Caution
You're viewing documentation for a previous version of Scylla Manager. Switch to the latest stable version.
By default Scylla Manager Agent starts API server on port 10001. The following procedure changes the default port.
Note that this procedure needs to be repeated for each Scylla node.
Procedure
Edit the /etc/scylla-manager-agent/scylla-manager-agent.yaml
.
Uncomment and set https_port
to match your desired port - all nodes must use the same port.
Save the file.
Restart Scylla Manager Agent service.
sudo systemctl start scylla-manager-agent
Verify the Scylla Manager Agent is running.
sudo systemctl status scylla-manager-agent -l
● scylla-manager-agent.service - Scylla Manager Agent
Loaded: loaded (/usr/lib/systemd/system/scylla-manager-agent.service; disabled; vendor preset: disabled)
Active: active (running) since Wed 2019-10-30 10:46:51 UTC; 7s ago
Main PID: 14670 (scylla-manager-)
CGroup: /system.slice/scylla-manager-agent.service
└─14670 /usr/bin/scylla-manager-agent
After that Change cluster port in Scylla Manager.
sctool cluster update -c <your cluster> --port <new port>
You can also pass the --port
flag to sctool cluster add command when registering a new cluster.
Although Scylla Manager is aware of all topology changes made within every cluster it manages, it cannot properly manage a cluster without establishing connections with every node in the cluster using the Scylla Manager Agent which is on each managed node.
Procedure
Add Scylla Manager Agent to the new node. Use the same authentication token as you did for the other nodes in this cluster. Do not generate a new token.
Confirm the node / datacenter was added by checking its sctool status. From the node running Scylla Manager server run the sctool status
command, using the name of the managed cluster.
sctool status -c prod-cluster
Datacenter: eu-west
