系統版本:CentOS-7-x86_64-DVD-1511.iso 虛擬機配置:2C-4G-20G-NAT 系統安裝注意事項:python
在安裝時使用內核命令net.ifnames=0 biosdevname=0
可將網卡名稱改成傳統ethx的命名規則linux
如下內容引自 RHEL7/centos7修改網卡名稱爲eth0ios
根據紅帽官方文檔介紹,設備重命名的過程以下:vim
A rule in /usr/lib/udev/rules.d/60-net.rules instructs the udev helper utility,/lib/udev/rename_device,to look into all /etc/sysconfig/networkscripts/ifcfg-suffix files.If it finds an ifcfg file with a HWADDR entry matching the MAC address of an interface it renames the interface to the name given in the ifcfg file by the DEVICE directive.centos
/usr/lib/udev/rules.d/60-net.rules文件中的規則會讓udev幫助工具/lib/udev/renamedevice查看全部/etc/sysconfig/networkscripts/ifcfg-suffix文件。若是發現包含HWADDR條目的ifcfg文件與某個接口的MAC地址匹配,它會將該接口重命名爲ifcfg文件中由DEVICE指令給出的名稱。安全
根據以上介紹,進行網卡重命名:bash
1.ifconfig命令查看網卡配置網絡
[root@test01 ~]# ifconfig
enp0s9: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.56.101 netmask 255.255.255.0 broadcast 192.168.56.255

複製代碼
由此可知,網卡MAC地址爲:08:00:27:a5:04:fd編輯器
2.重命名網卡配置文件工具
# 若是沒有網卡配置文件,能夠使用如下命令添加(命令行工具NetworkManager)
[root@test01 network-scripts]# nmcli connection add type ethernet ifname enp0s9 con-name enp0s9 autoconnect yes
複製代碼
[root@test01 network-scripts]# mv ifcfg-enp0s9 ifcfg-eth0
3.修改網卡配置文件
向配置文件中添加HWADDR,DEVICE,NAME參數。
4.拷貝配置文件60-net.rules並重啓
[root@test01 network-scripts]# cp /usr/lib/udev/rules.d/60-net.rules /etc/udev/rules.d/
[root@test01 network-scripts]# shutdown -r 0
複製代碼
實際工做中無需boot和swap分區,只需一個分區便可。
在ifcfg-eth0網卡配置文件中加入GATEWAY,IPADDR,DNS1,NETMASK,依照VMware中的虛擬網絡編輯器配置。
發現沒有vim編輯器,參考https://www.jianshu.com/p/96dbc05d3df1裝了
在/etc/sysctl.conf文件中增長以下參數
net.ipv6.conf.all.disable_ipv6 = 0
