1.本文采用的什么工具压力测试？
2.如何实现压力测试？
3.如何实现压力测试？
前言：现在云服务器是主流，成了许多中小型公司的首选服务器，但是云服务器都是虚拟机，所以性能是一大疑问，这里就开始简单介绍云服务器的性能测试，云端web服务器的压力测试。
Linux下常用的四款Web服务器压力测试工具（http_load、webbench、ab、siege），这里采用apache自带的ab工具来测试。
1，开始安装apache前期准备：
[mw_shl_code=bash,true]yum install gcc* -y
yum install libtool* -y[/mw_shl_code]
1.1，去官网下载apache，http://httpd.apache.org/download.cgi#apache24
下载软件包是：httpd-2.4.12.tar.gz
解压tar -zxvf httpd-2.2.6.tar.gz,完成之后，会在当前目录出现一个httpd-2.2.6目录，然后顺序执行如下命令改名：
[mw_shl_code=bash,true]tar -zxvf httpd-2.2.6.tar.gz
mv httpd-2.2.6 apache
cd apache[/mw_shl_code]
报错APR…问题
设置安装参数,命令如下:
[mw_shl_code=bash,true]./configure –prefix=/usr/local/apache2 –enable-module=so –with-apr=/usr/local/apr –with-apr-util=/usr/local/apr-util[/mw_shl_code]
[mw_shl_code=bash,true][root@bwebhttpd-2.4.12]# ./configure --prefix=/usr/local/apache2 --enable-module=so --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util
checking for chosen layout... Apache
checking for working mkdir -p... yes
checking for grep that handles long lines and -e... /bin/grep
checking for egrep... /bin/grep -E
checking build system type... x86_64-unknown-linux-gnu
checking host system type... x86_64-unknown-linux-gnu
checking target system type... x86_64-unknown-linux-gnu
configure:
configure: Configuring Apache Portable Runtime library...
configure:
checking for APR... configure: error: the --with-apr parameter is incorrect. It must specify an install prefix, a build directory, or an apr-config file.
[root@bwebhttpd-2.4.12]#[/mw_shl_code]
1.2 解决apr not found问题
去http://apr.apache.org/download.cgi下载
wget http://archive.apache.org/dist/apr/apr-1.4.6.tar.gz，然后源码安装
[mw_shl_code=bash,true][root@bwebdata]# cd apr-1.4.6
[root@bwebapr-1.4.6]# ./configure --prefix=/usr/local/apr
[root@bwebapr-1.4.6]# make
[root@bwebapr-1.4.6]# make install [/mw_shl_code]
1.3.解决APR-util not found问题
需要安装apr-util组件：
[mw_shl_code=bash,true][root@bwebdata]# wget http://apache.fayea.com//apr/apr-util-1.5.4.tar.gz
[root@bwebdata]# tar -xvf apr-util-1.5.4.tar.gz
[root@bwebdata]# cd apr-util-1.5.4
[root@bwebapr-util-1.5.4]# ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr/bin/apr-1-config
[root@bwebapr-util-1.5.4]# make
[root@bwebapr-util-1.5.4]# make install[/mw_shl_code]
或者 yum install -y apr-util*
1.4 configure: error: pcre-config for libpcre not found问题
../configure添加了–with-apr=/usr/local/apr –with-apr-util=/usr/local/apr-util仍提示 configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/的错误
查看下是否有pcre参数
[root@bwebhttpd-2.4.12]# ./configure -help | grep pcre
–with-pcre=PATH Use external PCRE library
[root@bwebhttpd-2.4.12]#
没有这个参数，所以需要重新下载安装：
下载pcre，下载地址一：http://sourceforge.net/projects/pcre 下载地址二：http://ftp.exim.llorien.org/pcre/
[mw_shl_code=bash,true][root@bwebdata]# wget http://ftp.exim.llorien.org/pcre/pcre-8.36.tar.gz
--这里因为下载失败，所以重新去csdn资源库下载了pcre的zip包
[root@bwebdata]# unzip pcre-8.36.zip
[root@bwebdata]# cd pcre-8.36
[root@bwebpcre-8.36]# ./configure --prefix=/usr/local/pcre
[root@bwebpcre-8.36]# make
[root@bwebpcre-8.36]# make install [/mw_shl_code]
或者 yum安装也可以：
[mw_shl_code=bash,true][root@bwebhttpd-2.4.12]# yum install -y pcre*[/mw_shl_code]
必要的组件安装完了，我们可以继续源码编译apache了
2 最后编译安装apache
[mw_shl_code=bash,true][root@bwebhttpd-2.4.12]# ./configure --prefix=/usr/local/apache2 --enable-module=so --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --with-included-apr
[root@bwebhttpd-2.4.12]# make
[root@bwebhttpd-2.4.12]# make install [/mw_shl_code]
启动apache
/usr/local/apache2/bin/apachectl start
[mw_shl_code=bash,true][root@bwebhttpd-2.4.12]# /usr/local/apache2/bin/apachectl start
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 172.16.1.4. Set the 'ServerName' directive globally to suppress this message
[root@bwebhttpd-2.4.12]# [/mw_shl_code]
查看下：
在浏览器中输入地址：http://172.16.1.4/，会显示如下信息：
It works!
apache安装完毕后ab命令存放在apache安装目录的bin目录下。如下：
[mw_shl_code=bash,true][root@bwebhttpd-2.4.12]# ll /usr/local/apache2/bin
