我正在尝试创建两个相邻的文件夹，/var/www/site并/var/www/overlay@site共存于一个站点中（出于文件权限和部署工具目的）。
我尝试调整基本配置（删除 HTTPS 配置）：
server {
server_name example.com;
root /var/www/site;
location / { try_files $uri $uri/ =404; }
}
进入此，将根向上移动一级：
server {
server_name example.com;
root /var/www;
location / { try_files /site$uri /site$uri/ /overlay@site$uri /overlay@site$uri/ =404; }
}
但这会导致所有页面都返回 404，原因我无法理解。如果我启用调试日志记录，它似乎正在尝试加载例如/var/www/site/site/index.html，我不确定双倍site是从哪里来的。
以下是请求的 debug.log：

答案1
问题出在条目上/site$uri/。它们从规则中收到重定向index，因此对 的请求（例如）/foo在 处找到/site/foo/index.html，然后内部重定向到/site/foo/index.html，然后失败，因为它找不到/site/site/foo/index.html。
我可以通过添加来解决这个问题
location /site/ { try_files $uri =404; }
location /overlay@site/ { try_files $uri =404; }
但这似乎仍然有一些与重定向相关的怪癖。我得到了一个更强大的修复，将我的覆盖更改为如下方式：
server {
server_name example.com;
root /var/www/site;
location / { try_files $uri $uri/ @overlay; }
location @overlay {
root /var/www/overlay@site;
try_files $uri $uri/ =404;
}
}
