Increasing MySQL Connections Beyond the Default Limit

In MySQL, each socket connection allows a certain number of concurrent connections, typically set to a default of 100. If you encounter situations where this limit proves insufficient, you can adjust it to accommodate your requirements. Here's how to do it:

Dynamic Adjustment (Without MySQL Restart)

To temporarily increase the maximum connections without restarting MySQL, execute the following query:

mysql> SET GLOBAL max_connections = 150;

Note that this change will only be effective until MySQL is restarted.

Permanent Configuration

For a permanent change, edit your MySQL configuration file (my.cnf) and add the following line:

max_connections = 150

Save the file and restart MySQL to apply the changes.
