Connection limits in MySQL
Database connections in MySQL are limited to a finite number by default. You can see the existing connection limit through WinSQL. Refer to the image below.
Increasing this limit
There are two approaches to tackle this problem:
- Modify User Limit
- Modify Global Limits
User limits are typically specified when you first create a user. Consider the following SQL statement.
CREATE USER 'francis'@'localhost' IDENTIFIED BY 'frank';
GRANT ALL ON customer.* TO 'francis'@'localhost'
WITH MAX_QUERIES_PER_HOUR 20
To change global connection settings, you can either modify the /etc/my.cnf file with the following line:
max_connections = 250
or, run the following query.
SET GLOBAL max_connections = 100
