环境启动踩过的坑。no route to host 、iptables: No chain/target/match by that name 等错误

本文详细介绍了如何配置Eureka注册中心避免自我注册,并解决了CentOS7下启动镜像时遇到的iptables错误,以及服务启动时因防火墙导致的noroutetohost错误。

环境启动报错:

com.netflix.discovery.shared.transport.TransportException: Cannot execute request on any known server

是因为注册中心注册了自己,可以设置自己不可以注册自己

eureka:
  environment: 
  instance:
    #注册到eurekaip地址
    hostname: 127.0.0.1
  client:
    serviceUrl:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
    #因为自己是为注册中心,不需要自己注册自己
    register-with-eureka: false
    #因为自己是为注册中心,不需要检索服务
    fetch-registry: false
  server:
    # 测试时关闭自我保护机制,保证不可用服务及时踢出
    enable-self-preservation: false
    eviction-interval-timer-in-ms: 2000  

centos7下启动镜像有时会报此错误:

iptables: No chain/target/match by that name

网上查询时因为内核没有和docker的链,需要重启docker。试了果然有用。

systemctl restart docker  重启了docker后再重新启动镜像果然好了。

服务启动报错:no route to host
是因为防火墙开启的原因,关闭防火墙就好。

好了,前面那个可能确实没有用线程 。 这里是老师说的,有线网络连接 和 4G网络线程 跑在他们各自的一套逻辑中(好像是线程?) 当web界面选择他时,他才有用,大概是 ifconfig可以看到,其他模块也会使用这个网络, 我下面给出的调试信息是有线模式切换4G模式的,帮我分析有没有线程的事情/? 或者说是怎么切换的,。 [2025-09-28 14:27:30] [ERROR] handle_4g_internet_status():9733 - [LTE]4G internet not connected [2025-09-28 14:27:31] [ERROR] ds_pack_config():978 - [DS]encrypt_key_type:0 [2025-09-28 14:27:31] [ERROR] handle_4g_internet_status():9733 - [LTE]4G internet not connected [2025-09-28 14:27:31] [ERROR] rtmp_reload():1213 - [RTMP]rtmp reload [2025-09-28 14:27:31] [ERROR] rtmp_reconnect():1182 - [RTMP]stop stream flag:0 pClient->lte_stop_flag:0 [2025-09-28 14:27:31]lte_reload():12064 - [LTE]lte_reload [2025-09-28 14:27:31]lte_reload():12304 - [LTE]reload: internet 4G enable.
