Trying to use APC but it seems to be clearing out?

I'm running 4.1.1 and it exists every hour or so too without reason.


Anyways guy try this

We got child procs to 4 (half of cpu's, we have muti-client using php so we dont want them overtaking all cpus by 1 proc on accident randomly)

max req per proc on php is 2500, 5000 caused one proc to do 90% cpu roughly on some clock strace I thought I posted the error here but seems I forgot (was tired, sorry nitewave

2000/2500 seems nice. XCache caches decent, php process idle time is 120 seconds so it's hopefully one of the 4 possibly spawned per 20 or so vhosts is active. Ram seems okay barely swap on a 10gb system with high mem tuned mysql with 16gb of db's

I've been experiencing cache clearing as well. I have configured Litespeed to let PHP/LSAPI to self-manage its instances:

Instances: 1
Suexec: on
Max connections: 64
PHP_LSAPI_CHILDREN=64
LSAPI_CHILDREN=64

From my experience with PHP-FPM (where opcode caches work perfectly) the process tree in litespeed should work as:
- lshttpd
-- lsphp5 process manager
--- lsphp5 (as user example1 - child process)
--- lsphp5 (as user example1 - child process)
--- lsphp5 (as user example2 - child process)
--- lsphp5 (as user example2 - child process)

where the lsphp5 process manager spawns lsphp5 processes running as suexec user example1 and example2 depending on the requests served and each one of them can read/write the process manager's shared memory segment that caches both example1 and example2 user files.

What I get on Litespeed is no lsphp5 process manager and many example1 processed that each one of them run their own mmap cache segment which in turn constitutes any opcode cache useless.

We *need* an operational opcode cache mechanism on Litespeed! Please fix it!

since you set

Suexec: on

lsphp is not in self-manage mode.

any opcode cache useless.

when php suExec enabled, only eAccelerator able to share opcode cache between processes, since the opcode cache is saved on disk.

[priestjim]

This should be then a feature request then, since with suexec disabled PHP is pretty much useless in a shared environment.

FYI, nginx + php-fpm operates EXACTLY as fastcgi + opcode cache should.

[mistwang]

that feature is on our to-do list. no ETA yet.

hello, how to know
xcache, apc, eacelarator is actif ?
any advice ?

1. create a phpinfo page like

echo "<?php phpinfo(); ?>" > /path/to/file/named/phpinfo.php

then point browser to that file and see if you have these listed.

or

2. run command line

/usr/local/lsws/fcgi-bin/lsphp5 -i | egrep -i 'apc|xcache|eaccelarator'

if nothing comes up, then none of them is compiled in lsphp.

what a command to compile it ?

[webizen]

They are not part of php source so you can NOT do --enable or --with to compile them. Refer to their own document for compile/install with php.

eAccelerator: https://eaccelerator.net/wiki/InstallFromSource
APC: http://www.php.net/manual/en/apc.installation.php
xCache: http://xcache.lighttpd.net/wiki/InstallFromSource

there is true ?
