密钥loginssh失败，从Mac OSX到CentOS 5远程服务器

我试图设置无密码login从我的mac到我的远程服务器运行CentOS与“用户1”的公共密钥authentication。

我用$ ssh-keygen -t rsa在我的mac上设置一个公钥，然后将mykey.pub文件复制到CentOS user1的.ssh目录中，然后做了一个

 cat mykey.pub >> authorized_keys 

在.ssh目录中。

我还将.ssh目录的权限设置为700，将authorized_keys设置为600。

• SSH和公共/私人密钥
• 为什么SSH坚持让我login？
• SSHlogin不需要重新检查所有的公钥
• 允许系统帐户无需密码login到其他服务器
• 无需代理转发即可跳转主机

当我做一个：

 ssh [email protected] 

它仍然提示我input密码。 这是怎么回事？

这里是我的sshd_config文件在远程机器上的副本：

 Protocol 2 SyslogFacility AUTHPRIV PermitRootLogin no RSAAuthentication yes PubkeyAuthentication yes AuthorizedKeysFile .ssh/authorized_keys PasswordAuthentication yes PermitEmptyPasswords no ChallengeResponseAuthentication no GSSAPIAuthentication yes GSSAPICleanupCredentials yes UsePAM no AcceptEnv LANG LC_CTYPE LC_NUMERIC LC_TIME LC_COLLATE LC_MONETARY LC_MESSAGES AcceptEnv LC_PAPER LC_NAME LC_ADDRESS LC_TELEPHONE LC_MEASUREMENT AcceptEnv LC_IDENTIFICATION LC_ALL X11Forwarding yes Subsystem sftp /usr/libexec/openssh/sftp-server

这是我的ssh -v输出。 我认为系统默认使用id_rsa.pub而不是我命名的mykey.pub和mykey（私钥文件）。

如何告诉系统使用mykey而不是id_rsa？

 -i identity_file Selects a file from which the identity (private key) for RSA or DSA authentication is read. The default is ~/.ssh/identity for protocol version 1, and ~/.ssh/id_rsa and ~/.ssh/id_dsa for pro- tocol version 2. Identity files may also be specified on a per- host basis in the configuration file. It is possible to have multiple -i options (and multiple identities specified in config- uration files). 

 ssh -i mykey [email protected] 

 ssh -vvv <server>
