### 一、Docker 部署 ElasticSearch ###

1、从仓库中查找所有ElasticSearch的镜像

[hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ pwd
    /home/hn_home/docker/elasticsearch
    
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ docker search elasticsearch
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$

2、选择一个版本镜像进行拉取

[hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ docker pull docker.io/library/elasticsearch:7.6.2
    Trying to pull repository docker.io/library/elasticsearch ... 
    7.6.2: Pulling from docker.io/library/elasticsearch

    d7e8c1e99b9a: Pull complete 
    85c4d6c81438: Pull complete 
    3119218fac98: Pull complete 
    914accf214bb: Pull complete 
    Digest: sha256:59342c577e2b7082b819654d119f42514ddf47f0699c8b54dc1f0150250ce7aa
    Status: Downloaded newer image for docker.io/library/elasticsearch:7.6.2
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ ll
    total 0

3、 查看镜像

[hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ 
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ docker images
    REPOSITORY                                      TAG                 IMAGE ID            CREATED             SIZE
    docker.io/redis                                 latest              ef47f3b6dc11        5 weeks ago         104 MB
    docker.io/mysql                                 latest              dd7265748b5d        2 months ago        545 MB
    docker.elastic.co/elasticsearch/elasticsearch   7.6.2               f29a1ee41030        10 months ago       791 MB
    docker.io/elasticsearch                         7.6.2               f29a1ee41030        10 months ago       791 MB
    docker.io/mongo                                 4.2.1               965553e202a4        14 months ago       363 MB
    docker.io/java                                  8                   d23bdf5b1b1b        4 years ago         643 MB
    docker.io/mobz/elasticsearch-head               5                   b19a5c98e43b        4 years ago         824 MB

4、通过镜像，启动一个容器，并将9200和9300端口映射到本机（`ElasticSearch`的默认端口是9200，我们把宿主环境9200端口映射到`Docker`容器中的9200端口）

然后把文件的映射全部映射到宿主机

[hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ mkdir data
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ mkdir logs
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ mkdir plugins
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ 
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ 
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ chmod -R 775 data
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ chmod -R 775 logs
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ chmod -R 775 plugins
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ 
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ 
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ ll
    total 12
    drwxrwxr-x 2 hn-zcsjw hn-zcsjw 4096 Jan 21 09:46 data
    drwxrwxr-x 2 hn-zcsjw hn-zcsjw 4096 Jan 21 09:46 logs
    drwxrwxr-x 2 hn-zcsjw hn-zcsjw 4096 Jan 21 09:46 plugins
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ 
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ 
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ 
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ docker run -p 9200:9200 -p 9300:9300 
    --privileged=true --name es7.6.2 \
    -e "discovery.type=single-node" \
    -e ES_JAVA_OPTS="-Xms512m -Xmx1024m" \
    -v /home/hn_home/docker/elasticsearch/plugins:/usr/share/elasticsearch/plugins \
    -v /home/hn_home/docker/elasticsearch/data:/usr/share/elasticsearch/data \
    -v /home/hn_home/docker/elasticsearch/logs:/usr/share/elasticsearch/logs \
    -d elasticsearch:7.6.2
    d0e751a0047da73bcaf7ae9109183e74aeb028d80dbdf074973b313220ef5f6f
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$

把容器内Elasticsearch的配置文件复制到本地：如果有修改配置文件的需求的话

#从容器内，将配置文件copy出来
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ 
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ docker cp -a es7.6.2:/usr/share/elasticsearch/config/ /home/hn_home/docker/elasticsearch/
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ 
    
    给Elastic配置可访问IP、以及ES_Name配置
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ 
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ sudo chmod 776 config/elasticsearch.yml 
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ vi config/elasticsearch.yml
    #如下配置写入
    cluster.name: "docker-cluster"
    network.host: 0.0.0.0
    
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ cat config/elasticsearch.yml
    cluster.name: "docker-cluster"
    network.host: 0.0.0.0
    
    
    然后删除已运行的容器
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ docker stop es7.6.2
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ 
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ docker rm es7.6.2
    
    然后重新运行，参数全部使用本地的挂载
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ docker run -p 9200:9200 -p 9300:9300 \
    --privileged=true --name es7.6.2 \
    -e "discovery.type=single-node" \
    -e ES_JAVA_OPTS="-Xms512m -Xmx1024m" \
    -v /home/hn_home/docker/elasticsearch/plugins:/usr/share/elasticsearch/plugins \
    -v /home/hn_home/docker/elasticsearch/data:/usr/share/elasticsearch/data \
    -v /home/hn_home/docker/elasticsearch/logs:/usr/share/elasticsearch/logs \
    -v /home/hn_home/docker/elasticsearch/config:/usr/share/elasticsearch/config \
    -d elasticsearch:7.6.2
    
    7eaeef682d2897703059e137406dbb1e01fd23e2b7493a57c1e17ebea970dd0e
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$

