前一段一直在做snort入侵检测系统的安装以及配置，看了很多的网上资料，也算是总结了下前辈的经验吧。
需要的软件包：
1、httpd-2.2.6.tar.gz
2、mysql-5.1.22-rc-linux-i686-icc-glibc23.tar.gz
3、php-5.2.4.tar.bz2
4、acid-0.9.6b23.tar.gz
4、acid-0.9.6b23.tar.gz
5、adodb4991.tgz
6、jpgraph-1.26.tar.gz
7、libpcap-1.0.0.tar.gz
8、pcre-7.8.tar.gz
9、snort-2.8.3.1.tar.gz
10、snortcenter-agent-v1.0-RC1.tar.gz
11、snortcenter-v1.0-RC1.tar.gz
12、zlib-1.2.3.tar.gz
关于apache，php，mysql的安装看另外的文档
一、安装snort的支持包
1、安装libpcap包
# tar zxvf libpcap-0.7.2.tar.gz
# cd libpcap-0.7.2
# ./configure
# make
# make install
2、安装pcre包
# tar zxvf pcre-7.8.tar.gz
# ./configure
# make
# make install
3、安装zlib包
# tar zxvf zlib-1.2.3.tar.gz
# ./configure
# make
# make install
二、安装snort
# tar zxvf snort-2.8.3.1.tar.gz
# cd snort-2.8.3.1
# ./configure --with-mysql=/usr/local/mysql
# make
# make install
# cd preproc_rules
# mkdir /etc/snort
# mkdir /var/log/snort
# cp * /etc/snort
# cd ../etc
# cp snort.conf /etc/snort
# cp *.config /etc/snort
# cd
# vi /etc/snort/snort.conf
<!--[if !supportLineBreakNewLine]-->
<!--[endif]-->
<!--[if !supportLineBreakNewLine]-->
<!--[endif]-->
“# var HOME_NET 10.1.1.0/24”改成“var HOME_NET 192.168.0.0/24”你自己LAN内的地址，把前面的#号去掉。
“var RULE_PATH ../rules”改成“var RULE_PATH /etc/snort”
#output database: log, mysql, user=root password=test dbname=db host=localhost”
“output database: log, mysql, user=root password=123456 dbname=snort host=localhost” 密码改成你自己的，把前面的#号去掉。
把
# include $RULE_PATH/web-attacks.rules
# include $RULE_PATH/backdoor.rules
# include $RULE_PATH/shellcode.rules
# include $RULE_PATH/policy.rules
# include $RULE_PATH/porn.rules
# include $RULE_PATH/info.rules
# include $RULE_PATH/icmp-info.rules
include $RULE_PATH/virus.rules
# include $RULE_PATH/chat.rules
# include $RULE_PATH/multimedia.rules
# include $RULE_PATH/p2p.rules //前面的#号删除。
修改完毕后，保存退出。
三、建立snort数据库
# /usr/local/mysql/bin/mysql -uroot -p123456
# create database snort;
# grant INSERT,SELECT on root.* to snort@localhost;
# exit
# cd /usr/local/src/snort-2.8.3.1/schemas # /usr/local/mysql/bin/mysql -uroot -p123456 < create_mysql snort
# 进入mysql数据库，看看snort数据库中的表：
# /usr/local/mysql/bin/mysql -uroot -p123456
<!--[if !supportLineBreakNewLine]-->
<!--[endif]-->
<!--[if !supportLineBreakNewLine]-->
<!--[endif]-->
mysql>show databases;
+------------+
| Database
+------------+
| mysql
| snort
| test
+------------+
3 rows in set (0.00 sec)
mysql>use snort;
mysql>show tables; 将会有这些：
+------------------+
| Tables_in_snort |
+------------------+
| data
| detail
| encoding
| event
| flags
| icmphdr
| iphdr
| opt
| protocols
| reference
| reference_system
| schema
| sensor
| services
| sig_class
| sig_reference
| signature
| tcphdr
| udphdr
+------------------+
19 rows in set (0.00 sec)
mysql>exit

snort的chkconfig管理
cd /root/snort-2.8.3.1/rpm
cp snortd /etc/init.d/
chmod 755 /etc/init.d/snortd
chkconfig --add snortd
chkconfig --level 35 snortd on
四、安装设置Acid
# 把acid-0.9.6b23.tar.gz、adodb4991.tgz、jpgraph-1.26.tar.gz放到网页根目录，我这里是默认的。
# cp a*.* /usr/local/apache2/htdocs
# cp jpgraph-1.26.tar.gz /usr/local/apache2/htdocs
# tar zxvf adodb4991.tgz
# tar zxvf jpgraph-1.26.tar.gz
# mv jpgraph-1.26 jpgraph
# tar zxvf acid-0.9.6b23.tar.gz
# cd acid
# vi acid_conf.php
把“$DBlib_path = "";” 改成“$DBlib_path = "/usr/local/apache2/htdocs/adodb”
# $alert_dbname = "snort_log"; //改成snort
$alert_host = "localhost";
$alert_port = "";
$alert_user = "root";
$alert_password = "mypassword"; //改成你的数据库密码
