1、禁用可预测命名规则
# vim /etc/default/grub
添加两句： net.ifnames=0 biosdevname=0
GRUB_TIMEOUT=5
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/root rd.lvm.lv=centos/swap net.ifnames=0 biosdevname=0 rhgb quiet"
GRUB_DISABLE_RECOVERY="true"
# grub2-mkconfig -o /boot/grub2/grub.cfg
Generating grub configuration file ...
Found linux image: /boot/vmlinuz-3.10.0-229.el7.x86_64
Found initrd image: /boot/initramfs-3.10.0-229.el7.x86_64.img
Found linux image: /boot/vmlinuz-0-rescue-a8ecfd39a4014521ae54ccef4ada1c67
Found initrd image: /boot/initramfs-0-rescue-a8ecfd39a4014521ae54ccef4ada1c67.img
done
2、修改网卡配置文件
# cd /etc/sysconfig/network-scripts/
# mv ifcfg-enoxxxxxx ifcfg-eth0
3、修改设备对应名称
# vim /etc/udev/rules.d/70-persistent-ipoib.rules
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:e0:17:54", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
4、重启系统即可
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
yum clean all
yum makecache
systemctl 动作 服务名.service
yum -y install net-tools
CentOS 7.0默认使用的是firewall作为防火墙，这里改为iptables防火墙。
firewall：
systemctl start firewalld.service#启动firewall
systemctl stop firewalld.service#停止firewall
systemctl disable firewalld.service#禁止firewall开机启动
