Auto clear cache so my Digital Ocean server does not crash

[pablo_williams]

The cache in magento , over time , uses up more and more data until the server is crashed.

How do I automatically have magento clear the cache so my server does not crash AGAIN :

In /admin > cache management > auto cache these 3 :

Additional Cache Management
Flush Catalog Images Cache Pregenerated product images files.
Flush Swatch Images Cache Pregenerated configurable swatches image files.
Flush JavaScript/CSS Cache Themes JavaScript and CSS files combined to one file.

Hi @pablo_williams,

Are you using something different to the base file cache of Magento?

Can you check if the var/cache directory is the cause of the problem? (checking the size of that directory over time)

Hello @pablo_williams,

If in your Magento system, Magento cron jobs are working properly then you define a cronjob which fire on midnight and clear cache.

File1: create config.xml at app/code/community/Vendor/Cleancache/etc/

<?xml version="1.0" encoding="utf-8"?>
<config>
<modules>
    <Vendor_Cleancache>
        <version>1.0.0</version>
    </Vendor_Cleancache>
</modules>
    <global>
        <models>
            <cleancache>
                <class>Vendor_Cleancache_Model</class>
            </cleancache>
        </models>
    </global>
    <crontab>
        <jobs>
            <clean_cache_midnight><!-- identifier -->
                 <schedule>
                     <cron_expr>0 0 * * *</cron_expr> <!-- running cronjob on midnight -->
                 </schedule>
                <run>
                    <model>cleancache/Fire::fireCacheonMidnight</model>
                </run>
            </clean_cache_midnight>
        </jobs>
    </crontab>
</config>

File2: create Fire.php at app/code/community/Vendor/Cleancache/Model/

<?php
class Vendor_Cleancache_Model_Fire
{
    public function fireCacheonMidnight(){

     /**
     * Flush all magento cache
     */
     Mage::app()->cleanCache();
    }
}

File3: module config file Vendor_Cleancache.xml at app/etc/modules/

<?xml version="1.0" encoding="utf-8"?>
<config>
    <modules>
        <Vendor_Cleancache>
            <active>true</active>
            <codePool>community</codePool>
        </Vendor_Cleancache>
    </modules>
</config>
