Run script when eth0 UP

问题

I need to run a script after the start eth0 interface in Centos 6.8

When I do it with ppp0 I put scripts here: /etc/ppp/ip-up.local and it works. How to do the same with eth0?

I tried to put scripts in difference files, checking permissions, but does not work.

Files that I tried to put scripts:

**/etc/sysconfig/network-scripts/ip-up.local
/etc/sysconfig/network-scripts/ifup-local
/sbin/ifup-pre-local
/sbin/ifup-local
/sbin/ip-up.local**

回答1:

Using NetworkManager, we can create a file /etc/NetworkManager/dispatcher.d/15-my-ip-up-local that will run the necessary scripts

#!/bin/bash
### /bin/bash /etc/NetworkManager/dispatcher.d/15-my-ip-up-local

if [ "$1" = "eth0" ] && [ "$2" = "up" ]; then
echo run my scripts in up
else
echo DO_NOTHING
fi
