如何使ApacheBench支持multi-url的方法

由于标准的ab只支持对单个uri进行压测，不满足实际需要，故做以下修改，使ab支持multi-url。

1、下载Apache httpd相关源码包以及针对ab工具的patch包

wget https://mirrors.tuna.tsinghua.edu.cn/apache/apr/apr-1.6.5.tar.gzwget https://mirrors.tuna.tsinghua.edu.cn/apache/apr/apr-util-1.6.1.tar.gzwget https://mirrors.tuna.tsinghua.edu.cn/apache/httpd/httpd-2.4.37.tar.gzwget https://github.com/philipgloyne/apachebench-for-multi-url/archive/master.zip

注：httpd依赖于apr和apr-util

2、编译安装apr

tar -zxf apr-1.6.5.tar.gzcd apr-1.6.5./configure --prefix=/usr/local/aprmake && make install

3、编译安装apr-util

tar -zxf apr-util-1.6.1.tar.gzcd apr-util-1.6.1./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/aprmake && make install

4、替换httpd源码里面的ab.c文件

unzip master.ziptar -zxf httpd-2.4.37.tar.gz\cp ./apachebench-for-multi-url-master/ab.c ./httpd-2.4.37/support/

5、编译安装httpd

cd httpd-2.4.37./configure               \  --with-apr=/usr/local/apr      \  --with-apr-util=/usr/local/apr-util \  --prefix=/usr/local/apache     \  --sysconfdir=/etc/httpd24      \  --enable-so             \  --enable-ssl            \  --enable-cgi            \  --enable-rewrite          \  --with-zlib             \  --with-pcre             \  --with-mpm=prefork         \  --enable-modules=most        \  --enable-mpms-shared=all make && make install

6、验证结果

#/usr/local/apache/bin/ab -hUsage: /usr/local/apache/bin/ab [options] [http[s]://]hostname[:port]/pathOptions are:  -n requests   Number of requests to perform  -c concurrency Number of multiple requests to make  -t timelimit  Seconds to max. wait for responses  -b windowsize  Size of TCP send/receive buffer, in bytes  -p postfile   File containing data to POST. Remember also to set -T  -u putfile   File containing data to PUT. Remember also to set -T  -T content-type Content-type header for POSTing, eg.          'application/x-www-form-urlencoded'          Default is 'text/plain'  -v verbosity  How much troubleshooting info to print  -w       Print out results in HTML tables  -i       Use HEAD instead of GET  -x attributes  String to insert as table attributes  -y attributes  String to insert as tr attributes  -z attributes  String to insert as td or th attributes  -C attribute  Add cookie, eg. 'Apache=1234. (repeatable)  -H attribute  Add Arbitrary header line, eg. 'Accept-Encoding: gzip'          Inserted after all normal header lines. (repeatable)  -A attribute  Add Basic WWW Authentication, the attributes          are a colon separated username and password.  -P attribute  Add Basic Proxy Authentication, the attributes          are a colon separated username and password.  -X proxy:port  Proxyserver and port number to use  -V       Print version number and exit  -k       Use HTTP KeepAlive feature  -d       Do not show percentiles served table.  -S       Do not show confidence estimators and warnings.  -g filename   Output collected data to gnuplot format file.  -e filename   Output CSV file with percentages served  -r       Don't exit on socket receive errors.  -h       Display usage information (this message)  -L       Use URL list file name, eg. url.txt  -Z ciphersuite Specify SSL/TLS cipher suite (See openssl ciphers)  -f protocol   Specify SSL/TLS protocol (SSL2, SSL3, TLS1, or ALL)

可以看到ab已经支持-L参数（上面帮助信息的倒数第3行），大功告成。
