Resolved Can't locate API module structure `pagespeed_ap24_module'

[Tomek]

Hi,

on the fresh install of Plesk I wanted to turn on "pagespeed_ap24" module, but I got this error:

Template_Exception: httpd: Syntax error on line 56 of /etc/httpd/conf/httpd.conf: Syntax error on line 78 of /etc/httpd/conf.modules.d/00-base.conf: Can't locate API module structure `pagespeed_ap24_module' in file /usr/lib64/httpd/modules/mod_pagespeed_ap24.so: /usr/lib64/httpd/modules/mod_pagespeed_ap24.so: undefined symbol: pagespeed_ap24_module

Apache does not want to turn on.


I installed Google PageSpeed module from this extension dashboard:
Google PageSpeed Insights - Plesk Extensions


BTW, what is the difference between pagespeed and pagespeed_ap24?

Hello,

if you have installed pagespeed module with the Plesk extension, you should not need to enable another apache module.

mod_pagespeed_ap24 is for Apache 2.4 , when mod_pagespeed is for Apache 2.2

Thanks Virtubox

weird, I have Apache 2.4:

httpd -v
Server version: Apache/2.4.6 (CentOS)
Server built: Oct 19 2017 20:39:16

so i'm confused now.

ok, I probably know what i'm doing wrong.

When I select checkbox, I turn off or turn on module?

Same issue. I have Apache 2.4 but when I check pagespeed_ap24 I receive this error
httpd: httpd: Syntax error on line 56 of /etc/httpd/conf/httpd.conf: Syntax error on line 78 of /etc/httpd/conf.modules.d/00-base.conf: Can't locate API module structure `pagespeed_ap24_module' in file /usr/lib64/httpd/modules/mod_pagespeed_ap24.so: /usr/lib64/httpd/modules/mod_pagespeed_ap24.so: undefined symbol: pagespeed_ap24_module
Any suggestion?

Any suggestion?

Most probably loading of pagespeed_ap24_module is defined twice in Apache configs. Check it with

# grep -ilr "mod_pagespeed_ap24.so" /etc/httpd/

You may have something like

# grep -ilr "mod_pagespeed_ap24.so" /etc/httpd/
/etc/httpd/conf.modules.d/00-base.conf
/etc/httpd/conf.d/pagespeed.conf

In this case just comment line

LoadModule pagespeed_ap24_module /usr/lib64/httpd/modules/mod_pagespeed_ap24.so

in /etc/httpd/conf.modules.d/00-base.conf file and restart httpd service.

Yes, indeed pagespeed.conf checks version and loads the proper module for apache 2.4.
The issue is in the module selection in Plesk (Apache settings), when I uncheck pagespeed and check pagespeed_ap24, Plesk try to load both modules. If pagespeed.conf load the proper version, the Apache settings should not show the pagespeed_ap24.
Thanks
