02 es 集群搭建

Posted 2022-08-07 蓝风9

前言

呵呵 最近有一系列环境搭建的相关需求

记录一下

es 三个节点 : 192.168.110.150, 192.168.110.151, 192.168.110.152

150 为 master, 151 为 slave01, 152 为 slave02

三台机器都做了 trusted shell  
 

es 单节点 docker 搭建

创建 docker-compose.yml 如下, 然后 docker-compose up -d 启动 es 即可使用

version: '3'
services:
  es:
    image: elasticsearch:7.7.0
    container_name: es
    environment:
      - "cluster.name=es"
      - "discovery.type=single-node"
      - "ES_JAVA_OPTS=-Xms1024m -Xmx1024m"
    volumes:
#      - ./es/plugins:/usr/share/elasticsearch/plugins
      - ./es/data:/usr/share/elasticsearch/data
      - ./es/config:/usr/share/elasticsearch/config
    ports:
      - 9200:9200
      - 9300:9300
  kibana:
    image: kibana:7.7.0
    container_name: kibana
    depends_on:
      - es
    environment:
      - "elasticsearch.hosts=http://es:9200"
    volumes:
      - ./kibana/config:/usr/share/kibana/config
    ports:
      - 5601:5601

es 集群搭建

es 三个节点 : 192.168.110.150, 192.168.110.151, 192.168.110.152

1. 基础环境准备 

192.168.110.150, 192.168.110.151, 192.168.110.152 上面安装 jdk, 上传 es 的安装包 

es 7.17 至少需要 jdk11

安装包来自于 Download Elasticsearch | Elastic

2. es 配置调整 

更新 master, slave01, slave02 的 elasticsearch.yml 的配置文件如下 

cluster.name: es_cluster
cluster.initial_master_nodes: ["master_1"]
node.master: true
node.max_local_storage_nodes: 3
node.name: master_1
node.data: false
path.data: /data/es/data/master_1
path.logs: /data/es/log/master_1
bootstrap.memory_lock: true
network.host: master
http.port: 9210
transport.tcp.port: 9310
discovery.zen.ping.unicast.hosts: ["master:9310"]
discovery.zen.minimum_master_nodes: 1
gateway.recover_after_nodes: 1
action.destructive_requires_name: true
discovery.zen.ping_timeout: 10s
node.attr.size: medium

cluster.name: es_cluster
cluster.initial_master_nodes: ["master_1"]
node.master: false
node.max_local_storage_nodes: 3
node.name: slave_1
node.data: true
path.data: /data/es/data/slave_1
path.logs: /data/es/log/slave_1
bootstrap.memory_lock: true
network.host: slave01
http.port: 9210
transport.tcp.port: 9310
discovery.zen.ping.unicast.hosts: ["master:9310"]
discovery.zen.minimum_master_nodes: 1
gateway.recover_after_nodes: 1
action.destructive_requires_name: true
discovery.zen.ping_timeout: 10s
node.attr.size: medium

cluster.name: es_cluster
cluster.initial_master_nodes: ["master_1"]
node.master: false
node.max_local_storage_nodes: 3
node.name: slave_2
node.data: true
path.data: /data/es/data/slave_2
path.logs: /data/es/log/slave_2
bootstrap.memory_lock: true
network.host: slave02
http.port: 9210
transport.tcp.port: 9310
discovery.zen.ping.unicast.hosts: ["master:9310"]
discovery.zen.minimum_master_nodes: 1
gateway.recover_after_nodes: 1
action.destructive_requires_name: true
discovery.zen.ping_timeout: 10s
node.attr.size: medium

三台机器分别创建 数据目录, 日志目录 

mkdir -p /data/es/data/master_1
mkdir -p /data/es/log/master_1

mkdir -p /data/es/data/slave_1
mkdir -p /data/es/log/slave_1

mkdir -p /data/es/data/slave_2
mkdir -p /data/es/log/slave_2

新增 es 用户, 并增加相关配置 

groupadd es
useradd -g es es
chown -R es:es /usr/local/ProgramFiles/elasticsearch-7.17/
chown -R es:es /data/es
passwd es

3. 修改涉及的系统配置

编辑 /etc/security/limits.conf, 新增如下配置 

* soft nofile 300000
* hard nofile 300000
* soft nofile 65536
* hard nofile 65536
* hard memlock unlimited
* soft memlock unlimited

编辑 /etc/sysctl.conf 配置文件, 新增如下配置, 并使用 sysctl -p 重启 

vm.max_map_count=262144
vm.swappiness=1

4. 切换到 es 用户, 启动集群 

三台机器 分别切换到 es 用户 

并启动集群, 注意 es 7.17 需要 jdk11 

./bin/elasticsearch -d 

测试集群

基于 curl 的测试
