Setup Apache ec2-user permission on Amazon Linux

Add your user (in this case, ec2-user) to the apache group.

[ec2-user ~]$ sudo usermod -a -G apache ec2-user

Log out and then log back in again to pick up the new group, and then verify your membership.

[ec2-user ~]$ exit

To verify your membership in the apache group, reconnect to your instance, and then run the following command:

[ec2-user ~]$ groups 
ec2-user adm wheel apache systemd-journal

Change the group ownership of /var/www and its contents to the apache group.

[ec2-user ~]$ sudo chown -R ec2-user:apache /var/www

To add group write permissions and to set the group ID on future subdirectories, change the directory permissions of /var/www and its subdirectories.

[ec2-user ~]$ sudo chmod 2775 /var/www && find /var/www -type d -exec sudo chmod 2775 {} \;

To add group write permissions, recursively change the file permissions of /var/www and its subdirectories:

[ec2-user ~]$ find /var/www -type f -exec sudo chmod 0664 {} \;
