Required of third party softwares

• JDK 6+（instruments application can run in jdk6）
• JDK8 ( skywalking collector and skywalking webui )
• Elasticsearch 5.2.2 or 5.3, cluster mode or not
• Zookeeper 3.4.10

Download released version

Deploy Elasticsearch server

• Modify elasticsearch.yml
  • Set cluster.name: CollectorDBCluster
  • Set node.name: anyname, this name can be any, it based on Elasticsearch.
  • Add the following configurations to

# The ip used for listening
network.host: 0.0.0.0
thread_pool.bulk.queue_size: 1000

• Start Elasticsearch

Deploy collector servers

1. Run tar -xvf skywalking-collector.tar.gz
2. Config collector in cluster mode.

Cluster mode depends on Zookeeper register and application discovery capabilities. So, you just need to adjust the IP config items in config/application.yml. Change IP and port configs of agent_server, agent_stream, ui, collector_inside, replace them to the real ip or hostname which you want to use for cluster.

• config/application.yml

cluster:
# The Zookeeper cluster for collector cluster management.
  zookeeper:
    hostPort: localhost:2181
    sessionTimeout: 100000
