篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了请求报错No route to host (Host unreachable)相关的知识，希望对你有一定的参考价值。

请求报错No route to host (Host unreachable); nested exception is java.net.NoRouteToHostException: No route to host (Host unreachable)

报错原因

请求对方机器的端口没有打开，访问的目标地址路由不可达，这个no route to host的报错是由于收到icmp路由不可达报文而导致的。
如果是linux，是iptables阻挡造成的，可以用service iptables stop关闭iptables试试

或者开通防火墙对应的端口

查询防火墙 是否开启28083端口

sudo firewall-cmd --zone=public --query-port=28083/tcp

防火墙 开启28083端口

sudo firewall-cmd --zone=public --add-port=28083/tcp --permanent

防火墙重新加载才能生效

sudo systemctl restart firewalld
或者命令
firewall-cmd --reload

查看防火墙已经开放的端口

sudo firewall-cmd --list-ports

zabbix-server报错：No route to host

前戏：

我在VM虚拟机中创建了2个liunx系统(rhel7和cent7)，一个用作zabbix服务端，另一个用作zabbix客户端。但是用服务端监控客户端时图标是红色的监控不了，报错信息为：Get value from agent failed: cannot connect to [[客户端的IP]:10050]: [113] No route to host

报警意思大致为主机无法被监听

linux版本：centos 7

zabbix版本：zabbix 3

解决方法：

（1）使用ping命令

服务端 ping 客户端地址

如果ping的通就说明网络没问题

（2）防火墙的原因

centos 7 有两种防火墙firewall和iptables，默认是用firewall作为防火墙

# service firewalld status  //查看防火墙状态

#systemctl firewalld stop  //关闭防火墙

#service firewall start  //开启防火墙

#service firewall restart  //重新开启防火墙

iptables防护墙的命令和firewall的命令差不多，把名字换一下就行

防火墙关闭之后，重启zabbix客户端

#systemctl restart zabbix-agent  //重启zabbix客户端
