elasticsearch 问题

elasticsearch 的端口默认绑定到 127.0.0.1 上,对外开放 http 端口就配置 http.host,对外开放 tcp 端口就配置 network.host

[1]: max file descriptors [65535] for elasticsearch process is too low, increase to at least [65536]
编辑 /etc/security/limits.conf,追加以下内容;
* soft nofile 65536
* hard nofile 65536
此文件修改后需要重新登录用户,才会生效

[2]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
编辑 /etc/sysctl.conf,追加以下内容:
vm.max_map_count=655360
保存后,执行:

sysctl -p

curl 'localhost:9200/_cat/indices?v'
