Is it possible or will it be possible to have PHP processes on the external server? I mean TCP/IP communication between lshttpd and lsphp.

I'm sure secondary server for PHP should have the same homedirs replicated by admin but this is not problem.

Yes, you can use TCP for the socket between web server and lsphp.

lsphp -b <TCP_SOCK>

can start lsphp on the second server from command line, you need to set related environment variables first to control many lsphp children processes can be started.

Nice to hear. I can run lsphp listening on any port without problems. But I can't see there how to set "External Applications" in LSWS admin panel to make it able to connect by tcp/ip to remote lsphp. I've tried to give IP and port number in "Address" column but it is not enought. LSWS still users local lsphp.

Best regards,

Thank you for advise, now I see the difference. Lshttp doesn't try to run local lsphp by socket any longer so that is good. Just for test I have my lsphp runned on the local machine as TCP/ip server. But all of my websites are blank (Alert!: Unexpected network read error; connection aborted) or I've connection timeout.

Additionally I can't see any network traffic on port 3000 (where my lsphp is listening to). Sory for such questions but I can't see any complex howto about running lsphp as external tcp/ip server for LSWS.

Nothing special in LSWS error logs.

Your need to change the "Address" of lsphp external app to "IP:port", do you?

Yes, I do.
Name lsphp5
Address 1.2.3.4:3000

Where 1.2.3.4 is my address. I can telnet to this IP on port 3000.

I found something else in logs. I've got this at any refresh of website (website is blank):

It wont work with PHP suEXEC, as each suEXEC PHP process need its own listening socket, has to be "Auto start" using "Unix domain socket".

Thank You. I am able to run this without suexec, but I thought there is possible to run lsphp in suexec mode for multiuser environment like directamin with only one instance of tcp/ip listener.

There is too wasting for us to run at least one lsphp -b process for each system user and too insecure for us not to use suexec.

Anyway thank you for all help.
