[users@httpd] Apache and PHP-FPM error
After implementing Apache 2.4 and PHP-FPM with the default settings we found that our system cpu usage went up significantly over what mod_php used for the same amount of web test traffic from "ab"
So we read a bit about tuning PHP-FPM and from this page ...
https://wiki.apache.org/httpd/PHP-FPM
We decided to put this ...
ProxyPassMatch ^/(.*\.php(/.*)?)$ unix:/var/run/php-fpm/php-fpm.sock|fcgi://127.0.0.1:9000/usr/local/apache/utk/docs/
into the httpd.conf file. In order to use the unix domain socket (UDS) approach as a possible solution to reducing the big spike in cpu usage.
However we get this error when do a configtest on Apache ...
AH00526: Syntax error on line 431 of /etc/httpd/conf/httpd.conf:
ProxyPass URL must be absolute!
Any suggestions on the above error?
Any tips on tuning Apache/PHP-FPM ?
Thanks

We will check it.
We use collectd to view full cpu usage. The user cpu usage is much lower
than prefork but the system cpu usage has increased significantly with
PHP-FPM. Pushing the total cpu load to ~90% frequently.
We have gone with the default settings for PHP-FPM.
This particular box has 16 cores and 48 GB RAM.
We are also using Event MPM.
We are not as familiar with how the threaded MPMs work as with prefork. So
we have just left the MaxRequestWorkers 400, etc. for the time being.

I doubt the lack of UDS, and having to use FCGI over TCP/IP is what is
causing your load spikes compared to running with mod_php.
More likely you need to tune the PHP-FPM side to start (+limit) the
appropriate number of processes appropriate for your workload and
available resources. A common cause of poor req/s is trying to service
too many requests simultaneously, ie starting 100 FCGI workers on a 2
CPU server.

Since we want to stick with what is available via "yum" for Red Hat 7
Thanks for the info

What release of 2.4? The UDS stuff wasn't there from the beginning.
