To run the script:
$ addsite
ipaddress
port
name
root
If you get the message command not found when you try to run the script, precede the
command with the full path to the script file. For example:
/users/admin/documents/addsite 10.0.0.2 80 corpsite /users/webmaster/sites/
corpsite
Or, use cd to change to the folder that contains the file and precede the command with
./. For example:
$ cd /users/admin/documents
$ ./addsite 10.0.0.2 80 corpsite /users/webmaster/sites/corpsite
Tuning the Server Performance
When trying to analyze the server’s performance, keep in mind that a lot of factors can
affect performance: CGI scripts growing too large, database queries exhausting your
computer’s resources, too much network traffic, and so on.
Apache provides a basic benchmarking tool, ab. You can use ab to simulate hits to your
web server and thus get an idea of how long it takes your website to respond, as well
as other valuable statistics. The following command will simulate 1000 requests to the
specified URL with the user name and password provided.
$ ab -n 1000 -c 1 -A
user
:
password
www.
student number
