 ### 创建网桥
+#### debian 系 linux
+- **在每台服务器里执行下面操作**
+- 创建网桥 incusbr
+    ```BASH
+    apt install bridge-utils
+    brctl addbr incusbr
+    ```
+
+- 修改 /etc/network/interfaces，把 eth0 相关配置改成如下网桥配置
+    ```
+    iface eth0 inet manual
+    auto incusbr
+    iface incusbr inet static
+        address ${eth0_ip}/24
+        gateway 192.168.1.254
+        bridge-ports eth0
+        bridge-stp off
+        bridge-fd 0
+        #dns-nameservers 223.5.5.5
+    # 把 ${eth0_ip} 替换成对应服务器的 eth0 网卡 ip
+    ```
+
+- 重启网络服务，**注意此操作可能会导致服务器断网**
+    ```BASH
+    systemctl restart networking
+    ```
