下载
docker pull elasticsearch:7.3.0
配置
mkdir -p /data/docker/elasticsearch
vim elasticsearch.yml
配置文件
cluster.name: elasticsearch-cluster
node.name: master
network.bind_host: 0.0.0.0
network.publish_host: "ip"
http.port: 9200
transport.tcp.port: 9300
http.cors.enabled: true
http.cors.allow-origin: "*"
node.master: true
node.data: true
discovery.zen.ping.unicast.hosts: ["ip:9300","ip:9301"]
运行
docker run -d -p 9200:9200 -p 9300:9300 -v /data/docker/elasticsearch/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /data/docker/elasticsearch/data:/usr/share/elasticsearch/data -v /data/docker/elasticsearch/logs:/usr/share/elasticsearch/logs --name es-master elasticsearch:7.3.0
-d 后台运行
-p 映射端口
-v 挂载本地目录,挂载配置文件
--name 容器名字
问题解决
启动时遇到两个问题，没有启动成功，下面是解决方法
docker logs 容器id //查看启动日志
Error opening log file 'logs/gc.log': Permission denied
因为挂载本地目录，本地目录又是root创建的，elasticsearch 不能用root权限运行，所以修改文件夹权限即可
sudo chmod -R 775 /data/docker/elasticsearch/
sudo chown -R 1000:1000 /data/docker/elasticsearch/
max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
jvm 内存不够需要修改系统jvm内存
vim /etc/sysctl.conf
追加配置
vm.max_map_count=655300
修改完后执行: sudo sysctl -p可以执行:more /proc/sys/vm/max_map_count验证下是否修改成功
修改完成后docker start container id重新启动容器,启动成功
