docker下安装配置ELK

1、centos环境，利用docker拉取es和kibana的镜像

sudo docker pull elasticsearch:7.16.3

sudo docker pull kibana:7.16.3

2、free -m命令查看内存占用

3、创建挂载用目录

mkdir -p /mydata/elasticsearch/config

mkdir -p /mydata/elasticsearch/data

mkdir -p /mydata/elasticsearch/plugins

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

4、赋予data目录读写权限

chmod -R 777 /mydata/elasticsearch/

5、启动es实例：

docker run -elasticsearch -p 9200:9200 -p 9300:9300 \

-e "discovery.type=single-node" \

-e ES_JAVA_OPTS="-Xms64m -Xmx128m" \

-v /mydata/elasticsearch/config/elasticearch.yml:/usr/share/elasticsearch/config/elasticearch.yml \

-v /mydata/elasticsearch/data:/usr/share/elasticsearch/data \

-v /mydata/elasticsearch/plugins:/usr/share/elasticsearch/plugins \

-d elasticsearch:7.16.3

6、测试9200端口访问情况

查看节点相关信息：http://192.168.56.10:9200/_cat/

查看所有节点：http://192.168.56.10:9200/_cat/nodes

7、启动kibana实例：

docker run --name kibana -e ELASTICSEARCH_HOSTS=http://192.168.56.10:9200 -p 5601:5601 \

-d kibana:7.16.3

启动成功

8、ES REST API：

get /_cat/nodes: 查看所有节点

get /_cat/health: 查看es健康状态

get /_cat/master: 查看主节点

get /_cat/indices: 查看所有索引
