环境:RHEL6.5
使用scp命令报错:
[root@oradb23 media]# scp /etc/hosts oradb24:/etc/
-bash: scp: command not found
查看openssh相关包:
[root@oradb23 ~]# rpm -qa openssh*
openssh-5.3p1-94.el6.x86_64
openssh-server-5.3p1-94.el6.x86_64
发现服务器默认没有安装openssh的客户端。
yum 安装openssh客户端
[root@oradb23 ~]# yum install openssh-clients
[root@oradb23 ~]# rpm -qa openssh*
openssh-clients-5.3p1-94.el6.x86_64
openssh-5.3p1-94.el6.x86_64
openssh-server-5.3p1-94.el6.x86_64
yum配置本地源可参考:http://www.cnblogs.com/jyzhao/p/3938290.html
验证scp命令可用
[root@oradb23 ~]# scp
usage: scp [-1246BCpqrv] [-c cipher] [-F ssh_config] [-i identity_file]
[-l limit] [-o ssh_option] [-P port] [-S program]
[[user@]host1:]file1 ... [[user@]host2:]file2
再次执行:
[root@oradb23 ~]# scp /etc/hosts oradb24:/etc/
The authenticity of host 'oradb24 (192.168.1.24)' can't be established.

Are you sure you want to continue connecting (yes/no)? yes

说明oradb24主机同样没有安装openssh客户端,
在oradb24主机也同样yum 安装,确定scp可用
[root@oradb24 ~]# yum install openssh-clients
[root@oradb24 ~]# scp
usage: scp [-1246BCpqrv] [-c cipher] [-F ssh_config] [-i identity_file]
[-l limit] [-o ssh_option] [-P port] [-S program]
[[user@]host1:]file1 ... [[user@]host2:]file2
再次尝试scp拷贝,这次就可以正常拷贝了。
[root@oradb23 ~]# scp /etc/hosts oradb24:/etc/
root@oradb24's password:
hosts 100% 380 0.4KB/s 00:00
说明scp拷贝,两端都需要保证scp命令可用才可以。
