elasticsearch - 如何远程访问elasticsearch 5？

Question

我想远程访问我的elasticsearch版本5。
我尝试像在elassticsearch版本4中一样将这一行添加到elasticseach.yml文件中(有效):

network.bind_host: 0.0.0.0

但是，它不起作用，elasticsearch显示错误并且不起作用。

[sagemcom@localhost bin]$ ./elasticsearch

Answer 1

如果您查看错误错误说
“错误:引导检查失败
用于Elasticsearch过程的最大文件描述符[4096]可能太低，至少增加到[65536]
最大虚拟内存区域vm.max_map_count [65530]可能太低，至少增加到[262144]
“
解决此问题为
开发模式:如果您在开发模式下运行 flex 搜索，则无需设置max_map_count。只需运行如下

docker run -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:5.6.4

生产模式::如果您在生产中运行，则需要如下设置属性。
的Linux
vm.max_map_count设置应在/etc/sysctl.conf中永久设置:

grep vm.max_map_count /etc/sysctl.conf

vm.max_map_count=262144

或

sysctl -w vm.max_map_count=262144

然后从远程访问它是不同的情况。
