问题
I changed the configuration of the application and deployed the new code to production server. Since the application does not parse the configuration files and use precompiled classes I needed to update the cache files.
There is app/console cache:warmup and app/console cache:clear commands. But the cache wasn't updated after invoking these commands, so I had to delete the app/cache folder manually.
Manual deletion is very dangerous operation because it's not atomic so I can remove part of cache during request and this may lead to fatal error.
How should I reload cache?
回答1:
You missed env parameter: app/console cache:clear --env=prod --no-debug
回答2:
i believe you can try
app/console cache:clear --no-warmup

To clear the cache and instantly access the data my fix is
sudo app/console cache:clear --env=prod --no-warmup --no-debug
using this command turns off debug, and doesn't have a warmup time before the data is accessible again
