配置静态IP
^^^^^^^^^^^^^^^
临时
-----------------

.. code-block:: shell

  # 1. 添加临时IP（重启网卡/机器失效）
  ip addr add 192.168.1.100/24 dev eth0
  # 2. 添加默认路由（所有跨网段流量走网关）
  ip route add default via 192.168.1.1 dev eth0
  # 先备份原有配置（可选）
  cp /etc/resolv.conf /etc/resolv.conf.bak
  # 写入DNS服务器
  echo "nameserver 114.114.114.114" > /etc/resolv.conf
  # 可选：再加一个备用DNS
  echo "nameserver 8.8.8.8" >> /etc/resolv.conf

永久
