How To Install and Configure Redis on Ubuntu 16.04

https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-redis-on-ubuntu-16-04

Introduction

Redis is an in-memory key-value store known for its flexibility, performance, and wide language support. In this guide, we will demonstrate how to install and configure Redis on an Ubuntu 16.04 server.

Prerequisites

To complete this guide, you will need access to an Ubuntu 16.04 server. You will need a non-root user with sudo privileges to perform the administrative functions required for this process. You can learn how to set up an account with these privileges by following our Ubuntu 16.04 initial server setup guide.

When you are ready to begin, log in to your Ubuntu 16.04 server with your sudo user and continue below.

关键是要注意在初始化页面时设置 viewport width=320.1, 非常之诡异!
PS: 在查了N多资料, N多尝试后发现, 其实只要不将width设置成320或device-width即可, 其他任何数字都可以! 不设置width这个属性也可以!
