Installing
DIAL (UNIX)
To install DIAL, copy the appropriate
distribution file (.Z or .gz) to your
local disk and follow the steps given
below:
- Use the UNIX command
'uncompress'
for decompressing
.Z
files, or use the UNIX command
'gunzip'
for decompressing
.gz
files.
- Use the
'tar
-xvf' for untarring the
decompressed
.tar
files.
- Move the contents of the cgi-bin,
htdocs and icons directories in the
distribution file to the corresponding
directories under the HTTP server root
directory. Also make sure that the HTTP server have the writing permission to the directory "/cgi-bin/dib/tmp" and "/htdocs/dib_home/gif".
Finally, if you are using an Apache
server, make the following changes in the
srm.conf file located under the
<Server Root>/conf
directory.
- Uncomment the ScriptAlias /cgi-bin/
which points to the /cgi-bin/ directory
under the server root directory.
- Set the Alias /HDF/ to point to the
/htdocs/hdf/ directory under the server
root directory. (e.g. Alias
/hdf/
"/usr/local/apache/htdocs/hdf/")
- Set the Alias /icons/ to point to
the /icons/ directory under the server
root directory.
For other
types of HTTP servers, please consult your
Web administrator for setting up the above
aliases.
Testing
your Installation
- Restart your Web server. (To
launch Apache web server, go to
START/Programs/Apache Web Server/
and click on the Apache
Server)
- Go to START/Programs/Dial/
and click on the My DIAL Home
Page or do the following two
steps.
- Bring up your favorite Web
browser.
- Enter the URL: "http://<your
machine internet name>/test.html"
or
"http://localhost/test.html"
NOTE:
If you are not running your Web server on
the standard port, i.e., port 80, then you
need to specify the port number in your
URL. (For example, if you are running your
Web server on port 8090, use the URL:
http://localhost:8090/test.html).
