Failed to start redis.service: Unit redis-server.service is masked
if redis.service file is missed in directory path /etc/systemd/system/redis.service so we have to create file into this directory using command like:
sudo nano /etc/systemd/system/redis.service and write following things
[Unit]
Description=Redis In-Memory Data Store
After=network.target
[Service]
User=redis
Group=redis
ExecStart=/usr/local/bin/redis-server /etc/redis/redis.conf
ExecStop=/usr/local/bin/redis-cli shutdown
Restart=always
[Install]
WantedBy=multi-user.target
Here
- Unit is description and defining the network behavior,
- Service is to specify the service's behavior and
- Install define the systemd target that the service should attach to if enabled.
Then create redis user group and directories using
sudo adduser --system --group --no-create-home redis
sudo mkdir /var/lib/redis(Create directory)sudo chown redis:redis /var/lib/redis(Change owner permission)sudo chmod 770 /var/lib/redis
run the service sudo systemctl start redis
It will be work fine and check the status using
sudo systemctl status redis
I found the solution. I think it will help for others | systemctl unmask servicename
$ sudo systemctl unmask redis-server.service
1.sudo systemctl unmask redis-server.service
