PageSpeed是Vultr服务器Nginx里的一个组件，不过是默认不安装的。PageSpeed在一定范围内可以提高项目的访问速度，可以重写网页，提高用户的访问速度，比如压缩图片大小、缩减CSS和JavaScript文件，从而来提高存储的效率。本文小编就教大家怎样在Vultr VPS基于Debian 8安装PageSpeed。
1.升级和安装软件
apt-get update -y
apt-get dist-upgrade -y
apt install build-essential ca-certificates zlib1g-dev libpcre3 libpcre3-dev tar unzip libssl-dev
2.下载ngx_pagespeed组件
cd /opt
wget https://github.com/pagespeed/ngx_pagespeed/archive/v${NPS_VER}-beta.zip
unzip v${NPS_VER}-beta.zip
rm v${NPS_VER}-beta.zip
cd ngx_pagespeed-${NPS_VER}-beta
psol_url=https://dl.google.com/dl/page-speed/psol/${NPS_VERSION}.tar.gz
[ -e scripts/format_binary_url.sh ] && psol_url=$(scripts/format_binary_url.sh PSOL_BINARY_URL)wget ${psol_url}
tar -xzvf $(basename ${psol_url})
rm ${NPS_VER}-x64.tar.gz
3.编译和安装Nginx
cd /opt
wget -qO- http://nginx.org/download/nginx-${NGINX_VER}.tar.gz | tar zxf –
配置模块参数，包括Nginx PageSpeed模块。
cd nginx-${NGINX_VER}
./configure \
–prefix=/etc/nginx \
–sbin-path=/usr/sbin/nginx \
–conf-path=/etc/nginx/nginx.conf \
–error-log-path=/var/log/nginx/error.log \
–http-log-path=/var/log/nginx/access.log \
–pid-path=/var/run/nginx.pid \
–lock-path=/var/run/nginx.lock \
–http-client-body-temp-path=/var/cache/nginx/client_temp \
–http-proxy-temp-path=/var/cache/nginx/proxy_temp \
–http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp \
–user=nginx \
–group=nginx \
–without-http_ssi_module \
–without-http_scgi_module \
–without-http_uwsgi_module \
–without-http_geo_module \
–without-http_map_module \
–without-http_split_clients_module \
–without-http_memcached_module \
–without-http_empty_gif_module \
–without-http_browser_module \
–with-threads \
–with-file-aio \
–with-http_ssl_module \
–with-http_v2_module \
–with-ipv6 \
–with-http_mp4_module \
–with-http_auth_request_module \
–with-http_slice_module \
–add-module=/opt/ngx_pagespeed-release-${NPS_VER}-beta
编译：
make -j $(nproc)
安装：
make install
最后，我们可以验证ngx_pagespeed模块是否安装到NGINX。
