1.ERROR: bootstrap checks failed
[1]: max file descriptors [65535] for elasticsearch process is too low, increase to at least [65536]
原因:无法创建本地文件问题,用户最大可创建文件数太小
解决方案:
切换到root用户,编辑limits.conf配置文件, 添加类似如下内容:
[root@Aliyun ~]# vim /etc/security/limits.conf
添加如下内容:
* soft nofile 65536
* hard nofile 131072
