How we fix AWS error establishing a database connection

Now let us take a look at how our Support Engineers resolve this error. Also, let’s see some suggestions they provide to tackle this error.

error establishing a database connection

Here, we found that the server load was high.

On further investigation, we could find that some bot requested the website due to which there was high number of connections. As a result, the SQL database could not serve the load.

Thus, we installed a load balancer. That resolved the error.

2. Try rebooting the instance can also resolve the error magically.

3. Sometimes, restarting the MySQL service can also help resolve the error. Here is the command for it.

sudo service mysqld restart

4. If the culprit is not the MySQL service, then webserver like Apache can also cause issues. So we suggest to reboot it as well.

sudo service httpd restart
