CentOS 中使用yum出現的“UnicodeDecodeError: 'ascii' codec”問題解決方案，centos問題
問題

新裝了CentOS 6.5系統，打算使用yum安裝程式是出現了如下錯誤：

解決方案

依次執行以下操作:

 cd /var/lib/rpm/rm -i __db.*yum clean allyum history new

centos下使用yum 安裝mplayer出現下面錯誤，僅列出最後錯，協助

出現的問題就是這些列出來的so庫檔案太舊，
mplayer依賴更新的庫檔案，
解決方案有的，但是很麻煩，
需要手動下載這些庫檔案然後複製到相應的地址再建立串連，
或者是下載包含這些庫檔案的rpm包手動安裝，
不過後者可能因為其他依賴關係不滿足而失敗，
最好的方法就是你用fedora吧…
fedora和centos都是redhat的兒子，除了軟體源fedora的比較新，軟體比較多，其他都一樣
centos是專為伺服器而生的，所以為了追求穩定和安全一般軟體和其他東西都不是最新的，真的不適合用作個人桌面系統，同樣wps和sogouIMEcentos也無法安裝
mplayer是源於第三方yum源的，所以centos會滿足不了依賴關係而無法安裝，想想看那個伺服器會裝mplayer的

所以真心建議換fedora，既可以學習centos的命令，伺服器搭建等centos能夠完成的東西，也能夠安裝最新的針對案頭使用者的軟體～比如WPS，mplayer等等辦公娛樂軟體
 
centos65 使用yum 安裝mysql的問題

解決方案如下：

# cd /etc/

#ls

找到yum.repos.d這個目錄，裡面有個檔案zl.repo（你的機器裡也許不是這個名字，名稱應該是自訂的）,vi 編譯一下裡面的地址baseurl=centos.ustc.edu.cn/centos/5/os/i386/

然後#yum clean all
