set vm.max_map_count to 262144

grep vm.max_map_count /etc/sysctl.conf
vm.max_map_count=262144

sysctl -w vm.max_map_count=262144

新建docker-compose.yml文件

docker-compose up

docker exec -it elasticsearch


http.cors.enabled: true
http.cors.allow-origin: "*"

配置daemon.json

sudo systemctl daemon-reload
sudo systemctl restart docker
sudo systemctl status docker -l

免sudo

如果还没有 docker group 就添加一个：
sudo groupadd docker

将用户加入该 group 内。然后退出并重新登录就生效啦。
sudo gpasswd -a ${USER} docker

重启 docker 服务
sudo service docker restart

切换当前会话到新 group 或者重启 X 会话
newgrp - docker

Elasticsearch提供的API来检查一下集群和节点的健康状况
http://127.0.0.1:9200/_cluster/health
http://127.0.0.1:9200/_cat/health?v
http://127.0.0.1:9200/_cat/nodes?v&pretty
curl -X GET "localhost:9200/_cat/nodes?v&pretty"

防火墙

1.防火墙状态
sudo systemctl status firewalld

接着先是看centos7的防火墙的状态，查看的命令为。
查看后，看到active(running)就意味着防火墙打开了。

2.启动防火墙

sudo systemctl start firewalld

3.关闭防火墙
sudo systemctl stop firewalld
关闭后查看是否关闭成功，如果看到inactive(dead)就意味着防火墙关闭了。
