安装elasticsearch7.8

1. 下载elasticsearch7.8

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.8.0-linux-x86_64.tar.gz

3. 安装
   准备：

• 创建elasticsearch 数据文件目录和日志文件目录

mkdir -p /data/elastic-data/data
mkdir -p /data/elastic-data/logs

解压即安装

cd /opt
tar -xvf elasticsearch-7.8.0-linux-x86_64.tar.gz
cd elasticsearch-7.8.0

4. 配置

• 修改 config/elasticsearch.yml
• yml

#默认只能本机请求，0.0.0.0 是指监听所有ip的连接
network.host: 0.0.0.0
#开启memory_lock 需修改系统配置（/etc/security/limits.conf）并重启系统
#bootstrap.memory_lock: true
#端口号使用默认端口
http.port: 9200
cluster.name: ES_Cluster
node.name: node-s01-1
path.data: /data/elastic-data/data
path.logs: /data/elastic-data/logs
discovery.seed_hosts: ["172.16.1.126", "172.16.1.128","172.16.1.129","172.16.1.130"]
cluster.initial_master_nodes: ["172.16.1.126","172.16.1.1
28"]
gateway.recover_after_nodes: 3

• 修改系统配置-limit数量 (开启memory_lock时才需要)

vim /etc/security/limits.conf  #添加以下内容（需要重新登陆系统生效）
* soft nofile 75535
* hard nofile 75535

• 修改内核参数vm.max_map_count(开启memory_lock时才需要)

vim /etc/sysctl.conf  #添加以下内容
vm.max_map_count=262144
#执行以下命令生效
sysctl -p

4. 启动

./bin/elasticsearch -d -p pid  #-d 指后台运行

5. 验证是否启动成功：

[release@izbp195wx elasticsearch-7.8.0]$ curl http://172.16.1.128:9200
{
  "name" : "node-s02-2",
  "cluster_name" : "ES_Cluster",
  "cluster_uuid" : "r4AQsaRiSSm6WAOZDKNd_Q",
  "version" : {
    "number" : "7.8.0",
    "build_flavor" : "default",
    "build_type" : "tar",
    "build_hash" : "757314695644ea9a1dc2fecd26d1a43856725e65",
    "build_date" : "2020-06-14T19:35:50.234439Z",
    "build_snapshot" : false,
    "lucene_version" : "8.5.1",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}
