emcc刷写系统后进系统第一步

第一步

01.系统原因吧，反正一直用的iptables-legacy会导致docker等安装不好，

使用：update-alternatives –set iptables /usr/sbin/iptables-legacy

02.apt源替换

vim  /etc/apt/sources.list

deb http://mirrors.aliyun.com/debian/ buster main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ buster main non-free contrib
deb http://mirrors.aliyun.com/debian-security buster/updates main
deb-src http://mirrors.aliyun.com/debian-security buster/updates main
deb http://mirrors.aliyun.com/debian/ buster-updates main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ buster-updates main non-free contrib
deb http://mirrors.aliyun.com/debian/ buster-backports main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ buster-backports main non-free contrib

apt update

错误提示：

W: GPG error: http://mirrors.aliyun.com/debian buster-backports InRelease: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY 0E98404D386FA1D9 NO_PUBKEY 6ED0E7B82643E131

apt-get install sudo gnupg -y

开终端并运行以下命令，将缺少的公钥添加到你的系统中：

sudo apt-key adv –keyserver keyserver.ubuntu.com –recv-keys 0E98404D386FA1D9 6ED0E7B82643E131

再次update就没有错误了

#第二部

现在开始挂载磁盘

vim /etc/fstab 添加

/dev/sda1 /www ext4 defaults 0 0

/dev/sda2 /data ext4 defaults 0 0
