mod_lsapi... How can I tell if its working?

[david]

Sorry if this sounds like a stupid question. CloudLinux has been working great for me for some time.

Im pretty confident Ive followed the install instructions for mod_lsapi correctly (having read the online docs several times), and I have enabled it for all domains. Following the documented installation steps. Ive added the recommended suhosin config php.ini, and then set it up for native PHP using the following commands:

/usr/bin/switch_mod_lsapi --build-native-lsphp
use/usr/bin/switch_mod_lsapi --setup
cagefsctl --force-update
service httpd restart

So... How am I supposed to know if its actually working?

Am I supposed to see something to the efftect "lsphp"-like processes showing up when running top? Because Im not seeing that.

Im on CloudLinux v6.6 WHM v11.50.10 Apache 2.4 PHP 5.5

Secondary question: Is mod-lsapi compatible with xcache?

Hello,

1) yes, after installation should appears lsphp processes. You should run: switch_mod_lsapi --enable-global (or enable mod_lsapi for single domain) and after service httpd restart:
/usr/bin/switch_mod_lsapi --build-native-lsphp
use/usr/bin/switch_mod_lsapi --setup
switch_mod_lsapi --enable-global
cagefsctl --force-update
service httpd restart

2) Yes, mod_lsapi compatible with xcache

"setup" command is responsible only for preparation for mod_lsapi (global or single domain mode).

[david]

OK... as instructed, the following commands ran successfully:

/usr/bin/switch_mod_lsapi --build-native-lsphp
use/usr/bin/switch_mod_lsapi --setup
switch_mod_lsapi --enable-global
cagefsctl --force-update
service httpd restart

Ive edited /usr/local/apache/conf/conf.d/lsapi.conf to have the following:

lsapi_backend_connect_timeout 3600
lsapi_backend_connect_tries 10
lsapi_backend_children 20
lsapi_backend_pgrp_max_idle 30
lsapi_backend_max_process_time 300
lsapi_debug Off

Im still not seeing lsphp processes. What other steps are involved?

You could check a site using phpinfo.
create a phpinfo.php file with just a <?php phpinfo(); ?> in it.
browse it. You should see
Server API LiteSpeed V6.7.1

[alexey.com.s]

Hello,

As I understand output of lsapi.conf above is not full.
can you show output of command:
cat /usr/local/apache/conf/conf.d/lsapi.conf

full file content.

if phpinfo shows not LiteSpeed V6.7.1 - in this case need deeper investigation, write please to helpdesk.cloudlinux.com

[david]

phpinfo shows LiteSpeed V6.7.1
