有些時候我們選擇的Linux云服務(wù)器默認是Debian官方國外的源，使用國外的源在國內(nèi)用的時候安裝軟件速度比較慢。于是，我們一般是會切換成國內(nèi)的鏡像源的。在這里，國內(nèi)的源也有很多可以選擇，比如中科大、華為云、騰訊云、163等。

我們可以在Debian官方全球源列表中看到中國的源渠道，這里我整理8個常用的源。

當然，如果我們需要更換源的時候直接在對應(yīng)的：

/etc/apt/sources.list

文件中復(fù)制更新后再執(zhí)行升級。

apt update -y&& apt upgrade -y

這里的幾個國內(nèi)源鏡像，可以根據(jù)需要選擇使用。如果我們的服務(wù)器已經(jīng)是國內(nèi)的源就沒有必要更換。
