New debian SSD Server

Just build an new debian server with SSD installed, here is some optimization:

1.Disable swap

2.Enable dealine scheduler

apt-get install sysfsutils
echo "block/sda/queue/scheduler = deadline" >> /etc/sysfs.conf

test at reboot:

cat /sys/block/sda/queue/scheduler

3. Mounting SSD filesystems

# cat /etc/fstab
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
