==Installing required packages==
Moved to manual - https://wiki.apertus.org/index.php/AXIOM_Beta/Manual#Installations
 
Make sure the AXIOM Beta is connected to the internet and then on the commandline run:
 
Update system:
pacman -Syu
 
Install webserver:
pacman -S lighttpd php php-cgi
 
start the webservice:
systemctl start lighttpd
 
write any pending changes to the file system:
sync
 
==Configure Webserver==
 
This is following the guide from the lighttpd archlinux wiki page: https://wiki.archlinux.org/index.php/lighttpd
 
mkdir /etc/lighttpd/conf.d/
nano /etc/lighttpd/conf.d/cgi.conf
 
and place the following content in the file:
<nowiki>server.modules += ( "mod_cgi" )
 
cgi.assign                = ( ".pl"  => "/usr/bin/perl",
                              ".cgi" => "/usr/bin/perl",
                              ".rb"  => "/usr/bin/ruby",
                              ".erb" => "/usr/bin/eruby",
                              ".py"  => "/usr/bin/python",
                              ".php" => "/usr/bin/php-cgi" )
 
index-file.names          += ( "index.pl",  "default.pl",
                              "index.rb",  "default.rb",
                              "index.erb",  "default.erb",
                              "index.py",  "default.py",
                              "index.php",  "default.php" )</nowiki>
 
For PHP scripts you will need to make sure the following is set in /etc/php/php.ini
 
cgi.fix_pathinfo = 1
 
In your Lighttpd configuration file, /etc/lighttpd/lighttpd.conf add:
 
include "conf.d/cgi.conf"
 
Create a new configuration file /etc/lighttpd/conf.d/fastcgi.conf
 
<nowiki># Make sure to install php and php-cgi. See:                                                           
# https://wiki.archlinux.org/index.php/Fastcgi_and_lighttpd#PHP
 
server.modules += ("mod_fastcgi")
 
# FCGI server
# ===========
#
# Configure a FastCGI server which handles PHP requests.
#
index-file.names += ("index.php")
fastcgi.server = (
    # Load-balance requests for this path...
    ".php" => (
        # ... among the following FastCGI servers. The string naming each
        # server is just a label used in the logs to identify the server.
        "localhost" => (
            "bin-path" => "/usr/bin/php-cgi",
            "socket" => "/tmp/php-fastcgi.sock",
            # breaks SCRIPT_FILENAME in a way that PHP can extract PATH_INFO
            # from it
            "broken-scriptfilename" => "enable",
            # Launch (max-procs + (max-procs * PHP_FCGI_CHILDREN)) procs, where
            # max-procs are "watchers" and the rest are "workers". See:
            # https://redmine.lighttpd.net/projects/1/wiki/frequentlyaskedquestions#How-many-php-CGI-processes-will-lighttpd-spawn
            "max-procs" => 4, # default value
            "bin-environment" => (
                "PHP_FCGI_CHILDREN" => "1" # default value
            )
        )
    ) 
)</nowiki>
 
Make lighttpd use the new configuration file /etc/lighttpd/lighttpd.conf
 
include "conf.d/fastcgi.conf"
 
 
restart lighttpd:
systemctl restart lighttpd
 
To test php create a file: /srv/http/index.php with content:
<nowiki><?php
phpinfo();
?></nowiki>
 
and open this IP address of your AXIOM Beta in a browser, if you see the php info status page everything worked successfully.
 
==Install AXIOM Beta web GUI software==
 
Download this repository:
https://github.com/apertus-open-source-cinema/beta-software
 
#copy all files from the http directory of the repository to your AXIOM Beta /srv/http/ directory.
#copy all files from the beta-scripts directory of the repository to your AXIOM Beta /root/ directory.
 
Edit /etc/sudoers files:
 
under the line:
root ALL=(ALL) ALL
 
add:
http ALL=(ALL) NOPASSWD: ALL
 
This allows the http user to do anything with the system so it can be considered a security vulnerability - but for development this should not be an issue, later on we will define the http priviledges more securely.
 
For testing sudoers:
sudo -u http sudo whoami
if it returns "root" then you are all set
 
This should provide you with a working webbased GUI.
 
Note that lighttpd does not start automatically when the AXIOM Beta boots, this still needs to be configured:
systemctl enable lighttpd
 
Also note that opening any websites that read image sensor registers before initializing the image sensor (kick_manual.sh) will freeze/crash the camera.
