将文件从一台服务器复制到另一台服务器的 Shell 脚本

Question

我有 2 台 Solaris 服务器。我想编写一个 shell 脚本，它将文件从一台服务器复制到另一台服务器。

scp /tmp/test/a.war [email protected]:/tmp/

在 PUTTY 中执行上述命令时，将要求我输入目标的密码。使用 PUTTY 时这很好。

如何通过shell脚本运行

scp

命令时输入密码？

提前致谢

Answer 1

您必须设置 SSH 私钥/公钥。

生成后，将公钥行条目放在目标服务器和用户的 ~/.ssh/authorized_keys 文件中。

确保源计算机上的文件（对于将运行 scp/ssh 命令的用户）将具有建议的文件权限 (400)。
