1.官网下载 Elasticsearch https://www.elastic.co/cn/downloads/past-releases/#elasticsearch 2.解压软件 tar -zxvf elasticsearch-6.8.23.tar.gz -C /opt/soft/3.创建用户
因为安全问题Elasticsearch 不允许 root 用户直接运行所以要创建新用户在 root 用户中创建新用户
useradd es #新增 es 用户
passwd es #为 es 用户设置密码
userdel -r es #如果错了可以删除再加
设置用户 es 密码 es 赋权ES用户
chown -R es:root /opt/soft/elasticsearch-6.8.23/ #文件夹所有者###创建es数据目录 并且赋权
mkdir -p /home/data/elastic-6.8.23
mkdir /home/data/elastic-6.8.23/data
mkdir /home/data/elastic-6.8.23/logs
mkdir /home/data/elastic-6.8.23/es_bak数据日志文件夹所有者
chown -R es:root /home/data/elastic-6.8.234.修改配置文件

内存设置大一点 ## JVM configuration################################################################
## IMPORTANT: JVM heap size
################################################################
##
## You should always set the min and max JVM heap
## size to the same value. For example, to set
## the heap to 4 GB, set:
##
## -Xms4g
## -Xmx4g
##
## See https://www.elastic.co/guide/en/elasticsearch/reference/current/heap-size.html
## for more information

5.启动软件
使用 ES 用户启动
cd /opt/es/
#启动
bin/elasticsearch
#后台启动
bin/elasticsearch -d
启动时会动态生成文件bin/elasticsearch 报错 启动时会动态生成文件如果文件所属用户不匹配会发生错误需要重新进行修改用户和用户组 root 用户 再附权一下 chown -R es:es /opt/soft/elasticsearch-6.8.23/关闭防火墙
#暂时关闭防火墙
systemctl stop firewalld
#永久关闭防火墙
systemctl enable firewalld.service #打开放货抢永久性生效重启后不会复原
systemctl disable firewalld.service #关闭防火墙永久性生效重启后不会复原切换用户 ess
su es
#启动
bin/elasticsearch6.测试
如果配置没生效 可以重启
sudo reboothttp://192.168.6.101:9200/ http://192.168.6.101:9200/_cat/indices?v 开启密码访问
1.配置elasticsearch.yml
vim /data/elasticsearch-6.8.23/config/elasticsearch.yml#以下配置用于设置密码访问ES集群如不需要可以不用
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
2.在 config 下生成 elastic-certificates.p12 文件
cd /opt/soft/elasticsearch-6.8.23bin/elasticsearch-certutil cert -out config/elastic-certificates.p12 -pass 如果有证书密码
命令
elasticsearch-certutil cert -out elastic-certificates.p12 -pass 证书密码如果有证书密码配置证书密码
elasticsearch-keystore add xpack.security.transport.ssl.keystore.secure_password
elasticsearch-keystore add xpack.security.transport.ssl.truststore.secure_password证书文件elastic-certificates.p12需拷贝到所有ES节点对应的conf目录下 3.重启ElasticSearch服务3台服务器都需要执行
jps #查询ES服务进程号
kill -9 xxx #杀掉ES进程关闭服务chown -R es:es /opt/soft/elasticsearch-6.8.23 cd /data/elasticsearch-6.8.10/bin
./elasticsearch -d #启动服务4.配置对外访问的用户名/密码自动或手工
#自动设置密码
elasticsearch-setup-passwords auto#手动设置密码
bin/elasticsearch-setup-passwords interactive随后按照提示依次输入 以下这6个用户的密码完成后数据会自动同步至其他2个节点。
elasticapm_systemkibana、logstash_system、beats_system、remote_monitoring_user
5.测试
关闭防火墙
#暂时关闭防火墙
systemctl stop firewalld
#永久关闭防火墙
systemctl enable firewalld.service #打开放货抢永久性生效重启后不会复原
systemctl disable firewalld.service #关闭防火墙永久性生效重启后不会复原http://192.168.2.89:9200/ http://192.168.2.89:9200/_cat/indices?v 账号elastic 密码刚输入的6位密码
