报错代码

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

2.错误原因：

elasticsearch用户拥有的内存权限太小，至少需要262144；

3.解决方法：
(1)切换到root用户：

su root

(2)输入命令：

sysctl -w vm.max_map_count=262144

检查修改结果：

sysctl -w vm.max_map_count=262144

(3)修改 /etc/sysctl.conf文件

vim /etc/sysctl.conf

修改内容

vm.max_map_count=262144
