baikal - can not (re)start mysql

[Sully]

Hi,

I followed your instructions for installing Dietpi and baikal. (Btw: great Installation and setup routine)
Everything worked fine until I reach the point where I must restart mysql.

All I get is:

Code: Select all

root@DietPi:~# service mysql restart
Job for mysql.service failed. See 'systemctl status mysql.service' and 'journalctl -xn' for details.

with

Code: Select all

root@DietPi:~# systemctl status mysql.service -l

That means I still get the "Baïkal was not able to establish a connexion to the configured MySQL database (as configured in Specific/config.system.php)." error and it doesn´t work.

Any ideas on how to fix that?

Kind Regards

Looks like the Baikal installation is completely breaking mysql. I can't even SIGKILL mysqld process.
EDIT: This was caused by fstrim corrupting fileystem which is disabled in v125

Hi Sully,

Apologies for the delay.

We had some issues with daily FStrim which was possibly corrupting file systems. This was resolved in v125 as a hotfix, although, I think this may be causing your current issues with MySQL.
I tested a BaiKal installation today on v125 and could not replicate the issue.

Would you be able to write a new DietPi image and retry the BaiKal installation? v125 is the current version, your system will update automatically during 1st run.

Hi Fourdee,

thanks for the reply and the help. I will try if it works an tell you the result.

Regards

[Sully]

Installation and stetting up of baikal worked as explained in the manual. So everything seems fixed.
Thanks for the help!:)
Now I only need to figure out the right calendar URLs for Lightning...

Regards

[Sully]

Sorry for bothering you again but could someone tell me please the needed URLs for CalDav and CardDav if I use baikal. (I´m using lightning at the moment)

All info I can find is either for old versions of baikal (0.2.x) or is simply saying: that depends on the way you installed baikal. Since I did not do the installation but DietPi did I can not say ho it was installed.

I would be very thankful for some help!

Hi Sully,

The DietPi install location is the same as the BaiKal online docs for installation: http://sabre.io/baikal/install/

I believe the links your after is (change IP as needed):

Code: Select all

http://192.168.0.112/baikal/html/cal.php
http://192.168.0.112/baikal/html/card.php
http://192.168.0.112/baikal/html/dav.php

Found them using:

We havn't applied any rewrite rules in the DietPi installation, so you may need to add those in manually for now: http://sabre.io/baikal/install/.
Either way, please let us know if you get into any issues.
