预先解决可能会遇到的问题
启动问题
问题一：max file descriptors [4096] for elasticsearch process likely too low, increase to at least [65536] 问题二：max number of threads [1024] for user [lish] likely too low, increase to at least [2048]
问题三：max virtual memory areas vm.max_map_count [65530] likely too low, increase to at least [262144] 解决：切换到root用户修改配置sysctl.conf vi /etc/sysctl.conf 添加下面配置：
################################################################ ## IMPORTANT: JVM heap size ################################################################ ## ## You should always set the min and max JVM heap ## size to the same value. For example, to set ## the heap to 4 GB, set: ## ## -Xms4g ## -Xmx4g ## ## See https://www.elastic.co/guide/en/elasticsearch/reference/current/heap-size.html ## for more information ## ################################################################
# Xms represents the initial size of total heap space # Xmx represents the maximum size of total heap space
-Xms256m -Xmx256m

# ======================== 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# 1 设置节点名称 # # 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: /path/to/data # # Path to log files: # #path.logs: /path/to/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 ----------------------------------- # # Set the bind address to a specific IP (IPv4 or IPv6): # network.host:0.0.0.0# 2 设置网络地址绑定 # # Set a custom port for HTTP: # #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: ["host1", "host2"] # # Bootstrap the cluster using an initial set of master-eligible nodes: # cluster.initial_master_nodes: ["node-1"] # 3 设置初始主节点 # # For more information, consult the discovery and cluster formation module documentation. # # ---------------------------------- Gateway ----------------------------------- # # Block initial recovery after a full cluster restart until N nodes are started: # #gateway.recover_after_nodes: 3 # # For more information, consult the gateway module documentation. # # ---------------------------------- Various ----------------------------------- # # Require explicit names when deleting indices: # #action.destructive_requires_name: true

# 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" server.host:0.0.0.0# 1 设置网络地址绑定
# 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. #elasticsearch.hosts: ["http://localhost:9200"] # 设置elasticsearch的访问地址，默认本机
# 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. #elasticsearch.username: "user" #elasticsearch.password: "pass"
# 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 validate that your Elasticsearch backend uses the same key files. #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. #i18n.locale: "en"
