二、离线部署es

• 1.找到一台联网的机器，把对应版本的镜像拉取下来

  sudo docker pull elasticsearch:7.10.1

  2.将镜像保存为本地文件

  sudo docker save elasticsearch:7.10.1 -o /data/appadmjjkj/images/es-docker-7.10.1.tar

  或 sudo docker save IMAGE ID -o /data/appadmjjkj/images/es-docker-7.10.1.tar

  3.将保存号的tar镜像文件上传到要部署的机器上，安装镜像

  sudo docker load -i es-docker-7.10.1.tar

• 二、单机部署

• 1.创建挂载目录[data:存放索引数据，plugins:存放es插件]

  sudo mkdir -p  /data/appadmjjkj/elasticsearch

  sudo mkdir -p  /data/appadmjjkj/elasticsearch/config/data

  sudo mkdir -p  /data/appadmjjkj/elasticsearch/config/plugins

  2.设置执行权限

  sudo chmod 777 /data/appadmjjkj/elasticsearch/config/data

  3.更改系统配置​

  sudo vi /etc/sysctl.conf

  ->>

  vm.max_map_count=262145

• 创建es.yml

•  sudo vi /data/appadmjjkj/elasticsearch/config/es.yml

    ->>

  cluster.name: elasticsearch-cluster   #集群名（三个节点一致）

  node.name: es-node   #节点名（每台节点不同）

  network.bind_host: 0.0.0.0

  network.publish_host: 10.30.4.49  #对外地址

  http.port: 9201 #对外端口（每台机器装一个ES则不用改）

  transport.tcp.port: 9301 #ES内部通信端口（每台机器装一个ES则不用改）

  http.max_content_length: 2000mb

  http.max_header_size: 1024k

  http.max_initial_line_length: 1024k

  http.cors.enabled: true

  http.cors.allow-origin: "*"  

  5.启动服务

  sudo docker run -it -e ES_JAVA_OPTS="-Xms2048m -Xmx2048m" \

  -e ES_MIN_MEM=128m \

  -e ES_MAX_MEM=4096m \

  -v /data/appadmjjkj/elasticsearch/config/es.yml:/usr/share/elasticsearch/config/elasticsearch.yml \

  -v /data/appadmjjkj/elasticsearch/config/data/:/usr/share/elasticsearch/data/ \

  -v /data/appadmjjkj/elasticsearch/config/plugins/:/usr/share/elasticsearch/plugins \

  -e "discovery.type=single-node" \

  -p 9201:9201 -p 9301:9301 \

  --restart=always \

  elasticsearch:7.10.1

  三、集群部署

  1.创建挂载目录[data:存放索引数据，plugins:存放es插件]

  sudo mkdir -p  /data/appadmjjkj/elasticsearch

  sudo mkdir -p  /data/appadmjjkj/elasticsearch/config/data1

  sudo mkdir -p  /data/appadmjjkj/elasticsearch/config/data2

  sudo mkdir -p  /data/appadmjjkj/elasticsearch/config/data3

  sudo mkdir -p  /data/appadmjjkj/elasticsearch/config/plugins1

  sudo mkdir -p  /data/appadmjjkj/elasticsearch/config/plugins2

  sudo mkdir -p  /data/appadmjjkj/elasticsearch/config/plugins3

  2.设置执行权限

  sudo chmod 777 /data/appadmjjkj/elasticsearch/config/data1

  sudo chmod 777 /data/appadmjjkj/elasticsearch/config/data2

  sudo chmod 777 /data/appadmjjkj/elasticsearch/config/data3

  3.更改系统配置​

  sudo vi /etc/sysctl.conf

  ->>

  vm.max_map_count=262145

  配置改完刷新

  sysctl -p

  4.data1/data2/data3 分别创建es.yml [network.publish_host:填写服务器ip]

   sudo vi /data/appadmjjkj/elasticsearch/config/es1.yml

    ->>

  cluster.name: elasticsearch-cluster   #集群名（三个节点一致）

  cluster.initial_master_nodes : es-node1 # 默认的主节点

  node.name: es-node1   #节点名（每台节点不同）

  network.bind_host: 0.0.0.0

  network.publish_host: 10.30.4.49  #对外地址

  http.port: 9201 #对外端口（每台机器装一个ES则不用改）

  transport.tcp.port: 9301 #ES内部通信端口（每台机器装一个ES则不用改）

  discovery.zen.minimum_master_nodes: 2 #主节点数/2+1,防止脑裂

  http.max_content_length: 2000mb

  http.max_header_size: 1024k

  http.max_initial_line_length: 1024k

  http.cors.enabled: true

  http.cors.allow-origin: "*"

  node.master: true

  node.data: true  

  discovery.zen.ping.unicast.hosts:  ["10.30.4.49:9301","10.30.4.49:9302","10.30.4.49:9303"]

