How to Install Redis® on FreeBSD 14.0
Introduction
Redis® is an in-memory NoSQL database used as a key-value store, document database, or vector database. It supports fast read and write operations with common data structures such as Strings, Hash, List, Set, Stream, and Bitmap. Redis® is a versatile data store used with different types of storage applications such as caching, streaming, and messaging.
This article explains how to install Redis® on a FreeBSD 14.0 server.
Prerequisites
Before you begin:
- Deploy a FreeBSD 14 instance on Vultr.
- Access the server using SSH as a non-root user with sudo privileges.
Install Redis®
Redis® is available in the default package repositories on FreeBSD 14.0. Follow the steps below to install the latest available package on your server.
Update the server's package index.
CONSOLESearch for all available Redis® packages.
CONSOLEOutput:
Install the latest available package. For example,
Redis® 7.2.5.CONSOLEEnable the Redis® service to automatically start at system boot.
CONSOLEStart the Redis® service on your server.
CONSOLEOutput:
View the Redis® system service status and verify that it's running.
CONSOLEOutput:
Configure Redis®
Redis® uses the /usr/local/etc/redis.conf file to run on your server with specific configurations. Follow the steps below to modify the configuration file and enable Redis® to listen for incoming connection requests.
Open the Redis® configuration file
/usr/local/etc/redis.confusing a text editor such asvi.CONSOLESet the
timeoutconfiguration directive to close the connection when a client is idle.INISet the
daemonzedirective toyesto run Redis® as a daemon.INISet the server's verbosity level.
INISet the maximum number of databases to run on the server. By default
16.INISet the
saveconfiguration directive to periodically take a snapshot of available databases to disk.INISet the maximum number of clients that can connect at the same time.
INISet the maximum memory usage limit.
INIEnable threading when using a multi-core server.
INIEnable the Append Only File (AOF) option as an alternative persistence mode to avoid database write failures.
INIEnable the Redis® instance as a cluster node.
INILog queries that exceed the specified execution time (microseconds).
INISave and close the configuration file.
Restart the Redis® service to apply the configuration changes.
CONSOLEOutput:
Secure Redis®
Follow the steps below to secure Redis®.
Open the main configuration file
/usr/local/etc/redis.conf.CONSOLEEnable protected mode to allow only local connection requests and require password authentication for all users.
INISet the default user password.
INIBind Redis® to a specific network address on your server such as
127.0.0.1.INISet the following configuration directive to block insecure commands.
INIRemove sensitive privileges from regular user accounts.
INISave and close the configuration file.
Restart Redis® to apply the configuration changes.
CONSOLE
Access Redis®
Follow the steps below to test access to the Redis® shell.
Access the Redis® CLI.
CONSOLEAuthenticate the
defaultuser using the password you set earlier.CONSOLEOutput:
Send a
PINGrequest to the server and verify that it's accepted.CONSOLEOutput:
Select a database such as
1CONSOLEOutput:
View all secure database user profiles.
CONSOLEOutput:
Create a new key in the database with the value
Greetings from Vultr.CONSOLEOutput:
View the key value.
CONSOLEOutput:
Exit the Redis CLI.
CONSOLE
Conclusion
You have installed Redis® on FreeBSD 14.0 and secured the server to enable authentication for all database users. You can integrate Redis® databases with dynamic applications to enable caching and improve your server performance. For more information, visit the Redis® documentation.
