我不是系統工程師（我更多的是軟體開發人員）。我正在嘗試在 CentOS 7 系統上安裝 Zabbix 代理，但發現 yum 存在以下問題（我在其他機器上完成了相同的過程，並成功）。
首先，我執行此命令來安裝軟體包：
[root@NCMRDB1_COL ~]# rpm -Uvh https://repo.zabbix.com/zabbix/6.4/rhel/7/x86_64/ zabbix-release-6.4-1.el7.noarch.rpm
Retrieving https://repo.zabbix.com/zabbix/6.4/rhel/7/x86_64/zabbix-release-6.4-1 .el7.noarch.rpm

2:zabbix-release-5.0-1.el7 ################################# [100%]
然後我執行了這個指令：
[root@NCMRDB1_COL ~]# yum clean all
Loaded plugins: fastestmirror, langpacks
Repodata is over 2 weeks old. Install yum-cron? Or run: yum makecache fast
Cleaning repos: MongoDB base extras updates zabbix zabbix-non-supported
Cleaning up list of fastest mirrors
我認為它只是從 yum 快取中刪除一些東西，但我看到一些對 Zabbix 的引用，所以我不知道這是否是一個問題......我想這可能是我在下一步。
最後我執行這個指令：
[root@NCMRDB1_COL ~]# yum install zabbix-agent2 zabbix-agent2-plugin-*
Loaded plugins: fastestmirror, langpacks
Determining fastest mirrors
Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_6 4&repo=os&infra=stock error was
12: Timeout on http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra =stock: (28, 'Resolving timed out after 30540 milliseconds')
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 find a valid baseurl for repo: base/7/x86_64
取得您可以看到的錯誤。它到底意味著什麼？我可以做什麼來修復它並正確安裝我的 zabbix 代理，就像我之前在其他機器上成功完成的那樣？我認為問題出在第2步。
謝謝
