Linux增加永久路由的配置步骤

版本不通方法不同，根据版本找一下度娘

举例：

Adding permanent route configuration on Ubuntu

On Ubuntu, there are three ways of adding a permanent route to your Linux machine :

• You can add it to your Network Manager configuration file;
• You can edit your Netplan YAML configuration file;
• You can add your route to the “/etc/network/interfaces” file if you are using an old Ubuntu distribution.

Using Network Manager

To add a permanent route to the Network Manager, you have to navigate to the connection file located at “/etc/NetworkManager/system-connections”.

Edit your “Wired connection” file and add a “route1” property in the IPv4 part of the network configuration.

The route has to be defined as : the network IP address followed by the CIDR, next the default gateway and finally the next-hop.

In order for the changes to be applied, you can restart your network connection, and execute the “route -n” command in order to see your route.

Awesome, you have added a permanent route to your Linux server!
