在linux系统上源码安装nginx前的准备

yum -y install gcc //sudo apt-get install g++ sudo apt-get install gcc
yum install pcre-devel
yum install zlib-devel

sudo apt-get install libpcre3 libpcre3-dev
sudo apt-get install zlib1g
sudo apt-get install zlib1g.dev

安装nginx之前应先安装gcc g++、 build-essential、pcre-8.37和 zlib-1.2.8
pcre-8.37 安装前 先安装：gcc g++

yum install build-essential

执行安装命令时出现的问题：Package build-essential is not available
解决办法：[sudo apt-get update && sudo aptitude install build-essential]
CentOS 和RedHat： yum install build-essential
ubuntu ：apt-get install build-essential
3、pcre
