How to give permission to write joomla configuration?

Question

Nginx

There are two sites, one fresh is only being built #1, the second is moved from the IIS server #2. when trying to log in to the admin panel of site No. 2, it writes an error cannot write to log file . and in the admin panel of site No. 1, when saving the parameters, the error Could not write to the configuration file.
on site #1:
-fixed the paths to the log, tmp folders in the configuration.php file - result 0
-granted permissions 777 -result 0
-tried to give permissions to the whole folder of the site -result 0
on site #2:
-granted permissions 777 -result 0
-tried to give rights to the whole folder of the site - result 0
created a group, added a user to the group, tried to add root to the same group and give full rights to folders - result 0
Maybe you need to give apache permissions? how can the situation be corrected? give permission like this chmod -R 777 /var/www/html/site1
