安装Nginx

yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers



1、安装Nginx所需的pcre库：
tar zxvf pcre-7.9.tar.gz
cd pcre-7.9/
./configure
make && make install
cd ../


2、安装Nginx
wget http://labs.frickle.com/files/ngx_cache_purge-1.0.tar.gz
tar zxvf ngx_cache_purge-1.0.tar.gz     （第三方可以指定清除缓存的模块）

tar zxvf nginx-1.0.5.tar.gz
cd nginx-1.0.5/
./configure --user=nginx --group=nginx --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --add-module=../ngx_cache_purge-1.0
make && make install
cd ../
