centos - git clone提示输入密码，公钥无效，在线急等高手解答

Question

环境：阿里云Centos 6.5,客户端msysgit最新版。
主要参考文章：http://freeloda.blog.51cto.com/2033581/1410562
遇到问题参考的链接，/q/1010000000445726
问题依旧。
问题：公钥已配置，且已拷贝到正确目录。git clone时提示输入密码。
万分着急。希望高手帮帮忙！！！

$ git clone git@42.96.xxx.xxx:/opt/data/git/zebenrepos.git

应要求，上msysgit 命令行使用ssh -vvv模式抓取的日志：

第一段：

zxl@ZXL-THINK /c
$ ssh -vvv git@42.96.1xx.2xx

第二段：

debug2: key: /c/Users/zxl/.ssh/id_ecdsa (0x0),
debug2: key: /c/Users/zxl/.ssh/id_ed25519 (0x0),
debug1: Authentications that can continue: publickey,gssapi-keyex,gssapi-with-mi
c,password
debug3: start over, passed a different list publickey,gssapi-keyex,gssapi-with-m
ic,password
debug3: preferred publickey,keyboard-interactive,password
debug3: authmethod_lookup publickey
debug3: remaining preferred: keyboard-interactive,password
debug3: authmethod_is_enabled publickey
debug1: Next authentication method: publickey
debug1: Offering RSA public key: /c/Users/zxl/.ssh/id_rsa
debug3: send_pubkey_test
debug2: we sent a publickey packet, wait for reply
debug1: Authentications that can continue: publickey,gssapi-keyex,gssapi-with-mi
c,password
debug1: Trying private key: /c/Users/zxl/.ssh/id_dsa
debug3: no such identity: /c/Users/zxl/.ssh/id_dsa: No such file or directory
debug1: Trying private key: /c/Users/zxl/.ssh/id_ecdsa
debug3: no such identity: /c/Users/zxl/.ssh/id_ecdsa: No such file or directory
debug1: Trying private key: /c/Users/zxl/.ssh/id_ed25519
debug3: no such identity: /c/Users/zxl/.ssh/id_ed25519: No such file or director
y
debug2: we did not send a packet, disable method

第二段中怀疑没有尝试rsa,故第三段换了dsa

第三段

debug1: Next authentication method: publickey
debug1: Trying private key: /c/Users/zxl/.ssh/id_rsa
debug3: no such identity: /c/Users/zxl/.ssh/id_rsa: No such file or directory
debug1: Offering DSA public key: /c/Users/zxl/.ssh/id_dsa
debug3: send_pubkey_test
debug2: we sent a publickey packet, wait for reply
debug1: Authentications that can continue: publickey,gssapi-keyex,gssapi-with-mi
c,password
debug1: Trying private key: /c/Users/zxl/.ssh/id_ecdsa
debug3: no such identity: /c/Users/zxl/.ssh/id_ecdsa: No such file or directory
debug1: Trying private key: /c/Users/zxl/.ssh/id_ed25519
debug3: no such identity: /c/Users/zxl/.ssh/id_ed25519: No such file or director
y
debug2: we did not send a packet, disable method
debug3: authmethod_lookup password
debug3: remaining preferred: ,password
debug3: authmethod_is_enabled password
debug1: Next authentication method: password
git@42.96.1xx.2xx's password:

看看这日志，实在没搞懂，为什么dsa已经试通了，还去输入密码？

总结一下：（1）、Centos下，此问题出现与s_home_t的目录标签无很大关系，与SELinux也没有很大关系。本人机器.ssh根本就没有标签，也没修改selinux配置。
（2）、参考网上的教程要十分小心。初步分析问题出现在编辑/etc/passwd中禁用git ssh访问：

git:x:500:500::/home/git:/bin/bash ##此行注释掉

git:x:500:500:git version control:/home/git:/usr/bin/git-shell

注意：下面一行的两个数字（应该是UID吧），一定要跟原来的（上面一行注释掉的）一样。如果粗心大意，怎么也想不到问题出在这里！

Answer 2

你可能clone的是https链接的repo，试试clone ssh链接的repo吧，一般会有两个链接的。
我遇到过这个问题，是这样解决的。

Answer 3

把你 git clone 的后续命令给出来

Answer 4

这个根本没法帮你，不知道更多的信息
