Error too many connections solution for MySQL

The reason for this error is that MySQL forgot to close after the link. When there is a large number of links, there will be errors.

The workaround is to modify the parameter size in the My.cnf file. The specific:

1, query the value of Max_connections. Run command: Show variables like '%max_connections% ';

2. Modify the value of the max_connections. Run command: Set global max_connections=5000;

3. Restart the MySQL service.
