install and configure base(basic analysis and security engine and adodb)
use the following commmand to install php_pear and some additional supporting files to allow for
graphing within base to function properly:
#yum -y install php-pear_number_roman php-pear_numbers_words php-pear_image_color php-pear_canvas
php-pear_image_graph
wget http://pear.php.net/go-pear.phar
php go-pear.phar

Installing Barnyard2
barnyard2 improves the efficicency of snort by reducing the load on the main detection engine by allowing
barnyard2 to handle the inserting of events into the mysql database.
wget https://download.github.com/firnsy-barnyard2-v2-1.9-12-g01f5581.tar.gz
tar -xzvf firnsy-barnyard2-v2-1.9-12-g01f5581.tar.gz
cd firnsy-barnyard2-01f5581
./configure --with-mysql
(if building for centos 64 bit use the following instead -> ./configure --with-mysql-libraries=/usr/lib64/mysql/)
make
make install
cp etc/barnyard2.conf /etc/snort/
mkdir /var/log/barnyard2
chmod 666 /var/log/barnyard2
touch /var/log/snort/barnyard2.waldo
chown snort:snort /var/log/snort/barnyard2.waldo
Edit /etc/snort/barnyard2.conf and modify the following lines.
#config hostname:thor
#config interface:eth0
#output database:log,mysql,user=root password=test dbname=db host=localhost
Remove the#sign from the lines above and change to the below:
config hostname:localhost
config interface:eth0(if using multiple interfaces this should be eth1)
output database:log,mysql,user=snort password=‘password created in mysql section above for snort user‘ dbname=snort host=localhost
testing snort:
you can lauch snort from the commmand line to make sure that it loads properly. Enter the following command:
/usr/local/bin/snort -u snort -g snort -c /etc/snort/snort.conf -i eth0
(如果出现报错：/usr/local/bin/snort: error while loading shared libraries: libdnet.1: cannot open shared object file: No such file or directory
ln -s /usr/local/lib/libdnet.1 /usr/lib/libdnet.1
ln -s /usr/local/lib64/libdnet.1 /usr/lib/libdnet.1）
/usr/local/bin/barnyard2 -c /etc/snort/barnyard2.conf -d /var/log/snort -f snort.log -w /var/log/snort/barnyard2.waldo -D
setting up snort $barnyard2 to start automatically:
ERROR: parser.c(5161) Could not stat dynamic module path "/usr/local/lib/snort_dynamicrules": No such file or directory.
Quick solution :
mkdir /usr/local/lib/snort_dynamicrules
cd /usr/local/lib/snort_dynamicrules
copy all .so of rules or the ones that snort wants (depends on your configuration)
ERROR: OpenAlertFile() => fopen() alert file /var/log/snort/alert: No such file or directory
Quick solution:
mkdir /var/log/snort
vim /var/log/snort/alert
OK
edit /etc/rc.loacl
#ifconfig eth0 up
/usr/local/bin/snort -u snort -g snort -c /etc/snort/snort.conf -i eth0
/usr/local/bin/barnyard2 -c /etc/snort/barnyard2.conf -d /var/log/snort -f snort.log -w /var/log/snort/barnyard2.waldo -D
/etc/rc.local start
