前言：如今，云server主流。它已成为许多中小型企业的首选server，但是云server它是一个虚拟机。所以性能是一个大问题，从这里开始介绍云server性能测试，云webserver压力测试。

Linux下经常使用的四款Webserver压力測试工具（http_load、webbench、ab、siege），这里採用apache自带的ab工具来測试。

1，開始安装apache

前期准备：

yum install gcc* -y

yum install libtool* -y

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,完毕之后，会在当前文件夹出现一个httpd-2.2.6文件夹，然后顺序运行例如以下命令改名：

tar -zxvf httpd-2.2.6.tar.gz

mv httpd-2.2.6 apache

cd apache

设置安装參数,命令例如以下:

./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-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.

报错APR…问题

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。然后源代码安装

[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

须要安装apr-util组件：

[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

或者 yum install -y apr-util*

1.4 configure: error: pcre-config for libpcre not found问题

../configure加入了–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參数

[root@bwebhttpd-2.4.12]# ./configure -help | grep pcre

–with-pcre=PATH Use external PCRE library

[root@bwebhttpd-2.4.12]#

没有这个參数。所以须要又一次下载安装：

下载pcre，下载地址一：http://sourceforge.net/projects/pcre 下载地址二：http://ftp.exim.llorien.org/pcre/

[root@bwebdata]# wget http://ftp.exim.llorien.org/pcre/pcre-8.36.tar.gz

--这里由于下载失败。所以又一次去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安装也能够：

[root@bwebhttpd-2.4.12]# yum install -y pcre*

必要的组件安装完了。我们能够继续源代码编译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 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]#

查看下：

在浏览器中输入地址：http://172.16.1.4/，会显演示样例如以下信息：

It works!

apache安装完毕后ab命令存放在apache安装文件夹的bin文件夹下。例如以下：

[root@bwebhttpd-2.4.12]# ll /usr/local/apache2/bin
