现在启动成功了，使用浏览器访问试一下
Éteignez le pare-feu
再次访问的时候发现还是不行，这时候需要关闭防火墙
检查防火墙状态
先切换到root用户
[esyonghu@localhost elasticsearch-6.4.0]$ su root
密码：
[root@localhost elasticsearch-6.4.0]#
查看防火墙状态
[root@localhost elasticsearch-6.4.0]# firewall-cmd --state
running
[root@localhost elasticsearch-6.4.0]#
状态是running,需要关闭防火墙
执行systemctl stop firewalld.service
[root@localhost elasticsearch-6.4.0]# systemctl stop firewalld.service
再次检查防火墙状态，就是为运行了
[root@localhost elasticsearch-6.4.0]# firewall-cmd --state
not running
[root@localhost elasticsearch-6.4.0]#
