In production mode the site does not load

[guilhermetb]

Hello,
I'm having problems with Magento 2.2.6
I deploy and when I go to the site it does not load
Here's how I deploy:

php bin/magento deploy:mode:show
Current application mode: production. (Note: Environment variables may override this value.)

rm -rf /var/www/html/magento2/var/view_preprocessed/*
rm -rf /var/www/html/magento2/var/page_cache/*
rm -rf /var/www/html/magento2/pub/static/*

php bin/magento cache:flush
php bin/magento cache:clean

php bin/magento setup:static-content:deploy -f pt_BR en_US

cd /var/www/html/magento2
chown www-data:www-data -R *
find . -type f -exec chmod 644 {} \;
find . -type d -exec chmod 755 {} \;
find ./var -type d -exec chmod 777 {} \;
find ./pub/media -type d -exec chmod 777 {} \;
find ./pub/static -type d -exec chmod 777 {} \;
chmod 777 ./app/etc
chmod 644 ./app/etc/*.xml
chmod 777 ./generated

systemctl restart apache2
systemctl restart varnish
systemctl restart redis-server
systemctl restart mysql

Follows magento settings:
catalog/frontend/flat_catalog_category - 1
catalog/frontend/flat_catalog_product - 1
dev/template/minify_html - 1
dev/js/merge_files - 1
dev/js/enable_js_bundling - 1
dev/js/minify_files - 1
dev/css/merge_css_files - 1
dev/css/minify_files - 1
dev/grid/async_indexing - 1
dev/static/sign - 0

Access the site and error 500 in attachment (error.png)

I modify the /var/www/html/magento2/.htaccess file and add
SetEnv MAGE_MODE developer
The site returns to work correctly without any errors (site.png).
When I comment this line back does not work

I can not find where the error is.
I want to leave the site in production mode but ERROR 500 occurs

I would like your help if possible.

Hello @guilhermetb

sudo chmod -R 0777 var/ pub/ generated/

I gave up this installation
I deleted VPS and created a new one from the beginning
I'm going to use Nginx and PHP-FPM instead of Apache and PHP7.0
Should I use php7.0 from the default repository or add a new repository and use 7.1?

Hello @guilhermetb

You can follow the Magento 2 official document for Magento 2.2.x technology stack requirements:

https://devdocs.magento.com/guides/v2.2/install-gde/system-requirements-tech.html

I struggled with this for hours and then figured out my docker instance was out of space.

Deleted all var/log files and everything started working again.

A symptom was that everytime I would run start my docker swarm it would indeed start 2 or 3 of the services needed for Magento. The expected output if you start your docker swarm multiple times is that it should just tell you each of the services are "up to date" instead of starting any of them.

Hope this helps somebody.
