Rclone搭建Webdav服务+Systemd保活+Nginx反代+CF加速一条龙

废话少说直接上实战：
首先是部署 rclone 二进制和生成密码：

# adduser webdav # su - webdav && mkdir rclone && cd rclone
$ wget https://downloads.rclone.org/v1.61.1/rclone-v1.61.1-linux-amd64.zip
$ unzip rclone-v1.61.1-linux-amd64.zip && mv rclone-v1.61.1-linux-amd64/rclone ./ && rm -rf rclone-v1.61.1-linux-amd64*
$ exit
# cd /home/webdav/rclone && apt-get install apache2-utils && touch htpasswd && htpasswd -B htpasswd webdav_user1
# vim /etc/systemd/system/webdav.service

然后就是配置 systemd 进程保活，将下面的配置复制粘贴进入 vim 编辑器中：

[Unit]
Description=my webdav service
After=network.target
[Service]
User=webdav
# Execute `systemctl daemon-reload` after ExecStart= is changed.
ExecStart=/home/webdav/rclone/rclone serve webdav /home/webdav/Myspaces --addr 127.0.0.1:5000 --htpasswd /home/webdav/rclone/htpasswd
[Install]
WantedBy=multi-user.target

然后将执行下面的命令验证一下服务是否正常和端口是否起来了：

# systemctl daemon-reload && systemctl start webdav && systemctl status webdav
# netstat -lnptu

再然后就是 Nginx 反代了，以下配置由军哥的 lnmp.org 旗下的 lnmp vhost add 命令生成：

server
{
listen 80;
#listen [::]:80;
server_name www.webdav.sharpgan.com webdav.sharpgan.com;
index index.html index.htm index.php default.html default.htm default.php;
#include rewrite/none.conf;
#error_page 404 /404.html;

{expires 12h;}
location ~ /.well-known {allow all;}
location / {return 301 https://$host$request_uri;}
access_log /home/wwwlogs/www.webdav.sharpgan.com.log;
}
server
{

#listen [::]:443 ssl http2;

include rewrite/none.conf;
#error_page 404 /404.html;
# Deny access to PHP files in specific directory

error_page 405 = @app;
location @app {
proxy_pass http://127.0.0.1:5000;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header REMOTE-HOST $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
}
location ~ .*.(gif|jpg|jpeg|png|bmp|swf)$
{expires 30d;}
location ~ .*.(js|css)?$
{expires 12h;}
location ~ /.well-known {allow all;}
location / {
proxy_pass http://127.0.0.1:5000;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header REMOTE-HOST $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
}
access_log /home/wwwlogs/www.webdav.sharpgan.com.log;
error_log /home/wwwlogs/error.webdav.sharpgan.com.log;
}

你最好是执行一下军哥的命令生成一下，因为前者会帮你生成 /usr/local/nginx/conf/ssl/dhparam.pem 这个东西，不太懂，好像跟安全有关。

上面的证书我用的是 cf 的 15 年免费的通配符证书，军哥的命令会提醒你输入证书的路径，照着提示弄就行，实在不太明白的参考一下下面这篇军哥的博客：
https://www.vpser.net/build/lnmp-wordpress-howto-3.html

我来说一下这里面最核心的部分：

location / {
proxy_pass http://127.0.0.1:5000;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header REMOTE-HOST $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
}

这段 Nginx 的配置是整个反代的核心配置。

再然后就是下面这段：

error_page 405 = @app;
location @app {
proxy_pass http://127.0.0.1:5000;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header REMOTE-HOST $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
}
