How to Fix Mysql Connect_Timeout Error Problem

As we have already talked about in the earlier Mysql Connect_Timeout section that the connection time has a default value set. We can modify this value according to ourselves.

There is a file with .cnf format also known as the configuration file. This file has all the configuration of MySQL including the timeout. We will annually edit this file and change the default timeout limit. For your ease, we have demonstrated all the steps to do that which will in the end fix the Mysql Connect_Timeout Issue.

• STEP 1. Get to the server you can use SSH
• STEP 2. Navigate to the below path, the main target is to find my.cnf file

sudo nano /etc/mysql/my.cnf

• STEP 3. Here you have to find timeout configuration and modify it to fit your server

wait_timeout = 28800
interactive_timeout = 28800

• • Wait_timeout is the timeout value set to keep the connection active for the given number of seconds. Although under the PHP  environment is good to keep it at 60 seconds. But Stateful applications use a connection pool that is Java, .NET. Which requires a longer timeout limit and thus the default wait_timeout is set to 8hours so that all the pools are satisfied.
  • Interactive_timeout is basically related to the web application, but no worries it will not affect and it is suggested that keep it low to normal.
• STEP 4. So after you have modified the values, save the changes and close the configuration file
• STEP 5. Finally, to make the changes effective restart Mysql, you can use the below command to do that

sudo /etc/init.d/mysql restart

or

sudo service mysql restart
