Because the standard ab only supports the pressure measurement of a single uri, which does not meet the actual needs, the following modifications are made to make ab support multi-url.

1. Download Apache httpd related source package and patch package for ab tool


Note: httpd depends on apr and apr-util

2. Compile and install apr

tar -zxf apr-1.6.5.tar.gz
cd apr-1.6.5
./configure --prefix=/usr/local/apr
make && make install

3. Compile and install apr-util

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

4. Replace ab. c file in httpd source code

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

5. Compile and install 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        \

make && make install

6. Verification results

#/usr/local/apache/bin/ab -h
Usage: /usr/local/apache/bin/ab [options] [http[s]://]hostname[:port]/path
Options 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.
          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)

You can see that ab already supports the-L parameter (the third last line of the help information above), and you're done.
