树莓派上安装Redis的指南（树莓派 安装 redis）

Install Redis on Raspberry Pi

Raspberry Pi is a microcomputer that can be used for many things such as media centers, home automation, data analysis, computer vision and many more. Redis is an open source, in-memory data structure store which can be used to store data as key-value prs. Using Redis on a Raspberry Pi provides an easy and inexpensive way to access a fast database. This guide will expln how to install Redis on a Raspberry Pi.

Before you start, make sure your Raspberry Pi is up to date by running the appropriate command. If you are running a Raspberry Pi OS, the command is:

sudo apt update && sudo apt-get upgrade

Once your Raspberry Pi is up to date, you can install Redis. The first step is to install all necessary libraries accepted by Redis. For this, use the command with Sudo:

sudo apt-get install build-essential tcl

After running this command, all the necessary libraries needed to compile and install Redis will be installed. Now, we need to download and install the latest version of Redis which is currently 4.0.14. To do this, run the command:

wget http://download.redis.io/redis-stable.tar.gz

This will download the Redis setup to your Raspberry Pi. Once the download is complete, extract the setup using the command:

tar xvzf redis-stable.tar.gz

This will create a folder called ‘redis-stable’ in your current directory. Go into this folder by running the command:

cd redis-stable

Now, compile the Redis source code by running the command:

make

Once the compilation is complete, execute the Installation Script using the command:

sudo make install

We have now successfully installed Redis on your Raspberry Pi. The next step is to configure Redis. To do this, start by creating a new configuration file by running the command:

sudo nano /etc/redis/redis.conf

This will open the configuration file in the Nano text editor. Scroll down to the bottom of the file and update the following options:

maxmemory 256mb
maxmemory-policy allkeys-lru

Once you are finished, press Ctr+X and save the file by pressing Y.

After completing these steps, you now have Redis installed and configured on your Raspberry Pi. To start using Redis, use the command:

redis-server &

This will start the Redis server on port 6379. You can now start using Redis on your Raspberry Pi.

In conclusion, Redis is a great tool for Raspberry Pi projects, and the steps above will help you get it installed and configured in no time.
