I am a starter of MongoDB. According to the "Import Example" section of MongoDB 3.2 Manual, the prerequisite for importing data into the database is to have a running mongod instance. With limited background knowledge of MongoDB, I failed to fully understand this line of instruction. Could anyone please give me some explanation on how to run a mongod instance step by step in Mac Terminal? Thanks.
Here are several steps to do start mongodb var mongod
created the ./bin/data/db directory storing mongodb data file.
Start one terminal for mongodb server
Go to mongo/bin, and execute this command
./mongod
Start another terminal for mongodb shell
Go to mongo/bin, and run
./mongo
Now we can connect to mongodb now, more command like show dbs, show collections, use dbname, For more commands in mongodb, refer to db.help()...

mongo is not recognized as an internal or external commandmongodb is not recognized as an internal or external commandI'm encountering these errors after having installed mongodb using a tutorial and after having tried the edit environment variables fix.I've edited the environment variables The mongosh keyword is recognized when I type it in in the command line but mongo and mongodb aren't. Mongod results in something I'm not certain it should be resulting in.is this expected? I noticed that the number of files available in my bin folder which is where mongodb is installed is less than that of others that I've seen.this is my bin folder with less files I also noticed that after installing mongodb, the mongo compass didn't auto install. I did that manually. How can I overcome these errors and start using mongodb?
mongod is the binary that runs the database. It has many flags, documented here. The output you see is expected. You will often run this in the background via --fork and send the output to a logfile.
mongo is the legacy shell that is deprecated as of 6.0 and no longer ships.
mongosh is the new shell that should provide all the same functionality as the legacy shell.
mongodb there is no binary with this name.
If you are trying to connect to MongoDB Atlas or an existing database, you should not need to run mongod yourself.
I am new to mongodb and trying to figure out a lot.
Can we configure shell logging for mongodb? What I mean is the capability to get logs from the Shell to track queries for auditing purposes for version 4?
If so - what commands do we have to run please?
Thank you for your help
There are two versions of MongoDB shell: the newer mongosh and the older/legacy mongo shell.
mongo maintains a history of commands in the .dbshell file. For example, in the Windows 7 environment this can be found at the folder: C:\Users\<user_name>
MongoDB Shell mongosh stores logs for each session and can be retrieved as explained at: Retrieve Shell Logs. For example, in Windows environment this can be found at the folder: C:\Users\<user_name>\AppData\Local\. The log files are of the format <LogID>_log.
I have been running MongoDB on two Windows 10 PCs. However, one has mongo always running it seems where I only need to open command prompt and type mongo. This gives me access to the db on PC #1.
However, on PC #2, I must open command prompt and type mongod. Then I have to open a second command prompt to type in mongo, then I get access to the db on PC #2.
After doing this for about a year, I find I want to just want both PCs to work like PC #1, where I just type in mongo and not mongodb and only have to use one command prompt.
I checked online but there's nothing I found straightforward to accomplish this specifically.
Does anybody know the answer?
If in PC#2, your MongoDB version is < 4.0, then you can't do anything i.e., you have to continue with mongod to start Mongo as you do now.
But if your MongoDB version is >= 4.0 or you want to upgrade from lower version of MongoDB, you can follow the below steps.
Take backup of all databases with mongodump. If it is large volume data, then go through this.
Uninstall your MongoDB using Windows Uninstall Program features.
Reinstall MongoDB using the link.
While installing, ensure you select 'MongoDB Service' feature.
Start the MongoDB now in PC#2 as you do in PC#1.
Restore the old databases with mongorestore.
I'm sorry for this (peraphs) stupid question ... I install meteor and mongodb in my windows computer and i start to write some apps. I don't understand how to use mongo for shoving my db app ... i open one shell in my app dir and launch mongod, in one more shell in the same folder i start mongo.
show dbs
local
use local
switched to db local
show collections
startup_log
system.indexes
Where are my collections? Where is users collection?
When your app is running use this command on a separate command line mongo 127.0.0.1:3001
Meteor keeps the collections in this server. After you run mongo on this server, by writing use meteor you can use db specific to your running app. And then you can display your collections with db.getCollectionNames()
Meteor uses a library called Minimongo that's why it doesn't display if you run show dbs on your mongo shell.
By default it points to port 3001 hence if you are using Robomongo you can just make the set up to watch that port.
To display all your MongoDB collections using the shell, you may check this answer:
How to list all collections in the mongo shell?
You may also use a MongoDB GUI Tool such Robomongo
I have Mongo running but can't use the mongo commands. When I type show collections I get the error show: command not found.
How can I fix this?
I installed with homebrew so my mongo installation is at: /usr/local/Cellar/mongodb/3.0.6 and my databases are at /data /db.
I searched around but couldn't find an answer.
The following didn't help:

Oh, lol. I have to open the Mongo shell (by typing mongo into the terminal) and not just start the database using mongod as I had already done. Well ok then... my problem is solved.
