Linux之系统配置
【Ubuntu】
1、将ens3改成eth0
a、打开/etc/default/grub文件,找到GRUB_CMDLINE_LINUX="" 将其改为GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"
b、执行grub-mkconfig -o /boot/grub/grub.cfg或者update-grub
c、将/etc/network/interfaces中的ens3改成eth0
d、rm -rf /etc/network/interfaces.d/*
e、grep -r "ens3" /etc/找到其他和ens3的相关配置，发现/etc/udev/rules.d/*.rules也有，需要将其改掉或者删除该文件
2、配置阿里源
/etc/apt/sources.list
阿里云deb cdrom:[Ubuntu 16.04 LTS _Xenial Xerus_ - Release amd64 (20160420.1)]/ xenial main restricted

apt-get update 更新源
更新软件包： apt-get upgrade
2、安装networkmanager,配置阿里源
apt-get install network-manager
systemctl disable networking
systemctl enable network-manager
将/etc/Networkmanager/NetworkManager.conf中的改成managed=true
rm -rf /etc/Networkmanager/system-connections/*

【centos】
1、将网卡名字改成eth0
[root@localhost ~]# ls /etc/sysconfig/network-scripts/ifcfg-ens32
[root@localhost ~]# vim /etc/sysconfig/network-scripts/ifcfg-ens32
[root@localhost ~]# mv /etc/sysconfig/network-scripts/ifcfg-ens32 /etc/sysconfig/network-scripts/ifcfg-eth0
动态DHCP获取
cat >>/etc/sysconfig/network-scripts/ifcfg-eth0<< 'EOF'
DEVICE="eth0"
BOOTPROTO="dhcp"
ONBOOT="yes"
TYPE="Ethernet"
PERSISTENT_DHCLIENT="yes"
EOF
编辑grub配置文件/etc/sysconfig/grub,在GRUB_CMDLINE_LINUX变量中添加一句”net.ifnames=0 biosdevname=0“
重新生成grub配置并更新内核参数：
[root@localhost ~]# grub2-mkconfig -o /boot/grub2/grub.cfg
