**1. 通过`docker pull elasticsearch:5.6.8`拉取镜像到本地**

**2. 先启动Elasticsearch（以下简称“ES”）用于拷贝主机中的配置文件和数据文件**

#### Mac ####

docker run -p 9250:9200 \
    -p 9350:9300 \
    -e ES_JAVA_OPTS="-Xms512m -Xmx1024m" \
    --name elasticsearch5 \
    -d elasticsearch:5.6.8

#### Linux ####

sudo docker run -p 9250:9200 \
    -p 9350:9300 \
    -e ES_JAVA_OPTS="-Xms512m -Xmx1024m" \
    --name elasticsearch5 \
    -d elasticsearch:5.6.8

当ES启动成功后CLI将输出以下内容：  
![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2tpZGFfeXVhbg_size_16_color_FFFFFF_t_70][]

**3. 通过Docker cp的命令行将主机的内容拷贝到宿主机**

#### Mac ####

docker cp \
    elasticsearch5:/usr/share/elasticsearch/config/ \
    /Users/yuanzhenhui/Documents/docker_data/elasticsearch5

docker cp \
    elasticsearch5:/usr/share/elasticsearch/data/ \
    /Users/yuanzhenhui/Documents/docker_data/elasticsearch5

#### Linux ####

sudo docker cp \
    elasticsearch5:/usr/share/elasticsearch/config \
    /home/yzh/Documents/Installed/docker/docker_repo/elasticsearch5/config

sudo docker cp \
    elasticsearch5:/usr/share/elasticsearch/data \
    /home/yzh/Documents/Installed/docker/docker_repo/elasticsearch5/data

**4. 编辑配置文件**

#### Mac ####

打开 /Users/yuanzhenhui/Documents/docker\_data/elasticsearch5/config 找到elasticsearch.yml文件。  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2tpZGFfeXVhbg_size_16_color_FFFFFF_t_70 1]  
写上以上配置信息后保存即可。

#### Linux ####

sudo vim 
    /home/yzh/Documents/Installed/docker/docker_repo/elasticsearch5/config/elasticsearch.yml

同理，也填上如上图所示的配置信息后保存即可。

**5. 将原来执行的镜像删除并执行新的命令行**

#### Mac ####

docker run -p 9250:9200 \
    -p 9350:9300 \
    -e ES_JAVA_OPTS="-Xms512m -Xmx1024m" \
    -v /Users/yuanzhenhui/Documents/docker_data/elasticsearch5/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml \
    -v /Users/yuanzhenhui/Documents/docker_data/elasticsearch5/data:/usr/share/elasticsearch/data \
    --restart=always \
    --name elasticsearch5 \
    -d elasticsearch:5.6.8

#### Linux ####

sudo docker run -p 9250:9200 \
    -p 9350:9300 \
    -e ES_JAVA_OPTS="-Xms512m -Xmx1024m" \
    -v /home/yzh/Documents/Installed/docker/docker_repo/elasticsearch5/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml \
    -v /home/yzh/Documents/Installed/docker/docker_repo/elasticsearch5/data:/usr/share/elasticsearch/data \
    --restart=always \
    --name elasticsearch5 \
    -d elasticsearch:5.6.8

若ES启动成功可以看到以下输出：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2tpZGFfeXVhbg_size_16_color_FFFFFF_t_70 2]  
从上图可以看出ES的配置信息已经生效。

**6. 安装分词插件**

通过命令行Docker cp将分词压缩包上传到主机

#### Mac ####

直接在本地解压插件zip包，然后通过cp命令上传文件夹到Docker镜像中，当然了如果解压后的文件夹不叫analysis-ik的时候还需要重命名文件夹先。

docker cp \
    /Users/yuanzhenhui/Downloads/analysis-ik \
    elasticsearch5:/usr/share/elasticsearch/plugins

