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

deployment Architecture

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

../_images/syncer-deploy-architecture.png

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

../_images/app-conf.png

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

../_images/instance-az.png

chassis.yaml: modify listenAddress to the local ip address

../_images/chassis.png

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.
