[root#siad01-pc ~]#

OK, I solved the problem.
I had to remove mysql, mariadb
yum remove mysql
Then I removed /var/lib/mysql and then reinstalled mariadb, mariadb-server, mysql and mysql-server.
then i reinstalled mariadb
Its that simple

x11vnc service failing with exit code

Thanks!
I am trying to setup x11vnc service on raspberry pi 4B platform, but it's failing. Below are the status logs:

Any suggestion on this will be really helpful.
I am expecting to enable x11vnc service on raspberry pi 4B.

RabbitMQ server won't start anymore after assigning username/password

I installed a rabbitmq server and it was active and running fine until I entered:
echo "[{loopback_users, []}]}]." > /etc/rabbitmq/rabbitmq.config
I also assigned a username and password and also assigned the user as administrator. I tried to restart the server after that and it wouldn't restart. Checked the status and it was no longer running. Any idea what I did wrong? Still a rookie, any tips would be great.

I'm sure the answer is right in front of me but I can't seem to pin point it.
please use the new format file config:

Unable to run mongoDB after installation

I'm On fedora 34 and trying to install mongoDB on this machine.
I followed installation instruction from official Docs from here. Everything installed correctly, but now i'm unable to start the service.
I executed sudo systemctl start mongod and it showed

Can you check if the port is been used already by some other process.
