澳门新葡4473网站scp报错 -bash: scp: command not found

发布时间:2019-11-02 07:14编辑:项目浏览(77)

    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

    1.创建挂载目录

    # mkdir -p /media/cdrom
    

     

    2.挂载对应系统版本的iso光盘镜像文件

    # mount -o loop -t iso9660 /opt/rhel-server-6.2-x86_64-dvd.iso /media/cdrom
    

     

    3.配置yum文件如下

    # vi /etc/yum.repos.d/rhel-source.repo
    
    [ISO]
    name=iso
    baseurl=file:///media/cdrom/Server/
    enabled=1
    gpgcheck=0
    

    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.
    RSA key fingerprint is e0:fb:fb:67:a0:fc:cd:a5:dc:c8:bc:68:67:b1:93:3f.
    Are you sure you want to continue connecting (yes/no)? yes
    Warning: Permanently added 'oradb24,192.168.1.24' (RSA) to the list of known hosts.
    root@oradb24's password: 
    bash: scp: command not found
    lost connection
    

    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。
