Hi @dineshprim
The owner of the Magento file system: Must have full control (read/write/execute) of all files and directories.
Must not be the web server user; it should be a different user.
The web server user must have write access to the following files and directories: var,app/etc pub (and probably new in 2.2.x ) generated directories.
In addition, the web server's group must own the Magento file system so that the Magento user (who is in the group) can share access to files with the web server user. (This includes files created by the Magento Admin or other web-based utilities.)
I recommend setting the permissions as follows:
770 permissions is required for all the directories.
770 permissions give full control (that is, read/write/execute) to the owner and to the group
and no permissions to anyone else.
All files have 660 permissions.
660 permissions mean the owner and the group can read and write but other users have no permissions.
You should set as bellow recommended.
cd <your Magento install dir>
find . -type f -exec chmod 644 {} \; // 644 permission for files
find . -type d -exec chmod 755 {} \; // 755 permission for directory
find ./var -type d -exec chmod 770 {} \; // 770 permission for var folder
find ./pub/media -type d -exec chmod 770 {} \;
find ./pub/static -type d -exec chmod 770 {} \;
chmod 770 ./app/etc
chmod 644 ./app/etc/*.xml
chown -R :<web server group> .
chmod u+x bin/magento
Hope it helps !
