[1]: max file descriptors [65535] for elasticsearch process is too low, increase to at least [65536]
原因
解决
第一步：修改 /etc/security/limits.conf，修改到提示值即可
[root@centos7.4-64 ~]# vim /etc/security/limits.conf * hard nofile 65536
注意：如果不生效，可能和命令行的缓存有关，关闭命令行重新打开，再启动 elasticsearch
第二步：修改 /etc/sysctl.conf
添加配置：vm.max_map_count=262144，然后执行命令 sysctl -p
