Can't start Mattermost with systemctl

[emilushi (Eduard Milushi)]

Summary
Mattermost not starting with sudo systemctl start mattermost but works fine with sudo -u mattermost ./bin/mattermost

Running on Ubuntu 20.04.1 LTS, with postgres and nginx as a proxy.
Mattermost version 5.35.2

Steps to reproduce
I have installed Mattermost for a small non-profit project and it was working fine until today that I had to change the maximum number of users per team to 100. Since it did that I entered into the server and was trying to delete a team but mattermost was having issues connecting with postgres, if I fixed the issue with postgres and upgraded Mattermost to the latest version.
After I did the above steps Mattermost stopped working with systemctl, it only works if I call mattermost directly…

Expected behavior
It should normally work as a service and be able to auto start if I reboot the server.

Observed behavior
Here are some logs that I don’t understand why the server start and later it stops again.

FYI on this @streamer45

[agnivade (Agniva De Sarker)]

Hey @emilushi

You mentioned at first that it works fine when you start it with sudo -u mattermost ./bin/mattermost. But from the logs you showed, it looks like the server is starting and then stopping right after. Is this the case with the systemctl start or the manual start?

If this is happening only with systemctl start, would you be able to set the log level to DEBUG and paste the output again?

Also, can you paste your init file here just for completeness?

Thanks!

I have replayed twice but Akismet keeps hiding my replay.

Hi, @emilushi

I compared the standard content of the mattermost.service with yours and the significant difference that I can see here is this:

EnvironmentFile=/etc/mattermost/mmomni.mattermost.env

Can I please confirm if the issue persists if you just use the standard mattermost.service below?

[Unit]
Description=Mattermost
After=network.target
After=postgresql.service
BindsTo=postgresql.service

[Service]
Type=notify
ExecStart=/opt/mattermost/bin/mattermost
TimeoutStartSec=3600
Restart=always
RestartSec=10
WorkingDirectory=/opt/mattermost
User=mattermost
Group=mattermost
LimitNOFILE=49152

[Install]
WantedBy=postgresql.service

Since you mentioned that sudo -u mattermost ./bin/mattermost works, let us look at this avenue first.

I was able to solve the problem.

The problem was here:
Error: failed to load configuration: failed to initialize: failed to create Configurations table: pq: password authentication failed for user "mmuser"

I had to go under: /etc/postgresql/{version}/main/pg_hba.conf and change:
host all all 127.0.0.1/32 md5 and
host all all ::1/128 md5 from md5 to trust.

In the documentation it says change peer and ident to trust and not md5

Thanks to @agnivade for his help.

Now the most interesting part about this is: why was it working perfectly when using sudo -u mattermost ./bin/mattermost

Hi @emilushi which documentation suggests changing the network to trust?

I’m having the exact same symptoms trying to set up a new server, but my existing server works fine with md5. I was under the impression that setting to trust weakens security to an unacceptable level…

These helped me assess the risk, thanks!
