1. elasticsearch新增节点

1.1 第一个节点配置文件如下

cluster.name: joe-es
node.name: node-1
network.host: 192.168.1.160
network.publish_host: 192.168.1.160
http.port: 9200
transport.host: 192.168.1.160
transport.tcp.port: 9300

discovery.zen.minimum_master_nodes: 2
discovery.zen.fd.ping_timeout: 1m
discovery.zen.fd.ping_retries: 5
http.cors.enabled: true
http.cors.allow-origin: "*"
#
##设置主服务
node.master: true
#
node.data: true

discovery.seed_hosts: ["192.168.1.160:9300", "192.168.1.161:9300"]
#cluster.initial_master_nodes: ["192.169.1.160"]
cluster.initial_master_nodes: ["node-1", "node-2"]

1.2 第二个节点配置如下

cluster.name: joe-es
node.name: node-2
network.host: 192.168.1.161
network.publish_host: 192.168.1.161
http.port: 9200
transport.host: 192.168.1.161
transport.tcp.port: 9300

node.master: true
node.data: true

#支持跨域访问
http.cors.enabled: true
http.cors.allow-origin: "*"

discovery.zen.minimum_master_nodes: 2

#discovery.seed_hosts: ["192.168.1.161:9300"]
discovery.seed_hosts: ["192.168.1.160:9300", "192.168.1.161:9300"]
discovery.zen.fd.ping_timeout: 1m
discovery.zen.fd.ping_retries: 5
cluster.initial_master_nodes: ["node-1", "node-2"]

action.destructive_requires_name: true
action.auto_create_index: .security,.monitoring*,.watches,.triggered_watches,.watcher-history*
xpack.security.enabled: false
xpack.monitoring.enabled: true
xpack.graph.enabled: false
xpack.watcher.enabled: false
xpack.ml.enabled: false

1.3 需要注意的关键点

1. 防火墙端口是否开放
2. 如果没有自动加入节点、请检查es目录下data中是否清空 不清空会无法加入
