解决machine-id 冲突

清除现有的旧配置：

sudo rm -f /etc/machine-id
sudo rm -f /var/lib/dbus/machine-id

其中，/var/lib/dbus/machine-id 通常是到 /etc/machine-id 的一个软链接，但有些发行版会作为独立文件存在，因此建议都删除

生成新 ID：使用 systemd-machine-id-setup 工具重新生成一个新的唯一标识：

sudo systemd-machine-id-setup
cat /etc/machine-id

增加超时时间

客户机: ~/.ssh/config

Host *
  ServerAliveInterval 60
  ServerAliveCountMax 3

服务器:

cat >> /etc/ssh/sshd_config <<EOF
ClientAliveInterval 60
ClientAliveCountMax 3
EOF

sudo systemctl restart ssh

修改密码

sudo passwd root

允许Root用户登录

sudo sed -i 's/PermitRootLogin without-password/PermitRootLogin yes/g' /etc/ssh/sshd_config

sudo systemctl restart ssh

使用国内源

sudo sed -i 's/ports.ubuntu.com/mirrors.tuna.tsinghua.edu.cn/g' /etc/apt/sources.list.d/ubuntu.sources && sudo apt update && sudo apt upgrade -y

设置密钥登录

sudo sed -i 's/#PubkeyAuthentication no/PubkeyAuthentication yes/g' /etc/ssh/sshd_config
sudo sed -i 's/PubkeyAuthentication no/PubkeyAuthentication yes/g' /etc/ssh/sshd_config
cat /etc/ssh/sshd_config | grep PubkeyAuthentication
systemctl restart ssh
systemctl restart sshd

静态IP

将虚拟机软件设置为桥接
查看mac的路由器的信息
在/etc/netplan/00-installer-config.yaml或者50-cloud-init.yaml或类似名称

cp /etc/netplan/00-installer-config.yaml{,.back}
cat > /etc/netplan/00-installer-config.yaml <<EOF

克隆出现的UUID相同问题

kubernetes以UUID区分集群机器标识, 相同的UUID的虚拟机/机器不能加入集群

参考CSDN
列出虚拟机:

prlctl list -a

把重复的UUID的虚拟机的UUID取消注册

prlctl unregister node2

重新注册生成新的UUID. 在mac主机上的终端执行以下命令: 把/Users/lisa/Public/Linux/Ubuntu/master/master1.pvm/替换为你要更改的UUID虚拟机的pvm路径

prlctl register --regenerate-src-uuid ~/linux/node2.pvm

clash代理

设置代理

HTTP(S)

别名 linux:

USER_PATH="/root"
SHELL_FILE="${USER_PATH}/.bashrc"
MAC_IP="192.168.3.220"

sudo cat >> $SHELL_FILE <<EOF
alias proxy="export http_proxy='http://$MAC_IP:7890';export https_proxy='http://$MAC_IP:7890'"

alias unproxy="unset http_proxy; unset https_proxy; unset all_proxy; echo 'Unset proxy successfully'"
EOF

source $SHELL_FILE
cat $SHELL_FILE

mac:

USER_PATH="/root"
SHELL_FILE="${USER_PATH}/.bashrc"
#export SHELL_FILE="~/.zshrc"
#MAC_IP="192.168.3.220"
MAC_IP="192.168.3.220"

sudo cat >> $SHELL_FILE <<EOF
alias proxy="export http_proxy='$MAC_IP:7890';export https_proxy='$MAC_IP:7890'"

alias unproxy="unset http_proxy; unset https_proxy; unset all_proxy; echo 'Unset proxy successfully'"
EOF

source $SHELL_FILE
cat $SHELL_FILE

Clash的Tun模式与 WireGuard冲突一份参考: https://github.com/MetaCubeX/mihomo/blob/Alpha/docs/config.yaml 打开clash的配置文件config.yaml, 添加:

...
interface-name: en0
