CentOS7.3yum安裝MariaDB報錯[Errno 256]

min other 數據 generate mir generated rim true 配置

在yum安裝MariaDB時出現下面這個錯誤提示,然後著手排查,先檢查了/etc/yum.repo.d/下的配置文件,沒有錯誤。

failure: repodata/repomd.xml from mariadb: [Errno 256] No more mirrors to try.
http://yum.mariadb.org/10.3/centos7-amd64/repodata/repomd.xml: [Errno 14] curl#6 - "Could not resolve host: yum.mariadb.org; 未知的錯誤"

我這個是雲主機,剛想安裝LNMP環境。我清理了yum緩存,重新生成緩存,結果也還沒解決,還是一樣顯示上面錯誤。

然後,我又重新看了錯誤提示信息,看到下面字樣,我就感覺是DNS解析問題了。

Trying other mirror.

查看 /etc/resolv.conf,顯示為空,暈了,明明之前配置好了的,難怪yum出問題。然後修改為如下

[root@SERVER1 yum.repos.d]# cat /etc/resolv.conf 
# Generated by NetworkManager
nameserver 223.5.5.5
nameserver 8.8.8.8

清理緩存,重新生成緩存,已正常,問題已經解決
