Setup Remote Redis Server on Linux VPS

Redis is a flexible, high-performance database engine that supports complex operations and use-cases. You can set up a Redis server to run on your VPS and accept remote commands to modify, read, and perform operations on the database.

Step 1: Install the Redis backend.

RHEL / CentOS / Amazon Linux

sudo yum install Redis 

Ubuntu / Debian

sudo apt-get install Redis-server 

Fedora

sudo dnf -y install Redis.

Step 2: Start the Redis server backend service.

RHEL / CentOS / Amazon, Linux

sudo systemctl, start Redis 

Ubuntu / Debian

sudo systemctl start Redis-server. service 

Fedora

sudo systemctl start Redis

Step 3: Verify the Redis server is running

ps -aux | grep redis

You can also verify the server is handling requests by starting the Redis-cli and issuing the ping command.

redis-cli 127.0.0.1:6379> ping

Step 4: Get public IPv4 address using ifconfig

ifconfig -a

Step 5: Bind the Redis server to your IPv4 address.

sudo vi /etc/redis.conf

By default, the Redis server will be bound to 127.0.0.1, which is only accessible from the server itself. To make the Redis server publicly accessible, you must bind the server to listen to the network interface associated with your public IPv4.

On line 66, modify bind 127.0.0.1 and replace the IP with your VPS IPv4.

Step 6: Restart Redis

RHEL / CentOS / Amazon Linux

sudo systemctl restart redis 

Ubuntu / Debian

sudo systemctl restart Redis. service 

Fedora

sudo systemctl restart Redis

Step 7: Verify external host access.

Verify the server can be accessed from an external host. Using the Redis-cli command on your local machine, you can provide the -h argument to connect to the remote Redis server that was just set up on your VPS.

redis-cli -h 104.168.165.99 104.168.165.99:6379> ping PONG

You are now able to access your Redis node on your VPS remotely.
