nginx入门

nginx特点

占用cpu/内存资源少，相对apache并发处理能力强

nginx安装

yum -y install gcc zlib zlib-devel pcre-devel openssl openssl-devel

安装pcre? nginx要在rewrite时要解析正则表达式,PCRE是正则解析库

//下载tar包

wget http://nginx.org/download/nginx-1.13.7.tar.gz

tar -xvf nginx-1.13.7.tar.gz

抹去nginx的版本，该步非必需

[ nginx-1.13.7]# cat src/core/nginx.h
