </p>
<p>-4 强制scp命令只使用IPv4寻址 </p>
<p>-6 强制scp命令只使用IPv6寻址 </p>
<p>-B 使用批处理模式（传输过程中不询问传输口令或短语） </p>
<p>-C 允许压缩。（将-C标志传递给ssh，从而打开压缩功能） </p>
<p>-p 保留原文件的修改时间，访问时间和访问权限。 </p>
<p>-q 不显示传输进度条。 </p>
<p>-r 递归复制整个目录。 </p>
<p>-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。 </p>
<p>-c cipher 以cipher将数据传输进行加密，这个选项将直接传递给ssh。 </p>
<p>-F ssh_config 指定一个替代的ssh配置文件，此参数直接传递给ssh。 </p>
<p>-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。 </p>
<p>-l limit 限定用户所能使用的带宽，以Kbit/s为单位。 </p>
<p>-o ssh_option 如果习惯于使用ssh_config(5)中的参数传递方式， </p>
<p>-P port 注意是大写的P, port是指定数据传输用到的端口号 </p>
<p>-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。</p>
<p>4．使用实例：</p>
<p>scp命令的实际应用概述： </p>
<p>从本地服务器复制到远程服务器： </p>
<p>(1) 复制文件： </p>
<p>命令格式： </p>
<p>scp local_file remote_username@remote_ip:remote_folder </p>
<p>或者 </p>
<p>scp local_file remote_username@remote_ip:remote_file </p>
<p>或者 </p>
<p>scp local_file remote_ip:remote_folder </p>
<p>或者 </p>
<p>scp local_file remote_ip:remote_file </p>
<p>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 </p>
<p>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 </p>
<p>(2) 复制目录： </p>
<p>命令格式： </p>
<p>scp -r local_folder remote_username@remote_ip:remote_folder </p>
<p>或者 </p>
<p>scp -r local_folder remote_ip:remote_folder </p>
<p>第1个指定了用户名，命令执行后需要输入用户密码； </p>
<p>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；</p>
<p> </p>
<p>从远程服务器复制到本地服务器： </p>
<p>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。</p>
<p>实例1：从远处复制文件到本地目录</p>
<p>命令：</p>
<p>scp root@192.168.120.204:/opt/soft/nginx-0.5.38.tar.gz /opt/soft/</p>
<p>输出：</p>
