Docker部署es+kibana -- 操作筆記

docker 部署es+kibana

安裝elasticsearch

進入docker 官方鏡像倉庫https://hub.docker.com/，如果第一次使用，需要注冊賬號

注冊登錄后，在頁面搜索elasticsearch

搜索到后，進入頁面向下查找

#es暴露的端口很多
#es也十分耗內存
#es的數據一般需要放置到安全目錄！使用掛載

#創建網絡，可以使用已經創建的網絡
$ docker network create --driver bridge --subnet 192.168.0.0/24 --gateway 192.168.0.1 mynet
#運行es，單節點運行
[root@node1 docker]# docker run -d --name elasticsearch --net mynet -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:7.10.1
#使用查看es狀態
[root@node1 docker]# docker ps

es運行后，發現系統變得比較卡，顯然是es耗掉了絕大部分內存

#查看系統消耗，占內存65%
[root@node1 docker]# docker stats
#停止es
[root@node1 docker]# docker stats
#增加內存限制,修改配置文件 -e 環境配置修改
[root@node1 docker]# docker run -d --name elasticsearch --net mynet -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms64m -Xmx256m" elasticsearch:7.10.1

es安裝完成，現在安裝kibana

安裝kibana

到docker官方查看kibana

#docker 運行kibana,同es使用相同版本7.10.1，同樣使用mynet網絡
[root@node1 docker]# docker run -d --name kibana --net mynet -p 5601:5601 kibana:7.10.1

#新建es數據和配置目錄
[root@node1 docker]#mkdir -p /mydata/elasticsearch/{config,data}
//新建並寫入配置文件
[root@node1 docker]#echo "http.host: 0.0.0.0" >> /mydata/elasticsearch/config/elasticsearch.yml
[root@node1 elasticsearch]# ls
config  data
