首先需要安装jdk17+
官网介绍：https://www.elastic.co/guide/en/elasticsearch/reference/8.6/deb.html#install-deb
1、安装签名key
#安装Download and install the public signing key:
wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo gpg --dearmor -o /usr/share/keyrings/elasticsearch-keyring.gpg
2、Installing from the APT repository
sudo apt-get install apt-transport-https
3、Save the repository definition to /etc/apt/sources.list.d/elastic-8.x.list:
echo "deb [signed-by=/usr/share/keyrings/elasticsearch-keyring.gpg] https://artifacts.elastic.co/packages/8.x/apt stable main" | sudo tee /etc/apt/sources.list.d/elastic-8.x.list
4、安装当前版本，可能对本地jdk有要求
sudo apt-get update && sudo apt-get install elasticsearch
5、安装8.6版本
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.6.2-amd64.deb wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.6.2-amd64.deb.sha512 shasum -a 512 -c elasticsearch-8.6.2-amd64.deb.sha512 sudo dpkg -i elasticsearch-8.6.2-amd64.deb
6、卸载软件
apt-get remove --purge elasticsearch
7、es 配置文件修改
# ======================== Elasticsearch Configuration ========================= # # NOTE: Elasticsearch comes with reasonable defaults for most settings. # Before you set out to tweak and tune the configuration, make sure you # understand what are you trying to accomplish and the consequences. # # The primary way of configuring a node is via this file. This template lists # the most important settings you may want to configure for a production cluster. # # Please consult the documentation for further information on configuration options: # https://www.elastic.co/guide/en/elasticsearch/reference/index.html # # ---------------------------------- Cluster ----------------------------------- # # Use a descriptive name for your cluster: # cluster.name: my-application # # ------------------------------------ Node ------------------------------------ # # Use a descriptive name for the node: # node.name: node-1 # # Add custom attributes to the node: # #node.attr.rack: r1 # # ----------------------------------- Paths ------------------------------------ # # Path to directory where to store the data (separate multiple locations by comma): # path.data: /data1/elasticsearch4/data # # Path to log files: # path.logs: /data1/elasticsearch4/lo # # ----------------------------------- Memory ----------------------------------- # # Lock the memory on startup: # #bootstrap.memory_lock: true # # Make sure that the heap size is set to about half the memory available # on the system and that the owner of the process is allowed to use this # limit. # # Elasticsearch performs poorly when the system is swapping the memory. # # ---------------------------------- Network ----------------------------------- # # By default Elasticsearch is only accessible on localhost. Set a different # address here to expose this node on the network: # # network.host: 192.168.0.1 # # By default Elasticsearch listens for HTTP traffic on the first free port it # finds starting at 9200. Set a specific HTTP port here: # #http.port: 9200 # # For more information, consult the network module documentation. # # --------------------------------- Discovery ---------------------------------- # # Pass an initial list of hosts to perform discovery when this node is started: # The default list of hosts is ["127.0.0.1", "[::1]"] # discovery.seed_hosts: ["127.0.0.1", "[::1]"] # # Bootstrap the cluster using an initial set of master-eligible nodes: # cluster.initial_master_nodes: ["node-1"] # # For more information, consult the discovery and cluster formation module documentation. # # --------------------------------- Readiness ---------------------------------- # # Enable an unauthenticated TCP readiness endpoint on localhost # #readiness.port: 9399 # # ---------------------------------- Various ----------------------------------- # # Allow wildcard deletion of indices: # #action.destructive_requires_name: false #----------------------- BEGIN SECURITY AUTO CONFIGURATION ----------------------- # # The following settings, TLS certificates, and keys have been automatically # generated to configure Elasticsearch security features on 20-09-2023 02:10:29 # # -------------------------------------------------------------------------------- # Enable security features xpack.security.enabled: false xpack.security.enrollment.enabled: true # Enable encryption for HTTP API client connections, such as Kibana, Logstash, and Agents xpack.security.http.ssl: enabled: false keystore.path: certs/http.p12 # Enable encryption and mutual authentication between cluster nodes xpack.security.transport.ssl: enabled: true verification_mode: certificate keystore.path: certs/transport.p12 truststore.path: certs/transport.p12 # Create a new cluster with the current node only # Additional nodes can still join the cluster later # cluster.initial_master_nodes: ["iZ8vb9rhnolqa4cbx4xnkjZ"] # Allow HTTP API connections from anywhere # Connections are encrypted and require user authentication http.host: 0.0.0.0 # Allow other nodes to join the cluster from anywhere # Connections are encrypted and mutually authenticated #transport.host: 0.0.0.0 #----------------------- END SECURITY AUTO CONFIGURATION -------------------------
