Elastic Search Linux 安装

创建本地映射文件夹

\#1、建Elasticsearch配置文件夹
mkdir -p /mydata/elasticsearch/config
\#2、创建Elasticsearch数据文件夹
mkdir -p /mydata/elasticsearch/data
\#3、创建Elasticsearch插件文件夹（如：ik）
mkdir -p /mydata/elasticsearch/plugins
\#4、创建Elasticsearch配置文件
echo "http.host: 0.0.0.0">>/mydata/elasticsearch/config/elasticsearch.yml
\#5、赋权Elasticsearch文件夹
chmod -R 777 elasticsearch/

1、安装

docker run --name elasticsearch -p 9200:9200 -p 9300:9300 --privileged=true \
-e "discovery.type=single-node"  \
-e ES_JAVA_OPTS="-Xms128m -Xms256m"  \
-v /mydata/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml   \
-v /mydata/elasticsearch/data:/usr/share/elasticsearch/data   \
-v /mydata/elasticsearch/plugins:/usr/share/elasticsearch/plugins   \
-d elasticsearch:7.4.2

2、跟随docker自启动

docker update elasticsearch  --restart=always

1.1如果安装失败可以先pull elasticsearch x.x.x

docker pull elasticsearch:8.1.3

1.2再挂载目录

docker run -d --name elasticsearch -p 9200:9200 \
 -p 9300:9300 \
 -e "discovery.type=single-node" \
 -e ES_JAVA_OPTS="-Xms64m -Xmx128m" \
 -v /mydata/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml \
 -v /mydata/elasticsearch/data:/usr/share/elasticsearch/data \
 -v /mydata/elasticsearch/plugins:/usr/share/elasticsearch/plugins \
 -d elasticsearch:8.1.3

参数说明

--name elasticsearch：将Elasticsearch容器命名为 elasticsearch

-p 9200:9200：将容器的9200端口映射到宿主机9200端口

-p 9300:9300：将容器的9300端口映射到宿主机9300端口，目的是集群互相通信

-e "discovery.type=single-node"：单例模式

-e ES_JAVA_OPTS="-Xms64m -Xmx128m"：配置内存大小

-v /mydata/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml：将配置文件挂载到宿主机

-v /mydata/elasticsearch/data:/usr/share/elasticsearch/data：将数据文件夹挂载到宿主机

-v /mydata/elasticsearch/plugins:/usr/share/elasticsearch/plugins：将插件目录挂载到宿主机(需重启)

-d elasticsearch：后台运行容器，并返回容器ID
