# Creating a MongoDB database
|
|
|
|
First create a directory for the database and set permissions:
|
|
|
|
```bash
|
|
$ mkdir /data/db
|
|
$ sudo chown -R `id -un` /data/db
|
|
```
|
|
|
|
Then start the Mongo daemon
|
|
|
|
```bash
|
|
mongod
|
|
```
|
|
|
|
This will run continuously in the terminal and should say somewhere that it is waiting for connections on port `27017`. This command must be executed before you run any backend that interacts with the Mongo database.

|
## MongoDB Compass
|
|
|
|
_Compass_ is a graphical interface for viewing and interacting with the data in your Mongo database. It will automatically load to the default Mongo port: `27017`.

## Arch Linux troubleshooting
|
|
|
|
Most times any problems will be a result of a Mongo process that is already running. Resolve with:
|
|
|
|
```bash
|
|
# Kill running Mongo process...
|
|
# Identify PID
|
|
sudo lsof -iTCP -sTCP:LISTEN -n -P
|
|
sudo kill [pid]
|
|
```
|
|
|
|
Otherwise try the below.
|
|
|
|
```bash
|
|
# Check that the systemd service is runnign for Mongo
|
|
sudo systemctl status mongodb
|
|
|
|
# If not, enable and start service (only need to do this once for machine)
|
|
sudo systemctl enable --now mongodb
|
|
sudo systemctl start --now mongodb
|
|
|
|
# If issues with Mongo daemon...
|
|
# Remove the current socket
|
|
rm /tmp/mongodb-27017.sock
|
|
```
|
|
|
|
For additional command line utilities you will also need to install `mongodb-tools` from the AUR.
