Installing queXF in Ubuntu

queFX is a web based Intelligent Character Recognition(ICR) software. queFX can be used as a Computer Assisted Data Entry(CADE) tool. It is written in PHP and uses MySQL as backend. In this document I am going to install queXF in an Ubuntu 12.04 box. We will need Apache, PHP, MySQL, ADOdb and Ghostscript.

Install Apache

# apt-get install apache2

Install MySQL

# apt-get install mysql-server

Install PHP5 and required extensions

# apt-get install php5 php5-gd php5-mysql

Install Ghostscript

# apt-get install ghostscript

Download and extract ADOdb from http://sourceforge.net/projects/adodb/files/adodb-php5-only/adodb-518-for-php5/

# unzip adodb518a.zip

Copy the extracted directory into some location

# cp -r adodb5 /usr/local/

 

Change post_max_size to 10MB, upload_max_filesize to 10MB and memory_limit to 128MB in PHP configuration file

# pico /etc/php5/apache2/php.ini

Download queXF from http://sourceforge.net/projects/quexf/files/quexf/quexf-1.13.5/

Extract the zip file

# unzip quexf-1.13.5.zip

Copy the extracted files into Apache’s document root directory

# cd quexf-1.13.5/

# cp -rf * /var/www/

Change the owner of the files from current user

# chown -R www-data:www-data *

 

We need to enable user authentication in Apache.

Create a password file for Apache and store this file is in some safe location (somewhere not accessible from the web).

# mkdir -p  /usr/local/apache/passwd

# htpasswd -c /usr/local/apache/passwd/passwords pranabs

image

Add more user using the same command but without –c option, otherwise it will overwrite the file and previously created users:

# htpasswd /usr/local/apache/passwd/passwords ajitj

 

My apache config file for default site looks like

# cat /etc/apache2/sites-available/default


<VirtualHost *:80>
        ServerAdmin webmaster@localhost

        DocumentRoot /var/www
        <Directory />
                Options FollowSymLinks
        </Directory>
        <Directory /var/www/>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride All
                Order allow,deny
                Allow from all
        </Directory>

        ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
        <Directory "/usr/lib/cgi-bin">
                AllowOverride None
                Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
                Order allow,deny
                Allow from all
        </Directory>

        ErrorLog ${APACHE_LOG_DIR}/error.log

        # Possible values include: debug, info, notice, warn, error, crit,
        # alert, emerg.
        LogLevel warn

        CustomLog ${APACHE_LOG_DIR}/access.log combined

    Alias /doc/ "/usr/share/doc/"
    <Directory "/usr/share/doc/">
        Options Indexes MultiViews FollowSymLinks
        AllowOverride None
        Order deny,allow
        Deny from all
        Allow from 127.0.0.0/255.0.0.0 ::1/128
    </Directory>

</VirtualHost>

 

Create .htaccess file in the queFX root directory

#pico /var/www/.htaccess

and add the following content:

AuthType Basic
AuthName "Restricted Files"
AuthUserFile /usr/local/apache/passwd/passwords
Require valid-user

 

Restart Apache

# service apache2 restart

 

Create MySQL database and user

mysql> create database quexf;
Query OK, 1 row affected (0.00 sec)

mysql> grant all privileges on quexf.* to 'quexf'@'localhost' identified by 'quexf';
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)


Import the quexf database script provided inside the database folder inside quexf application directory.

# mysql -u quexf -pquexf quexf < /var/www/database/quexf.sql

 

Change the queXF configuration file, set the database connection details and path for ADOdb and Ghostscript

# pico /var/www/config.inc.php

image

 

To test the configuration, open the link (http://servername/admin/?page=testconfig.php)

Example:

http://192.168.10.179/admin/?page=testconfig.php

You will be asked for username and password.

Enter user login that we created with htpasswd command. If configuration is fine, we will see the Passed Configuration Test message:

That’s it, our queXF installation is ready Smile .

I am live in Cambodia
I want to change htaccess but i don't know to change it.

.htaccess is a hidden file. So you will not see it using normal ls command. You can use any text editor to change the file, if .htaccess does not exists, then you can create it.
