ElasticSearch启动报错，bootstrap checks failed

ERROR: [3] bootstrap checks failed
[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
[2]: memory locking requested for elasticsearch process but memory is not locked
[3]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

 

处理

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

 

编辑 /etc/sysctl.conf，追加以下内容：
vm.max_map_count=655360
保存后，执行：

sysctl -p

重新启动，成功。

bin/elasticsearch -d 或者bin/elasticsearch &
