无法用yum安装wireless-tools
[root@localhost wireless_tools.29]# yum install -y wireless-tools
Loaded plugins: fastestmirror, langpacks

No package wireless-tools available.
Error: Nothing to do
算了，那就源代码安装吧

解压之后make make install就完成了
既然安装完成了，那很自然就要测试一下
[root@localhost wireless_tools.29]# iwconfig
iwconfig: error while loading shared libraries: libiw.so.29: cannot open shared object file: No such file or directory
奇怪怎么找到不到libiw.so.29
仔细看了一些安装的过程，发现是有libiw.so.29
[root@localhost wireless_tools.29]# make install
install -m 755 -d /usr/local/lib/
install -m 755 libiw.so.29 /usr/local/lib/
ln -sfn libiw.so.29 /usr/local/lib//libiw.so
然后发现后面有一句
Don't forget to add /usr/local/lib/ to /etc/ld.so.conf, and run ldconfig as root
哦，明白了
