我用Mac操作的,阿里云ECS,我再初始化磁盘后只做了以下几件事,ssh登陆一直要求我输入密码。
之前用ssh-keygen -t rsa -C "email@example.com"
生成了秘钥,然后在VPS上:
yum update adduser git su git cd ~ mkdir .ssh && cd .ssh touch authorized_keys vim authorized_keys 然后我复制粘贴了我本机的id_rsa.pub中的内容
之后我用ssh git@123.123.123.123
,仍然让我输入密码。
之后我又修改了一下权限问题:
chmod o-w ~/ chmod 700 ~/.ssh chmod 600 ~/.ssh/authorized_keys
然而好像并没有什么卵用,依然让我输入密码。ssh -vvv git@123.123.123.123
中显示是这样的:

真的不知道该怎么办了。。。
请将密钥权限修改为400
chmod 400 /your_key_path/ssh.key
MAC下ssh连接请使用
ssh user@[ip or domain_name] -i /your_key_path/ssh.key
例如:
ssh root@foooo.com -i ./Desktop/ssh.key
如果端口不是默认的22,需要加上-p,例如:
ssh root@foooo.com -p 1234 -i ./Desktop/ssh.key
还不行的话给我留言吧。
那你的 id_rsa 存在本机哪里?
id_rsa(私钥)需要存在本机(你的Mac)的 /Users/dvel/.ssh/id_rsa
你去确定一下是不是真的在那里,权限是不是400。
如果你把私钥放在了别的地方, 要用 ssh -i 私钥路径文件名 git@123.123.123.123
直接在本机执行:
ssh-copy-id user@ip
这样试试吧,不用手动copy了
