lsapi slave

[Clockwork]

Hello,

I would like to add an lsapi slave to one of my litespeed webservers.

Is there any guide how to do this?

The webserver itself should still process php requests, not only the slave, so that I can use the performance from both servers.

I know how to build lsapi, but I'm stuck on the configuration on my lsws.

What exact the 'slave' are you referring to? an external web application? or something else? Note that only PHP and Ruby LSAPI modules available.

I'm refering to a php lsapi that I start from command line.

a typical setup is as follows:
1. start lsphp from command line

PHP_LSAPI_MAX_REQUESTS=500 PHP_LSAPI_CHILDREN=35 /path/to/lsphp -b IP_addressort

2. setup external app (such as 'remote php') and script handler (for php handled by 'remote php' ext app) on web server.
external app:
address => IP_address: port (in step 1)
auto start => no

might be a dump questions, but do I need to copy the php files to the remote php machine?

Because I receive errors like this:

PHP Warning: Unknown: failed to open stream: Operation not permitted in Unknown on line 0

no need. however, php binary on the remote server needs proper permission to access the resource as if it runs from the web server.

I've chown'ed the /lsphp5/bin/lsphp and /lsphp5/lib/php binary to www-data:www-data, still same error.

take it back. you need to copy the file(s) to the remote server. file path needs to be the same. if web server is chroot'd, file path starts from chroot (e.g. /path/to/chroot/lsws/...) needs to be under file system root of the remote server (/lsws/...).
