As the ASP is very easy to use, many companies choose ASP to develop their IT solution on Windows 2000 Server + ASP + MSSQL. However, this idea also have its disadvantages. And when your are going to transfer to linux, you will find big problems. There are two ways to transfer ASP to Linux.
1. Use PHP instead of ASP. Change from MSSQL to Mysql. It is more stable solution. However, this takes more time and cost more.
2. Run ASP on Linux. Connect to separate MSSQL. The difficulty is Linux don’t support ASP.
Now I’d like to tell you how to run ASP on Linux. I uses redhat Linux + Apache + iASP + ASP to connect to MSSQL server.
My Runtime environment:
OS: Redhat DC Server 5.0 for x86 SP3
Webserver: Apache 2.0
runtime: iASP 2.1.1
java: Sun jdk
Database: Windows 2000 Server + MSSQL 2000
Configure Java runtime
In consideration of compatibility, I uses Sun 1.4.2 JDK. You can download iASP from Sun.
1. Installation
Unpack:
# sh j2re-1_4_2_15-linux-i586-rpm.bin Unpacking... Checksumming... 0 0 Extracting... UnZipSFX 5.40 of 28 November 1998, by Info-ZIP (Zip-Bugs@lists.wku.edu). inflating: j2re-1_4_2_15-linux-i586.rpm
Install:
# rpm -ivh j2re-1_4_2_15-linux-i586.rpm
2. Configure
The redhat 1.5.0 has a java build in
# whereis java java: /usr/share/java # java -version java version "1.5.0_04" Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_04-b05) Java HotSpot(TM) Client VM (build 1.5.0_04-b05, mixed mode)
Change it to:
# ln -s /usr/java/j2re1.4.2_15 /usr/java/j2re1.4.2
Then edit /etc/profile.d/sun_java_sdk.sh:
#jdkroot=/usr/lib/jdk jdkroot=/usr/java/j2re1.4.2
Re-login to your server after saved it.Then check:
# su - root # java -version java version "1.4.2_15" Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_15-b02) Java HotSpot(TM) Client VM (build 1.4.2_15-b02, mixed mode)
Install iASP 2.1.1
You can download the iASP from here.
1. Unpack
# mkdir iASP_dir # tar xzvf iASP2.1.01.tar.gz -C iASP_dir/ iasp21.tar install.sh README
2. Install iASP
# cd iASP_dir/ # ./install.sh
Configure iASP with right java runtime path:
Please enter the full path to your JDK's bin directory. e.g. /usr/jdk1.1.6/bin, Q/q(quit), S/s(skip): /usr/java/j2re1.4.2/bin
Edit iASP installation path:
Enter the absolute directory under which Instant ASP should be installed. (./iasp21 will be created underneath.) > /usr/iasp Directory /usr/iasp does not exist, create it (Y/N/Q)? > y
※Do please not use “/” after the path.
Configure the Web server. Here I uses Apache 2.0:

Would you like to configure another web server (Y/N)?n
Configuration successful. You can access the Instant ASP documentation and samples from the virtual directory /iasp/
Result:
Server Information:iASP Path: /usr/iasp/iasp21 iASP Version: 2.1.01 OS Name: Linux 2.6.9-42.7AXsmp Host IP: 192.168.228.250 Java Path: /usr/java/j2re1.4.2_15 Java Version: 1.4.2_15 Java Vendor: Sun Microsystems Inc. iASP License: No License
3. Configure
You will find error if you start Apache now:
# service httpd start Start httpd：httpd: module "mod_iasp.c" is not compatible with this version of Apache (found 20020329, need 20020903). Please contact the vendor for the correct version. [Failed]
This is because the iASP module is encoded with 20020329 Apache. We need to configure a new module:
# cd /usr/iasp/iasp21/bin/apache/source/2.0/ # apxs -i -c *.c
The new module should be placed here:
/usr/lib/httpd/modules/mod_iasp.so
Edit “/etc/httpd/conf/httpd.conf”:
LoadModule iasp_module "/usr/lib/httpd/modules/mod_iasp.so"
Start Apache: # service httpd start
Start iasp proxy module:
# /usr/iasp/iasp21/start-server.sh & logging to stdout iASP/2.1.01 started [1] 13846
Listen port 9098:
# netstat -ln|grep 9098 tcp 0 0 :::9098 :::* LISTEN
Stop iASP:
# /usr/iasp/iasp21/stop-server.sh iASP server stopped
Test ASP on Linux
1. Create an ASP test file
You can create a test.asp under “/var/www/html/” folder. The following is an simple example:
<html> <head> <title>Test iASP</title> </head> <body> <% Response.Write "<BR><h1>Congradulations!<BR>Instant ASP has worked for you!</h1>" %> </body> </html>
2. Finished
ASP codes can run on Linux Apache if you see the following words:
Congratulations!
Instant ASP has worked for you!
Then you can edit configuration in httpd.conf to add virtual server, directory or index.asp. You can even run PHP and ASP on one server.
