概要
本方案基于CentOS Linux release 7.6.1810 (Core)实践并编制，理论上兼容全部RHEL(红帽系)Red Hat Enterprise Linux (RHEL) 7系统及基于该发行版的衍生发行版。原生兼容Springboot2.7.x。方案采用rpm包三节点部署方式。
免责声明: 文档中全部IP仅为vmware虚拟机中绑定的ip。
安装步骤
准备三台机器。
操作步骤
|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| 三节点执行。 |
| 从官网下载获得 elasticsearch-7.17.20-x86_64.rpm (适配SpringBoot 2.7.3) elasticsearch-analysis-ik-7.17.18.zip |
| rpm -ivh elasticsearch-7.17.20-x86_64.rpm |
| mkdir /usr/share/elasticsearch/plugins/ik |
| unzip elasticsearch-analysis-ik-7.17.18.zip -d /usr/share/elasticsearch/plugins/ik |
| rm -rf /var/lib/elasticsearch 默认安装后生成，未运行前为空目录 |
| 找个大的目录做一下软连接 mkdir /data/elasticsearch/ ln -s /data/elasticsearch/ /var/lib/elasticsearch chmod 777 -R /var/lib/elasticsearch chmod 777 -R /data/elasticsearch |
| vim /usr/share/elasticsearch/plugins/ik/plugin-descriptor.properties 修改 elasticsearch.version=7.17.20 原本7.17.18 修改20即可，兼容 |
| 主节点执行: |
| 集群版修改方式: vim /etc/elasticsearch/elasticsearch.yml (记得保存) cluster.name: es-cluster node.name: node-1 network.host: xxx.xxx.xxx.xxx 具体机器ip discovery.seed_hosts: "xxx.xxx.200.52", "xxx.xxx.201.52", "xxx.xxx.202.52" 具体机器ip xpack.security.enabled: true 开启认证 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 cluster.initial_master_nodes: "node-1" 集群初始化节点 |
| systemctl start elasticsearch |
| 开启节点间加密传输 /usr/share/elasticsearch/bin/elasticsearch-certutil ca 回车两次,集群间都在内网，可以不使用证书密码。 /usr/share/elasticsearch/bin/elasticsearch-certutil cert --ca elastic-stack-ca.p12 回车三次 cp /usr/share/elasticsearch/elastic-certificates.p12 /etc/elasticsearch/ chmod 777 /etc/elasticsearch/elastic-certificates.p12 |
| 主节点向从节点发送数据 scp /etc/elasticsearch/elasticsearch.yml root@xxx.xxx.201.52:/etc/elasticsearch/ scp /etc/elasticsearch/elasticsearch.yml root@xxx.xxx.202.52:/etc/elasticsearch/ scp /etc/elasticsearch/elastic-certificates.p12 root@xxx.xxx.201.52:/etc/elasticsearch/ scp /etc/elasticsearch/elastic-certificates.p12 root@xxx.xxx.202.52:/etc/elasticsearch/ |
| |
| *******************仅主节点执行******************** 创建用户 /usr/share/elasticsearch/bin/elasticsearch-setup-passwords interactive y 重复 输入密码 |
| systemctl enable elasticsearch.service |
| 从节点执行 |
| vim /etc/elasticsearch/elasticsearch.yml (记得保存) 修改node.name 为node-2和node-3 修改node.host为从节点实际的ip 如xxx.xxx.201.52 删除 cluster.initial_master_nodes |
| systemctl start elasticsearch |
| 验证 浏览器访问 http://xxx.xxx.200.52:9200/_cat/nodes?v 换成具体ip 得到
