Git推送在写入对象时冻结，并给出504错误

Question

问题

Git在HTTPS上为81 kB的repo写入对象时挂起(不允许SSH(。来自Nginx的access.log的具体错误消息如下：

POST /Hello-World/.git/git-receive-pack HTTP/1.1" 504 183 "-" "git/2.28.0.windows.1"

背景

我托管Nginx和Git服务器，它们位于安装的Debian映像中。需要注意的是：我的所有网站文件的www都是以只读方式单独安装的。我的Git根文件夹也在www(即www/git(中。

sudo mount -o loop,offset=1 raspbian-stretch-lite.img /mnt/
sudo mount --bind www/ /mnt/usr/share/nginx/www/
sudo mount -o bind,remount,ro /mnt/usr/share/nginx/www

我的Nginx conf如下：

server {
listen 443 ssl;
server_name git.domain.com;
ssl_certificate fullchain.pem;
ssl_certificate_key privkey.pem;
# fast clone static files
location ~ .git/objects/(?:[0-9a-f]+/[0-9a-f]+|pack/pack-[0-9a-f]+.(?:pack|idx))$ {
root /usr/share/nginx/www/git;
limit_except GET HEAD {
allow all;
}
}
location ~ ^.*.git/(HEAD|info/refs|objects/info/.*|git-(upload|receive)-pack) {
root /usr/share/nginx/www/git;
auth_basic "Restricted";
auth_basic_user_file /usr/share/nginx/www/auth;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME /usr/lib/git-core/git-http-backend;
fastcgi_param GIT_HTTP_EXPORT_ALL "";
fastcgi_param GIT_PROJECT_ROOT $realpath_root;
fastcgi_param REMOTE_USER $remote_user;
fastcgi_param PATH_INFO $uri;
fastcgi_param unix:/var/fcgiwrap.socket;
}
location /gitweb.cgi {
root /usr/share/nginx/www/gitweb;
include fastcgi_params:
gzip off;
fastcgi_param SCRIPT_NAME $uri:
fastcgi_param GITWEB_CONFIG $realpath_root/gitweb.conf;
fastcgi_pass unix:/var/fcgiwrap.socket;
}
location / {
root /usr/share/nginx/www/gitweb;
index gitweb.cgi;
}
}

如果我从浏览器访问https://git.domain.com，我会得到一个GitwebGUI。我用git clone https://git.domain.com/Hello-World/.git克隆，一切都很好。但当我尝试使用git push进行推送时，它在编写对象步骤时挂起，最终导致网关超时错误。有趣的是，每次发生这种情况时，https://git.domain.comGit网页和Git后端都会关闭，迫使我终止并重新启动fcgiwrap进程。

我的猜测

我试过git config --global http.postBuffer 524288000，但没有用。由于我正在进行身份验证(通过键入用户名和密码(，应该允许git-receive-pack，对吧？

我认为这与git文件夹没有写入权限有关？也许我的Nginx配置的正则表达式不正确？

编辑：

通常，Git中的错误会进入stderr，stderr通常由web服务器写入日志。你的系统上有这样的日志吗？如果有，它包含什么？

我在客户端的命令提示符中得到的错误如下：

(base) C:UserspairwiseseqHello-World>git push

同样来自Nginx的error.log:

之后，fcgiwrap就完全挂起了。在这一点上，我既不能clone也不能push，并且必须生成一个新的fcgiwrap进程。

Answer 1

你试过这里的答案吗？

git config --add remote.origin.proxy ""

这里还有一个答案，人们抱怨504个错误；"推"；。

一开始推送时我也出现了HTTP 504错误(网关超时(；对我来说，这是由权限问题引起的：fcgiwrap作为用户www数据运行，但git存储库目录归另一个用户所有。
