@beaker thank you
Getting the logs, error output
container still exists
docker logs mariadb
if you have removed the containers
stop mariadb from restarting itself without --restart
clear the files/folders in mariadb
rm -rvf /volume1/docker/mariadb/*
or use DSM GUI to delete the files/folders inside mariadb
without --restart always
docker run \
-d \
-v /volume1/docker/mariadb:/var/lib/mysql \
-e MYSQL_ROOT_PASSWORD=root_password \
-e TZ=America/Los_Angeles \
--name mariadb \
mariadb:latest \
--sql-mode=''
Once it exits with error
docker logs mariadb
Could you copy/paste the error logs, probably last 10~20 lines will do…
I think I figured it out (with your help). When I used your run statement, the container didn’t start. But there were a couple log entries.
root@synology:/volume1/docker# docker logs mariadb
2020-05-07 19:44:41-07:00 [Note] [Entrypoint]: Entrypoint script for MySQL Server 1:10.4.12+maria~bionic started.

2020-05-07 19:44:43-07:00 [ERROR] [Entrypoint]: Database is uninitialized and password option is not specified
You need to specify one of MYSQL_ROOT_PASSWORD, MYSQL_ALLOW_EMPTY_PASSWORD and MYSQL_RANDOM_ROOT_PASSWORD
I had a password in the run statement, but I was using a special character. Once I removed that special char, it worked fine w/ Jason’s original run statement. 
Continuing on…

There is no /opt/librenms directory.
Did you create the tables in MariaDB??
Login to your MariaDB container via:
Try this first:
docker exec -it mariadb mysql -u root
If not:
docker exec -it mariadb mysql -u root -p
CREATE DATABASE librenms CHARACTER SET utf8 COLLATE utf8_unicode_ci;
CREATE USER 'librenms'@'%' IDENTIFIED BY 'libre_password';
CREATE USER 'librenms'@'localhost' IDENTIFIED BY 'libre_password';
GRANT ALL PRIVILEGES ON librenms.* TO 'librenms'@'%';
FLUSH PRIVILEGES;
exit
After creating the tables above
docker restart mariadb
Ahhh ok ok. That explains, it happens
This is normal, /opt is in your docker container
Yes, I had completed all those steps.
root@synology:/volume1/docker# docker exec -it mariadb mysql -u root

Ok sweet. MariaDB is settled… let’s tackle LibreNMS next…
Could you post your librenms docker run command too? That way I can refer to both just in case you’ve changed any variables/naming.
At this stage I think you can just post your passwords if they generated, I highly recommend you start from scratch after we managed to deploy this time round, to make sure we start from a clean state.
I used exactly what was in the instructions, changing just the passwd & TZ.

Thanks!
Thanks for the update
Command looks good…
Hmmmm
If the container is still running, could you execute the database setup again and see whether it shows the same errors?
Checking the logs, seems that it can connect into MariaDB but missing the LibreNMS database
Just tested a fresh install… and it worked on my end. Syno 916+
Could you try these commands, I’ve adjusted to match your settings
(ignore the TZ , we’re testing here)
mkdir /volume1/docker/mariadb-test
docker run \
-v /volume1/docker/mariadb-test:/var/lib/mysql \
-e MYSQL_ROOT_PASSWORD="rooting" \
-e TZ=Asia/Singapore \
--name mariadb-test \
-d \
--restart always \
mariadb:latest \
--sql-mode=''
docker exec -it mariadb-test mysql -u root
(if you get error 2002, wait for few seconds and try again)
CREATE DATABASE librenms CHARACTER SET utf8 COLLATE utf8_unicode_ci;
CREATE USER 'librenms'@'%' IDENTIFIED BY 'libre_password';
CREATE USER 'librenms'@'localhost' IDENTIFIED BY 'libre_password';
GRANT ALL PRIVILEGES ON librenms.* TO 'librenms'@'%';
FLUSH PRIVILEGES;
exit
docker restart mariadb-test
mkdir -p /volume1/docker/librenms-test/{logs,rrd}
touch /volume1/docker/librenms-test/custom.config.php

jarischaefer/docker-librenms:latest
(I’m using port 8669 here)
docker exec -it librenms-test setup_database
(this takes a while…)
docker exec librenms-test create_admin
Hopefully everything works, try logging in @ http://10.10.10.50:8669
Let me know if this set of commands works on your end, its basically the same command I ran with change of IP to match yours on the -e BASE_URL
(Fingers crossed 
)
Well, that worked. The only difference I can see is that you added “-it” in docker exec -it librenms-test setup_database command.
Ok, I’ll remove all the containers and images and try again.
Thank you!!!
-Daren
Great!!
Remember to remove the existing data folders for both mariadb and LibreNMS if you are starting fresh 
Still find it weird that it didn’t work during your first attempt…
Maybe it’s the double-quotes for the app_key
This didn’t matter as well I realise when running the database setup. Was hoping it would show real-time database activity with the “-it” option, but it doesn’t, so just wait till the process is finished and it will output at the end
Hi,
I’m trying to set up the SMTP Office 365 relay to send alerts, but it fails.
The configuration seems to be good, but obviously it’s wrongs.
Someone has had the same problem??
Thank you 
Hi @alrodgir and welcome to the forums
What is your setup like?
Check/Allow firewall going out for smtp port 587 on the host that you installed LibreNMS on
1 Like
I’m talking about librenms configuration.
My network admin is reviewing the firewall configuration, I’ll answer you ASAP about this config.
Erm…
which parts are you in control?
Router < > LibreNMS Host (Synology? Server? VM? Laptop? PC?)
If you have another SMTP server to try on, it would be great to filter out whether it is the settings, or network wide blockage
- Another SMTP server
a) Fails
Host/Network Problem
b) Success
Office365 config problem
If you are on Syno and firewall turned on, please make sure SMTP outgoing is allowed. If you have to ask an network admin… they might be blocks/policies in the network that you are unaware of.
When you click on Test Email, what error does LibreNMS returns you?
Oh, sorry for being so concise
My set up is so simply:
Synology NAS with Librenms docker.
The Synology firewall is off.
Moikrotik router.
All output traffic it’s allowed.
Maybe I can try with the Google SMTP server 
When I click the test I obtain this 
But, if I configure a printer to alert directly, with the same config, the printer alert correctly.

Ok now we are getting somewhere… 
It seems the auth returns error, so network is ok as it’s able to contact the smtp server
Try unchecking “Auto TLS” and test again
Yea, this test should help too if above doesn’t work
hi all, an update to recent test deployment of jarischaefer’s LibreNMS image,
