Cannot start seahub

#1

I am having an issue with Seafile, I cannot start Seahub when running ./seahub.sh restart command I get the following error:

root@seafile:/opt/seafile/seafile-server-8.0.2# ./seahub.sh restart

Seahub is not running
LC_ALL is not set in ENV, set to en_US.UTF-8
Starting seahub at port 8000 ...
Error:Seahub failed to start.
Please try to run "./seahub.sh start" again

The specs of the box are as follows:

OS: Ubuntu 20.04 (all updates installed)
NGiNX: 1.18 (Ubuntu’s Repo)

Seafile does run:

root@seafile:/opt/seafile/seafile-server-latest# ./seafile.sh start

Seafile controller is already running, pid 16807

But systemctl won’t run it:

root@seafile:/opt/seafile/seafile-server-8.0.2# systemctl start seafile.service
Job for seafile.service failed because the control process exited with error code.
See "systemctl status seafile.service" and "journalctl -xe" for details.

Seahub doesn’t start:

root@seafile:/opt/seafile/seafile-server-latest# ./seahub.sh start

LC_ALL is not set in ENV, set to en_US.UTF-8
Starting seahub at port 8000 ...
Error:Seahub failed to start.
Please try to run "./seahub.sh start" again

What can I do to fix this? What am I doing wrong?

#2

Try ./seahub.sh start-fastcgi. It gives a more verbose output.
(Fastcgi-mode has been discontinued, but the command should still give you information.) There are many different possible reasons why seahub doesn’t start, mostly due to unmet python dependencies.

#5

The issue was the lack of mysqlclient installed via pip3. So the instructions should be updated to install

apt-get install libmysqlclient-dev

and then

pip3 install mysqlclient

#6

How did you determine that was the missing dependency? I’m in a similar boat as you with seahub unable to start, I installed all the pip modules from the instructions plus this mysql client but I’m still stuck, I’d love to be able to figure out the problem but I can’t get any log output or more detailed error message. start-fastcgi just gives me Unknown command: 'runfcgi'.

#8

try pip3 install --timeout=3600 Pillow pylibmc captcha jinja2 sqlalchemy django-pylibmc django-simple-captcha python3-ldap future mysqlclient lxml captcha

If you still get start errors, make sure to run seahub.sh start with your seafile user instead of root to catch any permission problems.

#9

I have never had pip3 on my Debian 10 system. I am running mariadb and getting

django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module.
Did you install mysqlclient?
Error:Seahub failed to start.

even though I have run the following:
apt-get install default-libmysqlclient-dev python-pip3

pip3 --version
pip 18.1 from /usr/lib/python3/dist-packages/pip (python 3.7)

when I run sudo pip3 install future mysqlclient, I get:
error: invalid command ‘bdist_wheel’
Failed building wheel for mysqlclient

Reverting back to 7.1.5 until I have more info on how to potentially resolve this.

#10

Thank you, I was missing the lxml python dependency. Now it’s working. The frustrating part is that this dependency is (apparently) not documented, and that the error messages when a python dependency is missing are completely opaque.

Edit: Seahub not actually working, my eyes fooled me.

#11

Sorry, although I was in fact missing the lxml module, installing it didn’t correct my error. I didn’t see the Seahub failed to start message somehow at first, but when I went to pull up seahub in the browser it didn’t work and when I went back to the terminal I saw that dreaded error message. So I’m back at square one, I can’t start seahub and I have zero error output as to why it won’t work.

#12

I had a similar problem. I needed to install ntfs-3g to get Seahub to start.

#13

Thanks for the suggestion but installing ntfs-3g did not help. It would’ve been very odd if it did since I’m not using ntfs anywhere on the system.

#14

My issue was resolved here: Error:Seahub failed to start - RPI 7.1.5

There was no missing dependency or anything like that, rather the config was pointing to a pids folder that didn’t exist.
