Install Redis 7 on Amazon EC2 Linux

Redis is an in-memory data store that can be used for a variety of purposes, including caching, messaging, and leaderboards.

Steps to install

1. Connect to your EC2 instance
2. Install gcc

gcc, or the GNU Compiler Collection, is a set of compiler programs that we’ll need to compile Redis from source. To install gcc, run the following command on your EC2 instance:

sudo yum install gcc

Enter ‘y’ at the confirmation prompt.

3. Download and build redis-server

Redis is typically installed by compiling the source code. We’ll download the latest stable version of Redis from the official website and then compile it.

First, use wget to download the compressed tar archive of the Redis source code:

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

Next, extract the contents of the archive using tar:

tar xvzf redis-stable.tar.gz

This will create a directory called redis-stable. Navigate into this directory:

cd redis-stable

Finally, compile the Redis source code using make:

make

This will build the Redis server executable.

4. Create a Default Configuration File

Redis provides a sample configuration file (redis.conf) in the source directory. You can copy and use it as the default

sudo mkdir -p /etc/redis 
sudo cp redis-stable/redis.conf /etc/redis/6379.conf

5. Update the Configuration File

Edit the copied configuration file as needed.

sudo nano /etc/redis/6379.conf

Set Redis to run as a daemon:

daemonize yes

6. Setup Redis as a service

• Copy the redis-server binary to /usr/local/bin:

sudo cp src/redis-server /usr/local/bin/ 
sudo cp src/redis-cli /usr/local/bin/

• Use an init script or systemd service. Redis provides a sample init script in the utils folder:

sudo cp utils/redis_init_script /etc/init.d/redis 
sudo chmod +x /etc/init.d/redis 
sudo update-rc.d redis defaults

7. Start redis

sudo service redis start
