For this sort of thing, I assign a second IP address to the machine, then configure everything to bind to that IP address (making sure the original implementation binds to the first IP address only). For apache and the modules, you can just create separate source directories, and designate a unique target for installation. You might want to make the target match up with the version of Apache. I.e. make the target for the new one "/usr/local/apache1.3.12". As long as the source is also separate from the production source, the modules should slide in without touching anything else. Change the configuration to point at your production document dir and script dirs, or create new document and script dirs if you're ultra paranoid. Test out on the second IP address all you want. While the server will be running on the same machine (and that presents a little bit of risk exposure), it'll be a separate instance with separate files and everything. When it comes time to move to production, shut down the test server. Change the conf file to bind to the primary address. Then, in quick succession, stop the production server and start the new server. Change over (hopefully). The trick is to start using versioned target directories for your stuff. Instead of just cramming it all in /usr/local/bin, set up /usr/local/apache1.3.12/bin etc. doug On Wed, 19 Jul 2000, Keith Kwiatek wrote: > Hello, > > I have a production system (solaris 7) with apache 1.3.6 system with > mod_perl.1.19 and mod_ssl.2.3.1 > > I would like to somehow install the latest apache + mod_perl + mod_ssl + > DBI/DBD versions on the production system, BUT without interrupting the > current production system.
