Auto install Syncwerk Server CE* and PRO**

These installers offer a quick and easy way to set up a production ready Syncwerk Server using MariaDB, Memcached and NGINX as a reverse proxy in under 5 minutes.

* Community Edition ** Professional Edition

What's it for?

Install the Syncwerk Server in a standard and more secure manner then our current out of the box setup scripts offer. Instead of SQLite we're using MariaDB and NGINX instead of Gunicorn.

Supported OS

Debian Wheezy, Jessie & Stretch

Just select the corresponding installer for your OS. All scripts are meant to run with the bare minimum OS setup. We strongly suggest not installing Syncwerk server beside desktop environments or hosting panels like Plesk, ISPConfig, etc. Professional installations which don't follow our setup suggestions, don't qualify for official support. Please keep this in mind.

Minimal installations only!


Never run these scripts on a production server. They are more or less a one trick pony and could seriously damage production systems. Run it only once and delete it afterwards. If something goes wrong, restart with a fresh machine.

As a precaution I have added a few simple checks to abort installation if any of these fails:

  1. Check if you're running this script as root. If not, abort.
  2. Check if the user "syncwerk" exists. If yes, abort.
  3. Check if the directory "/opt/syncwerk" exists. If yes, abort.

Syncwerk Server CE

All installers need to be executed as root. Running them with sudo will not work! Login as root or switch to root with sudo su before installing with these installers. Make sure your OS package repository (e.g. /etc/apt/sources.list) is configured correctly before proceeding.

For Debian Wheezy, Jessie or Stretch (64bit):

apt-get git lsb-release ca-certificates net-tools -y
cd /root
bash syncwerk_v5_debian

Syncwerk Server PRO

You will have to download the Syncwerk Professional Server package prior to the installation and save it to /usr/src/syncwerk/.

FYI: To download Syncwerk Professional you need an account on our download portal. Only pre-existing customers of Syncwerk GmbH (former Seafile GmbH) will receive access to these restricted sources. Contact us at if you have lost your login details.


Where do I find the full installation log? At /root/[installer_name]_installation.log

What's the unprivileged Syncwerk users name syncwerk

How can I change the domain name of the Syncwerk server? Run the syncwerk-server-change-address script on the shell

How can I login as the unprivileged Syncwerk user? Run su - syncwerk -s /bin/bash with root privileges on the shell

How do I update Syncwerk? You will have to handle Syncwerk updates/upgrades manually after the initial installation.

To login as the Syncwerk users run su - syncwerk -s /bin/bash and then proceed with the update procedure as usual.

What do I have to do after the installer has finished?

  1. Delete installer script. You wont need it anymore and might even seriously damage your system if you run it again.
  2. Follow the suggested steps at the end of the installation to finalize your Syncwerk server installation.


If your installation did not finish successfully, check /root/[installer_name]_installation.log for errors.
