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：
yum install gcc* -y
yum install libtool* -y
1.1，去官网下载
apache，/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：
tar -zxvf httpd-2.2.6.tar.gzmv httpd-2.2.6 apachecd apache
设置安装参数,命令如下:
./configure --prefix=/usr/local/apache2 --enable-module=so --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util
[root@bwebhttpd-2.4.12]# ./configure --prefix=/usr/local/apache2 --enable-module=so --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-utilchecking for chosen layout...

报错APR…问题
1.2 解决apr not found问题
去/download.cgi下载
wget /dist/apr/apr-1.4.6.tar.gz，然后源码安装
[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
1.3.解决APR-util not found问题
需要安装apr-util组件：
[root@bwebdata]# wget //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
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 /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：/projects/pcre 下载地址二：http://ftp./pcre/
[root@bwebdata]# wget http://ftp./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
或者 yum安装也可以：
[root@bwebhttpd-2.4.12]# yum install -y pcre*
**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
[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
启动apache
/usr/local/apache2/bin/apachectl start
[root@bwebhttpd-2.4.12]# /usr/local/apache2/bin/apachectl startAH00558: 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]#
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：
[root@bwebhttpd-2.4.12]# ll /usr/local/apache2/bintotal 2308-rwxr-xr-x. 1 root root 80799 Jun 4 12:48 ab-rwxr-xr-x. 1 root root 3438 Jun 4 12:43 apachectl-rwxr-xr-x. 1 root root 23515 Jun 4 12:43 apxs-rwxr-xr-x. 1 root root 12277 Jun 4 12:48 checkgid-rwxr-xr-x. 1 root root 8925 Jun 4 12:43 dbmmanage-rw-r--r--. 1 root root 1073 Jun 4 12:43 envvars-rw-r--r--. 1 root root 1073 Jun 4 12:43 envvars-std-rwxr-xr-x. 1 root root 0 Jun 4 12:48 fcgistarter-rwxr-xr-x. 1 root root 66594 Jun 4 12:48 htcacheclean-rwxr-xr-x. 1 root root 40674 Jun 4 12:48 htdbm-rwxr-xr-x. 1 root root 22263 Jun 4 12:48 htdigest-rwxr-xr-x. 1 root root 41346 Jun 4 12:48 htpasswd-rwxr-xr-x. 1 root root 1933978 Jun 4 12:48 httpd-rwxr-xr-x. 1 root root 19488 Jun 4 12:48 httxt2dbm-rwxr-xr-x. 1 root root 21908 Jun 4 12:48 logresolve-rwxr-xr-x. 1 root root 34593 Jun 4 12:48 rotatelogs[root@bwebhttpd-2.4.12]#
