Do you hate to see when your Magento 2 store is broken or is in maintenance mode while running Magento 2 deployment commands? Yes? That's great. In the next 5 minutes, we'll help you with this pain. At Magefan we've created a Linux bash script that allows you to run bin/magento setup commands without braking store, long downtime, and losing sales.
Attention! This script is deprecated, we strongly recommend to use Magento 2 Zero Downtime Deployment Extension.
To use Magento 2 zero downtime deployment please follow the steps bellow:
1. Install Magento 2 zero-downtime deployment script
Run these CLI commands in the Magento root directory:
wget -O deploy.zip https://github.com/magefan/magento2-zero-downtime-deploy/archive/master.zip
rm -f deploy.zip
mv magento2-zero-downtime-deploy-master/ deploy
cp deploy/app/static-content-deploy.sh.sample deploy/app/static-content-deploy.sh
cp app/etc/env.php deploy/app/env.php
echo $'\n'deploy/app/env.php >> .gitignore chmod +x deploy/run
2. Configure zero-downtime script
If you use specific static-content deploy commands then edit the file
By default, it has commands to deploy all Magento 2 themes in en_US locale.
If you use Redis or other non-folder storage for session or cache, then edit the file
Make sure that the cache and session are stored in a folder.
3. Use M2 zero-downtime deploy script
To deploy Magento static content (bin/magento setup:static-content:deploy) with NO downtime, use the CLI command:
To generated code and dependency injection configuration (bin/magento setup:di:compile) with NO downtime, use the CLI command:
You can also run the script with multiple parameters, e.g:
deploy/run -d -s
To update Magento 2 modules database data and schema (bin/magento setup:upgrade), use the CLI command:
If you install new extensions then run this command:
deploy/run -m Vendor_Module1 Vendor_Module2
Note that these commands will also run DI and static content generation and this is the only command that put Magento 2 store into maintenance mode for a few seconds while setup:upgrade is running.
Does it really work?
- Yes, it does. We already use it at magefan.com and in a few clients stores to deploy new design and business logic changes. We're happy to share it with you and get feedback.
Certainly, the author could help with more info.
How it works for Multi-Node production websites ? For eg., website running on two VMs under one LB.
interesting script and what if I want to install applications via composer?
Right now it's not a PHP script so it cannot be installed via composer. Maybe in the future, we will create a Magento 2 extension that will do the same, then you will be able to use composer
But when testing, I found that it only works if I have magento in developer mode. If I put magento into production mode, then an error occurs. Does it only work in developer mode? (Magento version 2.3.2)
