linux6配置永久IP报错

第一步，配置并启用网上eth0

ifcfg-ethx网卡配置 文件路径，假设配置的是eth0网卡

[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0 #网卡设备名称

ONBOOT=yes #启动时是否激活 yes|no

BOOTPROTO=static #协议类型 dhcp bootp none

IPADDR=192.168.1.90 #网络IP地址

NETMASK=255.255.255.0 #网络子网地址

GATEWAY=192.168.1.1 #网关地址

BROADCAST=192.168.1.255 #广播地址

HWADDR=00:0C:29:FE:1A:09#网卡MAC地址

TYPE=Ethernet #网卡类型为以太网

:wq 保存配置

[root@localhost ~]#service network restart

发现居然报错如下，百思不得其解，只能baidu了

bringing up interface eth0 error ... device not managed by networkmanager or unavailable

解决办法：

1[root@localhost ~]#chkconfig NetworkManager off

2[root@localhost ~]#chkconfig network on

3 [root@localhost ~]#service NetworkManager stop

4 [root@localhost ~]#service network start

英文原文如下（大体意思是停掉NetworkManager，启用默认的Manager）：

================================================

1. Remove Network Manager from startup Services.

chkconfig NetworkManager off

2. Add Default Net Manager

chkconfig network on

Stop NetworkManager first

service NetworkManager stop

and then start Default Manager

service network start

or you can change it easy:

system-config-network

uncheck the box that sets the eth0 as managed by NetworkManager and set IP info from there.

system-config-services

stop and disable NetworkManager , start and enable network

you have problem because both of NetworkManager and Network using same Network driver and default network blocking access for NetworkManager. if you disable NetworkManager your problem will disappeared after restart.
