To run a mongod process as a daemon (i.e. fork ), and write its output to a log file, use the --fork and --logpath options. You must create the log directory; however, mongod will create the log file if it does not exist.
If the mongod is the primary in a replica set, the shutdown process for this mongod instance has the following steps: 1 Check how up-to-date the secondaries are. 2 If no secondary is within 10 seconds of the primary, mongod will return a message that it will not shut down. You can pass the shutdown command a timeoutSecs argument to wait for a secondary to catch up. 3 If there is a secondary within 10 seconds of the primary, the primary will step down and wait for the secondary to catch up. 4 After 60 seconds or once the secondary has caught up, the primary will shut down.
In a clean shutdown a mongod completes all pending operations, flushes all data to data files, and closes all data files. Other shutdowns are unclean and can compromise the validity of the data files.
You can pass the shutdown command a timeoutSecs argument to wait for a secondary to catch up. If there is a secondary within 10 seconds of the primary, the primary will step down and wait for the secondary to catch up. After 60 seconds or once the secondary has caught up, the primary will shut down.
Only a single process can listen for connections on a network interface at a time. If you run multiple mongod processes on a single machine, or have other processes that must use this port, you must assign each a different port to listen on for client connections.
MongoDB server will be started with the following default settings: 1 Store data in data directory C:datadb 2 Listen to port 27017 for new connections 3 Print out the logs on console
For development purpose, you can reduce the initial data files size of MongoDB server and limit the maximum data files size up to 512MB with --smallfiles option. This option also can reduce the maximum file size of each journal files from 1GB to 128MB.
You can start the MongoDB server with all above options in one command line. Tip: If you have too many options required to start the MongoDB server, it is recommended to use configuration file rather than command line options.
Once in the mongo shell, you can edit with the specified editor by typing edit <variable> or edit <function>, as in the following example: 1 Define a function myFunction:#N#function myFunction () { } 2 Edit the function using your editor:#N#edit myFunction#N#The command should open the vim edit session. When finished with the edits, save and exit vim edit session. 3 In the mongo shell, type myFunction to see the function definition:#N#myFunction#N#The result should be the changes from your saved edit:#N#function myFunction() {#N#print ( "This was edited");#N#}
You can use your own editor in the mongo shell by setting the EDITOR environment variable before starting the mongo shell. Once in the mongo shell, you can edit with the specified editor by typing edit <variable> or edit <function>, as in the following example: The command should open the vim edit session.
The prompt variable can hold strings as well as JavaScript code. If prompt holds a function that returns a string, the mongo shell can display dynamic information in each prompt. You can add the logic for the prompt in the .mongorc.js file to set the prompt each time you start up the mongo shell.
The port numberwill likely be 27017, but for additional security, you can always change it to a different one.
You need to create a user with the userAdminAnyDatabase role, which grants the privilege to create other users on any existing database. The following example will create the useradmin user with password “ thepianohasbeendrinking ”:
Open /etc/mongod.conf with your favorite code editor and search for the following lines:
You can also connect and authenticate in one single step with mongo mongodb://superadmin:thepianohasbeendrinking@<host>:<port> , but this option isn’t advised because it will leave your credentials visible in your terminal history, which any program on your computer can actually read.
The following operation adds a user myTester to the test database who has readWrite role in the test database:
MongoDB is a modern general purpose database that often involves highly sensitive and mission-critical data. Authentication -- the process of verifying the identity of a user -- is therefore one of the most important and central features of MongoDB. The main purposes of authentication are:
MongoDB Atlas and MongoDB Server provide a variety of authentication mechanisms that allow users to secure their deployment, from a simple username/password authentication to a full enterprise-grade authentication mechanism , like LDAP and Kerberos.
