原因
![max file descriptors [65535] for elasticsearch process is too low,【已解决】_bash_02](https://file.cfanz.cn/uploads/png/2022/08/12/16/ScI0U1MPD6.png "在这里插入图片描述")
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
