7Docker搭建es和kibana

一、安装es

1.拉取镜像

sudo docker pull elasticsearch:7.12.0

 elasticsearch:7.12.0:我安装的版本是7.12.0，可以根据实际的情况安装

创建docker容器挂在的目录：

sudo mkdir -p /opt/elasticsearch/config
sudo mkdir -p /opt/elasticsearch/data
sudo mkdir -p /opt/elasticsearch/plugins

配置文件:

echo “http.host: 0.0.0.0″ >> /opt/elasticsearch/config/elasticsearch.yml

创建容器:

sudo docker run --name elasticsearch -p 9200:9200  -p 9300:9300 
-e "discovery.type=single-node" 
-e ES_JAVA_OPTS="-Xms84m -Xmx512m" 
-v /rda/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml 
-v /rda/elasticsearch/data:/usr/share/elasticsearch/data 
-v /rda/elasticsearch/plugins:/usr/share/elasticsearch/plugins 
-d elasticsearch:7.12.0

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

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

可能会出现的安装异常

异常一：文件夹未设置所有用户读写执行权限，处理：sudo chmod -R 777 /opt/elasticsearch/

异常二：echo “http.host:0.0.0.0” ==》echo “http.host: 0.0.0.0”；“：”后面有个空格！

异常三：因虚拟内存太少导致，处理：sudo sysctl -w vm.max_map_count=262144

二、安装kibana

拉取镜像

docker pull kibana

1、mkdir -p /mydata/elasticsearch/kibana/config/
2、vim  /mydata/elasticsearch/kibana/config/kibana.yml
配置以下内容：
server.name: kibana
server.host: "0"
elasticsearch.hosts: [ "http://192.168.170.132:9200" ]
xpack.monitoring.ui.container.elasticsearch.enabled: true
(192.168.170.132为自己的虚拟机ip地址，根据自己的地址进行修改。）
3、docker run -d   --name=kibana   --restart=always   -p 5601:5601   -v /mydata/elasticsearch/kibana/config/kibana.yml:/usr/share/kibana/config/kibana.yml   kibana:7.4.2
