1.

preparation and shopping: positioning needs and supplier selection

- clarify the requirements: storage amount, concurrent upload speed, bandwidth peak, whether object storage (s3 compatible) and cdn are required.
- select a supplier: give priority to cloud vendors or overseas vps that have malaysian nodes and do not require icp registration (such as third-party or international cloud vendors that provide my computer rooms), and confirm the export bandwidth and whether it supports on-demand expansion and object storage.
- test latency: use ping/traceroute to test to the target user area (common lines in mainland china will have gfw restrictions). it is recommended to prepare singapore or hong kong as a backup node to optimize distribution.

2.

vps basic environment construction (ssh/firewall/acceleration)

- log in: ssh root@yourip; update the system: apt update && apt upgrade -y or yum update -y.
- firewall: open the necessary ports (22, 80, 443, your upload service port), and use ufw or firewalld to configure the whitelist. example: ufw allow 80/tcp; ufw allow 443/tcp.
- network optimization: enable bbr: add net.core.default_qdisc=fq, net.ipv4.tcp_congestion_control=bbr to /etc/sysctl.conf, and execute sysctl -p. restart verification: sysctl net.ipv4.tcp_congestion_control.

3.

build a resumable upload service (tusd or minio is recommended)

- install tusd (tus protocol implementation, support for resumed downloads): download the binary and configure the storage directory: mkdir /data/uploads; run the example: ./tusd -dir /data/uploads -port 1080 &.
- if object storage is required: deploy minio or use cloud object storage (s3), start minio: minio server /data/uploads --console-address ":9001".
- test upload: use curl or the front-end library (tus-js-client) to upload large files, and verify whether the resumed upload and concurrent fragmentation are normal.

4.

reverse proxy and https (nginx configuration example highlights)

- install nginx and apply for a certificate: apt install nginx certbot; certbot --nginx -d your.domain.
- nginx optimization points: client_max_body_size 10g; client_body_timeout 300s; proxy_buffering off; chunked_transfer_encoding on; increase keepalive_timeout. example location proxy to tusd: proxy_pass http://127.0.0.1:1080; and forward the original header for authentication.
- cors: if the front-end upload needs to be cross-domain, set add_header access-control-allow-origin "*" and so on (it is recommended to limit the domain name for production).

5.

transcoding and slicing (ffmpeg generates hls/multiple bitrates)

- install ffmpeg: apt install ffmpeg.
- transcoding script (example): ffmpeg -i input.mp4 -c:v libx264 -preset fast -b:v 2000k -maxrate 2200k -bufsize 4000k -vf scale=-2:720 -c:a aac -b:a 128k -hls_time 4 -hls_playlist_type vod output_720.m3u8 (generate multiple playlists for different bit rates and generate master.m3u8).
- automation: after the upload is completed, the background queue is triggered (for example, using redis+celery/queue script). after the transcoding is completed, the slice directory is uploaded to the object storage and the cdn is notified to update back to the source.

6.

cdn configuration and caching strategy (accelerated distribution and return to origin)

- select a cdn: you can choose cloudflare, bunnycdn or a cdn that provides nodes in malaysia/southeast asia, and configure the pull zone to point to your object storage or vps domain name.
- cache strategy: set long cache (cache-control: public, max-age=86400) for tiles and static resources, set short cache for m3u8 or force return to the origin so that updates take effect immediately.
- security and anti-hotlinking: enable referer/token authentication and https, and set anti-hotlinking policies to prevent bandwidth abuse.

7.

upload acceleration and client optimization (front-end and tools)

- multi-threaded/sharded upload tool: the front-end uses tus-js-client or resumable.js, and the server supports tusd/minio. the mobile terminal can use the resumable upload sdk or send the upload to the nearest acceleration node first (such as in-app upload to a nearby proxy vps).
- compression/code rate control before uploading: the client can perform simple compression or transcoding to reduce bandwidth usage before uploading (the mobile phone can call the system api or use the sdk).
- monitoring and rollback: monitor the upload failure rate, retry mechanism, logs (nginx/access.log, tusd log) and set rollback strategies (for example, direct connection for small files, multi-part upload for large files).

q: why choose malaysia’s registration-free server to cooperate with douyin distribution?

a: the registration-free server can bypass icp registration restrictions in mainland china and is suitable for overseas or cross-border business; malaysia is geographically close to southeast asia and can provide lower latency for users in this region. at the same time, combining douyin platform external links and cdn can achieve multi-platform distribution and backup.

9.

q: how to ensure a good upload speed for users in mainland china?

a: use a multi-node strategy (malaysia + singapore/hong kong), enable tcp optimization (bbr), use sharded concurrent uploads on the client, combine global cdn and nearby return-to-origin nodes, and use dedicated lines or acceleration services (such as cloudflare argo or commercial acceleration) when necessary to improve stability.

10.

q: what are the common faults and troubleshooting points?

a: common problems include upload timeout (check nginx client_timeout, bbr, bandwidth limit), cors or certificate errors (check https and cors headers), transcoding failure (check ffmpeg logs and dependencies), cdn cache is not updated (clean cache or shorten m3u8 cache). check the logs item by item and troubleshoot according to the steps.
