Re: Multiple http servers for zendphp7

Kevin could you provide references to what you mean by the acronyms SAN and SNI?

San is a function of the certificate, not the server, so any server that
can present a certificate should support it. All modern browsers should
support san certificates, so if your websites are all running one code
base and it is the only codebase you need on your server, san should
work. We only tried to use it once, and it wasn't served off the IBM i.
We ended up having to scrape the certificate however because the vendor
connecting to us required the domain to match the common name. That was
a while back, and I'm not sure if they still require that, but we just
renew the certificates when they expire now, and haven't tried to
combine them again.

Virtual hosts have been around for a long time. They allow one server
listening on one ip:port combination to have different configurations
based on the domain being served. For a long time SSL sites were limited
because of the timing of serving the certificate. You were limited to
one certificate per server. SNI allows you to overcome that. It moved
just enough of the headers outside the encrypted portion of the
communication to allow a server to determine what site the client is
trying to reach, and allows the server to have different configurations
(including different certificates) for each domain being served.

With SAN you have one server serving one certificate for multiple
domains. You are limited to one configuration including codebase,
certificate, permissions, etc.

With named virtual hosts and SNI, you have one server serving multiple
configurations. You can use the same or different codebases,
certificates, permissions, etc.

Both have strengths and weaknesses. Once you get past your deadline,
fire up a linux VM and create some letsencrypt certs and play around
with both just so you understand the config and routing.

Ok this is well above my skill level!

I had to look SNI up to find it is Server Name Identification

I have a single PHP application running on IBMi at 7.2 and 7.3 that is

used by

multiple entities and each entity requires a https connection with
appropriate ssl certificate.

I have a deadline of 1st Feb to get this operational.

There is such a certificate as a SAN but getting specific information

on this is

seeming difficult. I tried calling the US and UK offices of GeoTrust

and after

10 minutes + on hold to each I left a message and no replies as yet.

And I can not find anything that specifically indicates this is

supported on

IBMi.

While not totally great I can do this with a simple wildcard

certificate and just

put the entities accessing the site; for example

fredsaccounts.msd.net.au

and acmeaccounts.msd.net.au ... Etcetera.

Kevin: Thanks for the apache config - I will at some stage go through

this in

detail and try and understand exactly what you are saying - like I

said this is

way above my current skill level. Sorry but I really do not

understand what

this is doing, it may be the perfect solution for my but I can't

visualise the

network diagram or traffic flow.


Pete: I have read a lot about reverse proxies in this blog but again

until you

actually work with one it is my old head that is struggling with the

concept. I

know nothing of letsEncrypt Ok scratch that they are a free

Certificate

provider WOW I will have to investigate this further in the future.

So I am

struggling with the overview of how a reverse proxy will allow me to

have

multiple certificates as indicated above in what I am trying to

achieve. As

much as I would love to be going to Sam Antonio this year just not in

the

budget (I did Orlando last year) but if you want a guinea pig to test

your

presentation on I can definitely assist :-)

So I am a little bit stuck.

Appreciate the assistance

SNI works fine with zendserver on the i. I've been configuring apache

servers

for so long, that I just do it now, and haven't had to look around for

any kind

of instructions lately. Any basic walkthrough for setting up named

virtual

hosts should work. To answer your other question about multiple
certificates. I'm 90% sure that I had it working, but that was several

years ago,

and the memory is fuzzy. I could try again real quick to see if it

works. There

are a couple of directives in the IBM apache implantation that are

different

from standard, and one of them controls the certificate used.

SSLAppName

points to a name in the DCM which controls which certificate is used.

As I

recall the only confusing thing was getting the application set up in

the DCM.

If you have issues setting it up, I can create a letsencrypt cert and

try and pop

a new named instance on my box. It would probably be tomorrow before I
can do that however. Here is my current apache config with several

named

hosts running different code bases.

Subject: [WEB400] Multiple http servers for zendphp7

I am trying to find a cheat sheet or step by step instructions to

have

multiple

http servers all running php.

Reason being I have 4 different domain names and to enable ssl on

each

I

need 4 http servers on 4 different ip addresses.

I am also exploring SAN ssl certificates but want to explore both

options first.

Does anyone have multiple http servers providing php and are there

any

concerns / problems that I should be aware of ?

Thanks for any assistance

IBMi V7R2 and V7R3
