ERROR 1040 (HY000): Too many connections
Occurred:
Error occurred due to connection reached at maximum limit defined in configuration file of MySQL.
Solution:
Increase the current value of the variable “max_connections”.
Check the current value
mysql> show variables like 'max_connections%';
+-----------------+-------+
| Variable_name | Value |
+-----------------+-------+
| max_connections | 1 |
+-----------------+-------+
1 row in set (0.00 sec)
Increase the value of parameter in configuration file or by command:
By Command:
mysql> SET GLOBAL max_connections = 100;
Query OK, 0 rows affected (0.00 sec)
mysql> show variables like 'max_connections%';
+-----------------+-------+
| Variable_name | Value |
+-----------------+-------+
| max_connections | 100 |
+-----------------+-------+
By Configuration file:
Edit the configuration file my.cnf.
vi /etc/my.cnf
Find the variable max_connections under mysqld section.
[mysql]
max_connections = 100
Set into higher value and save the file
Note: If you set max_connection = 1, so MySQL will consider maximum allowed 2 connection. Extra One for Super User.
