Linux 配置yum源.

環境：虛擬機中安裝了RedHat ，在進行安裝mariadb的時候，出現如下錯誤。是因為yum源的問題，需要進行配置yum源。本教程是配置本地yum源。

[root@localhost yum.repos.d]# yum groups install mariadb mariadb-client -y 2 Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager
This system is not registered with an entitlement server. You can use subscription-manager to register.
There are no enabled repos.
 Run "yum repolist all" to see the repos you have.
 To enable Red Hat Subscription Management repositories:
     subscription-manager repos --enable <repo>
 To enable custom repositories:
     yum-config-manager --enable <repo>

 

選中虛擬機中的操作系統，鼠標：右鍵-->>設置

 

在彈出的“虛擬機設置” 窗口中，選擇：CD/DVD -->>設備狀態（已連接，確保打上勾即可）

 

 

在Linux的終端輸入：mount 指令，可以查看到有塊設備被加載進來了,見紅色標注，相關信息如下：

使用root賬號（切換root指令：su - root），在/mnt 目錄下創建一個目錄。

　　指令： mkdir /mnt/dvd

 

然后卸載/dev/sr0 ，然后掛在到/mnt/dvd ，進入的/mnt/dvd，就可以查看到鏡像內的文件了。

相關指令如下：

　　卸載： umount /dev/sr0

　　重新掛在: mount /dev/sr0 /mnt/dvd

　　進入dvd目錄: cd /mnt/dvd（此時也進入到鏡像文件內了）

　　查看鏡像內的文件：ls -l ( l是字母 )

　　

 

鏡像加載到Linux之后，開始配置repo文件，相關指令如下：

　　cd /etc/yum.repos.d/

　　vim  hello.repo (名字隨便起，但后綴名必須是：.repo)

　　

 

 　　hello.repo 文件內容如下：

[base]
name=base
baseurl=file:///mnt/dvd
enabled=1
gpgcheck=0

 

然后分別輸入如下指令：

　　 yum clean all

　　yum makecache

上面操作反顯的日志，說明yum源配置完成。

 

 然后再次輸入安裝指令：yum groups install mariadb mariadb-client -y  無報錯信息，marridb安裝成功。
