Linux系统下分发SCP不需要输入密码配置


 首先在每个节点执行一下命令脚本

    mkdir -p ~/.ssh

    chmod 700 ~/.ssh

    /usr/bin/ssh-keygen -t rsa

    然后再需要批量分发的主机上

    touch ~/.ssh/authorized_keys

    ssh 192.168.1.20 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

    说明:192.168.1.20是分发主机的IP地址

    The authenticity of host 'linux1 (192.168.1.100)' can't be established.

    RSA key fingerprint is 2f:cc:a1:4f:2b:67:01:6a:d1:9e:0b:ab:c8:9e:57:a1.

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

    Warning: Permanently added 'linux1,192.168.1.100' (RSA) to the list of known hosts.

    oracle@linux1's password: xxxxx

    在需要分发的主机执行

    chmod 600 ~/.ssh/authorized_keys

    在分发主机验证

    ssh 192.168.1.19 hostname

    RS9

    在分发主机上常见 scp.sh 文件

    从分发主机192.168.1.20向 192.168.1.19、192.168.1.10 分发文件

    scp -r /usr/local/adsit/webapps/preroll/WEB-INF/classes root@192.168.1.19:/home/adsit/

    scp -r /usr/local/adsit/webapps/preroll/WEB-INF/classes root@192.168.1.10:/home/adsit/

    在分发主机执行 scp.sh 实现拷贝功能。
