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.gz wget https://mirrors.tuna.tsinghua.edu.cn/apache/apr/apr-util-1.6.1.tar.gz wget https://mirrors.tuna.tsinghua.edu.cn/apache/httpd/httpd-2.4.37.tar.gz wget 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.gz cd apr-1.6.5 ./configure --prefix=/usr/local/apr make && make install
3、编译安装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、替换httpd源码里面的ab.c文件
unzip master.zip tar -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 -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. '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。

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!
昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。
这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。
而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
