大神们，ssh登录问题求解啊~

jiwang1980

不是权限问题，权限问题应该在/var/log/secure里面有记录吧

我尝试修改权限，仍需密码

换了台虚拟机，没有问题。
人品问题，也不想深究了，谢谢各位回复

试试这个方法，我之前遇到过类似问题，应该还是目录和文件的权限问题：

1. Create a public ssh key, if you haven’t one already.

Look at ~/.ssh. If you see a file named id_dsa.pub then you obviously already have a public key. If not, simply create one. ssh-keygen -t dsa should do the trick.

Please note that there are other types of keys, e.g. RSA instead of DSA. I simply recomend DSA, but keep that in mind if you run into errors.

2. Make sure your .ssh dir is 700:
chmod 700 ~/.ssh


3. Get your public ssh key on the server you want to login automatically.
A simple scp ~/.ssh/id_dsa.pub remoteuser@remoteserver.com: is ok.


4. Append the contents of your public key to the ~/.ssh/authorized_keys and remove it.

Important: This must be done on the server you just copied your public key to. Otherwise you wouldn’t have had to copy it on your server.

Simply issue something like ---
cat id_dsa.pub >> .ssh/authorized_keys while at your home directory.


5. Instead of steps 3 and 4, you can issue something like this:

cat ~/.ssh/id_dsa.pub | ssh -l remoteuser remoteserver.com 'cat >> ~/.ssh/authorized_keys'


6. Remove your public key from the home directory on the server.


7. Done!
You can now login:

ssh -l remoteuser remoteserver.com or ssh remoteuser@remoteserver.com

without getting asked for a password.

补充一点：被远程登录的主机上用户的主目录的权限必须为755
