本机CentOS6.5最大化安装,以下安装所需组件也是最大化安装之后仍需自己安装的.
1.安装libpcap与libpcap-devel
yum -y install libpcap*
2.安装libpcre
yum -y install yum install pcre*
3.安装libdnet
推荐先添加epel源再按装此组件,参考:CentOS6.5 添加epel源
yum -y install libdnet*
4.下载最新版snort,网址 https://www.snort.org/
5.编译安装daq-2.0.2.tar.gz
tar xvfz daq-2.0.2.tar.gz cd daq-2.0.2 ./configure; make; sudo make install
6.编译安装snort-2.9.6.2.tar.gz
tar xvfz snort-2.9.6.2.tar.gz cd snort-2.9.6.2 ./configure --enable-sourcefire; make; sudo make install
