Проблема
У меня есть работающий кластер, и я хотел бы добавить в него узел данных. Работающий кластер -
x.x.x.246
, а узел данных -
x.x.x.99
. Каждый сервер может видеть друг друга с помощью ping. ОС машины: CentOS7 Elasticsearch: 7,61
конфиги:
здесь --asticsearch.yml из xxx246:
cluster.name: elasticsearch
node.master: true
node.name: Node_master
node.data: true
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
network.host: x.x.x.246
http.port: 9200
discovery.seed_hosts: ["x.x.x.99:9300"]
cluster.initial_master_nodes: ["x.x.x.246:9300"]
здесьasticsearch.yml из xxx99
cluster.name: elasticsearch
node.name: Node_master
node.data: true
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
network.host: x.x.x.99
http.port: 9200
discovery.seed_hosts: ["x.x.x.245:9300"]
cluster.initial_master_nodes: ["x.x.x.246:9300"]
Проверка работоспособности эластичного поиска на машине
Когда я запускаю systemctl start elasticsearch
на каждой машине, она работает хорошо.
тестовый запуск на xxx246
curl -X GET "X.X.X.246:9200/_cluster/health?pretty"
show: номер узла не изменяется
curl -X GET "X.X.X.99:9200/_cluster/health?pretty
show:
{
"error" : {
"root_cause" : [
{
"type" : "master_not_discovered_exception",
"reason" : null
}
],
"type" : "master_not_discovered_exception",
"reason" : null
},
"status" : 503
}
