Installing Drupal with PHP-FPM

Posted by Anonymous on April 5, 2014 at 6:57pm

Running into all sort of problems after trying to configure Drupal 7 to run on PHP-FPM on CentOS 6.2 Apache 2.2 this week.

I was reviewing @kbahey 2bits.com excellent article on configuring Drupal to run with fcgid and I was wondering if we could use that as a starting point to explore a PHP-FPM deployment.

I am getting a series of timeout/server 500 errors in my httpd/logs/error_log such as these after install:

Introduction

PHP Frameworks are becoming more and more complex, specially now that almost all of them are fully object oriented. In serious applications huge amount of code needs to be interpreted and loaded into the memory for every request, it's a needles waste of huge amount of resources.
But what if we could serve requests not by using traditional request/response method but by using sockets and asynchronous calls?

Understanding and optimising a slow mysql query (views)

Posted by foxtrotcharlie on April 18, 2014 at 1:43pm

I have a views query that is my number 1 slow query. I have been trying to understand why it's slow and what to do about it, but I am struggling. So far I think that it's slow because it's using temporary table and a filesort, as shown in the 'Explain'. When I remove the 2nd "ORDER BY" statement (node_data_field_opportunity_closing_date_field_opportunity_closing_date_value ASC), no temporary table is used the query time is significantly reduced.

Is there a way to keep results ordered without generating a temporary table? Any other tips on this query would be appreciated :-)

Need advice for faster Drupal website

Posted by satvision83 on April 29, 2014 at 12:35pm

Hello everyone.
I have a website for ads.
This is the url: www.4sport.bg

It's hosted on Managed VPS with 4gb ram.

I'm not caching it with the standard procedure from here: admin/config/development/performance, because the website has registered users that will be able to create an ad, update their ads, view their profiles etc, it's very dynamic so I needed something better to cache.
The website is not fast as it should. It usually loads more than 1300ms.

I'm using PHP APC and you can see it from here: www.4sport.bg/apc.php

Scaling a drupal site to handle 1000 authenticated reqests per second

Posted by ktrev on May 3, 2014 at 7:54am

      We are planning to make a Learning Management System with drupal.We have created a site which can run a single course at a time.

There are 84 modules installed in the site.

Our aim is to handle 1000 authenticated requests per second.
(This can be viewing the site or adding content to the site)

Our server details are as follows:
(this is a vm on one server)

Memory : 16GB
Processor: 8 core
OS: Ubuntu
Webserver : Ngnx
We have php-fpm with maria db as database server

We have installed APC and Memcache in the site.

varnish purge cache all the time

Posted by alexus on May 7, 2014 at 5:13pm

I'm constantly seeing following line in my syslog'

varnishd[2826]: CLI telnet 192.168.XX.XX:60069 172.16.XX.XX:6082 Rd purge req.http.host ~ XXX.XXX.XXX && req.url ~ "/"

and it doesn't seems like someone does it manually all the time either...

I'm able to confirmed that cache is actually is purging at every request and i'm on clean slate (in terms of cache) after purge is done.

how would one troubleshoot something like that?

High cpu usage in webserver

Posted by ktrev on May 12, 2014 at 5:10am

We have separate machines for database server and web server (each with 8GB RAM and 4 cores)
The user CPU% of web server is around 60-70% (when you run a jmeter test that login 100 users)
In database server its less than 5%.
We have Apache with php5-fpm.By top command we can see that each php-fpm process is taking more than 20% of CPU

Memcache and Apc are on web server itself.Why is the CPU usage this high ?

PHPNG Being Tested In PHP 6

Posted by Jamie Holly on May 12, 2014 at 3:20pm

Just noticed this interesting post about Facebook's PHPNG being tested in the PHP6 branch. Of course it's really early, so there is no way of knowing if it will actually be included in a future release of PHP, but it is something to keep an eye on:

Drupal 6 Site Offline Template

Posted by alexus on May 15, 2014 at 8:18pm

... every once in a while users are getting "Site Off-Line" message when trying to access Drupal6 (Pressflow), so I start looking into following document to modifiy template and possibly provide me with a reasoning on why Drupal keeps doing that..

Theming the Drupal maintenance page | Drupal.org

What should be included into new template page? I was thinking at least this one:

PHP: mysqli::$connect_error - Manual

but what else would be useful in order to troubleshoot site offline??

Minimizing Bootstrapping.

Posted by brad.curnow on May 19, 2014 at 12:37pm

Hi Everyone!

I've written a PHP page that sits inside my Drupal install and is used for split second traffic processing and directing. Pending certain conditions (carried as POST data in the url) the script progressively bootstraps Drupal.

For instance we first look to see if we can direct the user to a cached page. If not, we bootstrap to DATABASE and run a couple of simple queries to see if we need to direct them to somewhere else.
