A brief introduction of zypper

After installing SUSE (my version is SLES 12), the CD/DVD will be added as a default repository:

linux-uibj:~ # zypper repos -d
# | Alias       | Name        | Enabled | Refresh | Priority | Type  | URI                                                         | Service
--+-------------+-------------+---------+---------+----------+-------+-------------------------------------------------------------+--------
1 | SLES12-12-0 | SLES12-12-0 | Yes     | No      |   99     | yast2 | cd:///?devices=/dev/disk/by-id/ata-VBOX_CD-ROM_VB2-01700376 |       

So after you insert the installation ISO file into CDROM, use zypper in command can install the software:

linux-uibj:~ # zypper se systemtap
