1. 使用命令修改网卡名
cd /etc/sysconfig/network-scripts/
mv ifcfg-ens33 ifcfg-eth0
mv ifcfg-ens34 ifcfg-eth12. 修改网卡内容
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
END3. 修改并生成grub配置
[[email protected] 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"
[[email protected] network-scripts]# 4. 生成grub启动菜单
[[email protected] network-scripts]# grub2-mkconfig -o /boot/grub2/grub.cfg

done
[[email protected] network-scripts]# 5. 重启系统
reboot
6. 其他
如果是在新装的centos7机器上，那么会有好些命令没有那么可以装一些命令wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
yum install wget net-tools vim bash-completion lrzsz nmap nc tree -y
systemctl stop firewalld.service
systemctl disable firewalld.service
