最近介入的中国移动下的一个APP开发项目，之前是在移动机房是centos8,现在因业务需要，迁移到成都的移动机房是移动根据redhat改的big enterprise得服务器！直接下载再上传太慢且麻烦，选用的是ssh到新服务器，然后scp登录到老开发app服务器上拷贝到新服务器，通过scp的命令执行，快速、方便！
1.安卓scp
yum install -y openssh-clients2.命令参数介绍
[root@localhost ~]# scp -h
unknown option -- h
usage: scp [-12346BCpqrv] [-c cipher 使用压缩] [-F ssh_config] [-i identity_file]
[-l limit] [-o ssh_option] [-P port 选择端口] [-S program] 【-r 复制目录】【-v 显示进度，比如查看链接、认证或配置错误】
[[user@]host1:]file1 ... [[user@]host2:]file2
