我正在尝试构建一个ssh服务以允许推/拉到phabricator仓库。我已经对所有服务进行了docker化，并且当前遇到了一个奇怪的错误，该错误无法执行ssh所需的身份验证脚本。
docker镜像同时运行php-fpm和sshd服务，其思想是将ssh与必需的php脚本结合在一起。
特别是，我有以下/ etc / ssh / sshd_config:
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
(作为附带说明，当我启动sshd时，PrintLastLog引发错误，我认为这不相关，但可能是？)
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。但是，当我在 Debug模式下(
sshd)运行时检查/usr/sbin/sshd -d -d -d日志时，收到以下错误:...other stuff...

我已经读到，当从PATH中找不到给定的命令并且不是内置的shell命令(或者找不到该脚本使用的库)时，/ bin / sh返回状态127。
话虽如此，我能够手动执行脚本，因此状态127不太可能引用此脚本。
上面请注意，我也可以作为
git用户执行。Docker容器版本信息:

最佳答案
我也为此而苦苦挣扎。最终，我发现执行php时PATH中没有phabricator-ssh-hook.sh。就我而言，它安装在/usr/local/bin(默认为FreeBSD)中，因此我添加了:
export PATH="/usr/local/bin:$PATH"
在
phabricator-ssh-hook.sh的最后一行之前。关于docker - sshd AuthorizedKeysCommand抛出状态127，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/45808340/
