On the weekend I plan on upgrading Nessus 2.2.3 to Nessus 2.2.5 on a
RHEL 3 machine and I need to have a viable backout plan. In that
regard, is there a way to have a slotted installed (i.e. keep Nessus
2.2.3 incase Nessus 2.2.5 does not run properly)?
This shouldn't be a problem if you run e.g.
./configure --prefix=/usr/local/nessus
for all the packages that need to be installed (nessus-libraries, libnasl,
nessus-core, nessus-plugins). All files will be installed into that path
and your existing nessus files will not be touched. Before running make
install you can check where files will be put by doing make -n install.
One problem you may encounter is that the new nessusd binary
(/usr/local/nessus/sbin/nessusd) may try to use the previous version's libs.
if you run
/usr/local/nessusd/sbin # ./nessusd -d
And it lists an older version number for the libraries, then this problem has
occured - it can be solved by setting
export LD_LIBRARY_PATH=/usr/local/nessus/lib
before launching nessusd.
