ELK环境搭建部署服务器

一、安装ElasticSearch

（1）搜索ElasticSearch

docker search elasticsearch

（2）下载镜像

docker pull elasticsearch:7.12.0

（3）创建elasticsearch及其相关目录

mkdir /usr/local/docker/elasticsearch

mkdir /usr/local/docker/elasticsearch/data

mkdir /usr/local/docker/elasticsearch/logs

mkdir /usr/local/docker/elasticsearch/plugins

（4）启动ElasticSearch

docker run \

--name elasticsearch \

-e "ES_JAVA_OPTS=-Xms1024m -Xmx1024m" \

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

-v /usr/local/docker/elasticsearch/data:/usr/share/elasticsearch/data \

-v /usr/local/docker/elasticsearch/plugins:/usr/share/elasticsearch/plugins \

--privileged \

-p 9200:9200 \

-p 9300:9300 \

-d elasticsearch:7.12.0

命令说明：

• -e "cluster.name=es-docker-cluster"：设置集群名称
• -e "http.host=0.0.0.0"：监听的地址，可以外网访问
• -e "ES_JAVA_OPTS=-Xms512m -Xmx512m"：内存大小
• -e "discovery.type=single-node"：非集群模式
• -v /usr/local/docker/elasticsearch/data:/usr/share/elasticsearch/data：挂载逻辑卷，绑定elasticsearch的数据目录
• -v /usr/local/docker/elasticsearch/logs:/usr/share/elasticsearch/logs：挂载逻辑卷，绑定elasticsearch的日志目录
• -v /usr/local/docker/elasticsearch/plugins:/usr/share/elasticsearch/plugins：挂载逻辑卷，绑定elasticsearch的插件目录
• --privileged：授予逻辑卷访问权
• --network itmentu-net ：加入一个名为itmentu-net的网络中
• -p 9200:9200：端口映射配置

启动时可能会发现服务没有启动成功

此时查看日志

docker logs
