elasticsearch(es)的安装-macOs，cp-R7.10.2
前提：已经安装过jdk1.8
java -version #查看jdk版本
1.es的安装和访问
es安装
brew install elasticsearch #安装 brew info elasticsearch # 查看es信息 brew services start elasticsearch # 启动
浏览器输入：localhost:9200 查看es
2.kibana的安装和访问
kibana可以通过可视化的界面操作访问es
- kibana安装
brew install kibana #安装 brew info kibana # 查看信息 brew services start kibana #启动
- kibana访问:浏览器访问 localhost:5601，找到开发工具（Dev Tools），向es中插入数据&搜索数据
3.es集群搭建
之前是通过brew命令安装的es，虽然一键很爽，但是要搭建集群，按照下述文章搭建单机版es集群的说法，需要找到安装包
## 查看全部安装路径 brew list ## 查看指定软件安装路径 brew list 软件名
实战
brew list elasticsearch ## 结果 /usr/local/Cellar/elasticsearch/7.10.2/.bottle/etc/ (3 files) /usr/local/Cellar/elasticsearch/7.10.2/bin/elasticsearch /usr/local/Cellar/elasticsearch/7.10.2/bin/elasticsearch-keystore /usr/local/Cellar/elasticsearch/7.10.2/bin/elasticsearch-plugin /usr/local/Cellar/elasticsearch/7.10.2/bin/elasticsearch-shard /usr/local/Cellar/elasticsearch/7.10.2/homebrew.mxcl.elasticsearch.plist /usr/local/Cellar/elasticsearch/7.10.2/libexec/bin/ (8 files) /usr/local/Cellar/elasticsearch/7.10.2/libexec/lib/ (42 files) /usr/local/Cellar/elasticsearch/7.10.2/libexec/modules/ (93 files)
查看通过安装包安装es的文章安装包安装es-mac，可以看到，/usr/local/Cellar/elasticsearch/7.10.2/ 其实就是安装包，试着复制，然后安装。
cp -R 7.10.2 7.10.2.backup1 cp -R 7.10.2 7.10.2.backup2
得到两个安装包的副本后，修改副本中的配置文件
但是进文件夹里看，并没有config文件夹，通过brew命令查看es安装情况，可以得到config路径：/usr/local/etc/elasticsearch/
和我假设的不一致。/usr/local/Cellar/elasticsearch/7.10.2/ 并不是安装包，只是通过brew命令后的安装路径。
brew info elasticsearch
## 结果
From:https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/elasticsearch.rb
Config: /usr/local/etc/elasticsearch/
通过brew命令还可以得到安装包路径：https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/elasticsearch.rb 点进去后得到rul：https://github.com/elastic/elasticsearch/archive/v7.10.2.tar.gz。点击下载、解压后目录如下，也没有config目录。
考虑从官网下载：https://www.elastic.co/cn/start ，此时有config目录了
检查已有es的config文件里的cluster name。将两者修改成一致。cyx_elasticsearch
## 通过brew安装的es的yml文件，路径：/usr/local/etc/elasticsearch/ cluster.name: elasticsearch_brew ## 通过官网下载的es里的yml文件，路径：~/software/es/es-a/elasticsearch-8.0.1/config cluster.name: my-application
elasticsearch.yml文件的解释&修改
# ======================== 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: cyx-application # # ------------------------------------ Node ------------------------------------ # # Use a descriptive name for the node: # node.name: node-1 # 是否有资格选举为主节点 node.master: true # 是否存储数据 node.data: true # 最大集群节点数 node.max_local_storage_nodes: 3 # # 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: /Users/yuxichen/software/es/es-a/data # # Path to log files: # path.logs: /Users/yuxichen/software/es/es-a/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: 192.168.0.1 # # By default Elasticsearch listens for HTTP traffic on the first free port it # finds starting at 9200. Set a specific HTTP port here: # 端口号 http.port: 9201 # 内部节点之间沟通端口 transport.tcp.port: 9500 # # 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]"] # 候选主节点地址 # discovery.seed_hosts: ["127.0.0.1:9300", "127.0.0.1:9400"] # # Bootstrap the cluster using an initial set of master-eligible nodes: # cluster.initial_master_nodes: ["node-1", "node-2"] # # For more information, consult the discovery and cluster formation module documentation. # # ---------------------------------- Various ----------------------------------- # # Allow wildcard deletion of indices: # #action.destructive_requires_name: false
总结下，yml文件需要修改的配置
cluster.name: cyx-application node.name: node-1 node.master: true node.data: true node.max_local_storage_nodes: 3 path.data: /Users/yuxichen/software/es/es-a/data path.logs: /Users/yuxichen/software/es/es-a/logs http.port: 9201 transport.tcp.port: 9500 discovery.seed_hosts: ["127.0.0.1:9200", "127.0.0.1:9201"] cluster.initial_master_nodes: ["node-1", "node-2"]
配置完三个节点的yml后，开始关闭已经启动的es
brew services stop elasticsearch #输出 Stopping `elasticsearch`... (might take a while) ==> Successfully stopped `elasticsearch` (label: homebrew.mxcl.elasticsearch)
试着启动三个节点
#通过brew安装的 brew services start elasticsearch #输出 ==> Successfully started `elasticsearch` (label: homebrew.mxcl.elasticsearch) #通过下载的安装包启动 ./bin/elasticsearch ##输出 报错一：node.master设置找不到 报错二：transport.tcp.port: 设置找不到
把这些都删除后，直接在浏览器中输入localhost:9201，提示需要用户名密码，但是我又没设置过，在官网文档elasticsearch8.0.1
和网上的文档也没有找到第一次登陆需要用户名密码的原因。就在配置文件中设置了不需要鉴权
可以启动的官网下载的elasticsearch8.0.1版本的yml文件修改如下
cluster.name: cyx-application node.name: node-1 path.data: /Users/yuxichen/software/es/es-a/data path.logs: /Users/yuxichen/software/es/es-a/logs http.port: 9201 cluster.initial_master_nodes: ["node-1", "node-2"] xpack.security.enabled: false
接下来测试集群是否搭建成功&配置kibana
测试集群，输出结果如下，可以看出节点总数为1，所以集群没有搭建成功，需要找下原因
http://localhost:9200/_cat/health?v
实在是找不到原因，只好放弃8.0.1这个版本太新了，下载了稍微老一点的版本：7.16.0，按照常见文章的配置，看上去是成功了
配置了下kibana，然后查看集群健康，发现竟然是red，我要哭了
整了半天还是一直是yellow，且node-2、3启动时候报错，搞不定了，先去洗漱睡了好困啊啊啊啊
