Not Able to Connect MongoDB server in Manjaro, Error with exit code 100

Question

I installed Mongodb From AUR Pacman, I tried reinstalling the Mongo but it didn't work, I also tried Arch Troubleshooting methods but it didn't work either.

I get following when I try sudo mongod

[omr@auckwell ~]$ sudo mongo
[sudo] password for omr: 
[omr@auckwell ~]$ sudo mongod

Answer 1

Just create a folder inside C:\data\db . My same problem was solved by doing this.

Answer 2

You need to create a folder /data/db

That's what it says in the terminal {"error":"Nonexistent path: data directory /data/db not found. Create the missing directory

You can do this with the command sudo mkdir -p /data/db

Answer 3

Your issue possibly occurs due to the mongod process is down, you must run the commands bellow in order to get the mongod process up:

~$ sudo service mongodb stop

~$ sudo rm /var/lib/mongodb/mongod.lock

~$ sudo mongod --repair --dbpath /var/lib/mongodb

~$ sudo mongod --fork --logpath /var/lib/mongodb/mongodb.log --dbpath /var/lib/mongodb

~$ sudo service mongodb start
