如何解决Centos7:无法安装nginx或epel
我在 RaspberryPi3b+ 上全新安装了 Centos 7。我正在尝试安装 nginx,但每种方法都遇到问题。
我所做的大部分研究都指向 installing epel
,然后安装 nginx。当我运行 yum install epel-release
时,出现错误:
No package epel-release available.
Error: Nothing to do.
一些搜索使我直接从 Fedora 找到了 wget
。我能够做到这一点。然后我成功运行了 rpm -ivh epel-release-latest-7.noarch.rpm
,然后尝试了 yum install nginx
。这给了我这么长的错误:
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. Run the command with the repository temporarily disabled
yum --disablerepo=<repoid> ...
4. Disable the repository permanently,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>
or
subscription-manager repos --disable=<repoid>
5. 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
Cannot retrieve metalink for repository: epel/armhfp. Please verify its path and try again
所以,我发现 another method 不需要 epel
。我在 /etc/yum.repos.d/nginx.repo
为 nginx 创建了一个 .repo 文件,并添加了:
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=0
enabled=1
我运行 yum repolist
并出现错误:
http://nginx.org/packages/centos/7/armhfp/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found
为了笑,我无论如何都尝试安装 nginx,但得到了一个类似于上面那个 nginx repo 失败的长错误。
最后,我尝试访问 nginx.org 并找到正确的链接并将其硬编码到 repo 文件中。那也没有用,现在我真的被困住了。
