Good old days

Version control

Versioning concepts

Symlink switch oldpath/to/webapppath/to/webapp-1.0.2 -> path/to/webapppath/to/webapp-1.0.3

Symlink switch newpath/to/webapppath/to/webapp-1.0.2path/to/webapp-1.0.3 -> path/to/webapp

Automated deployment

Concept: build• required steps•- to “build” an application validate - test - document - package

All tools needed!

Phing• build tool written in PHP• comparable to ANT build scripts• impressive list of task templates• extensible for missing tasks

Phing HelloWorld!<?xml version="1.0" encoding="UTF-8"?><project name="demo" default="build"> <target name="build"> <echo msg="Hello World!"/> </target></project>

Export from SVN<property name="buildpath" value="./build"/><property name="repopath" value="https://svn.myserver.com/demo/trunk"/> <target name="prepare"> <delete dir="${buildpath}" includeemptydirs="true" quiet="true" verbose="false" failonerror="false" /> <mkdir dir="${buildpath}"/> </target> <target name="getsources" depends="prepare"> <svnexport svnpath="/usr/bin/svn" force="true" nocache="true" repositoryurl="${repopath}" todir="${buildpath}"/> </target>

Anywhere deployment

Deployment options• platform (windows, linux, i5, …)• database engine (mysql, ms sql, oracle)•- deployment protocols rsync - FTP

Linux server

Example deploy Linux<target name="deploy-linux"> <exec dir="./build" command="rsync -rq user@server.com:/srv/www/demo"/></target>

Windows server

Deploy to windows<target name="deploy-windows" depends="version-bugfix"> <ftpdeploy host="${env.win-prod}" port="21" username="${auth.win-prod.username}" password="${auth.win-prod.password}" dir="/" mode="binary" clearfirst="false"> <fileset dir="."> <exclude=”./library/Zend”/> <exclude=”./library/ZendX”/> </fileset> </ftpdeploy></target>

Windows Azure

A few remarks•- runs only on windows but still uses phing :-)• takes a considerable time to upload• instances are deﬁned in the conﬁg

Setting properties<property name="cmd-cspack" value="c:Program FilesWindows Azure SDKv1.3bincspack.exe" override="false"/><property name="cmd-csrun" value="c:Program FilesWindows Azure SDKv1.3bincsrun.exe" override="false"/>

Prepare for Azure<target name="prepare-azure" depends="version-bugfix">  <mkdir dir="./bldtmp" /> <copy todir="./bldtmp" overwrite="true"> <fileset dir="./deploy/azure"> <include name="**/*.*" /> </fileset> </copy> <copy todir="./bldtmp/PhpOnAzure.Web" overwrite="true"> <fileset dir="."> <include name="**/*"/> <include name="*"/> </fileset> </copy></target>

Deploy to Azure<target name="deploy-azure" depends="prepare-azure"> <exec command=""${cmd-cspack}"ServiceDefinition.csdef /role:PhpOnAzure.Web;PhpOnAzure.Web /out:PhpAzure.cspkg" dir="./bldtmp" /> <mkdir dir="./release/${phing.project.name}-${version.number}/azure-prod" /> <copy todir="./release/${phing.project.name}-${version.number}/azure-prod" overwrite="true"> <fileset dir="./bldtmp"> <include name="PhpOnAzure.cspkg"/> <include name="ServiceConfiguration.cscfg"/> </fileset> </copy></target>

Continuous Integration

Continuous Building

Considerations

Some reminders•- design your apps to work everywhere use OOP abstraction layers - use plugins - take care of sessions!• investigate “the other platform” - gives you a head start over competetion - teaches you the caveats• “cloud” solutions are in high-demand - see what works best for your customer

automate what you might forget under stress!
