Debian服务器初始化
目录
os install
有时候会出现 select and install software 等等几个小时的情况 应该是不要选择mirrors就好了 安装后再自己加
debian 系统老旧版本iso下载
https://cdimage.debian.org/cdimage/archive
这里我们发现，在默认情况下，对于此处的每个发行版，他们将所有映像保留为jigdo格式，以节省空间和下载时间。但是保留每个系列的最新版本的ISO映像。 首先在Who are we?找到我们需要的版本，这里我直接下载ISO映像，所以我选择了Debian8系列的最新版本8.10.0 选择amd64
os init
Gentoo Linux 手册 非常有学习的价值

ssh config
openssh apt-get install openssh-client openssh-server 这个要先安装 不然自启动会不成功 如何激活服务并在启动时启用或禁用服务（即系统启动时自动启动服务） # systemctl is-active ssh.service systemctl enable ssh.service # systemctl disable ssh.service echo "ssh-rsa AAAAB3NzaC you_prk_key root@ops " >> /root/.ssh/authorized_keys sed -i "s/#PubkeyAuthentication yes/PubkeyAuthentication yes/g" /etc/ssh/sshd_config sed -i "s/^PasswordAuthentication yes/PasswordAuthentication no/g" /etc/ssh/sshd_config sed -i "s/^#PasswordAuthentication yes/PasswordAuthentication no/g" /etc/ssh/sshd_config systemctl restart sshd #service sshd restart 补充 服务端 chown -R 0700 ~/.ssh chown -R 0644 ~/.ssh/authorized_keys 客户端改一下 chmod 600 id_rsa
