在构builddocker映像时找不到有效的基础版repo：base / 7 / x86_64

我想build立一个基于centos 7的docker镜像，dockerfile如下

FROM centos MAINTAINER pengji [e-mail] WORKDIR /root COPY MySQL-5.6.26 /mysql RUN yum update RUN yum -y install java-1.8.0-openjdk wget httpd php php-mysqlnd /mysql/* RUN mysql_install_db --user=mysql ENV MYSQL_ROOT_PASSWORD=root ENV MYCAT_USER mycat ENV MYCAT_PASS mycat RUN wget http://mirror.bit.edu.cn/apache/tomcat/tomcat-7/v7.0.64/bin/apache-tomcat-7.0.64.tar.gz RUN tar xvf apache-tomcat-7.0.64.tar.gz -C /usr/local/ && mv /usr/local/apache-tomcat-7.0.64/ /usr/local/tomcat RUN wget http://code.taobao.org/svn/openclouddb/downloads/old/MyCat-Sever-1.2/Mycat-server-1.2-GA-linux.tar.gz RUN mkdir /usr/local/mycat && tar xvf Mycat-server-1.2-GA-linux.tar.gz -C /usr/local/mycat && useradd mycat && \ chown -R mycat.mycat /usr/local/mycat && chmod a+x /usr/local/mycat/bin/* EXPOSE 8080 8066 9066 COPY /home/jipeng/dockerfiles/dataguru/java_tomcat_mysql/startup.sh /root/startup.sh RUN chmod a+x /root/startup.sh ENTRYPOINT /root/startup.sh 

然后通过命令build立

 docker build -t pengji/mycat . 

过程如下

 Sending build context to Docker daemon 317 MB Step 0 : FROM centos ---> bb3d629a7cbc Step 1 : MAINTAINER pengji [e-mail] ---> Using cache ---> cdbbb4de4d8e Step 2 : WORKDIR /root ---> Using cache ---> 6d6a40194219 Step 3 : COPY MySQL-5.6.26 /mysql ---> Using cache ---> 7cfa1ec8c6b9 Step 4 : RUN yum update ---> Running in fc44891ca20a Loaded plugins: fastestmirror, ovl One of the configured repositories failed (Unknown), and yum doesn't have enough cached data to continue. At this point the only safe thing yum can do is fail. There are a few ways to work "fix" this: 1. Contact the upstream for the repository and get them to fix the problem. 2. Reconfigure the baseurl/etc. for the repository, to point to a working upstream. This is most often useful if you are using a newer distribution release than is supported by the repository (and the packages for the previous distribution release still work). 3. Disable the repository, so yum won't use it by default. Yum will then just ignore the repository until you permanently enable it again or use --enablerepo for temporary usage: yum-config-manager --disable <repoid> 4. Configure the failing repository to be skipped, if it is unavailable. Note that yum will try to contact the repo. when it runs most commands, so will have to try and fail each time (and thus. yum will be be much slower). If it is a very temporary problem though, this is often a nice compromise: yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true 

无法find有效的baseurl回购：base / 7 / x86_64

我怎么解决这个问题？ 谢谢。

也许你设置http_proxy和你的代理服务器没有得到。 取消设置http_proxy
