Installing Redis on Ubuntu

redis.sh

#Start by updating the apt packages list by running the following command in your SSH terminal:
sudo apt update
#Install Redis by typing:
sudo apt install redis-server
#Once the installation is completed, the Redis service will start automatically. To check the status of the service, enter the following command:
sudo systemctl status redis-server

#Congratulations, at this point you have Redis installed and running on your Ubuntu 18.04 server.


#Configure Redis Remote Access
#By default, Redis doesn't allow remote connections. You can connect to the Redis server only from 127.0.0.1 (localhost) - the machine where Redis is running.

#Perform the following steps only if you want to connect to your Redis server from remote hosts. If you are using a single server setup, where the application and Redis are running on the same machine then you should not enable remote access.
#To configure Redis to accept remote connections open the Redis configuration file with your text editor:

sudo nano /etc/redis/redis.conf
#Locate the line that begins with bind 127.0.0.1 ::1 and replace 127.0.0.1 with 0.0.0.0.


# IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE INTERFACES
# JUST COMMENT THE FOLLOWING LINE.
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
bind 0.0.0.0 ::1
#Save the file and close the editor.Restart the Redis service for changes to take effect:sudo ufw allow proto tcp from 192.168.121.0/24 to any port 6379

sudo systemctl restart redis-server
#Use the following command to verify that redis is listening on all interfaces on port 6379:
ss -an | grep 6379

#Next, you'll need to add a firewall rule that enables traffic from your remote machines on TCP port 6379.

#Assuming you are using UFW to manage your firewall and you want to allow access from the 192.168.121.0/24 subnet you would run the following command:
sudo ufw allow proto tcp from 192.168.121.0/24 to any port 6379


#At this point, Redis server will accept remote connections on TCP port 6379.
#Make sure your firewall is configured to accept connections only from trusted IP ranges.

#To verify that everything is set up properly, you can try to ping the Redis server from your remote machine using the redis-cli utility:
redis-cli -h localhost ping
#The command should return a response of PONG:
