话不多说直接开整
首先是版本对应，SpringBoot和ES之间的版本必须要按照官方给的对照表进行安装，最新版本对照表如下：
（官网链接：https://docs.spring.io/spring-data/elasticsearch/docs/current/reference/html/#preface.requirements）
开始安装ES：
我本地的SpringBoot版本是2.3.4，所以我采用的ES版本是7.6.2版本，然后前往官网进行下载，小伙伴们也可以直接下载我所用的版本（链接：https://pan.baidu.com/s/1KoRo5h1nHY82c3B5RxfmrA 提取码：bcov）：
ES官方下载链接：https://www.elastic.co/cn/downloads/past-releases#elasticsearch
将下载下来的文件上传到服务器上，我上传的目录是usr/local/es，然后开始解压：
tar -zxvf elasticsearch-7.6.2-linux-x86_64.tar.gz
解压后修改config目录下的elasticsearch.yml文件，贴一下我修改的内容：
1 # ======================== Elasticsearch Configuration ========================= 2 # 3 # NOTE: Elasticsearch comes with reasonable defaults for most settings. 4 # Before you set out to tweak and tune the configuration, make sure you 5 # understand what are you trying to accomplish and the consequences. 6 # 7 # The primary way of configuring a node is via this file. This template lists 8 # the most important settings you may want to configure for a production cluster. 9 # 10 # Please consult the documentation for further information on configuration options: 11 # https://www.elastic.co/guide/en/elasticsearch/reference/index.html 12 # 13 # ---------------------------------- Cluster ----------------------------------- 14 # 15 # Use a descriptive name for your cluster: 16 # 这个是名字 17 cluster.name: my-application 18 # 19 # ------------------------------------ Node ------------------------------------ 20 # 21 # Use a descriptive name for the node: 22 # 这个是节点名称 23 node.name: es-node-0 24 # 25 # Add custom attributes to the node: 26 # 27 #node.attr.rack: r1 28 # 29 # ----------------------------------- Paths ------------------------------------ 30 # 31 # Path to directory where to store the data (separate multiple locations by comma): 32 # 这个是数据存放的路径 33 path.data: /usr/local/elasticsearch-7.6.2/data 34 # 35 # Path to log files: 36 # 这个是log存放的路径 37 path.logs: /usr/local/elasticsearch-7.6.2/logs 38 # 39 # ----------------------------------- Memory ----------------------------------- 40 # 41 # Lock the memory on startup: 42 # 43 #bootstrap.memory_lock: true 44 # 45 # Make sure that the heap size is set to about half the memory available 46 # on the system and that the owner of the process is allowed to use this 47 # limit. 48 # 49 50 51 # Elasticsearch performs poorly when the system is swapping the memory. 52 # 53 # ---------------------------------- Network ----------------------------------- 54 # 55 # Set the bind address to a specific IP (IPv4 or IPv6): 56 # 注：如果是云服务器的话需要填写内外地址，我这里是内网。 57 network.host: 192.168.0.4 58 http.host: 0.0.0.0 59 # 60 # Set a custom port for HTTP: 61 # 启动端口号 62 http.port: 9200 63 # 64 # For more information, consult the network module documentation. 65 # 66 # --------------------------------- discovery ---------------------------------- 67 # 68 # Pass an initial list of hosts to perform discovery when this node is started: 69 # The default list of hosts is ["127.0.0.1", "[::1]"] 70 # 71 #discovery.seed_hosts: ["host1", "host2"] 72 # 73 # Bootstrap the cluster using an initial set of master-eligible nodes: 74 # 初始化节点，可以有多个 75 cluster.initial_master_nodes: ["es-node-0"] 76 # 77 # For more information, consult the discovery and cluster formation module documentation. 78 # 79 # ---------------------------------- Gateway ----------------------------------- 80 # 81 # Block initial recovery after a full cluster restart until N nodes are started: 82 # 83 #gateway.recover_after_nodes: 3 84 # 85 # For more information, consult the gateway module documentation. 86 # 87 # ---------------------------------- VarIoUs ----------------------------------- 88 # 89 # Require explicit names when deleting indices: 90 # 91 #action.destructive_requires_name: true

因为安全问题elasticsearch 不让用root用户直接运行，所以要创建新用户：
useradd es passwd es
然后输入密码，最小8位数，为用户赋权限：
chown -R es:es /usr/local/es/
切换成es用户，cd 到bin目录下启动，第一种是前台启动，第二种是后台启动：
./elasticsearch
./elasticsearch -d
如果启动提示了这个错误需要在/etc/sysctl.conf文件最后添加一行
vm.max_map_count=262144
执行/sbin/sysctl -p 立即生效，之后再重新启动就好了；
在上面ES的yml配置中，我们配置了账号验证，所以我们需要重置一下ES账号的密码（确保es已经成功启动才能重置；在es的bin目录下执行）：
./elasticsearch-setup-passwords interactive
建议设置成相同的密码，方便记忆，设置成功后就可以直接打开网页去访问了，访问地址是ip:9200，然后输入账号：“elastic”，密码：“123456”（设置的123456）
能看到这些就代表ES已经成功启动了！！！
接下来我们开始配置Kibana：
Kibana的版本也需要和ES对应才行（官方地址：https://www.elastic.co/cn/support/matrix#matrix_compatibility）：
下载好的Kibana上传后进行解压缩：
tar -zxvf kibana-7.6.2-linux-x86_64.tar.gz
# Kibana is served by a back end server. This setting specifies the port to use. server.port: 5601 # Specifies the address to which the Kibana server will bind. IP addresses and host names are both valid values. # The default is 'localhost', which usually means remote machines will not be able to connect. # To allow connections from remote users, set this parameter to a non-loopback address. #server.host: "localhost"
# 代表都能访问 server.host: "0.0.0.0" # Enables you to specify a path to mount Kibana at if you are running behind a proxy. # Use the `server.rewriteBasePath` setting to tell Kibana if it should remove the basePath # from requests it receives, and to prevent a deprecation warning at startup. # This setting cannot end in a slash. #server.basePath: "" # Specifies whether Kibana should rewrite requests that are prefixed with # `server.basePath` or require that they are rewritten by your reverse proxy. # This setting was effectively always `false` before Kibana 6.3 and will # default to `true` starting in Kibana 7.0. #server.rewriteBasePath: false # The maximum payload size in bytes for incoming server requests. #server.maxPayloadBytes: 1048576 # The Kibana server's name. This is used for display purposes. #server.name: "your-hostname" # The URLs of the Elasticsearch instances to use for all your queries.
