docker安装ES(elasticsearch:7.4.2) 我的主页

1.拉取ES镜像本人安装的是7.4.2 可根据自己实际需求安装命令：

1	sudo docker pull elasticsearch:7.4.2

2.创建docker容器挂在的目录

sudo docker pull elasticsearch:7.4.2
mkdir -p ~/.elasticsearch/config/
mkdir -p ~/.elasticsearch/data/
echo "http.host: 0.0.0.0">>~/.elasticsearch/config/elasticsearch.yml

3.创建实例并启动ES

sudo docker run --name elasticsearch -p 9200:9200 -p 9300:9300 \
-e ES_JAVA_OPS="-Xms256m -Xmx256m" \
-v ~/.elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml \
-v ~/.elasticsearch/data:/usr/share/elasticsearch/data \
-v ~/.elasticsearch/plugins:/usr/share/elasticsearch/plugins \
-d elasticsearch:7.4.2

参数说明:

-p 9200:9200 将容器的9200端口映射到主机的9200端口;
–name elasticsearch 给当前启动的容器取名叫 elasticsearch
-v /mydata/elasticsearch/data:/usr/share/elasticsearch/data 将数据文件夹挂载到主机;
-v /mydata/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml 将配置文件挂载到主机;
-d 以后台方式运行(daemon)
-e ES_JAVA_OPS=”-Xms256m -Xmx256m” 测试时限定内存小一点

4.查看ES启动状态命令：docker ps

5.访问elasticsearch 注意关闭防火墙访问地址：http://localhost:9200/
