一台新的服务器,准备源码安装一些软件,使用scp复制文件时提示bash: scp: command not found

排查了一下
[10:28:48 talen@BJB0300 ~ ]$ scp bash-4.2.tar.gz root@10.10.56.11:
root@10.10.56.11's password:
bash: scp: command not found
lost connection
本地是有scp命令的,密码输入也是正确的
加-v参数查看详细过程,认证已经通过,判断应该是远端服务器的scp命令没有安装.

[10:31:41 talen@BJB0300 ~ ]$

在远端服务器安装scp命令
[root@talenpc ~]# yum install openssh-clients

一切正常了.
