Heroku & PHP
Sponsored by Heroku Not.
Christoph Hochstrasser @hochchristoph github.com/CHH Blog: christophh.net Full-Stack Web Developer –
Funemployed Contributor zu Composer, StackPHP. Creator von php-build.
Um was gehts? • Was ist Heroku? • Das Problem
mit Heroku und PHP • Buildpacks & Open Source to the rescue! • Rezepte für PHP Apps auf Heroku
Heroku? Wat?
None
her-OH-koo
Platform as a Service
Ruby, Python, Node.js, Java, Scala, Clojure, Go
(PHP) dazu später mehr
Dynos
Addons addons.heroku.com
„Buildpacks“
12factor.net
PHP
PHP Support auf Heroku ist „solala“
Problem:
PHP 5.3 + Apache Prefork MPM & mod_php + Dynos
haben nur 512MB RAM
Aber das können wir beheben. Let’s do it.
Buildpack • Erlaubt die Verwendung eines eigenen Software Stacks auf
Heroku • Pro App • Git Repository • Scripts (detect, compile, release) • Binaries von z.B. S3 • Mehr unter https://devcenter.heroku.com/articles/buildpack- api
Buildpack git push heroku master detect compile release
Darf ich vorstellen: github.com/CHH/heroku-buildpack-php
Inspiriert vom Node.js Buildpack
Moderner PHP Stack
PHP-FPM & NGINX
PHP 5.3, 5.4, 5.5 dynamisch konfigurierbar
Zend Opcache
mongo redis intl pgsql apcu + more to come
<?php phpinfo(); ?> https://chh-php-test.herokuapp.com/info
Composer
Unterstützt Symfony 2, Silex & Slim Wordpress (mit Anpassungen) In
Zukunft auch Zend Framework 1/2 & Laravel
NewRelic Monitoring
Konfiguration über composer.json
{ "require": { "php": ">=5.3.0", "silex/silex": "~1.0@dev", "ext-libevent": "*" },
"extra": { "heroku": { "document-root": "web", "index-document": "index.php", "php-config": [ "short_open_tag=on", "date.timezone=Europe/Vienna", "newrelic.appname=php-test" ], "engines": { "php": "5.4.*", "nginx": "1.4.*" }, "compile": [ ] } } } Framework php.ini Einstellungen Stack Versionen Shell Befehle Häufige Settings
„Zeroconf“ Symfony 2 Support
$ php composer.phar create-project symfony/framework-standard-edition Symfony 2.3.0 $ cd Symfony
$ heroku create —buildpack git://github.com/CHH/heroku-buildpack-php —region eu $ git push heroku master
Help Wanted! ! github.com/CHH/heroku-buildpack-php/issues
Rezepte
Lokales Development
php -S php app/console server:run
Credentials
Config Vars $ heroku config:set API_SECRET=mytotallysecretkey $_SERVER['API_SECRET']
+ änderbar ohne Code Push + nicht eingecheckt im Repository
Kandidaten für Config Vars: • S3 Bucket • Amazon Access
Key/Secret • Datenbank Host, Port, Username, Passwort, Datenbankname • Redis Host • Secrets aller Art (Facebook,…) • Application Environment
Aber wie mach ich das lokal?
.env github.com/vlucas/phpdotenv
AWS_SECRET_KEY=foo AWS_ACCESS_KEY_ID=asd8asd8ausd MY_AWESOME_CONF_VAR=foobarbaz DATABASE_URL=mysql://root:pass@localhost:6657/dbname SERVICE_URL=localhost:5000 REDIS_URL=redis://localhost:6379 REDIS_PASS=s3cr3tp4ss SERVER_NAME=localhost:3000 APP_ENV=development
Assets
JS/CSS/Images → S3 → CDN
Alternative php app/console assets:dump —env=prod
{ … "extra": { "heroku": { … "compile": [ "php
app/console assets:dump —env=prod" ] } } }
Sessions
Redis $ heroku addons:add redistogo
Datenbank
Heroku Postgres heroku addons:add heroku-postgresql
MySQL: Amazon RDS heroku addons:add amazon_rds
MongoDB $ heroku addons:add mongohq
