elasticsearch文档https://www.elastic.co/guide/en/elasticsearch/reference/8.9/targz.html kibana文档:https://www.elastic.co/guide/en/kibana/current/targz.html 2.安装步骤
无登录密码方式
2.1 环境准备
centos8 linux
若无shasum可以先安装
bash: shasum: 未找到命令 [rootlocalhost apps]# sudo yum install -y perl-Digest-SHA-1:6.02-1.el8.x86_64 [rootlocalhost apps]# sudo yum install -y perl-Digest-SHA 三台虚拟机或者linux服务器(docker方式此处不在描述) 192.168.23.12 master 192.168.23.13 slave 192.168.23.14 slave 下载文件进行解压(下载速度稍微有点慢)
[rootlocalhost apps] wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.8.2-linux-x86_64.tar.gz [rootlocalhost apps] wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.8.2-linux-x86_64.tar.gz.sha512 [rootlocalhost apps] shasum -a 512 -c elasticsearch-8.8.2-linux-x86_64.tar.gz.sha512 [rootlocalhost apps] tar -xzf elasticsearch-8.8.2-linux-x86_64.tar.gz
kbana在主节点上下载即可其他机器可以不用(集群例外)
[rootlocalhost apps]# wget https://artifacts.elastic.co/downloads/kibana/kibana-8.9.1-linux-x86_64.tar.gz [rootlocalhost apps]# curl https://artifacts.elastic.co/downloads/kibana/kibana-8.9.1-linux-x86_64.tar.gz.sha512 | shasum -a 512 -c - [rootlocalhost apps]# tar -xzf kibana-8.9.1-linux-x86_64.tar.gz 2.2 添加用户
elasticsearch启动不允许使用root用户导致
[rootlocalhost elasticsearch-8.8.2]# useradd kibana [rootlocalhost elasticsearch-8.8.2]# passwd kibana 2.3 修改文件profile文件
三台机器操作
添加ES_JAVA_HOME elasticsearch下自带有openjdk
[rootlocalhost apps]# vim /etc/profile export ES_JAVA_HOME/usr/local/apps/elasticsearch-8.9.1/jdk
[rootlocalhost apps]# source /etc/profile 2.4 修改elasticsearch.yml
/usr/local/apps/elasticsearch-8.9.1/config/ 注意data和logs节点需要自己建文件夹
xpack.security.enabled: false 默认这个配置是开启的配置文件中没有启动后如果正常一般有一堆的安全配置属性也包括这个(xpack.security.enabled: true)配置就麻烦很多而且kibana登录时也要配置
主节点 # 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: elastisearch # # ------------------------------------ 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: /usr/local/apps/esdata/data # # Path to log files: # path.logs: /usr/local/apps/esdata/logs # # ----------------------------------- 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: 192.168.23.12 # # 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: [192.168.23.13:9300, 192.168.23.14:9300] # # Bootstrap the cluster using an initial set of master-eligible nodes: # cluster.initial_master_nodes: [node-1] # # For more information, consult the discovery and cluster formation module documentation. # # ---------------------------------- Various ----------------------------------- # # Allow wildcard deletion of indices: # action.destructive_requires_name: false xpack.security.enabled: false 节点2
修改一下 network.host: 192.168.23.13 discovery.seed_hosts: [192.168.23.12:9300, 192.168.23.14:9300] cluster.initial_master_nodes: [node-1] 节点3 network.host: 192.168.23.14 discovery.seed_hosts: [192.168.23.12:9300, 192.168.23.13:9300] cluster.initial_master_nodes: [node-1] 几台机器都修改jvm.options文件 -Xms512M -Xmx512M 2.5 修改 sysctl.conf
Virtual memory | Elasticsearch Guide [8.9] | Elastic
[rootlocalhost apps]#vim /etc/sysctl.conf vm.max_map_count262144 [rootlocalhost apps]# sysctl -p
2.6 修改kibana下的
/usr/local/apps/kibana-8.9.1/config/kibana.yml server.port: 5601 server.host: 192.168.23.12 3.启动
3.1 切换到kibana
如果遇到权限问题
可以使用root用户赋权如 chown -R kibana kibana /usr/local/apps/elasticsearch-8.9.1
[rootlocalhost elasticsearch-8.9.1]# su kibana
3.2 启动elasticsearch [kibanalocalhost bin]$ /usr/local/apps/elasticsearch-8.9.1/bin/elasticsearch 三台启动完成后在主节点上启动
3.3 启动kibana
[kibanalocalhost bin]$ /usr/local/apps/kibana-8.9.1/bin/kibana
初次启动需要在浏览器上访问一下控制台打的URL然后才能正常访问
http://192.168.23.12:5601/ 3.4 验证节点情况
