How to check that mod_deflate is enable ?

am 02.02.2010 10:46:28 von joydeep

Hello list,

I have suse 11.1 server with Apache/2.2.10 (Linux/SUSE). I like to
enable and check the presence of mod_deflate to save bandwidth.

"a2enmod -l " reports

`````````````````
actions alias auth_basic authn_file authz_host authz_groupfile
authz_default authz_user authn_dbm autoindex dir env expires include
log_config mime negotiation setenvif ssl suexec userdir php5 rewrite
unique_id security2 headers cgi

`````````````````

so tye module is not loaded, I have checked through yast also but no
such module present in the repository. How can I then enable and check
the presence of that module ? Please suggest.

Thanks

Check it's been included:

rpm -ql apache2 | grep deflate

Enable it:

a2enmod deflate

Hello Marty,

many many thanks for your kind attention and solution. It helped me.
Is there any way to check the deflate is operational ?

thanks once again.

Check in your main httpd.conf file for mod_deflate, and see if load is next to
it.

Thanks,

Daniel

Also trying reading the mod_deflate documentation:-

http://httpd.apache.org/docs/2.2/mod/mod_deflate.html

There you will see examples of how to configure a mod_deflate log file
which is useful is you want to see what mod_deflate is doing.

A couple of things that tripped me up whilst configuring this recently:-

1. mod_deflate doesn't seem to play nicely with IE6. Google
'mod_deflate IE6' to see what I mean. We ended up disabling it for
IE6.

2. If you configure mod_deflate logging in the main host, but you've
enabled virtual hosting, your log file will be created but it will be
empty. You need to configure the log file inside your Virtual Host
block instead.

Cheers,
Phil.

Thanks to all responders. I ensure that mod_deflate is now enable in my
suse 11.0 server

/etc/sysconfig/apache2
---------------------------------

[.....]

LoadModule deflate_module /usr/lib64/apache2-prefork/mod_deflate.so

[......]

I have placed the following in httpd.conf

[.......]

AddOutputFilterByType DEFLATE text/html text/plain text/xml

[.......]

and restarted apache. No error or complaining. But I have not found any
difference in access.log to see the presence of deflate. I admit I have
not change the LogFormat as awstats is running here and the LogFormat is
modified to support awstats. vhost logging is separated by vlogger here.

So I can see one of two options

1. mod_deflate is running but can't see here in log
2. mod_deflate is not running at all.

How can I go further to check it ?

thanks

Start by removing the IfModule directives.

Hello Frank,

I have already done that. To be in a safe side I have inserted the
config directly at a particular vhost like

[.....]
AddOutputFilterByType DEFLATE text/html text/plain text/xml
[.....]

This experiment does not affect other sites running here and log
analysis is easy also. After restarting the apache I have visited some
of the pages from that side but no more difference in the log .

Any clue ?
Thanks

mod_deflate won't automatically start putting entries in your current
access logs. Read the mod_deflate documentation I sent you earlier, or
at least try searching it for 'log'.

Cheers,
Phil.
