文章目录

一、拉取镜像

• 版本号根据需要自己选择，这里以7.7.0为例

docker pull elasticsearch:7.7.0

二、创建挂载目录

1 宿主机与容器挂载映射

宿主机位置容器位置/opt/elasticsearch/config/usr/share/elasticsearch/config/opt/elasticsearch/data/usr/share/elasticsearch/data/opt/elasticsearch/plugins/usr/share/elasticsearch/plugins

2 挂载命令执行

sudomkdir -p /opt/elasticsearch/config
sudomkdir -p /opt/elasticsearch/data
sudomkdir -p /opt/elasticsearch/plugins
# 赋予权限sudochmod -R 777 /opt/elasticsearch/
# ES配置文件echo"http.host: 0.0.0.0">> /opt/elasticsearch/config/elasticsearch.yml 

三、创建容器—运行ES

sudodocker run --name elasticsearch -p 9200:9200  -p 9300:9300 \
 -e "discovery.type=single-node"\
 -e ES_JAVA_OPTS="-Xms84m -Xmx512m"\
 -v /opt/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml \
 -v /opt/elasticsearch/data:/usr/share/elasticsearch/data \
 -v /opt/elasticsearch/plugins:/usr/share/elasticsearch/plugins \
 -d elasticsearch:7.7.0

说明:

• -p 端口映射
• -e discovery.type=single-node 单点模式启动
• -e ES_JAVA_OPTS=“-Xms84m -Xmx512m”：设置启动占用的内存范围
• -v 目录挂载
• -d 后台运行

四、查看ES是否启动成功

• 打开 http://ip:9200
