Re: [PHP-DB] MySQL - separating web and database servers
Hi Piotr,
Everyone else is suggesting edit all of the code.
Alternatively you could setup an iptables rule which forwards all
incoming requests on 127.0.0.1:3306 (or whatever port your mysql server
is running on) to 192.168.0.1:3306 (repolace 192.168.0.1 wit the IP of
your DB server).
This way if your DB moves again, you change your forward rule.
If, however, you try to put the PHP code on another system, you will
need to either put the DB on the same system, or change the iptables
ruleset for the new webserver.
It's worth a shot.

Matt Vos OK, this is how I want it, but when connecting with localhost in the connection string, unix socket is used, not the networking... It would be nice to have default_connection_with_localhost = unix_socket|loopback in my php.ini :) Even if one of them is better for most of the cases. It's good to have a choice.

Re: [PHP-DB] MySQL - separating web and database servers
What is the problem in changig localhost in houndreds of scripts, ou can do
that with a script or a good text editor that has the function Replace in
Files... can do the trick.
I dont think that editing the host file to make localhost point to the other
machine is a good practice. :)

Changing scripts is not a main factor here (but it's not as simple as it may
seem - consider some encoded php applications, cgi's or some not informed
users who will overwrite changed files with their local copies).
I just wanted to know if it's possible to do this without touching
localhost.

I agree. But it doesn't work anyway ;)

Re: [PHP-DB] MySQL - separating web and database servers
Change, in the /etc/hosts file, this:
localhost 209.10.33.12# new db server
Hopefully this will work. Haven't tested, just a suggestion. Probably
breaks a few other things, but at least mysql will work.

Re: [PHP-DB] MySQL - separating web and database servers
in your php.ini you have mysql.default_host, mysql.default_user and
mysql.default_password which are used if:
a) you are not in safe mode
b) you supply no string for those parameters.
But i guess this is not your case, i think this doesnt help, but i had an
ideia, you could set your server (http) to work as a router and make
something like a port-forwarding to the other server, like routers do, one
ip could be used be several machines, depending on the port is accessed the
data is forwarded to that port.
This is just an idea i had right now, i dont know if it can be used or if it
works but and least appears to logical and implementable.
Good luck.

PB I agree with all of the others, you should not be hacking your way around this as it will make lots of problems. You just need to tell your users to switch their scripts to using the new host.
