原因：elasticsearch自5版本之后，处于安全考虑，不允许使用root用户运行。

解决：创建一个普通用户，将elasticsearch 安装目录权限修改一下，切换至普通用户运行elasticsearch就可以了

跟系统优化参数有关。修改sysctl内核参数

sysctl -w vm.max_map_count=262144
[root@node1 ~]# echo "vm.max_map_count=262144" >> /etc/sysctl.conf
[root@node1 ~]# sysctl -p

[root@node1 ~]# vi /etc/security/limits.conf

重新启动：

启动成功。按ctrl+C退出。使用-d参数让服务在后台运行

[elk@node1 local]$ ./elasticsearch/bin/elasticsearch -d

这样就启动成功了。

注意：普通用户不能修改打开文件句柄数，切换到root用户，修改之后需要重启。
