Tips to fix AWS error establishing a database connection ?
Apply the following tips to resolve this error.
1. Install load balancer
Recently, one of our customers approached us saying that after moving the WordPress blog to to Amazon EC2, he received the below 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
