准备:
elasticsearch-7.15.0-x86_64.rpm
kibana-7.15.0-x86_64.rpm
注：一定要同版本
三台服务器（虚拟ip）
192.168.21.11
192.168.21.12
192.168.21.13
关闭防火墙（所有）：
启动：systemctl start firewalld
关闭：systemctl stop firewalld
查看状态：systemctl status firewalld
开机禁用：systemctl disable firewalld
开机启用：systemctl enable firewalld
安装步骤首先安装Elasticsearch（所有））
使用命令
rpm -ivh elasticsearch-7.15.0-x86_64.rpm
进行安装安装后
执行命令进行启动
systemctl start elasticsearch.service
启动成功后执行命令
curl 192.168.21.11:9200
返回如下表示成功
按照如下修改配置文件 /etc/elasticsearch (所有节点)
# ======================== Elasticsearch Configuration ========================= # # NOTE: Elasticsearch comes with reasonable defaults for most settings. # Before you set out to tweak and tune the configuration, make sure you # understand what are you trying to accomplish and the consequences. # # The primary way of configuring a node is via this file. This template lists # the most important settings you may want to configure for a production cluster. # # Please consult the documentation for further information on configuration options: # https://www.elastic.co/guide/en/elasticsearch/reference/index.html # # ---------------------------------- Cluster ----------------------------------- # # Use a descriptive name for your cluster: # cluster.name: my-application # # ------------------------------------ Node ------------------------------------ # # Use a descriptive name for the node: # node.name: node-1 # # Add custom attributes to the node: # #node.attr.rack: r1 # # ----------------------------------- Paths ------------------------------------ # # Path to directory where to store the data (separate multiple locations by comma): # path.data: /var/lib/elasticsearch # # Path to log files: # path.logs: /var/log/elasticsearch # # ----------------------------------- Memory ----------------------------------- # # Lock the memory on startup: # #bootstrap.memory_lock: true # # Make sure that the heap size is set to about half the memory available # on the system and that the owner of the process is allowed to use this # limit. # # Elasticsearch performs poorly when the system is swapping the memory. # # ---------------------------------- Network ----------------------------------- # # By default Elasticsearch is only accessible on localhost. Set a different # address here to expose this node on the network: # network.host: 0.0.0.0 # # By default Elasticsearch listens for HTTP traffic on the first free port it # finds starting at 9200. Set a specific HTTP port here: # #http.port: 9200 # # For more information, consult the network module documentation. # # --------------------------------- Discovery ---------------------------------- # # Pass an initial list of hosts to perform discovery when this node is started: # The default list of hosts is ["127.0.0.1", "[::1]"] # discovery.seed_hosts: ["192.168.21.11:9300", "192.168.21.12:9300","192.168.21.13:9300"] # # Bootstrap the cluster using an initial set of master-eligible nodes: # #cluster.initial_master_nodes: ["192.168.21.11:9300"] # # For more information, consult the discovery and cluster formation module documentation. # # ---------------------------------- Various ----------------------------------- # # Require explicit names when deleting indices: # #action.destructive_requires_name: true
其中 cluster.name ：集群名 （注：需三台全部一致）
node.name：节点名 （注：三台不能一致）
discovery.seed_hosts：所有节点的ip
cluster.initial_master_nodes: master预选节点 只有master配置就行 只需一个节点配
其余按文档固定配置就可以，配置完成后执行命令(所有)
/etc/security/limits.conf文件下end前添加:
* soft nofile 65536 * hard nofile 65536
添加后执行:
echo 'vm.max_map_count=655360' >> /etc/sysctl.conf #查看配置,如果未生效重启配置 ulimit -n
修改后执行命令重启(所有)
systemctl restart elasticsearch.service
重启后,在网页执行
http://192.168.21.11:9200/_cluster/state?pretty
得到如图结果
表示集群配置完毕。
接下来安装Kibana （选择一台进行安装即可）
使用命令安装rpm
rpm -ivh kibana-7.15.0-x86_64.rpm
安装后修改kibana.yml配置文件使用如下配置：
server.port: 5601 server.host: "0.0.0.0" elasticsearch.hosts: ["http://localhost:9200"] i18n.locale: "zh-CN"
配置完成执行命令进行启动
//启动服务 systemctl start kibana.service //查看状态 systemctl status kibana.service //停止服务 systemctl stop kibana.service
启动后通过 http://192.186.21.11:5601/ 进行访问
附录
访问后可通过
栏输入
GET /_cat/nodes?v
查询当前集群节点。
通过执行如下命令设置开机自启动：
// kibana 设置服务开机自启 systemctl enable kibana.service // es 开机自启 systemctl daemon-reload systemctl enable elasticsearch.service
