NSIS - nullsoft scriptable install system 2.46

Recently I was tasked with automating the installation of a few customized applications. As a requirement for my production site, I must always have the most up to date version of the following:

• Apache Web Server (HTTPD) 2.2.21
• OpenSSL 1.0.0e
• PHP 5.3.8
• Java Runtime 1.6
• ElasticSearch 0.17.1
• Databases supported MySQL, Oracle, MS-SQL Server (various php extensions needed)
• Custom PHP Web Application w/ ExtJS 4.0.6

Maintaining the updates for these products can be a pain when you do not have access to the production system. My original Install guide was quite lengthly and was a pain to keep up to date everytime my installation procedures changed. I was able to fix all of this will Nullsoft's NSIS.

There are a variety of plugins available to help with different tasks. Currently my Installer uses a splash screen, modifys system variables, creates and starts windows services, and uninstalls everything cleanly.

Splash Screen - Just Modify the Splash.bmp's Absolute path in quotes. Add to the NSI file just before you Installer Information. (Name, Outfile, installDir, etc.)

;====================================================

;Splash Screen Information

Function .onInit

SetOutPath $TEMP

File /oname=spltmp.bmp "C:\Users\Charles\Desktop\Splash.bmp"

advsplash::show 1000 600 400 -1 $TEMP\spltmp

Pop $0 ; $0 has '1' if the user closed the splash screen early,

; '0' if everything closed normally, and '-1' if some error occurred.

Delete $TEMP\spltmp.bmp

FunctionEnd

If you want your installer to run with elevated Privledges (Vista, Windows 7)

Check the nullsoft site for downloads and additional information. I used the nsSCM & nsEXEC plugins for manipulation of window's services and other batch script tasks.
