backend2.floss.my.id
do
   ssh root@"$i" yum install nginx -y;
   ssh root@"$i" "systemctl enable nginx && systemctl start nginx";
   ssh root@"$i" yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm -y;
   ssh root@"$i" yum-config-manager --enable remi-php72;
   ssh root@"$i" yum -y install php \
               php-intl \
               php-common \
