Abhängigkeiten installieren

sudo apt-get install -y python3 python3-setuptools python3-pip libmemcached-dev zlib1g-dev
sudo pip3 install --timeout=3600 Pillow pylibmc captcha jinja2 sqlalchemy django-pylibmc django-simple-captcha python3-ldap lxml

Seafile installieren

cd seafile-server-*
sudo ./setup-seafile-mysql.sh

Server stoppen

sudo seafile-server-latest/seahub.sh stop
sudo seafile-server-latest/seafile.sh stop

Konfiguration

/opt/seafile/conf/seafdav.conf

Um Konflikte mit Tomcat zu vermeiden, in der Konfigurationsdatei 

sudo vi /opt/seafile/conf/seafdav.conf

den Wert für port auf 

port = 8085

ändern.

Benutzer anlegen

Einen System-Benutzer seafile ohne Homeverzeichnis und ohne Loginmöglichkeit, anlegen: 

sudo addgroup --system --no-create-home --disabled-login --gid 1005 seafile
sudo adduser --system --no-create-home --disabled-login --uid 1005 --ingroup seafile seafile

/opt/seafile/seafile-data

sudo mkdir -p /mnt/synology/web1/seafile/backup/init/
sudo mkdir -p /mnt/synology/web1/seafile/
sudo rsync -av /opt/seafile/seafile-data /mnt/synology/web1/seafile/
sudo chmod 700 /mnt/synology/web1/seafile/seafile-data
sudo mv /opt/seafile/seafile-data /mnt/synology/web1/seafile/backup/init/
cd /opt/seafile/
sudo ln -s /mnt/synology/web1/seafile/seafile-data seafile-data

/opt/seafile/seahub-data

sudo mkdir -p /mnt/synology/web1/seafile/seahub-data
sudo rsync -av /opt/seafile/seahub-data /mnt/synology/web1/seafile/
sudo chmod 700 /mnt/synology/web1/seafile/seahub-data
sudo mv /opt/seafile/seahub-data /mnt/synology/web1/seafile/backup/init/
sudo ln -s /mnt/synology/web1/seafile/seahub-data seahub-data

Besitzer ändern

sudo chown -R seafile:seafile /opt/seafile/
sudo chown -R seafile:seafile /mnt/synology/web1/seafile/

Server testen

Damit der Server von aussen erreichbar ist, muss die Datei 

sudo vi conf/gunicorn.conf.py

geöffnet und folgende Zeilen angepasst werden: 

#bind = "127.0.0.1:8000"                                                                                                                                                                                                                     bind = "0.0.0.0:8000"

Danach die Server mit folgenden Kommandos starten: 

sudo -u seafile /opt/seafile/seafile-server-latest/seafile.sh start
sudo -u seafile /opt/seafile/seafile-server-latest/seahub.sh start

Bei fehlerfreiem Start sollte der Server unter http://10.0.0.176:8000/ erreichbar sein.


Wenn alles geklappt hat, können die Server mit folgenden Kommandos wieder gestoppt werden: 

sudo -u seafile /opt/seafile/seafile-server-latest/seahub.sh stop
sudo -u seafile /opt/seafile/seafile-server-latest/seafile.sh stop
