Requirements
------------
The system was tested with:
* postgresql 7.4+ / 8.2+
* apache 2.2+
* php 5.3+ (and some extensions)
Installation
------------
Before following the steps, you must be sure of:
* your php are integrated with your web server,
* the php extension module for the postgresql (php_pgsql.so or
php_pgsql.dll) is installed and configured,
* the postgresql database management system is running.
Usually that is true if you have installed the following
ubuntu/debian packages:
postgresql, postgresql-contrib, postgresql-client, apache2,
libapache2-mod-php5, php5, php5-cli, php5-cgi, php5-gd,
php5-mcrypt, php5-pgsql
It may be needed to configure some parameters in php.ini,
postgresql.conf and pg_hba.conf files. The following lines
show some important attributes for BOCA:
********* apache boca config file (to be included in /etc/apache2/conf.d/): **********
<Directory /var/www/boca>
AllowOverride Options AuthConfig Limit
Order Allow,Deny
Allow from all
AddDefaultCharset utf-8
</Directory>
<Directory /var/www/boca/private>
AllowOverride Options AuthConfig Limit
Deny from all
</Directory>
<Directory /var/www/boca/doc>
AllowOverride Options AuthConfig Limit
Deny from all
</Directory>
<Directory /var/www/boca/tools>
AllowOverride Options AuthConfig Limit
Deny from all
</Directory>
********* postgresql.conf: *********
tcpip_socket = true #if using tcp to connect to database (older postgresql's)
listen_addresses = '*' #newer postgresql's
# THE FOLLOWING MAY BE GOOD FOR PERFORMANCE
max_connections = 100
maintenance_work_mem = 64MB
shared_buffers = 32MB
work_mem = 3MB
********* pg_hba.conf: *********
#this is the access control file
#restricting connections from unixsocket or localhost is
#the best choice, but it could not enough if the
#database is not in the same machine.
host all all 127.0.0.1 255.255.255.255 md5
host all all 0.0.0.0 0.0.0.0 md5
# this last line will allow connection from everywhere. If you
# know the IP address of the machines that will serve as autojudging,
# then you may restrict the access to only such machine. Anyway,
# if you have a good password, that should not be a problem.
Steps for installing boca:
1) Unpack the boca file into a internet world readable directory,
e.g.:
> mkdir -p /var/www/boca
> cd /var/www/boca
> tar xvzf boca-x.y.z.tar.gz
2) create a postgresql account with permission to create new
databases (you need database admin privilegies to do that),
e.g.:
> psql -h 127.0.0.1 -U postgres -d template1
template1=# create user bocauser with password 'boca' createdb;
template1=# \q
3) edit the file private/conf.php (placed where you unpacked boca),
setting up the correct values. Ex:
$conf["dblocal"]="true"; // use unix socket to connect?
$conf["dbhost"]="localhost"; // ip address of the db
$conf["dbname"]="bocadb"; // name of the boca database
// it should be any name
$conf["dbuser"]="bocauser"; // unpriviligied boca user
$conf["dbpass"]="boca"; // unpriviligied boca password
$conf["dbsuperuser"]="bocauser"; // priviligied boca user
$conf["dbsuperpass"]="boca"; // priviligied boca password
// note that it is just fine to use the same user for
// unpriv and priv access, but you can separate them
// for increasing local security
// secret key to be used in HTTP headers
// you MUST set it with any random large enough sequence
// DONT LEAVE IT AS YOU GOT WHEN UNPACKED THE SOFTWARE
// CHOOSE ANOTHER NUMBER/STRING AND REPLACE BELOW
$conf["key"]="secretKey:23894091237589234759234723489";
// the following field is used by the autojudging script
// set it with IP address (or other short description)
// of the computer allocated for
// autojudging during the competition
$conf["ip"]='10.10.10.10';
4) run the php script to initialize the boca database
> cd /var/www/boca/
> php private/createdb.php
5) It's all done. Now you have to manage the contest with a
browser and boca. Proceed to the ADMIN.TXT file.
Security Issues
---------------
It is strongly recommended that BOCA be installed on a computer
with no other users. If the computer where you are installing BOCA
is used by others (with command line shells), it is essential
that you change the permission of the file private/conf.php to be
readable just by the user which the apache server runs and set
safe_mode=On in the php.ini file (furthermore, the database access
must be strictly restricted by passwords). Do it before configuring the
private/conf.php file, so no one will be able to see your passwords.
Moreover, the private/conf.php file must be in a directory owned by the
bocauser or www-data or apache (all this combination implies that the only
way to read the private/conf.php is from a php script owned by bocauser in
the same directory).
