Befolgt wurde die Anleitung unter: https://manual.seafile.com/deploy/using_mysql.html

Installiert habe ich unter Debian 9:

sudo apt-get install python-setuptools python-ldap python-mysqldb python-urllib3 python-memcache python-requests

Zusätzlich zur Doku wurde installiert:

sudo apt-get install python-pip

damit

python -m pip install Pillow==4.3.0

ausgeführt werden kann

Zusätzlich zur Dokumentation musste Java noch installiert werden:

sudo apt-get install default-jre

Danach konnte das Installations und Konfigurationsskript ausgeführt werden:

~/seafile-pro/seafile-pro-server-6.2.13$ ./setup-seafile-mysql.sh
Checking python on this machine ...
