Docker 安装 Elasticsearch

1. 拉取镜像：

sudo docker pull elasticsearch:8.6.2

2. 创建docker容器挂载目录：

sudo mkdir -pv /home/zonglin/elasticsearch/config
sudo mkdir -pv /home/zonglin/elasticsearch/data
sudo mkdir -pv /home/zonglin/elasticsearch/plugins

mkdir 参数说明：

  • -p, --parents 如果存在，则没有错误，根据需要创建父目录
  • -v, --verbose 为每个创建的目录打印一条消息

3. 配置文件（elasticsearch.yml）：

echo "http.host: 0.0.0.0" > /home/zonglin/elasticsearch/config/elasticsearch.yml
chmod -R 777 /home/zonglin/elasticsearch/

参数说明：

  • ">" 如果文件存在，清空文件内容并写入。如果文件不存在，创建新文件并写入。
  • -R, --recursive 递归地更改文件和目录
  • 777 可读、可写、可执行权限

4. 创建容器：

sudo docker run --name elasticsearch -p 9200:9200  -p 9300:9300 \
 --restart=always \
 -e "discovery.type=single-node" \
 -e ES_JAVA_OPTS="-Xms84m -Xmx512m" \
 -v /home/zonglin/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml \
 -v /home/zonglin/elasticsearch/data:/usr/share/elasticsearch/data \
 -v /home/zonglin/elasticsearch/plugins:/usr/share/elasticsearch/plugins \
 -d elasticsearch:8.6.2

docker run参数说明:

  • --name string 为容器分配一个名称
  • -p, --publish list 向主机发布容器的端口
  • -P, --publish-all 将所有公开的端口发布到随机端口
  • -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, --volume list 绑定挂载卷
  • -d, --detach 在后台运行容器并打印容器ID

5. 查看启动详情：

docker ps  查看是否启动
docker logs elasticsearch  启动日志查询
docker restart elasticsearch   重启
docker exec -it elasticsearch bash 进入

安装 elasticsearch-ik 分词器

elasticsearch-ik 分词器版本和 elasticsearch 版本必须一致

1. 拉取安装包

wget https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.12.0/elasticsearch-analysis-ik-7.12.0.zip

2. 创建 ik 目录

mkdir -pv /opt/elasticsearch/plugins/ik/
unzip elasticsearch-analysis-ik-7.12.0.zip # 解压到ik目录中

3.重启服务

docker restart elasticsearch

?kibana 安装

可视化界面

Elasticvue - Microsoft Edge Addons

1. 安装kibana

kibana，elasticsearch需要版本一致

wget https://artifacts.elastic.co/downloads/kibana/kibana-7.12.0-linux-x86_64.tar.gz
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.12.0-linux-x86_64.tar.gz

2. 配置kibana/config/kibana.yml

server.host: "192.168.1.102"
# 配置远程服务器地址
elasticsearch.hosts: ["http://192.168.1.102:9200"]
# 设置中文
i18n.locale: "zh-CN"
# zh-CN
/usr/local/kibana/x-pack/plugins/translations/translations/zh-CN.json

3. 启动 kibana

# kibana 不支持root用户启动
./kibana/bin/kibana --allow-root &

4. 测试连接

systemctl stop firewalld.service # 关闭防火墙
