How to enable mod_deflate on Apache 2.4

Filed under: Apache — Tags: 2.4, Apache, gzip, mod_deflate — admin @ 7:02 am

Well, I am writing this guide because enabling mod_deflate on Apache 2.4 has become more complex than enabling a single module like it was on Apache 2.2
Now you have to enable 3 modules in httpd.conf for mod_deflate to work properly :

LoadModule deflate_module modules/mod_deflate.so
LoadModule headers_module modules/mod_headers.so
LoadModule filter_module modules/mod_filter.so

Also you have to enable compression by this config :

AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css text/javascript application/javascript
DeflateCompressionLevel 9

Auto update Atomicorp mod_security rules script

Filed under: cPanel,linux — Tags: atomicorp, modsec, mod_security, script, update — admin @ 6:31 pm

Here is a very simple script, I have written for my own use to auto update mod_security rules from Atomicorp server. You can use cronjobs to automate the process.
Dont forget to put your Atomicorp subscription username and password in the script.

#!/bin/sh

USER=
PASS=
DIR=/var/cpanel

VER=`wget -q --user=$USER --password=$PASS http://updates.atomicorp.com/channels/rules/subscription/VERSION -O - | grep MODSEC_VERSION | sed -r 's/^.{15}//'`
FILE_NAME=modsec-$VER.tar.bz2
wget -q --user=$USER --password=$PASS http://updates.atomicorp.com/channels/rules/subscription/$FILE_NAME -O - | tar jxf - -C $DIR
/etc/init.d/httpd -k graceful

In this case, the script will install the rules in /var/cpanel/modsec directory and reload the server gracefully.
Apparently you should have the following in your modsec2.user.conf
