Magento 2 Maintenance Mode - Enable/Disable/Status

Question

Accepted Answer

Magento 2 provide simple CLI (Command Line Interface) for manage maintenance mode.

Enable maintenance mode:

bin/magento maintenance:enable

Disable maintenance mode:

bin/magento maintenance:disable

Allow access only for specified IPs:

bin/magento maintenance:allow-ips 127.0.0.1,127.0.0.2

Check maintenance mode status:

bin/magento maintenance:status

When you enable maintenance mode, magento creates file [magento_home_directory]/var/.maintenance.flag. For disable maintenance mode, you can just remove this file.
