1. Query maximum number of connections:

Db.serverStats () connections

two。 Modify the maximum number of connections:

Shut down the database and restart with the parameter maxConns:mongodb-- port 27017-- dbpath data/-- maxConn

3. Restart to view the maximum number of connections:

Db.serverStats () connections

It's still 819, and it hasn't changed. What's going on? After some research, it is found that this is the limitation of the system, and the maximum number of files that can be opened by the Linux default process is limited and can be solved through ulimit.

4. Set up the system

Switch to superuser ulimit-n 4000 under Linux. You can also add ulimit-n 4000 to the configuration file modification, / etc/rc.local

5. Restart mongodb and check that the maximum number of connections has been changed to 3000

The above is how to optimize the maximum number of connections in Mongodb. Have you learned any knowledge or skills? If you want to learn more skills or enrich your knowledge reserve, you are welcome to follow the industry information channel.
