I have postgresql on my alpine linux distro. Boots from cd/usb, runs |
| 17 |
from RAM by default, built with hardened gentoo uclibc. |
| 18 |
|
| 19 |
Running a database itself from this setup is not that interesting, |
| 20 |
naturally enough. But alpine also ships a hardened vserver[1] kernel, so |
| 21 |
its possible to set up a disk array - lvm, raid, scsi, ide, iscsi (both |
| 22 |
target and initiator supported), sata and install your vserver(s) on |
| 23 |
disks. |
| 24 |
|
| 25 |
Now you can run the vserver host from USB or cdrom and just mount up |
| 26 |
your disk array. Combine with iscsi/lvm and you have suddnely a HA |
| 27 |
cluster with a SAN backend on comodity hardware. |
| 28 |
|
| 29 |
On your vserver guest you can run debian, standard gentoo, or alpine. |
| 30 |
(other distros might work as well but is not tested). Since alpine is so |
| 31 |
small, its possible to configure new vservers in seconds. (alpine base |
| 32 |
system is 3MB while minimal debian is 200MB?). Even if you run debian as |
| 33 |
a vserver it would be protected the by PaX'ed kernel. |
| 34 |
|
| 35 |
The alpine wiki[1] itself is running on alpine with postgres as backend, |
| 36 |
in a vserver. |
| 37 |
|
| 38 |
Unfortunally, no java at all, but it does not prevent you to run your |
| 39 |
hardened gentoo in an alpine vserver. |