/* Archive DB connection parameters */
$archive_dbname = "snort_archive"; //改成snort
$archive_host = "localhost";
$archive_port = "";
$archive_user = "root";
$archive_password = "mypassword";” //改成你的数据库密码
# 把“$ChartLib_path = "";” 改成“$ChartLib_path = "/usr/local/apache2/htdocs/jpgraph/src”
# 修改完毕后，保存退出。
# mv jpgraph-1.26 jpgraph
# tar zxvf acid-0.9.6b23.tar.gz
# cd acid
# vi acid_conf.php
把“$DBlib_path = "";” 改成“$DBlib_path = "/usr/local/apache2/htdocs/adodb”
# $alert_dbname = "snort_log"; //改成snort
$alert_host = "localhost";
$alert_port = "";
$alert_user = "root";
$alert_password = "mypassword"; //改成你的数据库密码
/* Archive DB connection parameters */
$archive_dbname = "snort_archive"; //改成snort
$archive_host = "localhost";
$archive_port = "";
$archive_user = "root";
$archive_password = "mypassword";” //改成你的数据库密码
# 把“$ChartLib_path = "";” 改成“$ChartLib_path = "/usr/local/apache2/htdocs/jpgraph/src”
# 修改完毕后，保存退出。
六、进入web界面：
# http://yourhost/acid/acid_main.php，点"Setup Page"链接 ->Create Acid AG
# 访问http://yourhost/acid将会看到ACID界面。
# 访问http://yourhost/acid将会看到ACID界面。
七、测试IDS
# 利用nmap,nessus,CIS或X-scan对系统进行扫描，产生告警纪录。
# http://yourhost/acid 察看纪录。
# 至此，一个功能强大的IDS设置完毕。各位能利用web界面远程登陆，监视主机所处局域网，同时安装 phpMyAdmin或webmin对mysql数据库进行操控
# http://yourhost/acid 察看纪录。

八、安装SnortCenter
# cp snortcenter-v1.0-RC1.tar.gz /usr/local/apache2/htdocs
# tar zxvf snortcenter-v1.0-RC1.tar.gz
# mv www sc
# vi sc/config.php
# 改以下内容：
$DBlib_path = "/usr/local/apache2/htdocs/adodb/
$curl_path = "/usr/bin";
$DBtype = "mysql";
$DB_dbname = "snortcenter"; # $DB_dbname : MySQL database name of
SnortCenter DB
$DB_host = "localhost"; # $DB_host : host on which the DB is
stored
$DB_user = "root"; # $DB_user : login to the database w
ith this user
$DB_password = "123456"; # $DB_password : password of the
DB user
$DB_port = ""; # $DB_port : port on which to access
the DB (blank is default)
（数据库密码改成你自己的）
# 修改好后，保存退出。
# 然后创建snortcenter的数据库
# mysql -uroot -p123456
# create database snortcenter;
# quit;
# 在浏览器上键入http://192.168.0.11/sc，他会自动创建数据表，然后再次登入会让你输入用户名和密码，初始是admin,change.
# tar zxvf snortcenter-v1.0-RC1.tar.gz
# mv www sc
# vi sc/config.php
# 改以下内容：
$DBlib_path = "/usr/local/apache2/htdocs/adodb/
$curl_path = "/usr/bin";
$DBtype = "mysql";
$DB_dbname = "snortcenter"; # $DB_dbname : MySQL database name of
SnortCenter DB
$DB_host = "localhost"; # $DB_host : host on which the DB is
stored
$DB_user = "root"; # $DB_user : login to the database w
ith this user
$DB_password = "123456"; # $DB_password : password of the
DB user
$DB_port = ""; # $DB_port : port on which to access
the DB (blank is default)
（数据库密码改成你自己的）
# 修改好后，保存退出。
# 然后创建snortcenter的数据库
# mysql -uroot -p123456
# create database snortcenter;
# quit;
# 在浏览器上键入http://192.168.0.11/sc，他会自动创建数据表，然后再次登入会让你输入用户名和密码，初始是admin,change.
CREATE TABLE dbname.schema (vseq int(10) unsigned NOT NULL default '0',ctime datetime NOT NULL default '0000-00-00 00:00:00') TYPE=MyISAM;
# 然后我们安装snortcenter-agent-v1.0-RC1.tar.gz
# cp snortcenter-agent-v1.0-RC1.tar.gz /opt
# cd /opt
# tar zxvf snortcenter-agent-v1.0-RC1.tar.gz
# cd sensor
# ./setup.sh，回答几个问题即完成安装，默认端口2525。
# cp /etc/snort.conf /etc/snort.eth0.conf
# 然后我们安装snortcenter-agent-v1.0-RC1.tar.gz
# cp snortcenter-agent-v1.0-RC1.tar.gz /opt
# cd /opt
# tar zxvf snortcenter-agent-v1.0-RC1.tar.gz
# cd sensor
# ./setup.sh，回答几个问题即完成安装，默认端口2525。
# cp /etc/snort.conf /etc/snort.eth0.conf
