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

./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-1.14
tclcl:	/home/jin/ns-allinone-2.35/tclcl-1.20
ns:	/home/jin/ns-allinone-2.35/ns-2.35/ns
xgraph:	/home/jin/ns-allinone-2.35/xgraph-12.2
gt-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/unix
into 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 with
cd ns-2.35; ./validate

For trouble shooting, please first read ns problems page 
http://www.isi.edu/nsnam/ns/ns-problems.html. Also search the ns mailing list archive
for 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/unix"
export 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/unix"
export TCL_LIBRARY="/home/jin/ns-allinone-2.35/tcl8.5.10/library"

apt-get install ns2
apt-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：

validate overall report: some tests failed:
 ./test-all-newreno ./test-all-tcpOptions ./test-all-tcpVariants ./test-all-aimd ./test-all-frto ./test-all-quickstart ./test-all-manual-routing ./test-all-links
to re-run a specific test, cd tcl/test; ./test-all-TEST-NAME
