源碼方式安裝
wget https://www.snort.org/downloads/snort/daq-2.0.6.tar.gz tar xvzf daq-2.0.6.tar.gz cd daq-2.0.6 ./configure && make && sudo make install wget https://www.snort.org/downloads/snort/snort-2.9.15.tar.gz tar xvzf snort-2.9.15.tar.gz cd snort-2.9.15 ./configure --enable-sourcefire && make && sudo make install參考：https://www.snort.org/#get-started CentOS Fedora FreeBSD可以參考上方官方文檔安裝
安裝過程中常見問題
1.安裝daq時遇到
configure: error: Your operating system's lex is insufficient to compile libsfbpf. You should install both bison and flex. flex is a lex replacement that has many advantages, including being able to compile libsfbpf. For more information, see
http://www.gnu.org/software/flex/flex.html
解決方式
CentOS
yum install flex bison -y
Ubuntu
apt-get install flex bison
2.安裝snort時時遇到
ERROR! Libpcre header not found. Get it from
http://www.pcre.org
解決方式
Ubuntu：sudo apt-get install libpcre3-dev
CentOS：sudo yum install pcre-devel
3.安裝snort時遇到
ERROR! dnet header not found, go get it from
http://code.google.com/p/libdnet/or use the --with-dnet-* options, if you have it installed in an unusual place
解決方式
wget https://nchc.dl.sourceforge.net/project/libdnet/libdnet/libdnet-1.11/libdnet-1.11.tar.gz tar -zxf libdnet-1.11.tar.gz cd libdnet-1.11 ./configure && make && make install4.安裝snort時遇到
ERROR! LuaJIT library not found. Go get it from
http://www.luajit.org/(or) Try compiling without openAppId using '--disable-open-appid'
解決方式：
sudo wget http://luajit.org/download/LuaJIT-2.0.5.tar.gz sudo tar -zxvf LuaJIT-2.0.5.tar.gz cd LuaJIT-2.0.5/ sudo make && sudo make install5.運行snort時遇到
snort: error while loading shared libraries: libdnet.1: cannot open shared object file: No such file or directory
解決方式：
方法一（未驗證）：
第一步：export LD_LIBRARY_PATH=/usr/local/lib;
第二步：運行/sbin/ldconfig命令更新/etc/ld.so.cache;
注意：可以通過命令echo $LD_LIBRARY_PATH來查看設置內容
方法二：
創建一個符號鏈接：sudo ln -s /usr/local/lib/libdnet.1 /usr/lib/libdnet.1
原因：
1.liddnet.1文件在/usr/local/lib目錄下，但是系統默認的裝載庫路徑卻沒有這個．
2.為了加快程序執行時對共享庫的定位速度，避免使用搜索路徑，直接讀取庫列表文件/etc/ld.so.cache．
