ES启动异常：max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

现象

ES启动时出现异常

bin/elasticsearch
 
max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]      

原因分析

系统虚拟内存默认最大映射数为65530，无法满足ES系统要求，需要调整为262144以上。

#修改文件
sudo vim /etc/sysctl.conf
 
#添加参数
...
vm.max_map_count =      

sysctl -p
