安装nginx-full版本

apt install nginx-full

创建一个WebDAV根目录，并授予写入权限。例如，您可以使用以下命令创建并授予权限，/var/www/example.com替换成自己的实际目录路径

mkdir /var/www/example.com
chown www-data:www-data /var/www/example.com

增加nginx的认证,这里用的是用户名密码，user就是你要登陆的用户名，/etc/nginx/.htpasswd换成你自己的文件存放路径

sh -c "echo -n 'user:' >> /etc/nginx/.htpasswd" 
sh -c "openssl passwd -apr1 >> /etc/nginx/.htpasswd"

编辑修改nginx配置文件，在server中增加

# webdav配置
# 认证方式
auth_basic    "Restricted Content";
# 存放认证用户名、密码文件（确认有对应权限）
auth_basic_user_file    /etc/nginx/.htpasswd;
# dav allowed method
dav_methods     PUT DELETE MKCOL COPY MOVE;
# Allow current scope perform specified DAV method
dav_ext_methods PROPFIND OPTIONS;
# In this folder, newly created folder or file is to have specified permission. If none is given, default is user:rw. If all or group permission is specified, user could be skipped
dav_access      user:rw group:rw all:r;
# Temporary folder
client_body_temp_path   /tmp/webdav;
# MAX size of uploaded file, 0 mean unlimited
client_max_body_size    0;
# Allow autocreate folder here if necessary
create_full_put_path    on;

完整示范

server {
  listen 80;
  listen [::]:80;
  server_name example.com;
  root /var/www/example.com;
  index index.html index.htm index.php;
  #return 301 https://$server_name$request_uri;
}
server {
        listen 443 ssl;
