Before deploying MongoDB in a production environment, consider the Production Notes document which offers performance considerations and configuration recommendations for production MongoDB deployments.
To manually install MongoDB Enterprise Edition from the
.tgz, select the tab
that corresponds with your Mac's processor and complete the following steps:
- ulimit Considerations
- Most Unix-like operating systems limit the system resources that a
process may use. These limits may negatively impact MongoDB operation,
and should be adjusted. See UNIX
ulimitSettings for the recommended settings for your platform.
NoteStarting in MongoDB 4.4, a startup error is generated if the
ulimitvalue for number of open files is under
Follow these steps to run MongoDB Enterprise Edition. These instructions assume that you are using the default settings.
Before you start MongoDB for the first time, you must create the
directory to which the
mongod process will write data.
For example, to create the
sudo mkdir -p ~/data/db
Ensure that the user account running
mongod has read
and write permissions for these two directories. If you are running
mongod as your own user account, and you just created
the two directories above, they should already accessible to your
user. Otherwise, you can use
chown to set ownership,
substituting the appropriate user:
sudo chown <user> ~/data/db sudo chown <user> ~/data/log/mongodb
To run MongoDB, run the
mongod process at the system
prompt, providing the two parameters
from above, and the
fork parameter to run
in the background. Alternatively, you may choose to store the values
fork, and many other parameters in a
mongod process at the system prompt,
providing the three necessary parameters directly on the
mongod --dbpath ~/data/db --logpath ~/data/log/mongodb/mongo.log --fork
mongod --config /usr/local/etc/mongod.conf
macOS Prevents mongod From Opening
macOS may prevent
mongod from running after installation. If
you receive a security error when starting
indicating that the developer could not be identified or verified,
do the following to grant
mongod access to run:
Open System Preferences
Select the Security and Privacy pane.
Under the General tab, click the button to the right of the message about
mongod, labelled either Open Anyway or Allow Anyway depending on your version of macOS.
mongosh session on the same host machine as the
mongod. You can run
without any command-line options to connect to a
mongod that is running on your localhost with the
default port of 27017:
By default, MongoDB launches with
bindIp set to
127.0.0.1, which binds to the localhost network interface. This
means that the
mongod can only accept connections from
clients that are running on the same machine. Remote clients will not be
able to connect to the
mongod, and the
not be able to initialize a replica set unless this value is set
to a valid network interface.
This value can be configured either:
