cache dir is not writable - centos 7 nginx magento...

matt_ryding · ‎10-02-2020

I have tried for many hours to resolve this issue but no success, please see the attached image.

To test I have given /var/ folder and all inside 777 permissions, but I still receive this not writable error.

Could anyone assist?

@matt_ryding I can not see your image however I will try to resolve your issue. It related to permission, so you can reset it by

find . -type f -exec chmod 644 {} \;
find . -type d -exec chmod 755 {} \;
find var pub/static pub/media app/etc generated/ -type f -exec chmod g+w {} \;
find var pub/static pub/media app/etc generated/ -type d -exec chmod g+ws {} \;
chown -R <Magento user>:<web server group> .
chmod u+x bin/magento

As '777' permission is not recommended.

Please let me know if issue not solved

Hi Shrinet,

Thank you for your response below, I have followed these steps but the error persists, please see below.

After changing the permissions as per above, when browsing to the new Magento 2.4 install at code.printivart.com.au the following Nginx error is received:

2020/10/03 03:44:33 [error] 9070#0: *22 FastCGI sent in stderr: "PHP message: PHP Fatal error:  Uncaught Zend_Cache_Exception: cache_dir "/opt/magento/public_html/var/page_cache" is not writable in /opt/magento/public_html/vendor/magento/zendframework1/library/Zend/Cache.php:209

Even when setting /opt/magento to permissions 777 the above error is still received.

Do you have any idea what the cause of this error may be?

Edit: Incase it helps, here is the Nginx server block config:

/etc/nginx/conf.d/code.printivart.com.au.conf

    include snippets/letsencrypt.conf;
    return 301 https://code.printivart.com.au$request_uri;
}
