安装 Elastic Search

下载及安装

1. 官方下载地址
2. 下载并解压

启动 Elastic search

双击bin\elasticsearch.bat 启动
启动成功之后就会在localhost:9200看到相应的数据信息

控制台中文乱码， 需要在config/jvm.options文件中添加

# ensure UTF-8 encoding by default (e.g. filenames)
-Dfile.encoding=GBK

在启动过程中可能会出现一些问题， 这里有解决方法地址

插件安装

安装插件之前需要安装node.js.
插件版本匹配信息

issue: Plugin [kibana-8.5.0] is missing a descriptor properties file.
这是由于版本不匹配导致的错误
我的elasticsearch version: 8.4.3
kibana version: 8.4.3
在启动过程中可能会找properties文件，在8.4.3版本中并没有这个文件， 文件名为plugin-descriptor.properties，可以copy一下：

# Elasticsearch plugin descriptor file
# This file must exist as 'plugin-descriptor.properties' at
# the root directory of all plugins.
#
# A plugin can be 'site', 'jvm', or both.
#
### example site plugin for "foo":
#
# foo.zip <-- zip file for the plugin, with this structure:
#   _site/ <-- the contents that will be served
#   plugin-descriptor.properties <-- example contents below:
#
# site=true
# description=My cool plugin
# version=1.0
#
### example jvm plugin for "foo"
#
# foo.zip <-- zip file for the plugin, with this structure:
#   .jar <-- classes, resources, dependencies
#   .jar <-- any number of jars
#   plugin-descriptor.properties <-- example contents below:
#
# jvm=true
# classname=foo.bar.BazPlugin
# description=My cool plugin
# version=2.0.0-rc1
# elasticsearch.version=2.0
# java.version=1.7
#
### mandatory elements for all plugins:
#
# 'description': simple summary of the plugin
description=Kibana for Elasticsearch
#
# 'version': plugin's version
version=8.4.3
#
# 'name': the plugin name
name=kibana
#
# 'classname': the name of the class to load, fully-qualified.
classname=org.elasticsearch.plugin.kibana
#
# 'java.version' version of java the code is built against
# use the system property java.specification.version
# version string must be a sequence of nonnegative decimal integers
# separated by "."'s and may have leading zeros
java.version=1.8
#
# 'elasticsearch.version' version of elasticsearch compiled against
# You will have to release a new version of the plugin for each new
# elasticsearch release. This version is checked when the plugin
# is loaded so Elasticsearch will refuse to start in the presence of
# plugins with the incorrect elasticsearch.version.
elasticsearch.version=8.4.3

如何在开发机上运行多个实例

bin/elasticsearch -E node.name=node1 -E cluster.name=geedtime -E path.data=node1_data
bin/elasticsearch -E node.name=node2 -E cluster.name=geedtime -E path.data=node2_data

删除进程

ps grep|elasticsearch
