Maintenance mode is a shortcut to serve a temporary error notification to all customers that are visiting your shop informing them to come back at a later time, as it is currently not possible to place an order.
Periodically shop owners and maintainers want to perform upgrades, install extensions or do the necessary maintenance on a shop.
To do this in a secure manner, without customers being able to placing orders that get lost during the operation, maintenance mode is available on your Magento shop.

Maintenance Mode for Magento 2
In contrast to Magento 1, Magento 2 provides an internal mechanism to add IP addresses that should be able to access the site while in maintenance mode, so we don’t need additional configuration in the
index.php to allow developers access to the site while the maintenance flag is set.
Enable the Maintenance Mode in Magento 2 by Setting the maintenance.flag
Instead of placing a
maintenance.flag file in the webroot, Magento 2 looks for a
.maintenance.flag file in the
To do this, log in on your Hypernode, and create the maintenance flag:
If you site is set to maintenance mode ON, an error message will be shown to all visitors of your site:
Allow a Developer Access to a Magento Installation in Maintenance Mode
To allow your developers access to the Magento 2 site while in maintenance mode, add the IP addresses to the var/.maintenance.ip file. This will allow a comma-separated list of IP addresses access to your shop:
echo 188.8.131.52 184.108.40.206 220.127.116.11 >> /data/web/magento2/var/.maintenance.ip
Alternatively you can do this using the bin/magento cli tool:
cd ~/magento2 chmod +x bin/magento bin/magento maintenance:enable --ip=18.104.22.168 --ip=22.214.171.124
When the IP addresses are set in the
.maintenance.ip file, you can use
n98-magerun to achieve the same:
n98-magerun2 sys:maintenance --on n98-magerun2 sys:maintenance --off
For additional information, take a look at the Magento 2 documentation about enabling the maintenance mode.
Serve a Custom Error Message When in Maintenance Mode
To serve the error page in your own style, we should add some layout files in the directory from where error pages are served.
For Magento 2 you can find it in:
A default selection of static files used for error pages is already present in the default directory.
It is not recommended to change files in the default directory as this can cause errors when later security patches need to change the core error files. Therefore, to change the styling or your own error page, first copy the default directory to another directory:
cd /data/web/magento2/errors cp -rv default custom/
Next copy the
cp local.xml.sample local.xml
<skin>custom</skin> in both
design.xml to activate the custom skin we just created:
editor local.xml design.xml
After this change, the static content for error pages is served from
/errors/custom rather than from
You can now start designing and adjust the custom error files to your preferences by changing the files in the
