我正在尝试使用capistrano在AWS EC2实例中部署rails 6应用程序。
1。我已经创建了一个名为"deploy"的用户
2。我加上了本地的rd_rsa。将~/.ssh/authorized_keys
3。net-ssh version 6.1.0*

问题:用户ubuntu@xx.xxx.xxx.xxx (Net::SSH::AuthenticationFailed)通过capistrano认证失败，但可以直接SSH
调试:
- sudo tail -f/var/log/auth.log在服务器上
- 然后尝试cap生产部署:检查我的本地
如果显示此消息错误:
userauth_pubkey: key type ssh-rsa not in PubkeyAcceptedAlgorithms [preauth] appear from auth.log
<解决方案/strong>:
- 编辑/etc/ssh/sshd_config
- 找到PubkeyAuthentication然后uncomment(remove #)
- 添加PubkeyAcceptedKeyTypes = +将 重启sshd
sudo systemctl restart sshd我确定，您还没有配置本地Github代理和密钥。
ssh-add -l
eval "$(ssh-agent -s)"
然后重新运行下面的命令使其工作。
ssh-add id_rsa_key_name
如果上述解决方法无效。然后也使用.pem扩展名执行此操作。
ssh-add ~/.ssh/travel_empire.pem
