docker 安装并运行 elasticsearch（单机版）

1.拉取指定版本的 ElasticSearch：

• 操作示例：

PS C:\WINDOWS\system32> docker image ls elasticsearch
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
elasticsearch       6.5.0               c9c606d302fb        2 years ago         351MB
PS C:\WINDOWS\system32>

3.创建ElasticSearch配置文件，数据目录，日志目录：

• 操作命令：

mkdir -p D:/SoftWare/data/DockerDataInfo/ElasticSearch6.5.0/config/
mkdir -p D:/SoftWare/data/DockerDataInfo/ElasticSearch6.5.0/data/
mkdir -p D:/SoftWare/data/DockerDataInfo/ElasticSearch6.5.0/logs/

• 操作示例：

PS C:\Users\54lxb\Desktop> mkdir -p D:/SoftWare/data/DockerDataInfo/ElasticSearch6.5.0/config/

    目录: D:\SoftWare\data\DockerDataInfo\ElasticSearch6.5.0
    
    Mode              LastWriteTime         Length Name
    ----              -------------         ------  ----

    d-----            2019/8/6  10:19             config

PS C:\Users\54lxb\Desktop> mkdir -p D:/SoftWare/data/DockerDataInfo/ElasticSearch6.5.0/data/

    目录: D:\SoftWare\data\DockerDataInfo\ElasticSearch6.5.0
    
    Mode              LastWriteTime         Length Name
    ----              -------------         ------  ----

    d-----            2019/8/6  10:20              data

PS C:\Users\54lxb\Desktop> mkdir -p D:/SoftWare/data/DockerDataInfo/ElasticSearch6.5.0/logs/

    目录: D:\SoftWare\data\DockerDataInfo\ElasticSearch6.5.0
    
    Mode              LastWriteTime         Length Name
    ----              -------------         ------  ----

    d-----             2019/8/6  10:21             logs
    
PS C:\Users\54lxb\Desktop> 

用文件管理器打开D:/SoftWare/data/DockerDataInfo/ElasticSearch6.5.0/config/目录，新建文件名为elasticsearch.xml的文件，然后打开文件，将下面的内容复制到刚才新建的文件中并并保存；

# ======================== 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: elasticSearch-6.5.0
#
# ------------------------------------ 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: /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
#
# 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 new node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
#discovery.zen.ping.unicast.hosts: ["host1", "host2"]
#
# Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):
#
#discovery.zen.minimum_master_nodes: 
#
# For more information, consult the zen discovery module documentation.
discovery.zen.minimum_master_nodes: 1
#
# ---------------------------------- 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

4.运行 ElasticSearch：

• 操作命令

docker run --restart=always -d --name elasticsearch6.5.0 -v  D:/SoftWare/data/DockerDataInfo/ElasticSearch6.5.0/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v D:/SoftWare/data/DockerDataInfo/ElasticSearch6.5.0/data:/usr/share/elasticsearch/data -v  D:/SoftWare/data/DockerDataInfo/ElasticSearch6.5.0/logs:/usr/share/elasticsearch/logs -p 9200:9200 -e "discovery.type=single-node" elasticsearch:6.5.0

• 操作示例：

PS C:\WINDOWS\system32> docker run --restart=always -d --name elasticsearch6.5.0 -v  D:/SoftWare/data/DockerDataInfo/ElasticSearch6.5.0/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v D:/SoftWare/data/DockerDataInfo/ElasticSearch6.5.0/data:/usr/share/elasticsearch/data -v  D:/SoftWare/data/DockerDataInfo/ElasticSearch6.5.0/logs:/usr/share/elasticsearch/logs -p 9200:9200 -e "discovery.type=single-node" elasticsearch:6.5.0
1e0f242864f3c89ea1aaea8c3c336d76c9dd8b811020107fb9bfe1db63dd556d
PS C:\WINDOWS\system32> 

5.验证 ElasticSearch 是否启动成功：

• 查看容器运行状态：

PS C:\WINDOWS\system32> docker ps
CONTAINER ID        IMAGE                 COMMAND                  CREATED             STATUS              PORTS                              NAMES
1e0f242864f3        elasticsearch:6.5.0   "/docker-entrypoint.…"   8 seconds ago       Up 4 seconds        0.0.0.0:9200->9200/tcp, 9300/tcp   elasticsearch6.5.0
PS C:\WINDOWS\system32>

通过以上信息，我们可以很清楚的了解到，ElasticSearch已经启动成功了！

• 直接访问：http://localhost:9200/，如果显示结果和下面的差不多，那就证明运行成功了；
