ElasticSearch安装

1、解压elasticSearch安装包：

tar xzvf elasticsearch-7.8.0-linux-x86_64.tar.gz

2、创建es数据存储目录和日志存放目录

mkdir -p /app/es/data
mkdir -p /app/es/logs

3、修改系统进程内存限制

vim /etc/security/limits.conf
添加以下内容：
* soft nofile 65536
* hard nofile 131072
* soft nproc 2048
* hard nproc 4096

vim /etc/sysctl.conf
添加以下内容：
vm.max_map_count = 262145

执行刷新命令：sysctl -p

4、创建用户

groupadd elsearch
useradd elsearch -g elsearch
passwd elsearch
chown -R elsearch:elsearch /app/elasticsearch-7.8.0
chown -R elsearch:elsearch /app/es/data
chown -R elsearch:elsearch /app/es/logs

5、修改es配置文件

cd /app/elasticsearch-7.8.0/config
vim /elasticsearch.yml

修改一下内容：
node.name: node-1
path.data: /app/es/data
path.logs: /app/es/logs
network.host: 0.0.0.0
http.port: 9200
discovery.seed_hosts: ["127.0.0.1"]
cluster.initial_master_nodes: ["node-1"]

6、启动es

su elsearch
cd /app/elasticsearch-7.8.0/bin
./elasticsearch

7、停止es

ps -ef | grep elastic
kill -9 xxx

8、访问es

curl http://127.0.0.1:9200/

打印结果：

{
  "name" : "node-1",
  "cluster_name" : "my-application",
  "cluster_uuid" : "cEKu_bLdTjyuVfW-EU_vJg",
  "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"
}
