体验感不好
有些售后工程师不专业
必须确保下方的 rc-local.service 可以正常开机自启
添加路由
ip -4 route add default via 10.0.0.253 dev eth1 table 200
ip -4 rule add from 10.0.0.2 lookup 200
在 /etc/rc.local 中添加路由，用于开机自启
echo "ip -4 route add default via 10.0.0.253 dev eth1 table 200" >> /etc/rc.local
echo "ip -4 rule add from 10.0.0.2 lookup 200 " >> /etc/rc.local
sudo chmod +x /etc/rc.local
需要在第一行添加
#!/bin/sh（直接运行阿里云给的命令不行，因为有些系统之前没有 /etc/rc.local 文件）
root@qd:~# cat /etc/rc.local
#!/bin/sh
ip -4 route add default via 10.0.0.253 dev eth1 table 200
ip -4 rule add from 10.0.0.2 lookup 200
root@qd:~#
查看服务 rc-local.service 配置
有些系统中 rc-local.service 文件没有
[Install]相关内容，需要手动添加
