NAME

Catalyst::Manual::Installation::CentOS4 - Catalyst Installation on CentOS 4

DESCRIPTION

This document provides directions on how to install CentOS 4 (a rebuild of RedHat Enterprise 4) and then install Catalyst.

If you already have a functioning install of CentOS, RHEL, or a comparable Linux OS, you should be able to skip this first section and go straight to the "INSTALL CATALYST" section.

NOTE: You might want to consult the latest version of this document. It is available at: <http://dev.catalyst.perl.org/repos/Catalyst/trunk/Catalyst-Runtime/lib/Catalyst/Manual/Installation/CentOS4.pod>

INSTALL CENTOS

These directions are written for CentOS 4.4 on an i386 machine; however, you can substitute other versions as they become available.

•

Go to <http://isoredirect.centos.org/centos/4/isos/i386/> and click the nearest mirror.

•

Download "CentOS-4.4-i386-bin1of4.iso" (you only need the first disk).

•

Burn the .iso to CD.

•

Insert the CD into your machine and power it up.

•

Hit "Enter" at the "boot:" prompt.

•

CD media test: you can either select "OK" or "Skip" depending on whether or not you trust your burn.

•

The installation GUI should start. Click next at the ``Welcome to CentOS-4'' screen.

•

Select a language and click "Next".

•

Select a keyboard configuration and click "Next".

•

Select "Custom" for the installation type and click "Next".

•

Leave "Automatically partition" selected on the "Disk Partitioning Setup" and click "Next".

•

Uncheck "Review (and modify if needed) the partitions created", but leave the rest of the default settings on the "Automatic Partitioning" screen. Then click "Next".

•

Click "Yes" at the "Are you sure you want to do this?" warning.

•

Click "Next" on the "Boot Loader Configuration" screen.

•

Update the "Network Configuration" screen as necessary and click "Next".

•

Check "Remote Login (SSH)" and click "Next" on the "Firewall Configuration" screen.

•

Select additional languages as necessary. Click "Next".

•

Select the appropriate time zone and click "Next".

•

Enter a root password and click "Next".

•

Scroll to the bottom of the "Package Group Selection" screen and check "Minimal" (the last option). Click "Next".

•

Click "Next" at the "About to Install" screen.

•

The installation will prepare the hard drive and then install the required rpm packages.

•

Once the installation completes, remove the CD and click "Reboot".

•

Type "vi /etc/sysconfig/iptables" and add the following line as the third to last line of the file (above the "-A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited" line):

     -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 3000 -j ACCEPT
 
 

This will allow Catalyst to make use of port 3000 (the default for the development server).

Type "service iptables restart" to restart the iptables firewall using the updated configuration.

•

Type "yum -y update" to retrieve the latest patches.

INSTALL CATALYST

•

Type "yum -y install gcc expat-devel sqlite3" to install several packages used by Catalyst.

•

Type the following:

     $ perl -MCPAN -e shell
     
     ...
     
     Are you ready for manual configuration? [yes] yes
     The following questions are intended to help you with the
     
     ...
     
     cpan shell -- CPAN exploration and modules installation (v1.7601)
     ReadLine support available (try 'install Bundle::CPAN')
         
     cpan> force install Module::Build
     
     ...
     
     cpan> quit
 
 

•

Note: You need to have CPAN manually configured prior to running cat-install. As shown above, you should automatically receive a prompt for this when you first run "perl -MCPAN -e shell". You can re-run the configuration script by typing "o conf init" at the "cpan>" prompt.

Optional: The remaining steps of the installation could run significantly faster if you configure a fast mirror that uses HTTP vs. FTP (both transfer data at the same rate once the transfer is in progress, but HTTP connects much more quickly... and a Catalyst installation involves many connections). If you want to change the selection(s) you made during the ``manual configuration'' process above, you can manually add a single URL. To prepend a new URL to the front of the list, use the "unshift" option to "o conf":

     cpan> o conf urllist unshift http://www.perl.com/CPAN/
 
 

Where "http://www.perl.com/CPAN/" is replaced by a nearby, HTTP-based mirror. You can get a list of all mirrors (including where they are located, their bandwidth, and their update frequency) at <http://www.perl.com/CPAN/MIRRORED.BY>.

Then, be sure to save your changes (or they will be lost the next time you restart the CPAN shell):

     cpan> o conf commit
 
 

You can view the current settings with "o conf urllist" (or just "o conf" to view all settings):

     cpan> o conf urllist
         urllist           
             http://www.perl.com/CPAN/
     Type 'o conf' to view configuration edit options
 
 

Note that multiple values can be entered for the "urllist" option (the first entry will be used as long as it responds).