         

  sudo vi /data/appadmjjkj/elasticsearch/config/es2.yml

      ->>

  cluster.name: elasticsearch-cluster

  node.name: es-node2

  network.bind_host: 0.0.0.0

  network.publish_host: 10.30.4.49

  http.port: 9202

  transport.tcp.port: 9302

  discovery.zen.minimum_master_nodes: 2 #主节点数/2+1,防止脑裂

  http.max_content_length: 2000mb

  http.max_header_size: 1024k

  http.max_initial_line_length: 1024k

  http.cors.enabled: true

  http.cors.allow-origin: "*"

  node.master: false#主节点

  node.data: true  

  discovery.zen.ping.unicast.hosts:  ["10.30.4.49:9301","10.30.4.49:9302","10.30.4.49:9303"]

     

  sudo vi /data/appadmjjkj/elasticsearch/config/es3.yml

  ->>

  cluster.name: elasticsearch-cluster

  node.name: es-node3

  network.bind_host: 0.0.0.0

  network.publish_host: 10.30.4.49

  http.port: 9203

  transport.tcp.port: 9303

  discovery.zen.minimum_master_nodes: 2 #主节点数/2+1,防止脑裂

  indices.query.bool.max_clause_count: 10000000

  http.max_content_length: 2000mb

  http.max_header_size: 1024k

  http.max_initial_line_length: 1024k

  http.cors.enabled: true

  http.cors.allow-origin: "*"

  node.master: false#主节点

  node.data: true  

  discovery.zen.ping.unicast.hosts:  ["10.30.4.49:9301","10.30.4.49:9302","10.30.4.49:9303"]

  5.启动服务

  # 服务1

  sudo docker run -itd -e ES_JAVA_OPTS="-Xms2048m -Xmx2048m" \

  -p 9201:9201 -p 9301:9301 \

  -e ES_MIN_MEM=128m \

  -e ES_MAX_MEM=4096m \

  -v /data/appadmjjkj/elasticsearch/config/es1.yml:/usr/share/elasticsearch/config/elasticsearch.yml \

  -v /data/appadmjjkj/elasticsearch/config/data1/:/usr/share/elasticsearch/data/ \

  -v /data/appadmjjkj/elasticsearch/config/plugins1/:/usr/share/elasticsearch/plugins \

  --restart=always \

  --name ES01 \

  elasticsearch:7.10.1

  # 服务2

  sudo docker run -it -e ES_JAVA_OPTS="-Xms2048m -Xmx2048m" \

  -p 9202:9202 -p 9302:9302 \

  -e ES_MIN_MEM=128m \

  -e ES_MAX_MEM=4096m \

  -v /data/appadmjjkj/elasticsearch/config/es2.yml:/usr/share/elasticsearch/config/elasticsearch.yml \

  -v /data/appadmjjkj/elasticsearch/config/data2/:/usr/share/elasticsearch/data/ \

  -v /data/appadmjjkj/elasticsearch/config/plugins2/:/usr/share/elasticsearch/plugins \

  --restart=always \

  --name ES02 \

  elasticsearch:7.10.1

  # 服务3

  sudo docker run -itd -e ES_JAVA_OPTS="-Xms2048m -Xmx2048m" \

  -p 9203:9203 -p 9303:9303 \

  -e ES_MIN_MEM=128m \

  -e ES_MAX_MEM=4096m \

  -v /data/appadmjjkj/elasticsearch/config/es3.yml:/usr/share/elasticsearch/config/elasticsearch.yml \

  -v /data/appadmjjkj/elasticsearch/config/data3/:/usr/share/elasticsearch/data/ \

  -v /data/appadmjjkj/elasticsearch/config/plugins1/:/usr/share/elasticsearch/plugins \

  --restart=always \

  --name ES03 \

  elasticsearch:7.10.1

  四、验证是否正常启动

sudo docker ps -a 查看容器状态

确认集群配置

curl http://127.0.0.1:9201/_cat/nodes?pretty
