将   gateway 108.181.24.14 这行注释掉后再试试
因为不能直接设置2个网关

aru

如果注释掉重启网络没报错，那么将相关部分改一下

iface eth0 inet dhcp
auto eth1
iface eth1 inet static
  address 104.149.141.131

  post-up route add default gw 104.149.141.130 metric 1
  pre-down route del default gw 104.149.141.130

  
auto eth1:1
iface eth1:1 inet static
  address 108.181.24.15
  netmask 255.255.255.254
  post-up route add default gw 108.181.24.14 metric 2
  pre-down route del default gw 108.181.24.14

删除或者注接还是报错
