#0 0.373  One of the configured repositories failed (Unknown),
#0 0.373  and yum doesn't have enough cached data to continue. At this point the only
#0 0.373  safe thing yum can do is fail. There are a few ways to work "fix" this:
#0 0.373 
#0 0.373      1. Contact the upstream for the repository and get them to fix the problem.
#0 0.373 
#0 0.373      2. Reconfigure the baseurl/etc. for the repository, to point to a working
#0 0.373         upstream. This is most often useful if you are using a newer
#0 0.373         distribution release than is supported by the repository (and the
#0 0.373         packages for the previous distribution release still work).
#0 0.373 
#0 0.373      3. Run the command with the repository temporarily disabled
#0 0.373             yum --disablerepo=<repoid> ...
#0 0.373 
#0 0.373      4. Disable the repository permanently, so yum won't use it by default. Yum
#0 0.373         will then just ignore the repository until you permanently enable it
#0 0.373         again or use --enablerepo for temporary usage:
#0 0.373 
#0 0.373             yum-config-manager --disable <repoid>
#0 0.373         or
#0 0.373             subscription-manager repos --disable=<repoid>
#0 0.373 
#0 0.373      5. Configure the failing repository to be skipped, if it is unavailable.
#0 0.373         Note that yum will try to contact the repo. when it runs most commands,
#0 0.373         so will have to try and fail each time (and thus. yum will be be much
#0 0.373         slower). If it is a very temporary problem though, this is often a nice
#0 0.373         compromise:
#0 0.373 
#0 0.373             yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true
#0 0.373 
#0 0.373 Cannot find a valid baseurl for repo: base/7/x86_64
#0 0.373 Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=container error was

昨天刚安装完成docker的时候还是可以使用的,今天再用的时候就出现这个问题了(中间服务器是否重启不太清楚) 。

最后通过以下方法解决:原因是nameserver的问题

解决步骤

  1. 修改resolv.conf文件,增加nameserver
vim /etc/resolv.conf 

nameserver 8.8.8.8
nameserver 114.114.114.114
  1. 保存后如果重启的话,还会还原的这里需要进行锁定
chattr +i /etc/resolv.conf   //resolv被锁定,即使root也不能修改
  1. 如果需要继续修改
chattr -i /etc/resolv.conf
  1. 重启network 查看是否还存在(centos8)
systemctl restart NetworkManager

推荐
简单记录下dockerfile 以及compose配置
mysql主从复制简单模式,一主一从。
扩展程序中会有需要请求外部接口获取数据的时候,如果直接在JS中写的话,会跨域,但是谷歌扩展程序支持这种情况,只需要配置一下即可。
昨天客户发现了个小BUG,文章发布使用的ueditor, 上传视频的时候当时好好的,后来怎么就是播放不了?
反爬有很多手段,字体反爬就是其中之一。之前一直都是听过,但是却没怎么在实际爬虫中遇到过,最近在一个爬虫题目网站上看到了,试了试,发现还挺麻烦,当然自己从头研究字体肯定麻烦,简单的是模块多的是,选几个就过了。
一直有跑着puppeteer在做pdf的生成,可以今天突然发现一个问题:预览与打印生成的PDF不一致,猜测可能是边距导致的,应该是没设置好... 然后当我在本地尝试的时候也发现了这个问题..要么是字符,要么是版本
功能来源于客户需求。客户有需求想把班级内所有学生的错题本生成pdf文档下载下来... 目前没有做这个功能,只有页面,还好chrome浏览器有保存pdf的功能,但是一想到这么多的学生,这么多的学科、以及这么多的参数... 还好有puppeteer
登录方式现在非常多,不过像我这种小站让用户自己注册基本是不可能的了,只能依赖现有的第三方的登录来集成,之前有集成github,不过这个太过针对性,这里准备集成QQ互联登录,慢慢记录下。
