测试了linux下的几种压力测试工具，发现有些不支持https，先简单总结如下：
一、apache的ab工具
/home/webadm/bin/ab -c 50 -n 10000 https://2hei.net/mt/index.html
SSL not compiled in; no https support
看样子是说SSL没有编译进来，所以不支持https
二、apache的flood工具
http://httpd.apache.org/test/flood/wget http://www.apache.org/dist/httpd/flood/flood-0.4.tar.gz
如果要支持https的话，需要添加如下的编译参数：–with-apr –with-apr-util –enable-ssl
具体代码也可以从svn获取。
不过我在编译的时候遇到一些问题，apr-util包在make的时候总是报错！
三、web-bench工具
http://freshmeat.net/projects/web-bench/./webbench -c 20 -t 10 https://2hei.net/mt/index.html
Webbench – Simple Web Benchmark 1.5
Copyright (c) Radim Kolar 1997-2004, GPL Open Source Software.Only HTTP protocol is directly supported, set –proxy for others.
明确提示了提示不支持https哦！
四、http_load工具，曾经的最爱，http测试的结果还很令人满意。
http://acme.com/software/http_load/
./http_load -rate 5 -seconds 10 urls
./http_load: unknown protocol – https://2hei.net/mt/index.html
吼吼，看来之前常用的http_load也不支持https
五、siege工具
http://www.joedog.org/index/siege-home编译使之支持https
./configure –prefix=/home/2hei.net/siege –with-ssl=/usr/include/openssl基本用法：
./siege
SIEGE 2.69
Usage: siege [options]
siege [options] URL
siege -g URL
Options:
-V, –version VERSION, prints version number to screen.
-h, –help HELP, prints this section.
-C, –config CONFIGURATION, show the current configuration.
-v, –verbose VERBOSE, prints notification to screen.
-g, –get GET, pull down headers from the server and display HTTP
transaction. Great for web application debugging.
-c, –concurrent=NUM CONCURRENT users, default is 10
-u, –url=”URL” Deprecated. Set URL as the last argument.
-i, –internet INTERNET user simulation, hits the URLs randomly.
-b, –benchmark BENCHMARK, signifies no delay for time testing.
-t, –time=NUMm TIME based testing where “m” is the modifier S, M, or H
no space between NUM and “m”, ex: –time=1H, one hour test.
-r, –reps=NUM REPS, number of times to run the test, default is 25
-f, –file=FILE FILE, change the configuration file to file.
-R, –rc=FILE RC, change the siegerc file to file. Overrides
the SIEGERC environmental variable.
-l, –log LOG, logs the transaction to PREFIX/var/siege.log
-m, –mark=”text” MARK, mark the log file with a string separator.
-d, –delay=NUM Time DELAY, random delay between 1 and num designed
to simulate human activity. Default value is 3
-H, –header=”text” Add a header to request (can be many)
-A, –user-agent=”text” Sets User-Agent in requestsiege -c 20 -r 2 -f url
-c 20 并发20个用户
-r 2 重复循环2次
-f url 任务列表：URL列表结论相当凑合，纵欲找到可以支持https压力测试的工具了。
六、httperf工具，来自hp的工具，不过已经n年没有更新了。
wget ftp://ftp.hpl.hp.com/pub/httperf/httperf-0.9.0.tar.gz$ mkdir build
$ cd build
$ SRCDIR/configure
$ make
$ make install工具使用方法：
/usr/local/bin/httperf –help
Usage: httperf [-hdvV] [--add-header S] [--burst-length N] [--client N/N]
[--close-with-reset] [--debug N] [--failure-status N]
[--help] [--hog] [--http-version S] [--max-connections N]
[--max-piped-calls N] [--method S] [--no-host-hdr]
[--num-calls N] [--num-conns N] [–period [d|u|e]T1[,T2]]
[--port N] [–print-reply [header|body]] [–print-request [header|body]]
[--rate X] [--recv-buffer N] [--retry-on-failure] [--send-buffer N]
[--server S] [--server-name S] [--session-cookies]
[--ssl] [--ssl-ciphers L] [--ssl-no-reuse]
[--think-timeout X] [--timeout X] [--uri S] [--verbose] [--version]
[--wlog y|n,file] [--wsess N,N,X] [--wsesslog N,X,file]
[--wset N,X]
如：
/usr/local/bin/httperf –server www.2hei.net
–port 443 –uri /mt/index.html
–rate 15 –num-conn 1000
–num-call 1 –timeout 5发现会有如下错误：
httperf: warning: open file limit > FD_SETSIZE; limiting max. # of open files to FD_SETSIZE
以下是解决办法：
# Edit /etc/security/limits.conf and add the line * hard nofile 65535 (or instead of * you can put the username of the user for whom you want to change the limit)
# Edit /usr/include/bits/typesizes.h and change #define __FD_SET_SIZE 1024 to #define __FD_SET_SIZE 65535 (in /usr/include/sys/select.h FD_SETSIZE is defined as __FD_SETSIZE)
重新编译即可。实例测试如下：
/usr/local/bin/httperf –client=0/1 –ssl –server=www.2hei.net –port=443 –uri=/mt/index.html –rate=1 –num-conns=1000 –rate=50 –num-calls=1 –hog
httperf –hog –client=0/1 –server=www.2hei.net –port=443 –uri=/mt/index.html –rate=50 –send-buffer=4096 –rec
v-buffer=16384 –ssl –num-conns=1000 –num-calls=1
