我通过在每个工作站上生成公钥并将它们复制到另一个工作站来在两个工作站之间配置SSH连接。现在我可以在没有密码的情况下从一个站连接到另一个站，但如果我想编写一个bash脚本来连接ssh，它仍然要求输入密码。我应该怎么做才能运行脚本后我不会被要求输入密码？
编辑：添加脚本。我在station1上，我想连接到station2（主机）。
#!/bin/bash
ssh host
Edit2：ssh -v输出

Edit3：station2名称是主机
答案 0 :(得分：4)
您的脚本在root帐户下运行：
debug1: Reading configuration data /root/.ssh/config
因此，它不会使用user帐户的密钥。
我们不知道你是如何运行脚本的。
但也许你可以使用su或sudo：
su - user -c /home/user/script.sh
答案 1 :(得分：2)
你可以使用这个
w或在你的〜/ .ssh / config中，添加这样的文字
ssh -i /path/to/key/file user@host
现在，您可以像这样登录
Host foobar
HostName 1.2.3.4
Port 22
User root
IdentityFile ~/.ssh/id_rsa
