export PATH="/usr/local/mongodb/bin:$PATH"We never want to run as super user but create a special daemon _mongod for this.
Get the last used GID:
# Get the last used GID
$ dscacheutil -q group | grep gid | tail -n 1
gid: 399
# Get list of groups
$ dscl . list /Groups PrimaryGroupID
...
# Get list of groups sorted by ID
$ dscl . list /Groups PrimaryGroupID | tr -s ' ' | sort -n -t ' ' -k2,2
...
Therefore, here we will use 400 (make sure it is not taken).
Please note, on OS X, by convention, all daemon users are prefixed with an underscore, such as _daemon.
Before creating a user, we create a group choosing an unused group id:
# Create _mongod group
$ sudo dscl . -create /Groups/_mongod
$ sudo dscl . -create /Groups/_mongod PrimaryGroupID 400
Once done, we create a new user (we use the same id as we did for the group) - no shell is needed for daemon users:
$ sudo dscl . -create /Users/_mongod UniqueID 400
$ sudo dscl . -create /Users/_mongod PrimaryGroupID 400
$ sudo dscl . -create /Users/_mongod UserShell /usr/bin/false
Finally, permissions:
$ sudo chown -R _mongod:_mongod /var/lib/mongodb/
$ sudo chown -R _mongod:_mongod /var/log/mongodb/
$ sudo chown -R _mongod:_mongod /etc/mongodb/
We can now open new terminal and test it works:
# /we run the command as _mongod to see if it works
$ sudo -u _mongod mongod --config /etc/mongodb/conf/mongod.conf
# show program is running
$ ps aux | grep mongod
# (should show program `mongod` running by `_mongod` daemon user)We can create a launchctl start script to start mongod automatically when starting OS X.
