请问ipaddr , ip rule , ip route 这类命令怎么让它开机生效呢

icooci

用ip addr  , ip route , ip rule 等命令配置了 网卡IP地址 以及 策略路由
但是发现重启后就不见了
目前我只能把配置写在rc.local里
想请问有什么其他的方法可以保存这些配置，使他们一直存在吗

楼主看看网卡的配置文件,策略路由不清楚,其他两个都可以在网卡的配置文件里面找到
不知道楼主的linux的版本是什么,redhat系列的在/etc/sysconfig/network-scripts目录里

系统用的是 centos  在network-scripts里面写配置确实可以设置网卡IP等参数
但 路由表、 策略路由 之类的改动就没办法写在里面了

chenyx

在/etc/sysconfig/network-scripts/route-ethN里面写,没有的话自己写一个.

楼主应该google一下

1. Mandrake & Redhat have directories for pre-up and post-up scripts.
   
2. You will have to decide how much to split the files so that the routing is still correct if you manually bring an interface down.  
   
3. If that's not going to ever happen, add it to the runlevel startup scripts at an approprite position.
   
4. 
   
5. Make sure any script that runs has the last line " ip route flush cache " or you'll get stale routing info making some interesting problems.

Iproute doesn't have a functionality like this and propably won't ever have. Allthe ip * things are set by configuration scripts at the startup.

Currently this applies not only on `ip rule` but also the same behaviour you'll get with `ip routes`, etc. None of the added data are stored.

If you need to keep your configuration, you have to dig in the bootup scripts and set the values there.

Anyway, I will discuss this with other developers and maybe I'll add this to feature requests.

路由表可以写在两个地方：
1、/etc/sysconfig/network-scripts/route-ethX
$destination_net/mask via $gw_ip

2、/etc/sysconfig/static-routes
any net $destination_net/mask gw $gw_ip

ip rules这个东西看来是没戏了。

看来还是得用开机脚本  感谢楼上几位
