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。
