Installing a webserver on AXIOM Beta
1 Installing required packages
Make sure the AXIOM Beta is connected to the internet and then on the commandline run:
pacman -S lighttpd php php-cgi
start the webservice:
systemctl start lighttpd
write any pending changes to the file system:
2 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:
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" )
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:
Create a new configuration file /etc/lighttpd/conf.d/fastcgi.conf
# 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 ) ) ) )
Make lighttpd use the new configuration file /etc/lighttpd/lighttpd.conf
systemctl restart lighttpd
To test php create a file: /srv/http/index.php with content:
<?php phpinfo(); ?>
and open this IP address of your AXIOM Beta in a browser, if you see the php info status page everything worked successfully.
3 Install AXIOM Beta web GUI software
Download this repository:
- 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
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.