Review the "cat-install" documentation from the <http://www.shadowcatsystems.co.uk> web site:

     If you want to get started quickly with Catalyst, Shadowcat provides an 
     installer script that will automate most of the process of installing it 
     for you. Please bear in mind that this script is currently considered 
     beta quality; we don't think it will eat your system but we make no 
     guarantee of that.
     
     First, you'll need -
     
         * Perl, 5.8.1+ (if you're on windows, get it from Active State)
         * make of some sort. On unix/linux you should already have one. On 
             windows get nmake from Microsoft.
         * A compiler. On unix/linux you should already have one. On windows, 
             get the latest Dev-C++ beta.
         * All three of the above in your PATH for whatever shell you're using
         * A configured CPAN.pm. perl -MCPAN -e shell should get CPAN to walk 
             you through the configuration process
         * Module::Build. Active State kindly include this for you.
     
     Ok, now that your environment is set up, download the installer from 
     this link, open a command prompt in the directory you downloaded it to 
     and run perl cat-install. By the time it exits, you should have a full 
     Catalyst install.
     
     If anything goes wrong, please send the full build log and the output of 
     perl -V to cat-install (at) shadowcatsystems.co.uk so we can try and 
     resolve your issue.
 
 

•

Type "wget http://www.shadowcatsystems.co.uk/static/cat-install" to retrieve a copy of the "cat-install" script.

•

Type "vi cat-install" to open the installer script, then insert the following lines at the bottom of the file (after the "install('Catalyst');" line):

     install('ExtUtils::ParseXS');
     install('Digest::SHA1');
     install('Digest::SHA');
     install('DBIx::Class');
     install('DBIx::Class::HTMLWidget');
     install('Module::ScanDeps');
     install('Module::CoreList');
     install('PAR::Dist');
     install('Archive::Tar');
     install('Module::Install');
     install('Catalyst::Devel');
     install('Catalyst::Plugin::ConfigLoader');
     install('Catalyst::Plugin::Session');
     install('Catalyst::Plugin::Session::State::Cookie');
     install('Catalyst::Plugin::Session::Store::FastMmap');
     install('Catalyst::Plugin::Authorization::ACL');
     install('Catalyst::Plugin::Authentication');
     install('Catalyst::Plugin::Authorization::Roles');
     install('Catalyst::Plugin::Authentication::Store::DBIC');
     install('Catalyst::Plugin::DefaultEnd');
     install('Catalyst::Plugin::StackTrace');
     install('Catalyst::Plugin::Dumper');
     install('Catalyst::Plugin::HTML::Widget');
     install('Catalyst::Model::DBIC::Schema');
     install('Catalyst::View::TT');
     install('Test::WWW::Mechanize');
     install('Test::WWW::Mechanize::Catalyst');
     install('Test::Pod');
     install('Test::Pod::Coverage');
 
 

•

Type "perl cat-install". It will take a while to complete.

Tip: You may want to enable logging of the output that "cat-install" generates as it runs --- it can be useful if you need to troubleshoot a failure. The log will generate almost 1 MB of output.

Note: Once the "perl cat-install" is complete, you may want to rerun the command to check the status of the packages listed in <cat-install>. Ideally, everything should return a name "is up to date" message. If any packages try to re-install, the you could need to manually install the package with the "force" option. Also, look for new optional dependences that "cat-install" was not able to automatically handle. You can address these by manually installing the dependency and then re-running "perl cat-install".

In some cases you may wish to install an earlier version of a module. For example, say that the latest version of Module::Install is 0.64 and you want to install 0.63. The following command under "perl -MCPAN -e shell":

     cpan> install A/AD/ADAMK/Module-Install-0.63.tar.gz
 
 

You should now have a functioning Catalyst installation with the modules and plugins required to run the Catalyst tutorial.

TESTING THE INSTALLATION

•

Download the tarball of the final tutorial application:

     $ wget http://dev.catalyst.perl.org/repos/Catalyst/trunk/examples/Tutorial/Final_Tarball/MyApp.tgz
 
 

•

Untar it:

     $ tar zxvf MyApp.tgz
     $ cd MyApp
 
 

•

Run the tests:

     $ CATALYST_DEBUG=0 prove --lib lib  t
     t/02pod...............skipped
             all skipped: set TEST_POD to enable this test
     t/03podcoverage.......skipped
             all skipped: set TEST_POD to enable this test
     t/01app...............ok
