Debian系统更新源及安装inxi

Debian自带的源很多安装包打不上，非常麻烦，对于需要批量查看服务器状态的我来说很痛苦，下面是精简的debian系统更新阿里云源及安装inxi查看内存条故障位置的方法。

1. 编辑/etc/apt/sources.list，复制下面阿里源贴进去，wq保存退出。

deb https://mirrors.aliyun.com/debian-archive/debian stretch main contrib non-free
#deb https://mirrors.aliyun.com/debian-archive/debian stretch-proposed-updates main non-free contrib
deb https://mirrors.aliyun.com/debian-archive/debian stretch-backports main non-free contrib
deb https://mirrors.aliyun.com/debian-archive/debian-security stretch/updates main contrib non-free
deb-src https://mirrors.aliyun.com/debian-archive/debian stretch main contrib non-free
#deb-src https://mirrors.aliyun.com/debian-archive/debian stretch-proposed-updates main contrib non-free
deb-src https://mirrors.aliyun.com/debian-archive/debian stretch-backports main contrib non-free
deb-src https://mirrors.aliyun.com/debian-archive/debian-security stretch/updates main contrib non-free

2. 更新阿里云源

sudo apt-get update

3. 安装inxi

apt install inxi -y

4. 输入inxi就可以看到内存条状态了，可以精准定位到故障内存条物理位置。

5. 如图所示，我就知道哪个槽位的内存条有故障需要替换了。
