Overview

Since version 3.0, Resilio requires a license key to run, and it’s not backward compatible with version 2.

Thus, let’s install version 2.8.1 instead.

Install on CentOS 7

3
curl -O -L --progress-bar https://download-cdn.resilio.com/stable/rpm/x86_64/0/resilio-sync-2.8.1.1390-1.x86_64.rpm

sudo yum install resilio-sync-2.8.1.1390-1.x86_64.rpm

Permissions

Refer to this post:

For me, I am ‘root’ on VPS, so: 

1
2
3
sudo usermod -aG root rslsync
sudo usermod -aG rslsync root
sudo chmod g+rw /home/rslsync/_resilio/

To run: 

1
2
sudo systemctl restart resilio-sync
sudo systemctl enable resilio-sync

You should be able to access the web UI at: http://:8888/gui. Note it’s NOT https, and the /gui at the end, very important.

Set to http-only

Set to http-only to avoid “Too many redirects” error on Cloudflare.

1
vi /etc/resilio-sync/config.json

Also, allow remote access by setting listen to 0.0.0.0:8888.
