centos7使用docker安装es(elasticsearch)

 

1、安装docker依赖（已安装可以不用安装）

?

1	yum install -y docker

　　

2、搜索镜像

?

1	docker search elasticsearch

 如果出现以下报错

?

1	Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

执行以下代码

?

1 2	systemctl daemon-reload sudo service docker restart

 

3、拉取镜像（我这里拉取的是6.6.0版本的）

?

1	docker pull elasticsearch:6.6.0

 

4、查看镜像

?

1 2 3

[root@host1 bin]# docker images REPOSITORY                TAG                 IMAGE ID            CREATED             SIZE docker.io/elasticsearch   6.6.0               752be83a5396        10 months ago

　　

 

5、启动镜像

 

先执行

echo "http.host: 0.0.0.0" >>/data/elasticsearch/config/elasticsearch.yml

 

 （我在这里使用了 -e 限制内存大小  ）

docker run --name elasticsearch -p 9200:9200 -p 9300:9300 -e discovery.type="single-node" -e ES_JAVA_OPTS="-Xms128m -Xmx256m" -v /data/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /data/elasticsearch/data:/usr/share/elasticsearch/data -v /data/elasticsearch/plugins:/usr/share/elasticsearch/plugins -d elasticsearch:6.6.0

 

 

 

docker-compose方式

version: '3'
services:
  elasticsearch:
    container_name: elas
    image: elasticsearch:6.6.0
    ports:
      - 9200:9200
      - 9300:9300
    restart: always
    network_mode: "host"
    privileged: true
    environment:
      - discovery.type=single-node
      - ES_JAVA_OPTS=-Xms128m -Xmx256m
    volumes:
      - /data/elasticsearch/config:/usr/share/elasticsearch/config
      - /data/elasticsearch/data:/usr/share/elasticsearch/data
      - /data/elasticsearch/plugins:/usr/share/elasticsearch/plugins

 

 

 

 

 

6、使用命令查看防火墙端口是否已经开放

?

1	firewall-cmd --list-port

　 如果结果中没有看到9200和9300端口，需要开放这两个端口，使用以下命令

7、开放相关端口

?

1 2	firewall-cmd --zone=public --add-port=9200/tcp --permanent firewall-cmd --zone=public --add-port=9300/tcp --permanent

 重启防火墙

?

1	firewall-cmd --reload

　　

打开谷歌浏览器访问

?

1	服务器IP：9200

出现以下内容

{
  "name" : "MKKyl86",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "ZsFLqfP9Tg6olrvJCuiqHw",
  "version" : {
    "number" : "6.6.0",
    "build_flavor" : "default",
    "build_type" : "tar",
    "build_hash" : "a9861f4",
    "build_date" : "2019-01-24T11:27:09.439740Z",
    "build_snapshot" : false,
    "lucene_version" : "7.6.0",
    "minimum_wire_compatibility_version" : "5.6.0",
    "minimum_index_compatibility_version" : "5.0.0"
  },
  "tagline" : "You Know, for Search"
}
