mod_ruid2 installation

yum install libcap-devel
cd /usr/local/src
wget http://downloads.sourceforge.net/project/mod-ruid/mod_ruid2/mod_ruid2-0.9.4.tar.bz2
tar -jxf mod_ruid2-0.9.4.tar.bz2
cd mod_ruid2-0.9.4
vi ruid2.conf
LoadModule ruid2_module modules/mod_ruid2.so

RMode config
RDefaultUidGid nobody nobody
RUidGid nobody nobody
RGroups nobody

apxs -a -i -l cap -c mod_ruid2.c

Open httpd.conf and remove the line from it:

LoadModule ruid2_module modules/mod_ruid2.so

echo "LoadModule ruid2_module modules/mod_ruid2.so" >> /usr/local/apache/conf/includes/pre_main_global.conf
/usr/local/cpanel/bin/apache_conf_distiller --update
/etc/init.d/httpd restart

In future, /scripts/easyapache recompiles will move the file mod_ruid2.so out of /usr/local/apache/modules folder.
So save a copy of it.

cp /usr/local/apache/modules/mod_ruid2.so /root

vi /scripts/preeasyapache
#!/bin/bash

sed -i 's/LoadModule ruid2_module/#LoadModule ruid2_module/g' /usr/local/apache/conf/includes/pre_main_global.conf

vi /scripts/posteasyapache
#!/bin/bash

cp /root/mod_ruid2.so /usr/local/apache/modules/
sed -i 's/#LoadModule ruid2_module/LoadModule ruid2_module/g' /usr/local/apache/conf/includes/pre_main_global.conf
/etc/init.d/httpd restart

chmod +x /scripts/preeasyapache
chmod +x /scripts/posteasyapache
