将 SELINUXenforcing 改为 SELINUXdisabled ------ 配置主机名各节点对应执行 ------ hostnamectl set-hostname es-master-1 # 10.10.10.25 hostnamectl set-hostname es-master-2 # 10.10.10.26 hostnamectl set-hostname es-master-3 #

主节点es-master-1/2/3 cluster.name: elk-cluster node.name: es-master-1 node.master: true node.data: false node.ingest: false network.host: 0.0.0.0 http.port: 9200 transport.port: 9300 discovery.seed_hosts: [es-master-1,es-master-2,es-master-3,es-data-1,es-stack-1,es-data-2] cluster.initial_master_nodes: [es-master-1,es-master-2,es-master-3] http.cors.enabled: true http.cors.allow-origin: * path.data: /usr/local/elk/elasticsearch/data path.logs: /usr/local/elk/elasticsearch/logs bootstrap.memory_lock: false bootstrap.system_call_filter: false network.bind_host: 0.0.0.0 network.publish_host: 10.10.10.25 discovery.zen.minimum_master_nodes: 2 cluster.election.max_timeout: 30s xpack.security.enabled: true xpack.security.transport.ssl.enabled: true xpack.security.transport.ssl.keystore.path: elastic-certificates.p12 xpack.security.transport.ssl.truststore.path: elastic-certificates.p12 xpack.security.transport.ssl.keystore.password: xpack.security.transport.ssl.truststore.password: xpack.security.transport.ssl.verification_mode: none xpack.security.http.ssl.enabled: false # 数据节点es-data-1 / es-stack-1 / es-data-2 # 与主节点相比仅改node.master: false、node.data: true、node.ingest: true、 # node.name 和 network.publish_host 填各自值其余相同。 ------ 生成 SSL 证书仅 es-master-1elk 用户 ------ su elk cd /usr/local/elk/elasticsearch/bin ./elasticsearch-certutil cert -out /usr/local/elk/elasticsearch/config/elastic-certificates.p12 -pass ------ 同步证书到所有节点仅 es-master-1root 用户 ------ su root scp /usr/local/elk/elasticsearch/config/elastic-certificates.p12 rootes-master-2:/usr/local/elk/elasticsearch/config/ scp /usr/local/elk/elasticsearch/config/elastic-certificates.p12 rootes-master-3:/usr/local/elk/elasticsearch/config/ scp /usr/local/elk/elasticsearch/config/elastic-certificates.p12 rootes-data-1:/usr/local/elk/elasticsearch/config/ scp /usr/local/elk/elasticsearch/config/elastic-certificates.p12 rootes-stack-1:/usr/local/elk/elasticsearch/config/ scp /usr/local/elk/elasticsearch/config/elastic-certificates.p12 rootes-data-2:/usr/local/elk/elasticsearch/config/ ------ 授权证书权限所有节点root 用户 ------ chown elk:elk /usr/local/elk/elasticsearch/config/elastic-certificates.p12 chmod 600 /usr/local/elk/elasticsearch/config/elastic-certificates.p12 四、Kibana 部署【仅 es-stack-1】 ------ 下载并解压 ------ su elk cd /usr/local/elk wget https://artifacts.elastic.co/downloads/kibana/kibana-7.17.9-linux-x86_64.tar.gz tar -zxvf kibana-7.17.9-linux-x86_64.tar.gz mv kibana-7.17.9-linux-x86_64 kibana ------ 配置 kibana.yml ------ vi /usr/local/elk/kibana/config/kibana.yml server.port: 5601 server.host: 0.0.0.0 server.name: es-stack-1 elasticsearch.hosts: [http://10.10.10.25:9200, http://10.10.10.26:9200, http://10.10.10.27:9200] i18n.locale: zh-CN logging.dest: /usr/local/elk/kibana/logs/kibana.log 五、集群启动与初始化 ------ 启动所有 ES 节点所有节点elk 用户 ------ su elk cd /usr/local/elk/elasticsearch/bin ./elasticsearch -d # 验证ps -ef | grep elasticsearch | grep -v grep ------ 生成内置用户密码仅 es-master-1elk 用户 ------ su elk cd /usr/local/elk/elasticsearch/bin ./elasticsearch-setup-passwords auto # 记录 elastic 和 kibana_system 两个密码参考《密码备份.txt》 ------ 完善 Kibana 配置并启动仅 es-stack-1 ------ su elk vi /usr/local/elk/kibana/config/kibana.yml # 追加 # elasticsearch.username: kibana_system # elasticsearch.password: kibana_system密码 cd /usr/local/elk/kibana/bin nohup ./kibana /dev/null 21 # 验证ps -ef | grep kibana | grep -v grep 六、验证 ------ 任意节点执行 ------ curl -u elastic:elastic密码 http://127.0.0.1:9200 curl -u elastic:elastic密码 http://127.0.0.1:9200/_cluster/health?pretty curl -u elastic:elastic密码 http://127.0.0.1:9200/_cat/nodes?v ------ 访问 Kibana ------ # 浏览器打开 http://10.10.10.29:5601用 elastic 账号登录 七、常见问题速查 1. ES 启动失败权限不足 - chown -R elk:elk /usr/local/elk/elasticsearch 2. SSL 握手 No name matching - 配置 verification_mode: none 3. 节点无法发现 - 检查防火墙、hosts、discovery.seed_hosts 4. Kibana 连不上 ES - 核对 kibana.yml 账号密码与 ES 地址 手册结束
