Apache installation

stamcose · December 4, 2011, 12:06pm

Unfortunately, the page

http://en.opensuse.org/Apache_Quickstart_HOWTO

has got lost in the WEB removal!

Having installed Apache with Yast for SUSE 11.4 the command

find / -name apache

results in


/etc/apparmor.d/apache2.d
/etc/apparmor.d/abstractions/apache2-common
/etc/apache2
/etc/sysconfig/SuSEfirewall2.d/services/apache2-ssl
/etc/sysconfig/SuSEfirewall2.d/services/apache2
/etc/sysconfig/apache2
/etc/init.d/apache2
/etc/logrotate.d/apache2
/usr/share/susehelp/meta/Manuals/Productivity/apache.en.desktop

/usr/lib/apache2-itk
/usr/lib/apache2/usr/sbin/apache2ctl
/var/cache/apache2
/var/log/apache2
/var/lib/apache2

According to
Apache HTTP Server Version 2.0 Documentation - Apache HTTP Server

the server is started with the command

appachectl

Executing the command

gunzip /usr/share/man/man8/apachectl2.8.gz

there appears an executable “/usr/sbin/apache2ctl” but


/usr/sbin/apache2ctl start
httpd2: Syntax error on line 188 of /etc/apache2/httpd.conf: Could not open configuration file /etc/apache2/sysconfig.d/include.conf: No such file or directory

With the YAST installation there is nowhere a “*.conf” file!!

Is the SUSE setup not anymore in order? There must be loads of people to have installed Apache in SUSE in the past! Please advice

Actually, I found the archived

Apache Quickstart HOWTO - openSUSE

Here one finds that one should not use

/usr/sbin/apache2ctl start

as is said in

Apache HTTP Server Version 2.0 Documentation - Apache HTTP Server

but instead

rcapache2 start

in fact


linux-7bll:/usr/sbin # ls *apache*
apache2ctl  rcapache2

One finds the for the SUSE setup useless nominal command “apache2ctl” together with the undocumented command “rcapache2” that is the one that has to be used! The Yast setup is not really clean!

Without the “Apache_Quickstart_HOWTO” that is not available in the current documentation one is quite lost!

Why do you say it is undocumented?
The opensuse reference in chapter 30.3 clearly states

To start, stop, or manipulate Apache on a running system, use the init
script /usr/sbin/rcapache2. For general information about init scripts,
refer to Section 17.2.2, “Init Scripts”.

Why not simply look at the official documentation “openSUSE Reference”
/usr/share/doc/manual/opensuse-manuals_en/manual/book.opensuse.reference.html
It is installed by default on your system, if you are using kde it is
also in the kde help center (for gnome I do not know if it is in yelp).

At the end it tells you also where to look for the correct link

30.9.4. Miscellaneous Sources

If you experience difficulties specific to Apache in openSUSE, take a
look at the openSUSE wiki at http://old-en.opensuse.org/Apache. The
history of Apache is provided at
About the Apache HTTP Server Project - The Apache HTTP Server Project. This page also explains why
the server is called Apache.

And the link http://old-en.opensuse.org/Apache works.

But

Apache - openSUSE

does not help for the next fundamental problem

The program “first.pl” is properly in the cgi directory


linux-7bll:/srv/www/htdocs # file /srv/www/cgi-bin/first.pl
/srv/www/cgi-bin/first.pl: a /usr/bin/perl script text

How should the “action” parameter of the “form” tag be set?

Assuming the directory to be predefined (like “/srv/www/htdocs” is) one would assume


<html>
<form name="input" action="first.pl" method="post">
Text: <input type="text" name="mytext" />
<input type="submit" value="Submit" />
</form> 
</html>

Or possibly everything explicit:


<html>
<form name="input" action="http://192.168.0.134/srv/cgi-bin/first.pl" method="post">
Text: <input type="text" name="mytext" />
<input type="submit" value="Submit" />
</form> 
</html>

or possibly:


<html>
<form name="input" action="http://192.168.0.134/first.pl" method="post">
Text: <input type="text" name="mytext" />
<input type="submit" value="Submit" />
</form> 
</html>

But in all cases: “The requested URL was not found on this server”!

Thankful for help ho to send the data to
" /srv/www/cgi-bin/first.pl"

Being myself no apache expert (esp. not for cgi scripts) I would say the
url you should use is
action=“cgi-bin/first.pl”
or if you want to use the absolute path
action=“http://192.168.0.134/cgi-bin/first.pl”

I would also say since in the second case you access your own machine as
if it is from outside you need to ensure that the firewall opens port 80
in the yast firewall.

I hope some expert can help better here.

That looks sensible. It sounds like you need to do some reading on how
to configure Apache for CGI scripts. You might start at:

http://httpd.apache.org/docs/2.2/howto/cgi.html

which should also be loaded on your machine, I think.

Actually, the syntax to start program “bash” residing in /srv/www/cgi-bin is


<form name="input" action="/cgi-bin/bash" method="post">
Text: <input type="text" name="mytext" />
<input type="submit" value="Submit" />
</form>

In the Apache of the SUSE distribution there must be a


ScriptAlias /cgi-bin/ /srv/www/cgi-bin/

see
HowTo: Configure a Linux Apache Web Server on Suse/openSUSE for SSI, Includes, CGI, Common Gateway Interface, AddHandler, ExecCGI, AllowOverride, htaccess, DocumentRoot

This is clearly a standard, the html code must run on all kinds of servers supporting CGI

True. That’s the simplest to set up.