# 配置ES的地址 elasticsearch.hosts: ["http://192.168.0.4:9200"] # When this setting's value is true Kibana uses the hostname specified in the server.host # setting. When the value of this setting is false, Kibana uses the hostname of the host # that connects to this Kibana instance. #elasticsearch.preserveHost: true # Kibana uses an index in Elasticsearch to store saved searches, visualizations and # dashboards. Kibana creates a new index if the index doesn't already exist. #kibana.index: ".kibana" # The default application to load. #kibana.defaultAppId: "home" # If your Elasticsearch is protected with basic authentication, these settings provide # the username and password that the Kibana server uses to perform maintenance on the Kibana # index at startup. Your Kibana users still need to authenticate with Elasticsearch, which # is proxied through the Kibana server.
# ES的账号密码 elasticsearch.username: "elastic" elasticsearch.password: "123456" # Enables SSL and paths to the PEM-format SSL certificate and SSL key files, respectively. # These settings enable SSL for outgoing requests from the Kibana server to the browser. #server.ssl.enabled: false #server.ssl.certificate: /path/to/your/server.crt #server.ssl.key: /path/to/your/server.key # Optional settings that provide the paths to the PEM-format SSL certificate and key files. # These files are used to verify the identity of Kibana to Elasticsearch and are required when # xpack.security.http.ssl.client_authentication in Elasticsearch is set to required. #elasticsearch.ssl.certificate: /path/to/your/client.crt #elasticsearch.ssl.key: /path/to/your/client.key # Optional setting that enables you to specify a path to the PEM file for the certificate # authority for your Elasticsearch instance. #elasticsearch.ssl.certificateAuthorities: [ "/path/to/your/CA.pem" ] # To disregard the validity of SSL certificates, change this setting's value to 'none'. #elasticsearch.ssl.verificationMode: full # Time in milliseconds to wait for Elasticsearch to respond to pings. Defaults to the value of # the elasticsearch.requestTimeout setting. #elasticsearch.pingTimeout: 1500 # Time in milliseconds to wait for responses from the back end or Elasticsearch. This value # must be a positive integer. #elasticsearch.requestTimeout: 30000 # List of Kibana client-side headers to send to Elasticsearch. To send *no* client-side # headers, set this value to [] (an empty list). #elasticsearch.requestHeadersWhitelist: [ authorization ] # Header names and values that are sent to Elasticsearch. Any custom headers cannot be overwritten # by client-side headers, regardless of the elasticsearch.requestHeadersWhitelist configuration. #elasticsearch.customHeaders: {} # Time in milliseconds for Elasticsearch to wait for responses from shards. Set to 0 to disable. #elasticsearch.shardTimeout: 30000 # Time in milliseconds to wait for Elasticsearch at Kibana startup before retrying. #elasticsearch.startupTimeout: 5000 # Logs queries sent to Elasticsearch. Requires logging.verbose set to true. #elasticsearch.logQueries: false # Specifies the path where Kibana creates the process ID file. #pid.file: /var/run/kibana.pid # Enables you specify a file where Kibana stores log output. #logging.dest: stdout # Set the value of this setting to true to suppress all logging output. #logging.silent: false # Set the value of this setting to true to suppress all logging output other than error messages. #logging.quiet: false # Set the value of this setting to true to log all events, including system usage information # and all requests. #logging.verbose: false # Set the interval in milliseconds to sample system and process performance # metrics. Minimum is 100ms. Defaults to 5000. #ops.interval: 5000 # Specifies locale to be used for all localizable strings, dates and number formats. # Supported languages are the following: English - en , by default , Chinese - zh-CN .
# 配置中文 i18n.locale: "zh-CN"
