我知道这个问题来自可能最受欢迎的问题清单，但是从早上起就一直坚持这个问题，所以值得尝试从社区得到积极回应。我已经查询了各种已经提出的问题及其解决方案，但猜测它不起作用。
我正在关注https://docs.gitlab.com/ee/ci/examples/deployment/composer-npm-deploy.html从gitlab runner向我的服务器编写部署脚本。因此，跑步者（基于ubuntu / docker）需要将文件传输到我的服务器，因为跑步者是动态的（在这种情况下 - 两者都是水滴）
eval $（ssh-agent -s）
nano /root/.ssh/id_rsa_sid（粘贴我服务器的私钥内容（.ssh / id_rsa））
ssh-add /root/.ssh/id_rsa_sid
已添加身份：/root/.ssh/id_rsa_sid（/root/.ssh/id_rsa_sid）
现在，当我执行ssh -v root @ serverip时，我将获得Permission denied（publickey）。 （我也尝试了-i密钥文件路径标记 - 结果相同）
root@ubuntu-512mb-sgp1-01:~/.ssh# ssh -v -i id_rsa_sid root@serverip

正如您所看到的，它将文件作为公钥和私钥进行尝试但失败了。
我去了服务器获取日志：
cat /var/log/auth.log
Jul 5 13:13:16 docker-512mb-sgp1-01 sshd[2371]: Connection closed by 128.yyy.yyy.yy port 43292 [preauth]
请让我知道我做错了什么，或者如果可以 - 请指出我的资源。
答案 0 :(得分：0)
对于像我这样的人（谁来这里寻找答案）
做了一些故障排除，发现这是一个愚蠢的错误。
将服务器的公钥添加到其授权密钥文件中。那样做： - ）
