NAME ^

App::installguide - App Installation Guide

INTRODUCTION ^

This is the Installation Guide to the App (Perl 5 Enterprise Environment). You can find out more background to the project on the web.

  http://www.officevision.com/pub/p5ee
  http://p5ee.perl.org

Installation of the App requires the following:

 * install Perl (at least 5.5.3) (5.005_03)
   (you can test this by typing "perl -v")
 * install Apache or other web server
 * install dependent Perl modules from CPAN
 * install App software

We will discuss the last item first, because it is assumed that most people know how to do the first three or they are already done.

SET UP THE ENVIRONMENT ^

You could just install all of the software into "/usr/local" or wherever your Perl is installed. In that case, skip this section.

If however, you are setting up a development environment, or if you wish to install multiple versions of the App software, it is advisable you choose an approach as follows.

Set Up a Development Environment (Unix)

Choose a directory that will be the base of all App environments (i.e. /usr/mycompany, any base directory will do).

  /usr/mycompany

Create a subdirectory for each separate developer/tester. You may wish to choose groups rather than users (i.e. "devel", "qagroup"). (In this case, you would have several developers working in one directory tree. This may cause more conflicts between developers during development, but the conflicts get worked out more quickly than when developers work in separate directories.)

  /usr/mycompany/spadkins
  /usr/mycompany/joe
  /usr/mycompany/marysue
  /usr/mycompany/devel
  /usr/mycompany/qagroup

These are independent development "sandboxes". Later, when we start making releases of the software (which includes the App framework), we will create other environment directories like this.

  /usr/mycompany/0.5.0
  /usr/mycompany/0.5.1
  /usr/mycompany/1.0.0
  /usr/mycompany/2.17.10

All of these directories will have their own self-contained installation of software. Named versions (i.e. "test", "qa", "prod") are simply symbolic links to the particular version to which they currently apply.

In your chosen development directory, you should set the permissions to allow access to be granted by group.

  chgrp -R spadkins /usr/mycompany/spadkins  # all files and dirs owned by group
  chmod 775 `find /usr/mycompany/spadkins -type d -print` # dirs writable by the group
  chmod g+s `find /usr/mycompany/spadkins -type d -print` # setgid bit keeps files in the group

Within each directory, you should create a default set of subdirectories.

  cd /usr/mycompany/spadkins
  mkdir src lib bin man etc include src/tar

You should set up in your ".profile" some appropriate variables.

  PREFIX=/usr/mycompany/spadkins; export PREFIX
  PATH=$PREFIX/bin:$PATH; export PATH
  LD_LIBRARY_PATH=$PREFIX/lib:$LD_LIBRARY_PATH; export LD_LIBRARY_PATH
  LIBPATH=$PREFIX/lib:$LIBPATH; export LIBPATH  # for AIX? (instead of LD_LIBRARY_PATH)
  MANPATH=$PREFIX/man:$MANPATH; export MANPATH

Note: If no initial MANPATH was set, setting the MANPATH this way could inhibit the "man" command from finding all of the standard "man" pages. You may need to create an initial MANPATH something like this and then add the $PREFIX/man directory to it.

  MANPATH=`find /usr /opt /man -type d -name man -print 2> /dev/null`
  MANPATH=`echo $MANPATH | sed 's/ /:/g'`
  export MANPATH

Note: It may be similar for LD_LIBRARY_PATH, and you may need to set an initial LD_LIBRARY_PATH something like this.

  LD_LIBRARY_PATH=`find /usr /opt /lib -type d -name lib -print 2> /dev/null`
  LD_LIBRARY_PATH=`echo $LD_LIBRARY_PATH | sed 's/ /:/g'`
  export LD_LIBRARY_PATH

Now log out and log in again so that your ".profile" variables are in your environment.

INSTALL DEPENDENT SOFTWARE ^

Install Dependent Modules from CPAN

  perl -MCPAN -e shell
  cpan> install Date::Parse
  cpan> install Date::Format
  cpan> install Data::Dumper
  cpan> install Compress::Zlib
  cpan> install MIME::Base64
  cpan> install Storable
  cpan> install Exception::Class
  cpan> install Class::MethodMaker
  cpan> install Hook::LexWrap
  cpan> install Aspect
  cpan> exit

If anyone finds other dependent modules, please let me know.

GET App SOFTWARE ^

Get App From CPAN

The App is not yet on CPAN. Try one of the other methods.

Get App from CVS (to develop App)

You should use this method if you *do* have commit access on the App CVS repository. (Note, substitute your CVS user id for "LOGIN" below.)

  cd $PREFIX/src
  cvs -d :pserver:LOGIN@cvs.perl.org:/cvs/public login
  [enter your perl.org password]
  cvs -d :pserver:LOGIN@cvs.perl.org:/cvs/public co p5ee

Later, when you want to refresh your directory with the latest software from CVS, you can repeat the same commands or you can do the following.

  cd $PREFIX/src/p5ee
  cvs update -dP

See a CVS document to find out how to create, delete, and modify files and then submit changes.

Get App from CVS (anonymous, read-only access to latest App)

You should use this method if you do *not* have commit access on the App CVS repository but you do want to stay up to date with the latest App software (recommended, because there are no releases yet).

  cd $PREFIX/src
  cvs -d :pserver:anonymous@cvs.perl.org:/cvs/public login
  [press enter at the password prompt]
  cvs -d :pserver:anonymous@cvs.perl.org:/cvs/public co p5ee

Later, when you want to refresh your directory with the latest software from CVS, you can repeat the same commands or you can do the following.

  cd $PREFIX/src/p5ee
  cvs update -dP

The "cvs update" method is the preferred way to get updates.

Get App from a Snapshot

If you do not have CVS on your system, you can still get reasonably recent sources from http://cvs.perl.org/snapshots/p5ee/.

  cd $PREFIX/src
  wget -O tar/p5ee-latest.tar.gz http://cvs.perl.org/snapshots/p5ee/p5ee-latest.tar.gz
  gunzip < tar/p5ee-latest.tar.gz | tar xvf -

If you don't have "wget" (http://www.gnu.org/software/wget/wget.html), you can use Perl's own LWP.

  cd $PREFIX/src
  perl -MLWP::Simple -e 'getstore("http://cvs.perl.org/snapshots/p5ee/p5ee-latest.tar.gz", "tar/p5ee-latest.tar.gz")'
  gunzip < tar/p5ee-latest.tar.gz | tar xvf -

INSTALL App SOFTWARE ^

Install Perl Modules, Man Pages, HTML Pages

  cd $PREFIX/src/p5ee/App
  make
  make test    (these may or may not work. the tests themselves are under development.)
  make install

Edit Main Config File

You will need to do this one time.

  cd $PREFIX/src/p5ee/App-/cgi-bin
  cp demo.conf p5ee.conf
  vi p5ee.conf
  # edit the following lines:
  #   * perlinc       = list of perl include paths
  #   * scriptDir     = absolute path for directory which the "p5x" script will be in
  #   * scriptUrlDir  = path from http://localhost to the scriptDir
  #   * htmlDir       = absolute path for the "htdocs" directory
  #   * htmlUrlDir    = path from http://localhost to the htmlDir
  #   * ttTemplateDir = apsolute path for the "templates" directory

Make HTML Pages Visible on the Webserver

Make CGI Programs Visible on the Webserver