#### Linux ####

sudo docker cp \
    /home/yzh/Downloads/elasticsearch-analysis-ik-5.6.8.zip \
    elasticsearch5:/usr/share/elasticsearch/plugins

上传之后通过CLI进入主机，进入plugins目录对刚刚上传的zip文件进行解压。

cd /usr/share/elasticsearch/plugins

unzip elasticsearch-analysis-ik-5.6.8.zip -d analysis-ik
    cd analysis-ik/elasticsearch
    mv * ../
    cd ..
    rm -rf elasticsearch
    cd ..
    rm -rf elastic*

之后再重启ES

当看到上面红框的内容时表示分词插件已经安装成功，同理其他插件都是通过以上的方式进行安装。

**7. Elasticsearch7的安装**  
其实ES7的安装模式跟ES5基本一致，这里就不详说了，下面给出Mac和Linux部署脚本。

**7.1 下载Elasticsearch7的镜像之后就先启动一下**

#### Mac ####

docker run -p 9270:9200 \
    -p 9370:9300 \
    -e ES_JAVA_OPTS="-Xms512m -Xmx1024m" \
    --name elasticsearch7 \
    -d elasticsearch:7.5.2

#### Linux ####

sudo docker run -p 9270:9200 \
    -p 9370:9300 \
    -e ES_JAVA_OPTS="-Xms512m -Xmx1024m" \
    --name elasticsearch7 \
    -d elasticsearch:7.5.2

**7.2 拷贝主机中的配置文件和数据文件到宿主机**

#### Mac ####

docker cp \
    elasticsearch7:/usr/share/elasticsearch/config \
    /Users/yuanzhenhui/Documents/docker_data/elasticsearch7

docker cp \
    elasticsearch7:/usr/share/elasticsearch/data \
    /Users/yuanzhenhui/Documents/docker_data/elasticsearch7

#### Linux ####

sudo docker cp \
    elasticsearch7:/usr/share/elasticsearch/config \
    /home/yzh/Documents/Installed/docker/docker_repo/elasticsearch7/config

sudo docker cp \
    elasticsearch7:/usr/share/elasticsearch/data \
    /home/yzh/Documents/Installed/docker/docker_repo/elasticsearch7/data

**7.3 修改ES中的配置信息以达到调优的效果，其中包含elasticsearch.yml和jvm.options两个文件**

#### Mac ####

**MacOS的情况下可以到相应路径下的对应文件按需修改即可**

![在这里插入图片描述][20210218101810714.png]

#### Linux ####

sudo vim /home/yzh/Documents/Installed/docker/docker_repo/elasticsearch7/config/elasticsearch.yml

sudo vim /home/yzh/Documents/Installed/docker/docker_repo/elasticsearch7/config/jvm.options

**7.4 最终启动执行脚本运行**

#### Mac ####

docker run -p 9270:9200 \
    -p 9370:9300 \
    -v /Users/yuanzhenhui/Documents/docker_data/elasticsearch7/config:/usr/share/elasticsearch/config \
    -v /Users/yuanzhenhui/Documents/docker_data/elasticsearch7/data:/usr/share/elasticsearch/data \
    --restart=always \
    --name elasticsearch7 \
    -d elasticsearch:7.5.2

#### Linux ####

sudo docker run -p 9270:9200 \
    -p 9370:9300 \
    -v /home/yzh/Documents/Installed/docker/docker_repo/elasticsearch7/config:/usr/share/elasticsearch/config \
    -v /home/yzh/Documents/Installed/docker/docker_repo/elasticsearch7/data:/usr/share/elasticsearch/data \
    --restart=always \
    --name elasticsearch7 \
    -d elasticsearch:7.5.2

若启动的过程中碰到过下面的错误：

ERROR: [1] bootstrap checks failed
    [1]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured

这个时候只需要修改elasticsearch.yml在里面添加

cluster.initial_master_nodes: ["node-1"]

指定保留一个master节点即可解决。
