Error: unit redis.service could not be found.
What's Causing This Error
The error "unit redis.service could not be found" typically occurs when the Redis service is not properly installed or configured on a Linux-based system. When attempting to start the Redis service, the operating system checks for the existence of the Redis service unit file and fails if it is not found.
Solution - Here's How To Resolve It
To resolve this issue, ensure that Redis is installed on your system correctly and that the Redis service unit file exists in the correct location. If Redis is not installed, follow the installation instructions for your specific Linux distribution. Once Redis is installed, restart the Redis service by running the following command:
sudo systemctl restart redis.service
If the error persists after restarting the Redis service, verify that the Redis service unit file exists in the correct location. On most Linux distributions, the Redis service unit file is located in the /etc/systemd/system/ directory. If the Redis service unit file is missing, you can create it manually by creating a new file at /etc/systemd/system/redis.service with the following contents:
[Unit]
Description=Redis In-Memory Data Store
After=network.target
[Service]
User=redis
Group=redis
ExecStart=/usr/bin/redis-server /etc/redis/redis.conf
ExecStop=/usr/bin/redis-cli shutdown
Restart=always
[Install]
WantedBy=multi-user.target
Once the Redis service unit file is created, reload the systemd daemon by running the following command:
sudo systemctl daemon-reload
And then start the Redis service again:
sudo systemctl start redis.service
