1、ES中开启远程连接权限

进入es安装目录中config目录中 修改elasticsearch.yml 修改如下配置：

network.host: 0.0.0.0

启动ES服务出现如下错误解决方案：

ERROR: [2] bootstrap checks failed

[1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

[2]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured

解决第一个错误：

vim /etc/sysctl.conf 添加如下命令：

vm.max_map_count=655360

保存退出之后执行如下命令：sysctl -p

解决第二个错误：

vim config/elasticsearch.yml，添如下配置：

discovery.seed_hosts: ["127.0.0.1","你的外网ip"]
