cd /etc/sysconfig/network-scripts/
mv ifcfg-ens33 ifcfg-eth0
mv ifcfg-ens34 ifcfg-eth1
2. 修改網卡內容
cat > ifcfg-eth0<<END TYPE=Ethernet BOOTPROTO=none DEFROUTE=yes IPV4_FAILURE_FATAL=no NAME=eth0 DEVICE=eth0 ONBOOT=yes IPADDR=10.0.0.201 PREFIX=24 GATEWAY=10.0.0.254 DNS1=223.5.5.5 DNS2=223.6.6.6 END cat >ifcfg-eth1<<END TYPE=Ethernet BOOTPROTO=none DEFROUTE=yes IPV4_FAILURE_FATAL=no NAME=eth1 DEVICE=eth1 ONBOOT=yes IPADDR=172.16.1.200 PREFIX=24 END
3. 修改並生成grub配置
[root@CentOS7 network-scripts]# vim /etc/sysconfig/grub GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR="$(sed ‘s, release .*$,,g‘ /etc/system-release)" GRUB_DEFAULT=saved GRUB_DISABLE_SUBMENU=true GRUB_TERMINAL_OUTPUT="console" GRUB_CMDLINE_LINUX="rhgb net.ifnames=0 biosdevname=0 quiet" GRUB_DISABLE_RECOVERY="true" [root@CentOS7 network-scripts]#
4. 生成grub啟動菜單
[root@CentOS7 network-scripts]# grub2-mkconfig -o /boot/grub2/grub.cfg Generating grub configuration file ... Found linux image: /boot/vmlinuz-3.10.0-327.el7.x86_64 Found initrd image: /boot/initramfs-3.10.0-327.el7.x86_64.img Found linux image: /boot/vmlinuz-0-rescue-4860b79d6cd240788b962a1dbdef488d Found initrd image: /boot/initramfs-0-rescue-4860b79d6cd240788b962a1dbdef488d.img done [root@CentOS7 network-scripts]#