5、 浏览器访问ip:9200

{
      "name" : "f03270ef8672",
      "cluster_name" : "docker-cluster",
      "cluster_uuid" : "mgb4vDWvQCWTgvkPG3TU4Q",
      "version" : {
        "number" : "7.6.2",
        "build_flavor" : "default",
        "build_type" : "docker",
        "build_hash" : "ef48eb35cf30adf4db14086e8aabd07ef6fb113f",
        "build_date" : "2020-03-26T06:34:37.794943Z",
        "build_snapshot" : false,
        "lucene_version" : "8.4.0",
        "minimum_wire_compatibility_version" : "6.8.0",
        "minimum_index_compatibility_version" : "6.0.0-beta1"
      },
      "tagline" : "You Know, for Search"
    }

### **二、Docker部署ik中文分词插件** ###

1、进入es容器内部，/plugins下新建ik文件夹

[hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ cd plugins/
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z plugins]$ mkdir ik
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z plugins]$ ll
    total 4
    drwxrwxr-x 2 hn-zcsjw hn-zcsjw 4096 Jan 21 10:09 ik
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z plugins]$ cd ik
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z ik]$ 
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z ik]$ wget https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.6.2/elasticsearch-analysis-ik-7.6.2.zip
    100%[===============================================================================>] 4,504,473   21.5KB/s   in 4m 3s

    [hn-jw@iZbp1gp1t778obaz5m8vk8Z ik]$ 
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z ik]$ unzip elasticsearch-analysis-ik-7.6.2.zip

IK配置成功后还是要重启一下，否则不生效
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z ik]$ docker stop es7.6.2
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z ik]$ docker rm es7.6.2
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z ik]$ 
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z ik]$ 
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z ik]$ docker run -p 9200:9200 -p 9300:9300 --name es7.6.2 -e "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms512m -Xmx1024m" -v /home/hn_home/docker/elasticsearch/plugins:/usr/share/elasticsearch/plugins -v /home/hn_home/docker/elasticsearch/data:/usr/share/elasticsearch/data -v /home/hn_home/docker/elasticsearch/logs:/usr/share/elasticsearch/logs -v /home/hn_home/docker/elasticsearch/config:/usr/share/elasticsearch/config -d elasticsearch:7.6.2
    a0f0592bc2f3f4467251437a32737d76b2cd0f4a0034cf0ea7197de1c16f8632
    [hn-jw@iZbp1gp1t778obaz5m8vk8Z ik]$

### **三：docker 内Elasticsearch使用** ###

# 查看集群健康状态
    curl 127.0.0.1:9200/_cat/health?v
    # 查看节点健康状态
    curl 127.0.0.1:9200/_cat/nodes?v
    # 查看索引信息
    curl 127.0.0.1:9200/_cat/indices?v

[hn-zcsjw@iZbp1gp1t778obaz5m8vk8Z config]$  curl http://127.0.0.1:9200/
    {
      "name" : "7ab1554168d9",
      "cluster_name" : "docker-cluster",
      "cluster_uuid" : "mgb4vDWvQCWTgvkPG3TU4Q",
      "version" : {
        "number" : "7.6.2",
        "build_flavor" : "default",
        "build_type" : "docker",
        "build_hash" : "ef48eb35cf30adf4db14086e8aabd07ef6fb113f",
        "build_date" : "2020-03-26T06:34:37.794943Z",
        "build_snapshot" : false,
        "lucene_version" : "8.4.0",
        "minimum_wire_compatibility_version" : "6.8.0",
        "minimum_index_compatibility_version" : "6.0.0-beta1"
      },
      "tagline" : "You Know, for Search"
    }

Docker安装 Elasticsearch已基本完成，从中我们可以清晰感受到Docker的强大之处！

### **四：发一个挂掉后自动重启的包，指定容器内存大小的启动参数** ###

[hn-jw@iZbp1gp1t778obaz5m8vk8Z elasticsearch]$ 
    docker run --restart=on-failure:10 -d -m 2G --memory-swap 4G -p 9200:9200 \
    -p 9300:9300 --privileged=true --name es7.6.2 \
    -e "discovery.type=single-node" \
    -e ES_JAVA_OPTS="-Xms512m -Xmx1024m" \
    -v /home/hn_home/docker/elasticsearch/plugins:/usr/share/elasticsearch/plugins \
    -v /home/hn_home/docker/elasticsearch/data:/usr/share/elasticsearch/data \
    -v /home/hn_home/docker/elasticsearch/logs:/usr/share/elasticsearch/logs \
    -v /home/hn_home/docker/elasticsearch/config:/usr/share/elasticsearch/config \
    -d elasticsearch:7.6.2

# 五：课外知识 #

9300 是TCP协议端口号，ES集群之间通讯端口号

9200 端口号，暴露ES RESTful接口端口号

我们常用的Head插件都连接9200、java客户端也连：9200
