The latest version of SASSLO source code is 2.8 !


Download Source Code Package
Download the SASSLO V2.8 Source Code from here (zip file)

After downloading the source code package, you have to follow the installation guide to complete the installation of the system. There are different settings in different operation system.

Installation for Windows
  • Step 1
    		•  Install your web server and PHP(MUST be PHP version 4.x) on your system, and make sure that it works. The PHP version must be 4.X due to the different XML library between 4.X and 5.X.
    You are recommended to use the AppServ installation package (you are not required to install MySQL server when you are asked to select the components during the installation of AppServ).

  • Step 2
    		•  Install Java 2 Runtime Environment(J2RE) onto your system. You can download the Java 2 Runtime Environment(J2RE) package from the Sun's Java website.

  • Step 3
    		•  If you are not using the AppServ installation package, extract the PHP library file called "php_domxml.dll" from the source code zip file to the extensions directory of your PHP (e.g. C:\PHP\extensions).

  • Step 4
    		•  Find "php.ini" in the Windows directory of your computer (for example c:\windows) and open it with notepad. Search for the words "Windows Extensions". Uncomment the line "extension=php_domxml.dll". Make sure the setting "allow_call_time_pass_reference" is "On" (usually, the default setting is On). Then save the file. Restart your web server.

  • Step 5
    		•  Extract the distribution files from the source code zip file to the document root directory of your web server or any sub-directory of the document root directory.
    (e.g. for apache 1.3.x C:\Program Files\Apache Group\Apache\htdocs\<sub-directory>
             for apache 2.0.x C:\Program Files\Apache Group\Apache2\htdocs\<sub-directory>
             for AppServ C:\AppServ\www\<sub-directory>
    )
  • Step 6
    		•  After the extraction you can see a directory called "Search" under the document root directory. Open the iniParam.php file in the search directory using any text editor, as shown in Figure 1.

    Figure 1. iniParam.php

    You need to set the following four constants:

    BASE_PATH: the path to the search directory (main directory of the spider program).
    (e.g. for apache 1.3.x "C:/Program Files/Apache Group/Apache/htdocs/<sub-directory>/Search/"
             for apache 2.0.x "C:/Program Files/Apache Group/Apache2/htdocs/<sub-directory>/Search/"
             for AppServ "C:/AppServ/www/<sub-directory>/Search/"
    )

    BASE_WEBPAGE_PATH: the base path of the web page link to spider application.
    (e.g. "http://<your hostname>/<sub-directory>/Search/")

    ADMIN_USER_NAME: administrator username.
    (e.g. "<username>")

    ADMIN_PWD: administrator password.
    (e.g. "<password>")
  • Step 7
    		•  After the configuration of iniParam.php file the installation is completed. You can get started from "http://<your hostname>/<sub-directory>/Search/".

    Please ensure the files in the search\admin\database directory are writable.




    Installation for Unix/Linux
  • Step 1
    		•  Install your web server and PHP(MUST be PHP version 4.x) on your system, and make sure that it works. The PHP version must be 4.X due to the different XML library between 4.X and 5.X.
    You are recommended to use the Xampp installation package which already includes web server and PHP.

  • Step 2
    		•  Install Java 2 Runtime Environment(J2RE) onto your system. You can download the Java 2 Runtime Environment(J2RE) package from the Sun's Java website.

  • Step 3
    		•  Find "php.ini" in the appropriate directory of your computer (for example /opt/lampp/etc/php.ini) and open it with any text editor. Make sure the setting "allow_call_time_pass_reference" is "On" (usually, the default setting is On). Then save the file. Restart your web server.

  • Step 4
    		•  If you are using Xampp package, you should execute this command "/opt/lampp/lampp php4" in order to switch back to PHP 4.x.

  • Step 5
    		•  Extract the distribution files from the source code zip file to the document root directory of your web server or any sub-directory of the document root directory.
    (e.g. for Xampp: /opt/lampp/htdocs/<sub-directory>)
  • Step 6
    		•  After the extraction you can see a directory called "Search" under the document root directory. You need to type the following two commands so that the SASSLO system work properly.
    • chown -R nobody ./Search/
    • chmod -R 700 ./Search/
  • Step 7
    		•  Open the iniParam.php file in the "Search" directory using any text editor, as shown in Figure 1.

    Figure 1. iniParam.php

    You need to set the following four constants:

    BASE_PATH: the path to the search directory (main directory of the spider program).
    (e.g. for Xampp: "/opt/lampp/htdocs/<sub-directory>/Search/")

    BASE_WEBPAGE_PATH: the base path of the web page link to spider application.
    (e.g. "http://<your hostname>/<sub-directory>/Search/")

    ADMIN_USER_NAME: administrator username.
    (e.g. "<username>")

    ADMIN_PWD: administrator password.
    (e.g. "<password>")
  • Step 7
    		•  After the configuration of iniParam.php file the installation is completed. You can get started from "http://<your hostname>/<sub-directory>/Search/".
