e.让apache在以运行级3、5启动的时候能够自动运行

　　[root@netserver php-4.3.3]#cp apachectl /etc/init.d/httpd
　　[root@netserver php-4.3.3]#chmod 755 /etc/init.d/httpd
　　[root@netserver php-4.3.3]# ln -s /etc/init.d/httpd /etc/rc3.d/s85httpd
　　[root@netserver php-4.3.3]# ln -s /etc/init.d/httpd /etc/rc3.d/k85httpd
　　[root@netserver php-4.3.3]# ln -s /etc/init.d/httpd /etc/rc5.d/s85httpd
　　[root@netserver php-4.3.3]# ln -s /etc/init.d/httpd /etc/rc5.d/k85httpd
　　[root@netserver php-4.3.3]#cd ../

　　然后在浏览器输入 http://该机ip地址/test.php 查看关于apache/php的信息

　　7、安装snort和过滤规则

　　a. 编译安装snort

　　[root@netserver ids]#groupadd snort
　　[root@netserver ids]#useradd -g snort snort
　　[root@netserver ids]#mkdir /etc/snort
　　[root@netserver ids]#mkdir /etc/snort/rules
　　[root@netserver ids]#mkdir /var/log/snort
　　[root@netserver ids]#tar -xvzf snort-2.0.2.tar.gz
　　[root@netserver ids]#cd snort-2.0.2
　　[root@netserver snort-2.0.2]#./configure --with-mysql=/usr/local/mysql --enable-flexresp --with-libpcap-includes=/usr/local/libpcap/include --with-libpcap-libraries=/usr/local/libpcap/lib (此语句请写成一行)
　　[root@netserver snort-2.0.2]#make
　　[root@netserver snort-2.0.2]#make install

　　b. 设置规则，我们这里为了方便，直接使用snort自带的规则

　　[root@netserver snort-2.0.2]#cp rules/* /etc/snort
　　[root@netserver snort-2.0.2]#cp etc/.conf /etc/snort
　　[root@netserver snort-2.0.2]#cp *.conf /etc/snort

　　c.编辑snort.conf文件

　　[root@netserver snort-2.0.2]#vi /etc/snort/snort.conf

　　将以下几行的值改变为所写的：

　　var rule_path /etc/snort/rules/
　　output database: log, mysql, user=snort password=(你的密码) dbname=snort host=localhost

　　d.让snort在以运行级3、5启动的时候能够自动运行

　　snort. (cp contrib/s99snort /etc/init.d/snort) change the following lines:
　　[root@netserver snort-2.0.2]#cp contrib/s99snort /etc/init.d/snort

　　编辑snort文件，修改下面两行

　　[root@netserver snort-2.0.2]#vi /etc/init.d/snort
　　config=/etc/snort/snort.conf
　　snort_gid=snort

　　[root@netserver snort-2.0.2]#chmod 755 /etc/init.d/snort
　　[root@netserver snort-2.0.2]#ln -s /etc/init.d/snort /etc/rc3.d/s99snort
　　[root@netserver snort-2.0.2]#ln -s /etc/init.d/snort /etc/rc3.d/k99snort
　　[root@netserver snort-2.0.2]#ln -s /etc/init.d/snort /etc/rc5.d/s99snort
　　[root@netserver snort-2.0.2]#ln -s /etc/init.d/snort /etc/rc5.d/k99snort

　　e.在mysql中设置snort需要的库

　　[root@netserver snort-2.0.2]#/usr/local/mysql/bin/mysql
　　mysql＞ set password for root@localhost=password('你的root的密码')；
　　＞query ok, 0 rows affected (0.25 sec)
　　mysql＞ create database snort；
　　＞query ok, 1 row affected (0.01 sec)
　　mysql＞ grant insert,select on root.* to snort@localhost；
　　＞query ok, 0 rows affected (0.02 sec)
　　mysql＞ set password for snort@localhost=password('你的snort的密码')
　　＞query ok, 0 rows affected (0.25 sec)
　　mysql＞ grant create, insert, select, delete, update on snort.* to snort@localhost
　　＞query ok, 0 rows affected (0.02 sec)
　　mysql＞ grant create, insert, select, delete, update on snort.* to snort
　　＞query ok, 0 rows affected (0.02 sec)
　　mysql＞ exit
　　＞bye
