最小化安装centos后安装iftop

下载iftop软件

tar -zxvf  iftop-0.17.tar.gz

cd  iftop-0.17

./configure

./configure过程中出现类似下文错误

（1）checking whether make sets ${MAKE}... no

          checking for gcc... no           checking for cc... no           checking for cc... no           checking for cl... no           configure: error: no acceptable C compiler found in $PATH

没有安装gcc导致该问题，yum -y install gcc 安装gcc即可

（2）重新./configure又报如下错误

       checking where to find pcap.h... no idea

       configure: error: can't find pcap.h        You're not going to get very far without libpcap.  

        缺少libpcap libpcap-devel这两个包，

        yum -y  install libpcap libpcap-devel 进行安装

（3）再次编译报如下错误

   checking for a curses library containing mvchgat... none found

   configure: error: Curses! Foiled again!    (Can't find a curses library supporting mvchgat.)    Consider installing ncurses.

   yum  -y install ncurses-devel安装缺少文件

-bash: make: command not found

没有安装make导致该问题，yum -y install make 安装make即可

yum安装完make之后，执行make命令如果出错，重新.configure文件，make && make install

 

 最后iftop命令查看网卡流量信息
