While I was trying to install mongo db on Mac catalina and when I run sudo mkdir -p /data/db on terminal it was showing read only mode and the folder was not getting created I even tried brew but still the problem was there can anyone please give me a solution
I've installed mongodb-community version 5.0 using brew, following this post's answer for M1 Apple Silicon Macs: How to install Mongodb on Apple M1 chip
Everything works fine, until the 6th step.
After running "mongo" in my terminal, I get the following errors.
I searched over stackoverflow and suspected that perhaps the mongodb service is not running, but the command "brew services list" gives the
following output.
Running "mongod" gives the following error.
Yet, checking "mongo --version" gives a clear indication of installation.
I have also uninstalled mongodb various times, started afresh with the whole procedure.
I'm so frustrated at this point. It would be really helpful if someone could let me know what's wrong in this process/how I could fix it.
PS: This is one of my first posts and I'm sorry if it is not structured well or does not follow a community guideline. I can try to edit the post if any rule is violated.
Thank you.
This solution worked for me
Read-only file system when attempting mkdir /data/db on Mac
rom the official docs https://docs.mongodb.com/manual/tutorial/install-mongodb-on-os-x/
Install homebrew and run the following commands
sudo chown -R $(whoami) $(brew --prefix)/*
then
brew tap mongodb/brew
then
brew install mongodb-community#4.2
and
brew services start mongodb-community
or
mongod --config /usr/local/etc/mongod.conf
then
ps aux | grep -v grep | grep mongod
and
mongo
to verify you can run show dbs in the mongo shell
Please follow this step for reinstalling mongodb, it works for me:
1st: run this command (Prerequisites)
xcode-select --install
\\note: Homebrew requires the Xcode commandline tools
2nd: install Homebrew for M1 chip (Prerequisites)
3rd: run this command to get Homebrew formula that work with mongodb
brew tap mongodb/brew
4th: run this command to get mongodb version 5
brew install mongodb-community#5.0
5th: run this command to run mongodb in the background
brew services start mongodb-community#5.0
// I notice that if I don't run this command I cannot connect to the server and receive the same error message like you
6th: just run mongo and enjoy. I hope it works.
I've tried probably 10 different sites looking how to download MongoDB on M1 Mac. And I would like to put this here for anyone who wants to make a step-by-step guide to get MongoDB working on M1 Macs. Feel free to edit this and provide your steps.
For example if I run the following command (brew install mongodb-community#4.4), the following error occurs:
Error: Cannot install under Rosetta 2 in ARM default prefix (/opt/homebrew)!
To rerun under ARM use:
arch -arm64 brew install ...
To install under x86_64, install Homebrew into /usr/local.
And then I try rerunning in ARM. And it installs successfully. Then I run mongod and get zsh: command not found: mongod. How is this possible?? It's weird because mongo command works just as expected. So mongodb-community is downloaded but I can't access the mongod command.
Does anyone know why? I've tried changing the path but mongod isn't anywhere local...
-- Starting from Rosetta Terminal:
I installed Mongo Db via the official site. I also created the below folder
~/data/db
I added the mongo files in the location as follows :
/usr/local/mongodb
Im using zsh so setting the environment variables as suggested in the bash_profile doesnt work for me.
My .zshrc file looks as follows
export PATH=$HOME/bin:/usr/local/bin:$PATH
export MONGO_PATH=/usr/local/mongodb
export PATH=MONGO_PATH/bin:$PATH
I also ran the source command as follows :
source ~/.zshrc
However even after trying variations of various answers, I still get :
zsh: command not found: mongo
What am I missing here?
I have the same problem when I try to install Mongo with official doc
This instruction help me to run MongoDB on MacOS Mojave 10.14.6
Try mongod --version
If there is no Mongodb installed try enter brew install mongodb
After this check installation again with mongod --version
Then use brew services start mongodb to run MongoDB on startup
Try brew install mongodb-community-shell.
My case:
I did try brew services start mongodb to solve it, but face this issue:
Error: No available formula with the name "mongodb". Did you mean mongosh or monetdb?
Here is a recommendation on how to solve it where brew install mongodb-community-shell mentioed as part install of the latest Mongo shell: https://developpaper.com/fix-mac-brew-installation-mongodb-error-no-available-formula-with-the-name-mongodb/
this one worked for me.in new macbook or air we cant find .zhrc or bash
in new mac its .zprofile. so change the path in .zprofile
export PATH=/opt/homebrew/bin:$PATH
brew install mongodb-community-shell
you can try it it work for me because when downloading mongodb it lacks the shell so when typing mongo in terminal it won't work
I'm on osx6.8 and need to install an earlier version of Mongodb, how do I install an earlier version with HomeBrew?
The below didn't work :(
dream-2:app2 star$ brew install mongodb-2.6.10
Error: No available formula for mongodb-2.6.10
Searching formulae...
Searching taps...
dream-2:app2 star$
Edit:
I'm getting a message to explain how this post is unique compared to another one, well, the answer to the other question is super long and complex and it's specific to postgresql and doesn't really answer my question.
Note: In September 2019 mongodb was removed from homebrew core, so these instructions have been updated to use mongodb-community instead, installed from the external tap.
If your current installation is still the pre-September mongodb package then you will need to use that name when you unlink, stop, relink and start, on the lines marked with #*# below.
Another option is to simply upgrade away from the deprecated package now.
