Magento: PHP Fatal error – Allowed memory size exhausted when bin/magento module:status

This was strange one. When calling simple magento command with PHP CLI I was getting error that allowed memory size was exhausted.

[root@machine ~]# php bin/magento module:status
[root@machine ~]# PHP Fatal error: Allowed memory size of 2097152 bytes exhausted (tried to allocate 32768 bytes) in /path/to/wwww/magentoshot.com/vendor/symfony/console/Application.php on line 951

I checked php.ini and it was set like this:

memory_limit = 2048M

I checked if there are different values for CLI version. It were the same.

Solution was simple. Change your php.ini value for memory_limit and define it in gigabytes instead in megabytes.

memory_limit = 2G

I restarted Apache and it started to work.

Magento – lock administration to specific country

Brute force attacks on Magenta administration are also very common issue, like with WordPress, well maybe a little less :). If you can’t lock your administrations on specific fixed IP addresses, than you can probably lock administration so that is accessible only from your country. Russia and China for example, are countries from which those kind of attacks are very common. So it is good idea to block them.

For this example, I’m doing this on Apache 2.4 with GeoIP module installed. Before you proceed, you should have installed geoip.

To have Magento administration accessible only from Germany (for example), add code bellow to your apache vhost configuration. This geoip was installed on CentOS 7, you should change path to GeoIP.dat accordingly to your installation. You should also change country code to the one that you want access from.

GeoIPEnable On
GeoIPDBFile /usr/share/GeoIP/GeoIP.dat
RewriteEngine on
RewriteCond %{ENV:GEOIP_COUNTRY_CODE} !^DE$
RewriteCond %{REQUEST_URI} ^/(index.php/)?admin/? [NC]
RewriteRule .* - [R=403,L]

Magento – Fatal error: Class Mage not found

Of corse, this can be caused by many different things, but if you’re stuck, without any ideas what could be wrong, than try solution bellow. Compiler stores everything in one file and can cause problems with includes. Just clear compiler and disable it if you don’t need it of corse.

I was getting error like this:

Warning: include(Mage.php): failed to open stream: No such file or directory in /my/web/server/root/public_html/lib/Varien/Autoload.php on line 94 Warning: include(): Failed opening 'Mage.php' for inclusion (include_path='/my/web/server/root/public_html/app/code/local:/my/web/server/root/public_html/app/code/community:/my/web/server/root/public_html/app/code/core:/my/web/server/root/public_html/lib:.:/usr/local/share/pear') in /my/web/server/root/public_html/lib/Varien/Autoload.php on line 94 Fatal error: Class 'Mage' not found in /my/web/server/root/public_html/app/code/core/Mage/Core/functions.php on line 244

Just login into your shell and then execute commands bellow (without comments):

//clear compiler
php compiler.php clear
//disable compiler
php compiler.php disable

It is most likely that this will fix your problem. If not, keep digging 🙂

Hope it helps.
