前言：現在云服務器是主流，成了許多中小型公司的首選服務器，但是云服務器都是虛擬機，所以性能是一大疑問，這里就開始簡單介紹云服務器的性能測試，云端web服務器的壓力測試。

Linux下常用的四款Web服務器壓力測試工具（http_load、webbench、ab、siege），這里采用apache自帶的ab工具來測試。

1，開始安裝apache

前期準備：
yum install gcc* -y
yum install libtool* -y

1.1，去官網下載

apache，http://httpd.apache.org/download.cgi#apache24
下載軟件包是：httpd-2.4.12.tar.gz

解壓tar -zxvf httpd-2.2.6.tar.gz,完成之后，會在當前目錄出現一個httpd-2.2.6目錄，然后順序執行如下命令改名：

tar -zxvf httpd-2.2.6.tar.gz mv httpd-2.2.6 apache cd apache

設置安裝參數,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-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]#

報錯APR…問題

1.2 解決apr not found問題

去http://apr.apache.org/download.cgi下載
wget http://archive.apache.org/dist/apr/apr-1.4.6.tar.gz，然后源碼安裝

[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.解決APR-util not found問題

需要安裝apr-util組件：

[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問題

…/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/的錯誤

查看下是否有pcre參數
[root@bwebhttpd-2.4.12]# ./configure -help | grep pcre
–with-pcre=PATH Use external PCRE library
[root@bwebhttpd-2.4.12]#

沒有這個參數，所以需要重新下載安裝：
下載pcre，下載地址一：http://sourceforge.net/projects/pcre 下載地址二：http://ftp.exim.llorien.org/pcre/

[root@bwebdata]# wget http://ftp.exim.llorien.org/pcre/pcre-8.36.tar.gz --這里因為下載失敗，所以重新去csdn資源庫下載了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安裝也可以：

[root@bwebhttpd-2.4.12]# yum install -y pcre*
**必要的組件安裝完了，我們可以繼續源碼編譯apache了**

2 最后編譯安裝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

啟動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：
在瀏覽器中輸入地址：http://172.16.1.4/，會顯示如下信息：
It works!

apache安裝完畢后ab命令存放在apache安裝目錄的bin目錄下。如下：

[root@bwebhttpd-2.4.12]# ll /usr/local/apache2/bin total 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 20200 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]#

/usr/local/apache2/bin/ab -c 1000 -n 1000 http://127.0.0.1/phpinfo.php

3,ab壓測結果如下：