I already have the latest version of mongo installed, thanks to.
brew tap mongodb/brew
brew install mongodb-community
But I want to switch to the old version sometimes. First, install it:
brew search mongo
brew install mongodb-community#3.2
Let's stop the current mongodb, if it is running:
brew services stop mongodb/brew/mongodb-community #*#
# or if you had started it manually
killall mongod
Now I want 3.2 on my PATH instead of the latest:
brew unlink mongodb-community #*#
brew link --force mongodb-community#3.2
(Apparently it needs --force because it is keg-only.)
Now I have 3.2 on my PATH, I can start the test DB:
mongod --version
brew services start mongodb/brew/mongodb-community
# or start your own mongod from the command-line
When I am finished, I can do the reverse to switch back to the latest version:
brew services stop mongodb/brew/mongodb-community
brew unlink mongodb-community#3.2
brew link mongodb-community #*#
brew services start mongodb/brew/mongodb-community #*#
And restart again.
When trying to install old versions of something with homebrew, it's usually useful to start with brew search packagename, in this case, there's a 2.6 version available under homebrew/versions/mongodb26
So, to install that version:
brew install homebrew/versions/mongodb26
Edit
This answer has certainly become very dated. Take a look at the answer below for a valid way to accomplish this in 2021.
curl -O https://fastdl.mongodb.org/osx/mongodb-osx-x86_64-3.2.12.tgz
tar -zxvf mongodb-osx-x86_64-3.2.12.tgz
mkdir -p mongodb
cp -R -n mongodb-osx-x86_64-3.2.12/ mongodb
export PATH=<mongodb-install-directory>/bin:$PATH #path to the dir created in step 3
mkdir -p /data/db
sudo chown -R $(whoami) /data/
mongod
Addition to the excellent answer of joeytwiddle :
if you don't want to link then unlink the old version of the software, you can just run it from the "cellar" (/usr/local/Cellar/), where brew installed it.
Use ls /usr/local/Cellar/ to find the exact path of the executable. For example in my case, to run mongo shell:
/usr/local/Cellar/mongodb#3.6/3.6.7/bin/mongo
Instead of using homebrew you can use docker to install as many versions of mongodb as you want. Each mongodb can then run on separate ports.
Install docker with brew cask install docker and then open Docker.app. After docker is running, go to Terminal and install your mongodb version by selecting an image from https://hub.docker.com/_/mongo/ like so: docker run -d -p 28017:27017 --name mongo4 mongo:latest
Verify that it's running with docker ps and you can connect to mongodb from your app using port 28017. Repeat the steps with a different name and port to install more versions. Enjoy!
I was able to install it using these instructions:
Installing MongoDB on OSX for local development
Over the last week, I’ve been building our MongoDB cluster on EC2 for
production. For development, however, we’ll still need to install
MongoDB locally. I’m running OSX 10.6.8, but these install
instructions should be the same on all modern OSX versions.
Installing on OSX is much more pleasant than on EC2 (actually it’s just as easy on EC2, but since it’s a simpler setup there’s n real configuration or
head scratching).
Download the latest binary:
curl -O http://fastdl.mongodb.org/osx/mongodb-osx-x86_64-2.0.2.tgz
Note!: If
you don’t have wget installed, simply download the file above by
visiting the link in your web browser and move it into your home
directory.
We’re going to install everything under /usr/local/mongodb
to keep things organized.
Create the directories (switch 'youruser' with your home user name):
sudo mkdir /usr/local/mongodb
sudo mkdir /usr/local/mongodb/log
sudo mkdir/usr/local/mongodb/data
sudo chown youruser /usr/local/mongodb/log
sudo chown youruser /usr/local/mongodb/data
sudo chgrp staff /usr/local/mongodb/log
sudo chgrp staff /usr/local/mongodb/data
Un-tar the binaries and move them into the correct folder:
tar -xvzf ~/mongodb-osx-x86_64-2.0.2.tgz
sudo mv ~/mongodb-osx-x86_64-2.0.2/* /usr/local/mongodb/
Create a config file for mongod:
sudo vi /usr/local/mongodb/mongod.conf
Paste:
dbpath=/usr/local/mongodb/data
logpath=/usr/local/mongodb/log/mongod.log
logappend=false
bind_ip=127.0.0.1
Note: dbpath and logpath specify the path to their
respective files, logappend is set to overwrite the log file on each
start of the database server, bind_ip only allows local connections.
Create an alias so that issuing mongod always read the config file:
vi ~/.profile
Paste:
# MongoDB Alias'
alias mongod="/usr/local/mongodb/bin/mongod --config=/usr/local/mongodb/mongod.conf"
All done, you should be able to simply type mongod after you reload the shell to start MongoDB. I
preferred not to start mongod on boot, but there are other who prefer
to and there’s plenty of documentation online to show you how to set
that up with launchd and creating a .plist.

If you want to install an earlier MongoDB version on mac. Go to the link https://docs.mongodb.com/v3.6/tutorial/install-mongodb-on-os-x/ and select the version which you want to install and its very easy to install, just give a try. There will be around 2-3 commands for installation.
For example if you want to install version 3.6
brew tap mongodb/brew
brew install mongodb-community#3.6
If you got some error
If you need to have mongodb-community#3.6 first in your PATH run:
echo 'export PATH="/usr/local/opt/mongodb-community#3.6/bin:$PATH"' >> ~/.bash_profile
Then run
export PATH="/usr/local/opt/mongodb-community#3.6/bin:$PATH"
To confirm if it successfully installed:
mongod -version
