Elasticsearch安装报错：max size virtual memory is too low, increase to [unlimited]

ERROR: [1] bootstrap checks failed
[1]: max size virtual memory [326850314240] for user [user] is too low, increase to [unlimited]

按照网上的教程，在/etc/security/limits.conf中添加一下指令：

* hard memlock unlimited
* soft memlock unlimited
* hard nofile 65536
* soft nofile 65536
* - as unlimited

但还是没有效果，请问是什么原因呢？求指导！
