安装
整个stack的安装顺序
- Elasticsearch 本体
- Kibana 分析平台
- Logstash 日志收集
- Beats 日志发送
- APM Server 性能监控
- Elasticsearch Hadoop
解压缩，执行bin/elasticsearch.bat 启动后测试，GET localhost:9200，效果如图
配置
主要配置文件
- elasticsearch.yml
- jvm.options
- log4j2.properties 默认配置文件位置：$ES_HOME/config 通过环境变量修改配置文件位置：
ES_PATH_CONF=/path/to/my/config ./bin/elasticsearch重要的配置 configelasticsearch.yml
代码语言：javascript复制# 数据和日志路径
path:
data: /var/lib/elasticsearch
logs: /var/log/elasticsearch
# 不指定的话，默认从9200开始查找的一个可用端口
http.port: 9200
# 集群名称
cluster.name: logging-prod
# 节点名称
node.name: prod-data-2
# 默认只能通过localhost访问，设置IP地址可将节点暴露到网络上
# 一旦制定了这个配置，则以生产模式启动，单机模式的警告项目将变成异常导致启动失败
network.host: 192.168.0.1
# 生产模式需要配置这两项，分别指定集群主机和master节点名称
# host不指定端口的话为9300，
discovery.seed_hosts: ["192.168.0.1", "host2"]
cluster.initial_master_nodes: ["node-1", "node-2"]报错

启动失败原因 没有配置discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes
