How to Flush the Magento 1.x Caches

There are multiple ways to flush your caches in Magento 1.x

Flush the Magento Cache via the Backend

The easiest way to flush your Magento cache is via the backend. After changing something via the backend you’ll usualy need to flush one or more of the built-in caches. Follow the instructions below to flush individual caches

Login to the Magento backend
Go to System > Cache Management
Click the checkbox of any cache that has been marked Invalidated or use one of the selection options above the list to select a group of caches
Set the Actions dropdown to Refresh and click the Submit button

You can also flush all the caches at once by using either the Flush Magento Cache or Flush Cache Storage at the top of the page. On Hypernode it is safe to use either of these buttons since the var/cache folder that is used by Magento is not shared with any other applications.

Flush the Magento Cache via the Commandline

Another way to flush the Magento caches is via the commandline using Magerun. You can use Magerun to flush specific caches or all caches at once.

With Magerun you can very easily retrieve a list of all caches and their respective status with the following command:

magerun cache:list

This will give you an overview similar to the one below:

+--------------------------------+---------+
| code                           | status  |
+--------------------------------+---------+
| config                         | enabled |
| layout                         | enabled |
| block_html                     | enabled |
| translate                      | enabled |
| collections                    | enabled |
| eav                            | enabled |
| config_api                     | enabled |
| config_api2                    | enabled |
| full_page                      | enabled |
+--------------------------------+---------+

To flush all of the aforementioned caches at once, simply use the command:

magerun cache:flush

To flush one single cache, for example full_page use the command:

magerun cache:flush full_page
