scp檔案到遠端伺服器提示 command not found

一台新的伺服器,準備源碼安裝一些軟體,使用scp複制檔案時提示bash: scp: command not found

排查了一下

[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指令的,密碼輸入也是正确的

加-v參數檢視詳細過程,認證已經通過,判斷應該是遠端伺服器的scp指令沒有安裝.

在遠端伺服器安裝scp指令

[root@talenpc ~]# yum install openssh-clients

一切正常了.
