I am experiencing the following problem using mongodb.
This is the error, when I check the status:
Screenshot of the error (mongodb.service, status 14)
Screenshot of code in the mongod.config file
Screenshot of the log file
I have tried uninstalling mongodb following every step from the website and install everything again and when I check the status I still get the same error. I have posted the screenshot of the error.
I am using MacBook pro if this matters.
Would really appreciate, if someone can help me fix this.
By changing the owner to monogdb user of
/var/lib/mongodb and /tmp/mongodb-27017.lock has worked for me.
sudo chown -R mongodb:mongodb /var/lib/mongodb
sudo chown mongodb:mongodb /tmp/mongodb-27017.sock
It seems from the log you have a unclean shutdown before. Or, it could also indicates that mongod is already running.
First, make sure mongod is not running already
ps aux | grep mongod
If it's not, remove the file:
rm /tmp/mongodb-27017.sock
Then try systemctl start mongod to start MongoDB again.
After rebooting in the command line,it fixed to problem,don’t know why after stopping mongo and uninstalling and installing it didn’t fix the problem, but after reboot everything is working fine.
This worked for me on Ubuntu 18.04
Go to the TMP directory: cd /tmp
Check if you have the mongodb sock file: ls *.sock
Change the user:group permission: chown mongodb:mongodb <YOUR_SOCK>
Start MongoDB: sudo service mongod start
Check the MongoDB status: sudo service mongod status
If this does not work you can try
sudo reboot

I had a similar issue and even though the permissions were all okay, the service failed to start. I had a look at the mongodb log
sudo tail -40 /var/log/mongodb/mongod.log
It said that the database was shutdown unexpectedly and needed to be repaired. I ran
sudo mongod --repair --config /etc/mongod.conf
This fixed the database, but now changed the permissions. You will need to do the chown steps again.
sudo chown -R mongodb:mongodb /var/lib/mongodb
sudo chown mongodb:mongodb /tmp/mongodb-27017.sock
Start the mongod service. It would be up & running now.
Same happended with CentOS Stream 8
the user for mongodb service is mongo and group is also mongo
sudo chown mongod:mongod /tmp/mongodb-27017.sock
Resolved, after checking the logfile, showing mongodb-27017.sock failed to start.
I have a similar issue. Was a SELinux blocking the normal execution.
So, I did:
# ausearch -c 'mongod' --raw | audit2allow -M my-mongod
# semodule -X 300 -i my-mongod.pp
and then:
$ sudo systemctl start mongod
and check:
sudo systemctl status mongod
chown -R mongodb:mongodb /var/lib/mongodb
chown mongodb:mongodb /tmp/mongodb-27017.sock

I have tried the following steps to install and setup mongodb in my mac from here https://docs.mongodb.com/manual/tutorial/install-mongodb-on-os-x/ but I got the following error when running the final "mongo" command in my terminal:
Error Message - Zsh: Command Not found : mongo
This error msg occurred after trying to install mongodb 4.2 using brew
sudo chown -R $(whoami) $(brew --prefix)/*
then
brew tap mongodb/brew
then
brew install mongodb-community#4.2
and
brew services start mongodb-community#4.2
or
mongod --config /usr/local/etc/mongod.conf
then
ps aux | grep -v grep | grep mongod
and
mongo
running brew services start mongodb-community#4.2 returns:
Successfully started `mongodb-community#4.2` (label: homebrew.mxcl.mongodb-community#4.2)
running ps aux | grep -v grep | grep mongod returns:
9081 0.2 0.5 5528024 41856 ?? S 3:01pm 0:01.48 /usr/local/opt/mongodb-community#4.2/bin/mongod --config /usr/local/etc/mongod.conf
7613 0.0 0.1 4298832 5600 s000 T 2:47pm 0:00.08 vim /usr/local/etc/mongod.conf
running mongod --config /usr/local/etc/mongod.conf returns:
zsh: command not found: mongod
There are also no mongo files in my /usr/local/bin directory after using these commands
I created a data/db folder in my /usr/local/bin directory using the following commands:
sudo mkdir -p /usr/local/bin/data/db
sudo chown -R `id -un` /usr/local/bin/data/db
Running "brew update" returns:
brew update
Updated 1 tap (homebrew/cask).

