单机部署 elasticsearch

1. install es

Install with Debian package

configuring es

elasticsearch.yaml:

cluster.name: es-test

node.name: es-test-1

path.data: /var/lib/elasticsearch

path.logs: /var/log/elasticsearch

# Lock the memory on startup:
bootstrap.memory_lock: true

network.host: 172.20.133.158

2. Reset user password

Reset the elastic superuser password

/usr/share/elasticsearch/bin/elasticsearch-reset-password -u elastic

Reset kibana password

/usr/share/elasticsearch/bin/elasticsearch-reset-password -u kibana

kibana 使用这个账号密码连接 es, 无法使用 elastic superuser.
