Mason

Mason compiles the components and caches out the results for better  
performance see http://www.masonhq.com/?FAQ:Caching. The directory '/ 
usr/local/www/mason/obj' is where Mason is trying to put the compiled  
objects on your system. However, the directory /usr/local exists but / 
usr/local/www does not. Mason attempts to create the directory  
structure for you but the permissions on /usr/local are preventing  
this from happening. To see the permissions on /usr/local type "ls - 
ld /usr/local" at a command prompt. There are a couple of ways to fix  
this problem:
	1) Create the directory structure and apply the correct permissions.
	2) Change where mason is writing the object files
	3) Stop using object files

Option 1 will probably be the easiest for you. To do this open a  
command prompt and type:
	mkdir /usr/local/www
	chown -R <apache user>:<apache group> /usr/local/www
<apache user> and <apache group> is the user/group that you are  
running apache as. I don't have Ubuntu at my disposal right now so I  
can't say which user it uses by default but you can check the apache  
configs for a User and Group declaration or, if you can't find it, you  
can try to use the ps command. "ps -ef | grep http". If you get any  
errors your user may not have permission to write to /usr/local and  
you either need to switch to root or try using sudo to run the  
commands. Once you have the user and make and chown the www directory  
Mason should be able to set up its object directories without even  
restarting the apache server.

I don't recommend option 3 but if you wanted to try that or option 2  
take a look as the Mason admin docs http://www.masonhq.com/docs/manual/Admin.html#performance 
.

Hope this helps.

Just to add that on Ubuntu this should be set to www-data in both places 
and you'll probably need to prefix each command with sudo to get the 
right permissions to do it

regards,

Paul

please someone kindly give detail instructions on how to do it
Pls!!!

Hi Saad,

John's post seems very clear already...can you be more specific with your request?  What part of 
what he said did you not understand?  How far did you get with his instructions?

You may also want to tell us what you've tried already (the part in httpd.conf/apache2.conf that 
you've edited; what you have confirmed is working -- does the web server work?).

Ray

PS:  Take a look at the man pages of the commands that were suggested to you -- chown, chgrp, etc. 
if you don't know what they do.

After running the chown command for ubuntu (/var/www/) and making a
var/state/mason/ directory and giving it write access i got the following
error when trying to access mason-example directory from webserver this
mason example package is an additive to ubuntu mason package and
automatically gets installed in /var/www/mason-example/ folder  running this
in apache gives the following error

[Fri Feb 12 12:25:34 2010] [error] [client 127.0.0.1] Attempt to serve

Excerpts from Saad Murtaza khan's message of Fri Feb 12 03:47:36 -0500 2010:
> hello please reply anybody

I don't know about other people on this list, but sending this kind of message
makes me want to ignore you.  We aren't here breathlessly waiting to help you
and you aren't paying us anything.  Just wait until the people who have the
ability and desire to help you have the time to do so.

(I'd help, but I haven't set up mason in the manner you want for years.)

hdp.

Well... this kind of "behaving" is normal, since i past the same way "more
or less" and it's really hard to find good documentation... if any!

What i sugest is :

sudo chmod 777 -r /path/directory

Practice with mason... do your html... for your type of question you aren't
doing this for production but for learning (am i right?) so forget a little
bit about security... but keep in mind this isn't the best aproach, cos you
are "open the doors to the world" to write, delete , read your files.

If you need to configure your apache2 (i use apache2-threaded-dev cos i had
some complications with only the apache2)

my httpd.conf is :

<VirtualHost *:80>
ServerAdmin your@...
ServerAlias serveralias #host porpose
DocumentRoot /var/www/[yourapp]/docs
PerlSetVar  MasonCompRoot  /var/www/[yourapp]/
PerlSetVar  MasonDataDir   /var/www/[yourapp]/

 <LocationMatch "\.html|mc$">
    SetHandler   perl-script
    PerlHandler  HTML::Mason::ApacheHandler
 </LocationMatch>
</VirtualHost>


Hope this help you!

BTW : next if you want do :

sudo gedit /etc/hosts

and the ServerAlias you had choose put it in the 127.0.0.1 line and restart
apache2 ( sudo service apache2 restart)

Good Luck
