Can I recommend the excellent linux-vserver project? It's a bit more |
16 |
heavyweight than you were looking for, but basically makes it super |
17 |
simple to spin up what feel like fully virtualised machines. |
18 |
Weight-wise it's somewhere between a full virtualisation solution and a |
19 |
chroot (in fact it's kind of a wrapper around a chroot to make it feel |
20 |
like a full machine instance). If you are really keen though you can |
21 |
use the unification utility and effectively hard-link many jails |
22 |
together which gives you a very, very lightweight way to run up many |
23 |
instances of a process. Personally I wouldn't boot up a server without |
24 |
using at least this... |
25 |
|
26 |
If you just want to harden apache then also look at mod_security which |
27 |
can give you a chroot and also quite a decent "software firewall" that |
28 |
may well help. grsecurity (or other rbac) could additionally be used to |
29 |
constrain the damage a cgi script could cause |

Good luck |
