PageSpeed Module for Nginx 配置記憶體快取

ngx_pagespeed 能讓網頁加速，但預設的目錄讀取很慢

如果還沒有安裝 module，請前往上一步配置 LNMP 安裝 ngx_pagespeed module

所以需要使用 tmpfs 記憶體快取

Linux 系統下有一個 /dev/shm 是由 tmpfs 掛載的

建立快取目錄，並賦予所有者

mkdir /dev/shm/ngx_pagespeed_cache
chown www:www /dev/shm/ngx_pagespeed_cache

nginx.conf 添加 pagespeed.conf 配置鏈結

server
{
include pagespeed.conf;

建立 pagespeed.conf 配置文件

vi pagespeed.conf

添加 ngx_pagespeed 配置，此配置僅適用 Discuz!
