Installation and Configuration
Installing and setting up Valkey on Ubuntu 22.04 involves a few key steps. This process includes getting the software, adjusting settings, and managing the service.
Installing Valkey from Packages
Valkey can be installed easily on Ubuntu systems. First, create directories for Valkey’s config files and data:
sudo mkdir /etc/valkey
sudo mkdir /var/valkey
Next, download the Valkey package and install it:
wget https://valkey.io/downloads/valkey-latest.deb
sudo dpkg -i valkey-latest.deb
This will place the valkey-server and valkey-cli binaries in /usr/local/bin. Copy the init script from the utils directory to /etc/init.d for proper service management.
Configuring Valkey as an In-Memory Data Store
After installation, configure Valkey by editing its main configuration file:
sudo nano /etc/valkey/valkey.conf
Key settings to adjust:
- Set ‘bind’ to the IP address Valkey should listen on
- Adjust ‘port’ if needed (default is 6379)
- Set ‘maxmemory’ to limit memory usage
- Enable persistence with ‘save’ directives
Save the file and exit the editor when done.
Managing Valkey Operations
To start Valkey, use the systemd service:
sudo systemctl start valkey
Enable Valkey to start on boot:
sudo systemctl enable valkey
Check Valkey’s status:
sudo systemctl status valkey
Connect to Valkey using the command-line interface:
valkey-cli
Use this to test connectivity, run commands, and manage data. Remember to secure Valkey by setting a password in the config file and using the AUTH command when connecting.
