You must have a apache web server with the php module activate. The php page must have the .phtml and .xsl extension. If your are not sure, verify your httpd.conf file it must contain the following command:

DirectoryIndex index.html index.phtml
AddType application/x-httpd-php3 .phtml
AddType application/x-httpd-php3 .xsl

Next you must create a new virtual domain (httpd.conf) like this:

<VirtualHost 192.168.1.10>
ServerAdmin webmaster@company.com
DocumentRoot /home/httpd/html/shop
ServerName shop.company.com
CustomLog /var/log/httpd/shop_log combined
<Directory /home/httpd/html/shop/include>
  deny from all
  AllowOverride None
</Directory>
</VirtualHost>

You must add to your php.ini file the following entry in include_path option:

include_path = "<old options>:.:./include"         

Your FTP daemon must accept anonymous login and accept upload in the 'pub/user/shop' directory, for that you must add the following option in the /etc/ftpaccess file:

upload /home/ftp /pub/user/* yes ftp daemon 0666 nodirs

Go in the /home/ftp/pub directory and change the security rights: chmod 711 user

Second step
Download istore.tgz (the source of the e-business web server) and istore-manager.zip (the win 95/98/NT software).
Uncompress istore.tgz (tar -xvzf istore.tgz), this will create a istore directory. Go to the istore directory and move the shop directory in /home/httpd/html.
Log as postgres and create a new postgreSQL database (createdb shop), then we start to populate this new database with the file shop.dmp (psql shop < shop.dmp). Verify that you launch the postgres daemon with the '-i' option (for better performance add the '-o-F' option) on my RedHat system this file is in '/etc/rc.d/init.d' directory. Modify the /home/httpd/html/shop/config.php file to fit your needs.

Third step
As root create the directory /usr/local/xslpserver. In this new directory put the openxml.jar, xslp.jar, XSLPServer.class, XSLPServerThread.class, and the xslpserver file (the .class and xslpserver files come from the istore.tgz package). If your JDK is not in /usr/local/jdk1.1.7B you must change the xslpserver script according to your system configuration. Now run xslpserver.
Move the integ.sh script in /home/ftp/pub/user, go to /home/ftp/pub/user then create the 'shop' and 'tmp' directory change their security rights chmod 777 tmp and chmod 777 shop. Now in the /home/ftp/pub/user/shop directory put the 'DB' and 'importe' file ('importe' must have the execute bit set: chmod 755 importe).
Run the integ.sh script.
All the install process on the web server is finish and you can test now your Internet shop.
