在 VPS 宿主机包一个 nginx，解决 tls 问题，nginx 配置如下，证书和域名相关配置自行修改

我这样运行了一个多月，一直正常无误，但是有一个问题比较困扰：创建了文件夹无法重命名，创建了文件也同样无法重命名。今天看了一下后台日志（日志文件：seafile 容器中的 /opt/seafile/logs/seafdav.log），发现是

MOVE /webdav/test.md" dest="https://xxx/seafdav/webdav/testabc.md", length=0, depth=0, overwrite=F, elap=0.014sec -> 502 Bad Gateway

这并非什么写入权限不对等问题，这样看应该是 nginx 的配置不当导致的，nginx 反向代理下的 http 请求配置错误导致的 502 bad gateway。

最终发现这个回答下的 @eruditewriter 提出的方案解决了我的问题，非常感谢！详细请阅读此帖: https://forum.seafile.com/t/seafdav-move-command-causing-502/11582/25

最终我的解决方案，找到容器中 nginx 配置文件 /shared/nginx/conf/seafile.nginx.conf 在 server 块最外围增加如下代码

map $http_destination $nossl_destination {
    "~^https:(.+)$" $1;
    "~^http:(.+)$" $1;
}

再在 location /seafdav 代码块中增加一行配置

proxy_set_header Destination "http:$nossl_destination";

在容器中执行 nginx -t、nginx -s reload 之后再次测试重命名文件，it works!!!

看下日志

MOVE /webdav/test.md" dest="http://xxx/seafdav/webdav/test-tt.md", length=0, depth=0, overwrite=F, elap=0.035sec -> 204 No Content

204 No Content 。问题已解决。
