去官网（ns2官网链接）下载你要的安装包版本，我下载的是ns-2.35，是2011年发布的。
把压缩包ns-allinone-2.35.tar.gz解压到你要安装的位置，例如路径/home/jin/下，命令为
tar zxvf ns-allinone-2.35.tar.gz /home/jin
然后进入解压目录，安装，命令为
./install
顺利地话，几分钟后安装完毕，系统给出以下信息：
ns-allinone package has been installed successfully.here are the installation places:tcl8.5.10: /home/jin/ns-allinone-2.35/{bin,include,lib}tk8.5.10: /home/jin/ns-allinone-2.35/{bin,include,lib}otcl: /home/jin/ns-allinone-2.35/otcl-1.14tclcl: /home/jin/ns-allinone-2.35/tclcl-1.20ns: /home/jin/ns-allinone-2.35/ns-2.35/nsxgraph: /home/jin/ns-allinone-2.35/xgraph-12.2gt-itm: /home/jin/ns-allinone-2.35/itm, edriver, sgb2alt, sgb2ns, sgb2comns, sgb2hierns----------------------------------------------------------------------------------please put /home/jin/ns-allinone-2.35/bin:/home/jin/ns-allinone-2.35/tcl8.5.10/unix:/home/jin/ns-allinone-2.35/tk8.5.10/unixinto your path environment; so that you'll be able to run itm/tclsh/wish/xgraph.important notices:(1) you must put /home/jin/ns-allinone-2.35/otcl-1.14, /home/jin/ns-allinone-2.35/lib, into your ld_library_path environment variable. if it complains about x libraries, add path to your x libraries into ld_library_path. if you are using csh, you can set it like: setenv ld_library_path if you are using sh, you can set it like: export ld_library_path=(2) you must put /home/jin/ns-allinone-2.35/tcl8.5.10/library into your tcl_library environmental variable. otherwise ns/nam will complain during startup.after these steps, you can now run the ns validation suite withcd ns-2.35; ./validatefor trouble shooting, please first read ns problems page http://www.isi.edu/nsnam/ns/ns-problems.html. also search the ns mailing list archivefor related posts.
按照系统给出的信息，进行以下配置：
export path=$path:/home/jin/ns-allinone-2.35/bin:/home/jin/ns-allinone-2.35/tcl8.5.10/unix:/home/jin/ns-allinone-2.35/tk8.5.10/unixexport ld_library_path=/home/jin/ns-allinone-2.35/bin:/home/jin/ns-allinone-2.35/tcl8.5.10/unix:/home/jin/ns-allinone-2.35/tk8.5.10/unixexport tcl_library=/home/jin/ns-allinone-2.35/tcl8.5.10/library
然后apt-get install ns2apt-get install nam
cd ns-2.35/ ./validate
最后一步需要很长时间，学会等待。。。
执行结束，系统有如下提示：
