Clear Cache & Session

  1. FYI.
If you are using a small instance type like t2.micro, we highly recommend you to frequently clear the cache as small instances have insufficient resources. Low performance instances may lead to a webmin crash or a mysql crash or a Cannot Allocate Memory error. So we recommend t2.medium and the higher performance instance types.
  1. Method 1

Login to your magento admin panel and clear cache & session.

We highly recommend using Flush Cache Storage button if you do not configure Redis for other applications except magento.

Originally, this package uses Redis for only magento caching so that you can safely use Flush Cache Storage button to fully clear the cache.

  1. Method 2
Login to phpRedisAdmin. Select local db 2 for cache or local db 1 for session on the top-left of the page, enter * and click button Filter!. Then you may have to press the icon Flush on the top-left of the page to clear the entire database.
  1. Method 3

Login to webmin -> Others -> Command Shell

Type the command:

redis-cli flushall

Click the button Execute command.

  1. Method 4

There is another way to clear cache & session. Open a terminal or SSH client, using your Amazon EC2 SSH public key, SSH into the instance as the ubuntu user using the public IP information for your instance.

Type the following command:

$ redis-cli flushall

Cannot Access to Webmin

  1. After the “Status Checks” of the instance in AWS Console turns to “2/2 checks passed” can you start to access the system, or the initialization process might be interrupted and fail.
  2. Ensure port 10000 is in your security group.
