    解决方法

    在使用cmake编译时会在opencv下新建一个文件夹，我的是cudabuild
    在cudabuild文件夹下找到CMakeDownloadLog.txt

    以 **IPPICV: Download failed: 6;“Couldn’t resolve host name”**错误为例
    在CMakeDownloadLog.txt找到对应IPPICV信息

    IPPICV信息

    #do_unpack "ippicv_2019_win_intel64_20180723_general.zip" "1d222685246896fe089f88b8858e4b2f" "https://raw.githubusercontent.com/opencv/opencv_3rdparty/32e315a5b106a7b89dbed51c28f8120a48b368b4/ippicv/ippicv_2019_win_intel64_20180723_general.zip" "C:/Users/freeyu/Desktop/opencv/opencv-4.1.0/cudabuild/3rdparty/ippicv"
#cmake_download "C:/Users/freeyu/Desktop/opencv/opencv-4.1.0/sources/.cache/ippicv/1d222685246896fe089f88b8858e4b2f-ippicv_2019_win_intel64_20180723_general.zip" "https://raw.githubusercontent.com/opencv/opencv_3rdparty/32e315a5b106a7b89dbed51c28f8120a48b368b4/ippicv/ippicv_2019_win_intel64_20180723_general.zip"
    • 在IPPCV信息里找到下载路径https://raw.githubusercontent.com/opencv/opencv_3rdparty/32e315a5b106a7b89dbed51c28f8120a48b368b4/ippicv/ippicv_2019_win_intel64_20180723_general.zip
    • 打开https://ghproxy.com/，复制路径，就会下载ippicv_2019_win_intel64_20180723_general.zip
    • 在IPPCV信息里找到C:/Users/freeyu/Desktop/opencv/opencv-4.1.0/sources/.cache/ippicv/1d222685246896fe089f88b8858e4b2f-ippicv_2019_win_intel64_20180723_general.zip
    • 把下载的文件重命名为1d222685246896fe089f88b8858e4b2f-ippicv_2019_win_intel64_20180723_general.zip
    • 把重命名的文件放入C:/Users/freeyu/Desktop/opencv/opencv-4.1.0/sources/.cache/ippicv中，原来的文件直接可以查看一下是0kb，直接删掉就行

    其他问题的解决方法同理

    一个临时的解决方法是在运行 cargo 的时候加入环境变量 CARGO_HTTP_MULTIPLEXING=false。作用是取消并行下载。具体原因可参考用了镜像之后构建rustc报错。

  • 解决：ERROR RocketmqCommon-Failed to obtain the host name

     千次阅读 2022-04-21 01:23:23
    搭建rocketmq单机环境时踩坑，找不到自己的主机名对应的ip地址

    搭建rocketmq单机环境时踩坑。

    遇到问题：在使用命令

    nohup sh mqnamesrv &

    出现如下错误

    java.net.UnknownHostException: hadoop03: hadoop03: unknown error
            at java.net.InetAddress.getLocalHost(InetAddress.java:1505) 
            at org.apache.rocketmq.common.BrokerConfig.localHostName(BrokerConfig.java:201) 
            at org.apache.rocketmq.common.BrokerConfig.<init>(BrokerConfig.java:39) 
            at org.apache.rocketmq.broker.BrokerStartup.createBrokerController(BrokerStartup.java:101) 
            at org.apache.rocketmq.broker.BrokerStartup.main(BrokerStartup.java:56)
    Caused by: java.net.UnknownHostException: hadoop03: unknown error
            at java.net.Inet4AddressImpl.lookupAllHostAddr(Native Method)
            at java.net.InetAddress$2.lookupAllHostAddr(InetAddress.java:928) 
            at java.net.InetAddress.getAddressesFromNameService(InetAddress.java:1323) 
            at java.net.InetAddress.getLocalHost(InetAddress.java:1500) 
            ... 4 common frames omitted

    这是由于启动的时候找不到自己的主机名对应的ip地址而造成的，只需要让在/etc/hosts中添加如上配置，就可以了

    解决方案：

    按如下命令进行操作

    在文件中加入标红的映射。注意：在编辑过程中可能会出现权限问题，需要切换root账户

    :wq! 保存退出

    使用jps命令查看进程，看是NamesrvStartup是否启动过，如果有关闭它

    sh mqshutdown namesrv

    再次启动mqnamesrv

    nohup sh mqnamesrv &

      

     查看日志，问题解决
