redhat7最小化安装后网络的配置

kiloyp

1.使用ip addr 查看ip地址，检查ip是否生效，一安装好redhat7的时候，默认是没有配置ip地址的

1 2 3 4 5 6 7 8 9 10 11 12 13

[iyunv@xc ~]# ip addr 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN     link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00     inet 127.0.0.1/8 scope host lo        valid_lft forever preferred_lft forever     inet6 ::1/128 scope host        valid_lft forever preferred_lft forever 2: eno16777736: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000     link/ether 00:0c:29:99:33:ef brd ff:ff:ff:ff:ff:ff     inet 192.168.100.199/24 brd 192.168.100.255 scope global eno16777736        valid_lft forever preferred_lft forever     inet6 fe80::20c:29ff:fe99:33ef/64 scope link        valid_lft forever preferred_lft forever

2.查看网络配置文件，根据相应的网络设置ip地址，子网掩码，网关

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

[iyunv@xc ~]# cat /etc/sysconfig/network-scripts/ifcfg-eno16777736 HWADDR=00:0C:29:99:33:EF TYPE=Ethernet BOOTPROTO=static IPADDR=192.168.100.199 NETWORK=255.255.255.0 GATEWAY=192.168.100.254 DEFROUTE=yes PEERDNS=yes PEERROUTES=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_PEERDNS=yes IPV6_PEERROUTES=yes IPV6_FAILURE_FATAL=no NAME=eno16777736 UUID=42a295fa-f7a0-4734-ae54-57cad8866303 ONBOOT=yes

3.重启网络

1 2	/etc/init.d/network restart service network restart

4.测试连通性
