Ftp Access to /var/www/html for website editing [CentOS/RHEL + Vsftpd]

1. Create a group for website users , say webgroup   # groupadd webgroup
2. give them proper permissions  : chown -R root:webgroup /var/www/html
3.chmod g+s  /var/www/html    {this will help if a user "x" creates a file/dir then it will be owned by him , so set a SETGID bit to the parent directory so that any new file by default have group id as webgroup}
4. chmod 770 /var/www/html
5. usermod -aG webgroup apache
