二、解决办法

产生这个问题的原因是因为ES的安全机制问题，解决办法如下所示（注意：ES禁止Linux使用root用户启动,因此必须使用非root用户启动）：

新增内容

vi /etc/security/limits.conf

然后

xxx(你的非root用户名) soft nofile 65536
xxx(你的非root用户名) hard nofile 65536
xxx(你的非root用户名) soft nproc 4096
xxx(你的非root用户名) hard nproc 4096

修改内容

cd /etc/security/limits.d

然后

##这两行是原本的内容
*          soft    nproc     4096
root       soft    nproc     unlimited

## 修改
#将*号改成用户名
xxx(你的非root用户名)   soft    nproc     4096
root       soft    nproc     unlimited

添加内容

vi /etc/sysctl.conf 

然后在文末添加如下内容

vm.max_map_count = 655360

保存退出以后再在 root用户状态下 执行一下内容:

sysctl -p

接下来切换到非root用户就可以启动了
