我有这样的密钥configuration，我可以这样login到SVN_HOST：
ssh <USER_NAME>@<SVN_HOST> 将无需密码提示将我login到SVN_HOST。 到现在为止还挺好; 然而：
svn update svn+ssh://<USER_NAME>@<SVN_HOST>/<PATH_TO_REPO> <DEST_PATH>
仍然提示：
<USER_NAME>@<SVN_HOST>'s password:
当我input密码时，它按我所期望的那样工作。 不过，我不明白为什么它坚持在svn + ssh情况下提示input密码。
提前致谢。
编辑：根据要求，详细SSH通过放：
SVN_SSH="ssh -v " svn update svn+ssh://<USER_NAME>@<SVN_HOST>/<PATH_TO_REPO> <DEST_PATH>
结果是：
OpenSSH_5.9p1 Debian-5ubuntu1, OpenSSL 1.0.1 14 Mar 2012 debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 19: Applying options for * debug1: Connecting to <SVN_HOST> [<SVN_HOST>] port 22. debug1: Connection established. debug1: permanently_set_uid: 0/0 debug1: identity file /root/.ssh/id_rsa type -1 debug1: identity file /root/.ssh/id_rsa-cert type -1 debug1: identity file /root/.ssh/id_dsa type -1 debug1: identity file /root/.ssh/id_dsa-cert type -1 debug1: identity file /root/.ssh/id_ecdsa type -1 debug1: identity file /root/.ssh/id_ecdsa-cert type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_5.1p1 Debian-5ubuntu1 debug1: match: OpenSSH_5.1p1 Debian-5ubuntu1 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.9p1 Debian-5ubuntu1 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-ctr hmac-md5 none debug1: kex: client->server aes128-ctr hmac-md5 none debug1: SSH2_MSG_KEX_DH_GEX_REQUEST(1024<1024<8192) sent debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP debug1: SSH2_MSG_KEX_DH_GEX_INIT sent debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY debug1: Server host key: RSA cd:32:17:49:fa:19:aa:64:57:91:76:0d:76:19:82:2f debug1: Host '<SVN_HOST>' is known and matches the RSA host key. debug1: Found key in /root/.ssh/known_hosts:1 debug1: ssh_rsa_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: Roaming not allowed by server debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey,password debug1: Next authentication method: publickey debug1: Trying private key: /root/.ssh/id_rsa debug1: Trying private key: /root/.ssh/id_dsa debug1: Trying private key: /root/.ssh/id_ecdsa debug1: Next authentication method: password

input密码后：

关键一代是这样做的：
ssh-keygen
使用默认值，然后：
ssh-copy-id -i ~/.ssh/id_rsa.pub <USER_NAME>@<SVN_HOST>
您以普通用户身份生成密钥，因此将其存储在/home/bob/.ssh/ 。 你在sudo下运行svn作为root，所以SSH客户/root/.ssh/在/root/.ssh/寻找密钥。 您需要以普通用户的身份运行svn ，将密钥复制到/root/.ssh/ ，或者configurationssh以在别处查找密钥：
sudo SVN_SSH="ssh -i /home/bob/.ssh/id_rsa " svn update ...
