Trying to switch MeshCentral from MongoDB to NeDB

JaredBusch

I posted an issues on their github to see if they have a way to handle this.

https://github.com/Ylianst/MeshCentral/issues/246

Obviously, I can reinstall.

This entire thing is a test system, but this database issue could be important, so I asked.

JaredBusch

Exported, cleaned up references to mongo and all better. No Mongo.

Export the database (this uses the running database, so I had to have Mongo fixed)

cd /opt/meshcentral
node node_modules/meshcentral --dbexport"

Go in the config file and remove the "mongodb" line(s) in settings

nano /opt/meshcentral/meshcentral-data/config.json

Restart meshcentral

systemctl restart meshcentral
# or
/opt/meshcentral/mcstop
/opt/meshcentral/mcstart

Import the database

cd /opt/meshcentral
node node_modules/meshcentral --dbimport"

Restart meshcentral

systemctl restart meshcentral
# or
/opt/meshcentral/mcstop
/opt/meshcentral/mcstart

So I resintalled Mongo using this method to get the repo on the system.

4.0.9 installed. but it will not start.

[root@mc ~]# systemctl start mongod
Job for mongod.service failed because the control process exited with error code.
See "systemctl status mongod.service" and "journalctl -xe" for details.

[root@mc ~]# journalctl -u mongod.service

manually executed mongod pointing the DB folder to the meshcentral dat afolder and it all started up

mongod --dbpath /opt/meshcentral/meshcentral-data/

Then restarted the meshcentral service

systemctl start meshcentral

But it is like a brand new instance.

Found my data.. Mongo on Fedora 29 put the database in /var/lib/mongodb
