Linux下自動安裝gcc

第一步：執行安裝命令 yum install gcc

但是我在安裝的過程中一直報錯：
報錯內容（部分）：

第二步 清理快取：

yum clean all

yum makecache

但仍舊報錯：
Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os error was

14: PYCURL ERROR 6 - “Couldn’t resolve host ‘mirrorlist.centos.org’”

這種錯誤，是因為沒有配置/etc/resolv.conf。
解決方法：編輯resolv.conf檔案，新增：nameserver 8.8.8.8

第三步 配置檔案：vi resolv.conf

按字母i，進入插入模式，修改nameserver的值為 8.8.8.8
按Esc後，:wq儲存退出即可

第四步 執行 yum makecache 指令，等該指令結束後再執行安裝gcc指令

最後終於安裝成功啦，自己偷偷鼓個掌慶祝下
