想给
eth2添加一个4网段的ip，/etc/sysconfig/network-scripts/ifcfg-eth2显示如下DEVICE="eth2"
BOOTPROTO=none
NM_CONTROLLED="yes"
ONBOOT=yes
TYPE="Ethernet"
UUID="3ef520ec-fd6e-4f41-9e79-d7f1d63967b2"
HWADDR="2C:76:8A:B0:38:D2"
IPADDR="192.168.1.241"
PREFIX=24
DEFROUTE=yes
IPV4_FALURE_FATAL=yes
IPV6INIT=no
NAME="System eth2"cp -p ifcfg-eth2 ifcfg-eth2:1把IP改为192.168.4.241，
service network restart后ifconfig不显示eth2:1，后来发现是NM_CONTROLLED=yes的问题，当 NM_CONTROLLED 设为 yes 并有安装运行 NetworkManager 服务。若编辑了网卡配置文件，需要先重启 NetworkManager 再重启 network 服务。解决方法：
改为
NM_CONTROLLED=no，service network restart，ifconfig后显示eth2:1最终
/etc/sysconfig/network-scripts/ifcfg-eth2:1显示如下DEVICE="eth2:1"
BOOTPROTO=none
NM_CONTROLLED="no"
ONBOOT=yes
TYPE="Ethernet"
UUID="3ef520ec-fd6e-4f41-9e79-d7f1d63967b2"
HWADDR="2C:76:8A:B0:38:D2"
IPADDR="192.168.4.241"
PREFIX=24
DEFROUTE=yes
IPV4_FALURE_FATAL=yes
IPV6INIT=no
NAME="System eth2:1"NetworkManager 检查命令：
chkconfig --list NetworkManager
