我正在尝试构建一个ssh服务,以允许推/拉到phabricator repos。我已经对接了所有服务,目前遇到了一个奇怪的错误,无法执行ssh所需的auth脚本。
php-fpm
和
sshd
特别是,我有以下/etc/ssh/sshd\u配置:
AuthorizedKeysCommand /usr/libexec/phabricator-ssh-hook.sh
AuthorizedKeysCommandUser git
AllowUsers git
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
当我手动运行时
su - git -c "/srv/phabricator/scripts/ssh/ssh-auth.php git"
,我能够成功执行脚本。
固态硬盘
在调试模式下运行时的日志(
/usr/sbin/sshd -d -d -d
),我收到以下错误:

编辑:看起来像
/usr/libexec/phabricator-ssh-hook.sh
实际上执行,但它执行的脚本
/srv/phabricator/bin/ssh-auth
status 127
问题。
我已经了解到,当给定命令未从PATH中找到并且不是内置shell命令(或者无法找到脚本使用的库)时,/bin/sh返回状态127。
这就是说,我能够手动执行脚本,因此状态127似乎不太可能提到这一点。
注意,我可以作为
git
用户也是如此。
