Phabricator SSH

Question

我读过关于堆栈溢出的类似问题的答案，并尝试过这些解决方案，但它们没有奏效。

为了学习目的，我正在我的笔记本电脑(linux 27)上安装噬菌体。我已经设置并运行了它，但是我无法在这台笔记本上观察到任何git回复。我正在解决一些目录权限问题，但我也遇到了一个问题，使用端口2222上的phabricator的ssh，我很想得到一些帮助。以下是我认为有必要进行故障排除的信息。

我遵循这里的说明：hosting/

我已经通过UI设置将我的id_rsa.pub添加到噬菌体中-> SSH公钥(http://phabricator.localhost.com/settings/user/myuseraccount/page/ssh/)

首先，我的噬菌体ssh设置：

[myuseraccount@localhost ~]$ config list |grep ssh 
diffusion.ssh-host
diffusion.ssh-port
diffusion.ssh-user
log.ssh.format
log.ssh.path

[myuseraccount@localhost ~]$ config get diffusion.ssh-host
{   
  "config": [
    {
      "key": "diffusion.ssh-host",
      "source": "local",
      "value": null,
      "status": "unset",
      "errorInfo": null
    },
    {
      "key": "diffusion.ssh-host",
      "source": "database",
      "value": null,
      "status": "unset",
      "errorInfo": null
    }
  ]   
}   
[myuseraccount@localhost ~]$ config get diffusion.ssh-port
{   
  "config": [
    {
      "key": "diffusion.ssh-port",
      "source": "local",
      "value": 2222,
      "status": "set",
      "errorInfo": null
    },
    {
      "key": "diffusion.ssh-port",
      "source": "database",
      "value": null,
      "status": "unset",
      "errorInfo": null
    }
  ]
}
[myuseraccount@localhost ~]$ config get diffusion.ssh-user
{
  "config": [
    {
      "key": "diffusion.ssh-user",
      "source": "local",
      "value": "phssh",
      "status": "set",
      "errorInfo": null
    },
    {
      "key": "diffusion.ssh-user",
      "source": "database",
      "value": null,
      "status": "unset",
      "errorInfo": null
    }
  ]
}
[myuseraccount@localhost ~]$ config get diffusion.ssh.path
{
  "config": [
    {
      "key": "log.ssh.path",
      "source": "local",
      "value": null,
      "status": "unset",
      "errorInfo": null
    },
    {
      "key": "log.ssh.path",
      "source": "database",
      "value": null,
      "status": "unset",
      "errorInfo": null
    }
  ]
}

第二个我的.ssh目录

[myuseraccount@localhost .ssh]$ ls
id_rsa  id_rsa.pub  known_hosts

[myuseraccount@localhost .ssh]$ ls -ltrh
total 12K
-rw-r--r--. 1 myuseraccount myuseraccount  412 May  8 21:52 id_rsa.pub
-rw-------. 1 myuseraccount myuseraccount 1.7K May  8 21:52 id_rsa
-rw-r--r--. 1 myuseraccount myuseraccount  194 May  9 08:18 known_hosts

[myuseraccount@localhost .ssh]$ cat id_rsa.pub > authorized_keys

[myuseraccount@localhost .ssh]$ ls -ltrh
total 16K
-rw-r--r--. 1 myuseraccount myuseraccount  412 May  8 21:52 id_rsa.pub
-rw-------. 1 myuseraccount myuseraccount 1.7K May  8 21:52 id_rsa
-rw-r--r--. 1 myuseraccount myuseraccount  194 May  9 08:18 known_hosts
-rw-rw-r--. 1 myuseraccount myuseraccount  412 May 10 07:56 authorized_keys

[myuseraccount@localhost .ssh]$ chmod 644 authorized_keys

[myuseraccount@localhost .ssh]$ ls -ltrh
total 16K
-rw-r--r--. 1 myuseraccount myuseraccount  412 May  8 21:52 id_rsa.pub
-rw-------. 1 myuseraccount myuseraccount 1.7K May  8 21:52 id_rsa
-rw-r--r--. 1 myuseraccount myuseraccount  194 May  9 08:18 known_hosts
-rw-r--r--. 1 myuseraccount myuseraccount  412 May 10 07:56 authorized_keys

第三，my /etc/ssh/sshd_config.phabricator

[myuseraccount@localhost ~]$ sudo cat /etc/ssh/sshd_config.phabricator
# NOTE: You must have OpenSSHD 6.2 or newer; support for AuthorizedKeysCommand
# was added in this version.

# NOTE: Edit these to the correct values for your setup.

AuthorizedKeysCommand /usr/libexec/phabricator-ssh-hook.sh
AuthorizedKeysCommandUser phssh
AllowUsers phssh myuseraccount

# You may need to tweak these options, but mostly they just turn off everything
# dangerous.

Port 2222
Protocol 2
PermitRootLogin no
AllowAgentForwarding no
AllowTcpForwarding no
PrintMotd no
PrintLastLog no
PasswordAuthentication no
ChallengeResponseAuthentication no
AuthorizedKeysFile none

PidFile /var/run/sshd-phabricator.pid

第四，我/usr/libexec/phabricator-ssh-hook.sh

[myuseraccount@localhost ~]$ sudo cat /usr/libexec/phabricator-ssh-hook.sh
#!/bin/sh

# NOTE: Replace this with the username that you expect users to connect with.
VCSUSER="phssh"

# NOTE: Replace this with the path to your Phabricator directory.
ROOT="/var/www/phabricator/phabricator"


if [ "$1" != "$VCSUSER" ];
then
  exit 1
fi

exec "$ROOT/bin/ssh-auth" $@

第五，我的phabricator用户的.ssh目录(没有)：

[phssh@localhost ~]$ cd .ssh
-bash: cd: .ssh: No such file or directory
[phssh@localhost ~]$

第六个输出来自尝试测试phabircator的ssh用户的ssh访问

提前感谢您的指点、指导或问题。

Answer 1

我找到了答案，我在遵循设置这个问题的指令时，不知何故错过了这个答案，埋没在关于这个问题sshd AuthorizedKeysCommand throws status 127的评论中。

hosting/“脚本本身和脚本所在的父目录都必须由根用户拥有，并且脚本必须具有755权限。如果不这样做，sshd将拒绝执行钩子。”你查过了吗？

剧本不是755！
