Hi @yongchao_ma 

You need to provide access to var, pub, generated directory. Run this command on Magento root directory.

sudo chmod -R 777 var/ pub/ generated/

remove sudo if it will not work.

I hope it will work for you.

Thanks

It did not help me, writes the following:

chmod: cannot access 'generated/sudo': No such file or directory
chmod: cannot access 'chmod': No such file or directory
chmod: cannot access '777': No such file or directory

How to fix it?
Nor can I start this CMS ...

Hi @yuriy_evgenich,

Try the following command to setup proper permission to magento directory.

sudo find . -type d -exec chmod 755 {} \; && find . -type f -exec chmod 644 {} \; && chmod u+x bin/magento
After it run the following magento commands in the sequence.


chmod -R 0777 var/ pub/ generated/
rm -rf var/cache/* var/view_preprocessed/* generated/* pub/static/*
php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento setup:static-content:deploy -f
php bin/magento cache:flush
php bin/magento indexer:reindex
chmod -R 0777 var/ pub/ generated/

I hope it will help you!

Vimal Parihar, Thanks, it helped, but not quite, now the whole design is gone, CSS is not working correctly, js page design does not load after installation, or rather, it does not display correctly.

What now?

[Vimal Kumar]

@yuriy_evgenich,
It seems static content not deployed perfectly.

Try once static content deployment again.

Are you working on apache or Ubuntu?

[yuriy_evgenich]

In general, in my situation, the following was: when updating the system, its localization through the compressor, the .htaccess file is deleted from the pub/static folder.

I don’t know for what reason, but it is this file that disappears during updates, additions through the compressor. Add the file manually from backup and the problem was solved.

I recommend this if you have the same problems with the template!

In Centos7 with SELinux running you may also need to do this from your Magento web root

Otherwise SELinux decides your permissions break default policy on the server and will not honour them.

chcon -R -t httpd_sys_rw_content_t var/ pub/ generated/
