服务器评测在上一篇文章里我们学习了如何安装ICC编译器，今天我们来记录一下用icc编译一台web服务器的过程。但是比较遗憾的是，根据我的测试，同样的参数，用icc编译出来的环境，运行discuz并未比用gcc编译出来的环境要有多大的提升，这是比较令人沮丧的。当然，也许是编译参数未能调整到最优的缘故。不管怎样，还是把这个编译过程记录下来吧，留作参考。

1、准备工作
前提是你的服务器已经安装了icc编译器，没安装的话移步这里：http://www.linuxidc.com/Linux/2012-12/76637.htm
下载相关的源码：
wget http://cn.php.net/get/php-5.4.8.tar.gz/from/this/mirror
wget http://www.percona.com/redir/downloads/Percona-Server-5.5/LATEST/source/Percona-Server-5.5.27-rel29.0.tar.gz
wget http://tengine.taobao.org/download/tengine-1.4.1.tar.gz
wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz
wget https://github.com/downloads/libevent/libevent/libevent-2.0.20-stable.tar.gz
wget “http://downloads.sourceforge.net/mcrypt/libmcrypt-2.5.8.tar.gz?modtime=1171868460&big_mirror=0”
wget “http://downloads.sourceforge.net/mcrypt/mcrypt-2.6.8.tar.gz?modtime=1194463373&big_mirror=0”
wget http://download.savannah.gnu.org/releases/libunwind/libunwind-1.1.tar.gz
wget https://gperftools.googlecode.com/files/gperftools-2.0.tar.gz
wget http://downloads.sourceforge.net/project/pcre/pcre/8.31/pcre-8.31.tar.gz
其他还有memcache、imagick等大家就根据实际需要来下载安装吧。为了节约篇幅我们今天就不涉及这些东东了。
设置动态链接库的路径，避免后续编译的时候出错：
vi /etc/ld.so.conf
最后增加：
/opt/intel/lib/intel64/
/usr/local/lib
/usr/lib
保存
vi /etc/ld.so.conf.d/usr_local_lib.conf
/usr/local/lib
/usr/lib
保存
ldconfig
2、编译安装

特别说明：用icc编译tengine的时候，with-pcre后面如果跟上pcre的路径，就会报错，这跟gcc编译正好相反。。。
