Salt-ssh批量初始化机器 Debian 管理员手册

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 good

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

容器初始化

change sources

if docker

利用Dockerfile修改容器中的apt源(debian源)

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
