Linux Webbench 编译报错: /bin/sh: ctags: command not found

在安装编译webbench的时候，出现如下错误信息

ctags *.c
install -s webbench /usr/local/bin
install -m 644 webbench.1 /usr/local/man/man1
install: 无法创建普通文件"/usr/local/man/man1": 没有那个文件或目录
make: *** [install] 错误 1

意思是说缺少ctags命令,我没有装了,运行以下命令即可

#: yum install ctags

#: mkdir /usr/local/man -p

webbench

webbench是Linux下的一个网站压力测试工具，最多可以模拟3万个并发连接去测试网站的负载能力。下载地址可以到google搜，我这里给出一个
下载地址：http://soft.vpser.net/test/webbench/webbench-1.5.tar.gz
这个程序更小，解压后不到50K，呵呵

安装
#tar zxvf webbench-1.5.tar.gz
#cd webbench-1.5
#make && make install
会在当前目录生成webbench可执行文件，直接可以使用了

用法：
webbench -c 并发数 -t 运行测试时间 URL
如：
webbench -c 5000 -t 120 http://www.163.com

PS:关于ctags信息,可以运行命令了解一下

NAME
       ctags - Generate tag files for source code

SYNOPSIS
       ctags [options] [file(s)]

       etags [options] [file(s)]

DESCRIPTION
       The  ctags  and etags programs (hereinafter collectively referred to as
       ctags, except where distinguished) generate an index  (or  "tag")  file
       for  a  variety  of  language  objects found in file(s).  This tag file
       allows these items to be quickly and easily located by a text editor or
       other  utility.  A "tag" signifies a language object for which an index
       entry is available (or, alternatively, the index entry created for that
       object).

       Alternatively,  ctags  can generate a cross reference file which lists,
       in human readable form, information about the  various  source  objects
       found in a set of language files.

      Tag index files are supported by numerous editors, which allow the user
       to locate the object associated with a name appearing in a source  file
       and jump to the file and line which defines the name. Those known about
       at the time of this release are:

           Vi(1) and its derivatives (e.g. Elvis, Vim,  Vile,  Lemmy),  CRiSP,
           Emacs, FTE (Folding Text Editor), JED, jEdit, Mined, NEdit (Nirvana
           Edit), TSE (The SemWare Editor), UltraEdit, WorkSpace, X2, Zeus

       Ctags is capable of generating different kinds of tags for each of many
       different  languages.  For  a complete list of supported languages, the
       names by which they are recognized, and the kinds  of  tags  which  are
       generated  for each, see the --list-languages and --list-kinds options.
