一臺新的服務器,準備源碼安裝一些軟件,使用scp複製文件時提示bash: scp: command not found
排查了一下,發現是對端系統沒有安裝openss-client軟件包，導致scp複製文件到對端的時候，報找不到命令的錯誤
[10:28:48 talen@BJB0300 ~ ]$ scp bash-4.2.tar.gz [email protected]: [email protected]'s password: bash: scp: command not found lost connection
本地是有scp命令的,密碼輸入也是正確的
加-v參數查看詳細過程,認證已經通過,判斷應該是遠端服務器的scp命令沒有安裝.

在遠端服務器安裝scp命令
[root@talenpc ~]# yum install openssh-clients
一切正常了.
