单机部署
创建用户：
useradd es
chown -R es /opt/soft/
mkdir -p /var/log/elastic
chown -R es /var/log/elastic
mkdir -p /tmp/elastic
chown -R es /tmp/elastic
系统参数配置：
echo "vm.max_map_count = 262144" >> /etc/sysctl.conf
sysctl -p
echo "* soft nofile 65536
* hard nofile 65536" >> /etc/security/limits.conf
方式一：YUM安装
rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch
echo "[elasticsearch]
name=Elasticsearch repository for 7.x packages
baseurl=https://artifacts.elastic.co/packages/7.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=0
autorefresh=1
type=rpm-md" >> /etc/yum.repos.d/elasticsearch.repo
yum install -y --enablerepo=elasticsearch elasticsearch
方式二：
cd /opt/soft/archive
wget https://mirrors.huaweicloud.com/elasticsearch/7.15.1/elasticsearch-7.15.1-linux-x86_64.tar.gz
tar -zxf elasticsearch-7.15.1-linux-x86_64.tar.gz -C ../
echo 'cluster.name: my-application
node.name: node-1
cluster.initial_master_nodes: ["node-1"]
discovery.seed_hosts: ["127.0.0.1"]
xpack.security.enabled: true
xpack.license.self_generated.type: basic
xpack.security.transport.ssl.enabled: true' >> /opt/soft/elasticsearch-7.15.1/config/elasticsearch.yml
配置
echo 'cluster.name: my-application
node.name: node-1
cluster.initial_master_nodes: ["node-1"]
discovery.seed_hosts: ["127.0.0.1"]
xpack.security.enabled: true
xpack.license.self_generated.type: basic
xpack.security.transport.ssl.enabled: true' >> /etc/elasticsearch/elasticsearch.yml
systemctl daemon-reload
启动
systemctl start elasticsearch
集群部署
xpack.security.enabled: true
xpack.license.self_generated.type: basic
xpack.security.transport.ssl.enabled: true
xpack.security.transport.ssl.verification_mode: certificate
xpack.security.transport.ssl.keystore.path: elastic-certificates.p12
xpack.security.transport.ssl.truststore.path: elastic-certificates.p12
（1）修改配置elasticsearch.yml：
- cluster.name # 一个集群内cluster name 需要相同
- node.name # 各个节点node name 唯一
- discovery.seed_hosts #
- network.host
- node.master # 主节点
- node.data # 数据节点
（2）生成CA证书：
bin/elasticsearch-certutil ca
使用第一步生成的证书，生成p12密钥：
bin/elasticsearch-certutil cert --ca elastic-stack-ca.p12
然后将证书复制到其余节点。
（3）然后启动所有节点，然后在主节点生成密码：文章来源：https://www.toymoban.com/news/detail-659220.html

查看集群状态：
curl -XGET 'http://<elasticsearch_host>:<elasticsearch_port>/_cluster/health?pretty=true'
