将3个压缩包拷贝到root/ntop中：Mv *.tar.gz ntop
进入ntop目录将压缩包解压到/usr/src下：
tar fvxz libpcap-0.8.3.tar.gz -C /usr/src
tar fvxz rrdtool-1.1.13.tar.gz -C /usr/src
tar fvxz ntop-3-3.tar.gz -C /usr/src
进入/usr/src目录，进入/libpcap-0.8.3目录，执行文件./configure
会报错：configure: error: Your operating system's lex is insufficient to compile
libpcap.flex is a lex replacement that has many advantages, including
being able to compile libpcap.For more information, see
http://www.gnu.org/software/flex/flex.html .
说明缺少必要的软件包flex盘镜像 mount /dev/cdrom /mnt/cdrom
安装flex软件包：yum install flex
安装完成后，再次执行./configure,此时可以正常执行
编译并编译安装：make&&make install
编译报错：
make: yacc：命令未找到
make: *** 错误 127
需要安装byacc包：yum install byacc
再次编译，此时可以编译成功，libpcap-0.8.3安装完成！
安装rrdtool-1.2.13:
进入目录/usr/src/rrdtool-1.2.13
执行文件./configure –prefix=/usr/local/,将rrdtool包安装到Local下
报错信息：configure: error: Please fix the library issues listed above and try again.
查找出需要安装的包并通过yum安装：yum install libart-lgpl-devel libxml2-devel pango-devel pango libpng-devel freetype freetype-devel
再次执行./configure –prefix=/usr/local/，此时再次报错：configure: error: Please fix the library issues listed above and try again. 需要安装libart_lgpldevel包：yum install libart_lgpldevel
再次执行./configure-prefix=/usr/local，可以成功执性
编译并编译安装：make&&make install
安装ntop-3.3：
进入目录/usr/src/ntop-3.3
Ntop中有自动执行脚本，自动生成文件并自动配置。并将mysql屏蔽
执行：./autogen.sh –disable-mysql报错：
