Ubuntu

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

设置密钥登录​

sudo sed -i 's/PubkeyAuthentication no/PubkeyAuthentication yes/g' /etc/ssh/sshd_config

cat /etc/ssh/sshd_config | grep PubkeyAuthentication

静态IP​

  1. 将虚拟机软件设置为桥接
  2. 查看mac的路由器的信息
  3. 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

  1. 参考CSDN
  2. 列出虚拟机:
prlctl list -a
  1. 把重复的UUID的虚拟机的UUID取消注册
prlctl unregister 14182a5e-8a9e-4bfe-94cd-ac807bb40fa4
  1. 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 /Users/lisa/Public/Linux/Ubuntu/node2.pvm/

clash代理​

设置代理​

HTTP(S)​

别名

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 >> $SHELL_FILE <<EOF
alias vpnon="export http_proxy='http://$MAC_IP:7890';export https_proxy='https://$MAC_IP:7890'"

alias vpnoff="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
