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]#
