centos7 yum fastestmirror不能使用
[root@localhost ~]# yum install lrzsz Loaded plugins: fastestmirror Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock error was 14: curl#6 - "Could not resolve host: mirrorlist.centos.org; Unknown error"
========================= ===========================
第一步：
[root@localhost ~]# vi /etc/yum/pluginconf.d/fastestmirror.conf [main] enabled=1//把1改为0 verbose=0 always_print_best_host = true socket_timeout=3 # Relative paths are relative to the cachedir (and so works for users as well # as root). hostfilepath=timedhosts.txt maxhostfileage=10 maxthreads=15 #exclude=.gov, facebook #include_only=.nl,.de,.uk,.ie
====== ======================================
第二步：
[root@localhost ~]# vi /etc/yum.conf [main] cachedir=/var/cache/yum/$basearch/$releasever keepcache=0 debuglevel=2 logfile=/var/log/yum.log exactarch=1 obsoletes=1 gpgcheck=1 plugins=1//将plugins的值修改为0 installonly_limit=5 bugtracker_url=http://bugs.centos.org/set_project.php?project_id=23&ref=http://bugs.centos.org/bug_report_page.php?category=yum distroverpkg=centos-release # This is the default, if you make this bigger yum won't see if the metadata # is newer on the remote and so you'll "gain" the bandwidth of not having to # download the new metadata and "pay" for it by yum not having correct # information. # It is esp. important, to have correct metadata, for distributions like # Fedora which don't keep old packages around. If you don't like this checking # interupting your command line usage, it's much better to have something # manually check the metadata once an hour (yum-updatesd will do this). # metadata_expire=90m # PUT YOUR REPOS HERE OR IN separate files named file.repo # in /etc/yum.repos.d

繼續運行，出現以下錯誤
[root@localhost ~]# yum install lrzsz Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock error was 14: curl#6 - "Could not resolve host: mirrorlist.centos.org; Unknown error" 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
and distribution release than
# and distribution.packages for the previous distribution release still work)。
3. Run the command with the repository temporarily disabled
# 4. Disable the repository permanently, so yum won't use it by default. Yum will then just ignore the repository until you perman perman mmable will then just ignore the repository until you perman permanm able for temporary usage: yum-config-manager --disableor oid#c _lt );
5. Configure the failing repository to be skipped, if it is unavailable. Note that yum will try to contact the repo. when Note that yum will to contact the repo. when it runs most mandman 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# . # yum-config-manager --save --setopt=
.skip_if_unavailable=true Cannot find a valid baseurl for repo: base/7/x86_64
