Hi,
I'm currently experimenting with CentOS 7 on a couple of installations.
I'm reasonably proficient with CentOS 5.x and 6.x.
I'd like to manage networking using a more traditional approach (Keep It
Simple Stupid). Here's what I tried so far, starting from a minimal install:
Install net-tools (to be able to use ifconfig).
Get rid of NetworkManager:
# yum remove NetworkManager*
Add 'net.ifnames=0' and 'biosdevname=0' to kernel boot options to name
interfaces eth0, eth1, etc.
Edit '/etc/sysconfig/network-scripts/ifcfg-eth{0,1}' like I did under
previous versions.
Eventually, edit '/etc/udev/rules.d/70-persistent-net.rules' to switch
interfaces:
# /etc/udev/rules.d/70-persistent-net.rules
#
# eth0
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", \
ATTR{address}=="00:1e:c9:42:84:7b", ATTR{type}=="1", \
KERNEL=="eth*", NAME="eth0"
# eth1
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", \
ATTR{address}=="00:30:f1:6a:2f:40", ATTR{type}=="1", \
KERNEL=="eth*", NAME="eth1"
So far, no way to bring either eth0 or eth1 up. What am I doing wrong
here? Is NetworkManager now a mandatory part of the base system? Some
other mistake somewhere else? I'm a bit puzzled here.
Cheers,
Niki
