Syncer

Service-Center supports synchronization. If you want to use synchronization, you can refer to the step.

preparation before installation

download package

Note: Only the 2.1+ version of sc supports synchronization

• service-center
• etcd

deployment Architecture

As shown in the figure below, etcd can be deployed as an independent cluster.

It can also be deployed like this.

installation operation

install etcd

Refer to the official website documentation.

install sc

Note: Only the 2.1+ version of sc supports synchronization

step 1

modify the files in conf

app.conf: modify frontend_host_ip and httpaddr to the local ip address

app.yaml:

modify

1. server.host
2. REGISTRY_KIND
3. REGISTRY_ETCD_CLUSTER_NAME
4. REGISTRY_ETCD_CLUSTER_MANAGER_ENDPOINTS
5. REGISTRY_ETCD_CLUSTER_ENDPOINTS
6. registry.instance.datacenter.name
7. registry.instance.datacenter.region
8. registry.instance.datacenter.availableZone

chassis.yaml: modify listenAddress to the local ip address

syncer.yaml: turn on the enableOnStart switch, and modify endpoints, the sc machine ip in region-2

step 2

Repeat the above operation to modify the configuration of sc on other machines.

step 3

sh start-service-center.sh

step 4

sh start-frontend.sh

step 5

Open the front-end interface of any node.

Instances in the peer region have been synchronized.

verify health

curl -k http://{ip}:30100/health
