ubuntu 更新和安全

  更新和安全

在此步驟中，咱們將爲服務器配置更新。

保持咱們的服務器始終保持最新和安全是很重要的。 所以，咱們首先經過運行如下命令升級系統中的全部軟件包。

sudo apt-get update
sudo apt-get upgrade

而後，咱們打開Ubuntu的無人值守安全升級。 爲此，咱們首先須要安裝必要的軟件包。    

sudo apt-get install unattended-upgrades

When you ran apt-get upgrade, where there any "not upgraded"?

Eg: Reading package lists... Done Building dependency tree Reading state information... Done 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. Looking at 0 not upgraded.

If there were ones that were not upgraded, run

apt-get dist-upgrade
