`wait_timeout` is a system variable in MySQL that sets the amount of time that MySQL waits for activity on a non-interactive connection before closing it.

If you want to check the current value of `wait_timeout`, use the following command:

“`sql
SHOW VARIABLES LIKE ‘wait_timeout’;
“`

To change the `wait_timeout` value, you can use the following command:

“`sql
SET GLOBAL wait_timeout = your_desired_value;
“`
Replace ‘your_desired_value’ with the number of seconds you want to set.

Remember, this configuration should be done carefully as setting a high timeout value may consume server resources unnecessarily, while setting a low value may interrupt long-running processes.