brew install mongodb-community-shell
Fixed the problem for me.
Solved it by manually installing the mongodb community files and db tools using the website instead. Then copying them into /usr/local/bin. Then ignoring the app permissions whenever calling mongo or related commands in the terminal through System Preferences > Security & Privacy > General.
After googling I found out that mongoimport and the other features have to be installed separately: https://www.mongodb.com/try/download/database-tools
Followed by copying those bin files after extracting them into the same /usr/local/bin directory
Not sure why its' not working through homebrew though
This worked for me, I was having same issue on mongodb-community#4.4
brew reinstall mongodb-community#4.4
On terminal something like this will appear during reinstallation.
copy highlighted path with echo
echo 'export PATH="/opt/homebrew/opt/mongodb-community#4.4/bin:$PATH"' >> ~/.zshrc
Now open another terminal and start mongodb services
brew services restart mongodb/brew/mongodb-community#4.4
write mongo on terminal and here we fly
If you installed the mongodb via Homebrew. Need to add the mongo path in your bash_profile.
Edit the bash_profile vi ~/.bash_profile
Add the below line in EOF export PATH=$PATH:/usr/local/opt/mongodb-community#4.2/bin
After the edit bash_profile. Close all terminals and open them again. mongo command start works.
In addition to #ramesh-babu-t-b 's answer, https://stackoverflow.com/a/68407530/1279516, the issue could also be that your MongoDB installation did add mongod to your path, but the installation happened within the current shell session, and so your shell doesn't have the updates to the PATH variable yet.
In this case, only his last step is still necessary - Open a new console window and retry the mongod command.
I am using iMac to run Apache Solr in command line. done the following:
wget https://apache.mirrors.nublue.co.uk/lucene/solr/8.5.1/solr-8.5.1-src.tgz
tar -xzf solr-8.5.1-src.tgz
cd to /solr
i then typed : bin/solr start and got permissions denied.
I tried sudo bin/solr start -force
and got :password: type password
after typing the password i get sudo: bin/solr command not found
I read that I need to change the solr home directory for better installation as it is denying root access probably?
Appreciate any suggestion to get Solr starting
Thanks
Paul
I think you need to download the binaries instead of the source files, then run:
cd solr/bin
solr create -c yourCore
solr start -p 8983
change the permission to to bin folder
something like:
sudo chmod -R 777 bin
You should download and install the version without scr at the end:
https://apache.mirrors.nublue.co.uk/lucene/solr/8.5.1/solr-8.5.1.tgz
MongoDB automatically updated to 3.6 after doing a system update and was no longer compatible with my old dataset. So I downgraded to 3.4 again, however now the mongo instance won't start at all and exits with error code 100. Any help would be appreciated.
There were a series of issues piggybacking on one another here, but I sorted this out.
Firstly I reverted from 3.6 to 3.4 by uninstalling Mongo:
sudo service mongod stop
sudo apt-get purge mongodb-org*
Then I installed the specific version of Mongo:
apt-get install mongodb-org=3.4.1 mongodb-org-server=3.4.1 mongodb-org-shell=3.4.1 mongodb-org-mongos=3.4.1 mongodb-org-tools=3.4.10
Then I deleted the .lock files:
rm -rf /path/to/mongod.lock
rm -rf /path/to/WiredTiger.lock
Next you have to grant permissions to Mongo again:
sudo systemctl enable mongod
(Make sure the dbpath is correct in /etc/mongod.conf. If you want to make any changes to the mongod.service file, do it now, and remember to run systemctl daemon-reload to set the changes.)
Then finish updating permissions:
sudo chown -R mongodb:mongodb /var/lib/mongodb
sudo chown -R mongodb:mongodb /var/log/mongodb
Now service mongod start or sudo systemctl mongod start should work.

I recently uninstalled postgresql from my computer. I tried to install it again but I faced some problems. I tried to fully uninstall it again like this:
I found al the packages related to postgres:
$ dpkg -l | grep postgres
Them I removed all the packages and related folders :
$ sudo apt-get --purge remove postgresql postgresql-9.3 postgresql-client-9.3 postgresql-client-common postgresql-common postgresql-contrib-9.3
$ sudo rm -rf /var/lib/postgresql/
$ sudo rm -rf /var/log/postgresql/
$ sudo rm -rf /etc/postgresql/
I've tried to install it again, but after the installation I can't access postgres user.
$ sudo apt-get install postgresql postgresql-contrib
$ sudo -i -u postgres
sudo: unable to change directory to /home/postgres: No such file or directory
If I access root I can access postgres but this is what happens:
$ sudo su -
$ su - postgres
No directory, logging in with HOME=/
postgres#rafael-pc:/$ psql
psql (9.3.9)
Type "help" for help.
postgres=# \q
could not save history to file "/home/postgres/.psql_history": No such file or directory
I have no idea what is happening. I've tried to uninstall it many times but I always have some kind of error when I install it back.
Just a guess here, but it sure looks to me like the problem is that there isn't a /home/postgres directory. I'm not sure what may have happened in your uninstall process to remove that, but it looks like that's the cause of the error in both of the steps you list.
Can you try this (or some approximation of these steps, which create that directory and make sure it's owned by the postgres user)?
# sudo mkdir /home/postgres
# sudo chown postgres /home/postgres
I have a standard homebrew install inside of usr/local/
When I try:
Larson-2:~ larson$ brew install postgresql
Error: Cannot write to /usr/local/Cellar
And when I use sudo:
Larson-2:~ larson$ sudo brew install postgresql
Cowardly refusing to `sudo brew install'
What am I doing wrong?
You somehow have limited permissions to /usr/local/Cellar. Brew doesn't like to install with sudo which is why it refuses.
Check the permissions:
ls -ld /usr/local/Cellar
Open them up for writing:
sudo chmod a+w /usr/local/Cellar
Do not use sudo when working with brew (for security reasons).
You've to simple set-up your permissions.
So I would go even further and change the permissions to:
sudo chgrp -R admin /usr/local /Library/Caches/Homebrew
sudo chmod -R g+w /usr/local /Library/Caches/Homebrew
and then apply the specific group (either admin or staff) to user which should be allowed to use brew command. Check groups of your user via: id -Gn).
If there are further issues, run: brew doctor to see what's wrong.
I'd change the group permissions:
$ chgrp -R admin /usr/local/Cellar
$ chmod g+w /usr/local/Cellar
assuming your user account is in group admin.
This also happens if you have multiple users on your machine. If so, it would be best for you to change the user since every other approach would have you messing around with a lot more files and folders than just /usr/local/Cellar
Use su userWhoInstalledBrew.
The problem can be solved by changing the directory's owner to the current user:
sudo chown -R $USER /usr/local

Following the advice chukcha14 provided in his answer at There is no Cellar file in my usr/local dir for brew, I did this:

To have launchd start mongodb/brew/mongodb-community at login:
ln -sfv /usr/local/opt/mongodb-community/*.plist ~/Library/LaunchAgents
Then to load mongodb/brew/mongodb-community now:
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mongodb-community.plist
Or, if you don't want/need launchctl, you can just run:
mongod --config /usr/local/etc/mongod.conf
