Windows下安装Elasticsearch

• 官网下载：https://www.elastic.co/downloads/elasticsearch ， elasticsearch-7.8.0-no-jdk-windows-x86_64.zip，要求已经配置JAVA_HOME环境变量

• 单节点安装：解压后直接运行.bat启动，http://localhost:9200/ 访问正常即可

• 多节点安装：如果配置为都可以为master，半数以上可用？

# ======================== 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
cluster.name: my-application # 集群名称 各节点配置的要相同
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
#node.name: node-1
node.name: node-1002
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
node.master: true # 是否允许为主节点
node.data: true # 是否存储数据
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
#path.data: /path/to/data
#
# Path to log files:
#
#path.logs: /path/to/logs
#
# ----------------------------------- 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 -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
#network.host: 192.168.0.1
network.host: localhost # 节点绑定的ip地址
#
# Set a custom port for HTTP:
#
#http.port: 9200
http.port: 1002 # 节点对外提供的http端口
transport.tcp.port: 9302 # 内部tcp端口
#
# 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: ["host1", "host2"]
discovery.seed_hosts: ["localhost:9301","localhost:9302", localhost:9303] # 可以发现的其他节点主机
discovery.zen.fd.ping_timeout: 1m # 节点之间的超时时间
discovery.zen.fd.ping_retries: 5 # 节点之间尝试次数

#
# Bootstrap the cluster using an initial set of master-eligible nodes:
#
#cluster.initial_master_nodes: ["node-1", "node-2"]
#cluster.initial_master_nodes: ["node-1001", "node-1002"] # 可以被选为主节点的节点列表
#
# For more information, consult the discovery and cluster formation module documentation.
#
# ---------------------------------- Gateway -----------------------------------
#
# Block initial recovery after a full cluster restart until N nodes are started:
#
#gateway.recover_after_nodes: 3
#
# For more information, consult the gateway module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Require explicit names when deleting indices:
#
#action.destructive_requires_name: true
# 跨域配置
http.cors.enabled: true
http.cors.allow-origin: "*" 

Linux下安装Elasticsearch

• 单机安装

  添加es单独的用户，es不允许使用root直接运行

  useradd es
  passwd es # 设置密码
  userdel -r es # 该命令可用删除用户
  chown -R es:es /opt/module/es # 将es的目录下的所有文件都修改为es用户和es用户组

  配置文件修改参考上述配置文件

  修改/es/security/limits.conf 每个进程可以打开的文件数限制 增加下面配置

  es soft nofile 65536
  es hard nofile 65536

  • hard nproc 4096 # 操作系统级别对每个用户创建的进程的限制 *表示所有用户

  修改/etc/sysctl.conf 一个进程可用拥有的虚拟内存的大小，默认65536

  vm.max_map_count=655360

  修改后重新加载配置

  sysctl -p

  启动es

  bin/elasticsearch # 或者bin/elasticsearch -d后台启动，如果启动时显示文件与所属用户不匹配，需要再执行下chown -R es:es /opt/module/es

• 集群下安装其他配置：

docker下安装Elasticsearch

下载镜像文件
docker pull elasticsearch:7.4.2     # 存储和检索数据
docker pull kibana:7.4.1            # 可视化检索数据

创建实例
mkdir -p /mydata/elasticsearch/config
mkdir -p /mydata/elasticsearch/data
echo "http.host:0.0.0.0">>/mydata/elasticsearch/config/elasticsearch.yml # 保证所有外部都可以访问

docker run --name elasticsearch -p 9200:9200 -p 9300:9300 \
-e "discovery.type=single-node" \
-e ES_JAVA_OPTS="-Xms128m -Xmx256m" \
-v /mydata/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml \
-v /mydata/elasticsearch/data:/usr/share/elasticsearch/data \
-v /mydata/elasticsearch/plugins:/usr/share/elasticsearch/plugins -d elasticsearch:7.6.2
# 访问端口和内部通信端口
# 单节点
# JVM的配置，不配置会尽可能的占用内存
# 将外部挂载文件和默认路径关联，保持同步

# 注意外部文件夹的权限
# 安装完成后可以访问9200端口

# 其他命令
docker ps
docker images
## 安装Kibana
docker run --name kibana -e ELASTICSEARCH_HOSTS=http://虚拟机地址:9200 -p5601:5601 -d kibana:7.4.1

## 安装完成后可以在5601端口访问

## 或者使用postman个ES发送请求

Kibana安装

需要修改配置：

server.port: 5601
server.host: "127.0.0.1"
# 配置es集群url
elasticsearch.hosts: ["http://127.0.0.1:9200/"]
kibana.index: ".kibana"

chrome ElasticSearch-head插件安装

在谷歌浏览器扩展程序添加解压后的插件即可
