如何安装？

安装编译所需类库

下载nginx源码

wget http://nginx.org/download/nginx-1.6.3.tar.gz

解压

tar zxvf nginx-1.6.3.tar.gz

配置编译模块

cd nginx-1.6.3
./configure --prefix=/opt/nginx-1.6.3 --with-pcre \
--with-http_stub_status_module --with-http_ssl_module \
--with-http_gzip_static_module --with-http_realip_module

如果需要用到其他模块，自行根据所需添加即可
