Please help: Nginx config for Drupal + APC + Php + FPM

johntang's picture

Hello there,

I use OpenVZ with 4 CPUs and 4GB RAM on Redis 6 (Final). I running Drupal 7 using perusio config and seem the site is load slowly.

My server is using Nginx PHP-FPM, APC, Redis.

These are my config for PHP-FPM:

pm.min_spare_servers = 5
pm.max_spare_servers = 10
pm.max_requests = 200

slowlog = /var/log/php-fpm/www-slow.log

php_flag[display_errors] = off
php_admin_value[error_log] = /var/log/php-fpm/www-error.log

It will be tough to give you

It will be tough to give you an answer based on just your configuration.

Have you tried determining what the bottleneck is?

Is it the database? Is it the webserver? Do you have a large number of logged in users or is most of your traffic anonymous? How many modules do you have enabled? Are there certain pages that load faster than others?

Do you have lots of views? Have you enabled caching?

Bhosmer, Thanks for your

johntang's picture

Bhosmer, Thanks for your reply.

My traffic is about 100 per day, I user mysql 5.1, PHP 5.3. Our site almost using Views. The main modules used is:

Search API
Views
Views PHP
Views Slideshow
Microdata
Microdata
Redis
Entity cache
Metatag
Omega Tools
XML sitemap
Views Content Cache

Through debugging, I see the bottleneck on Views module.
Beside Drupal, I have use Vanilla forum, but it very fast than Drupal.

Thanks
John

How did you determine it was

bhosmer's picture

How did you determine it was the views module that was your bottleneck? You might check out the High Performance group for some good information.

I'd start by analyzing your database performance using mysqltuner.pl and some other tools.

Check the slow query log

perusio's picture

activate it in your MySQL/MariaDB setup. Just a side comment. It makes no sense in your php-fom config to use UNIX sockets and then constrain the clients. By definition UNIX sockets are local things that are tied to a particular file system. So just comment it out.

Check for something like:

# Error logging goes to syslog due to /etc/mysql/conf.d/mysqld_safe_syslog.cnf.
#
# Here you can see queries with especially long duration
log_slow_queries        = /var/log/mysql/mysql-slow.log
long_query_time = 2
log-queries-not-using-indexes

The above logs all queries tqking more than 2 seconds and not using indexes.

100 visits per day is a small site. You might tune your MySQL server setup a little bit. Starting by the InnoDB pool size. Make it be at least 75% of your server RAM. In your case 3G.

I used Devel module for

I used Devel module for determine the bottleneck, and I'm sure Views is caused.

My current innodb buffer pool size is 1GB, I think it normally. And log_slow_queries I'm also tried some time before But it not log anything :(.

@perusio: Your suggestion is using TCP instead of UNIX php-fpm.sock?

Other ideas?

Any suggestion for slow logs?

Start With the Slowest

mesch's picture

It's tough to remotely diagnose this without all the details, but here are a few thoughts:

  1. If you're quite sure MySQL queries are the cause, then start with the slowest and/or most common recurring entries in the slow log.

  2. You say that you believe the problem is with Views, and further up you note Views PHP is enabled. Make sure you aren't doing anything with Views PHP that would slow things to the extent you're seeing.

  3. I see in the log a lot of entries pertaining to various "GDN" table operations. Revisit any custom module table schemas to make sure they're indexed/optimized.
