VMware安装好centos/rhel后要配置的几点（配置本地光盘yum源、修改网卡名称为eth0等）

[iyunv@localhost ~]# setenforce 0
[iyunv@localhost ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
[iyunv@localhost ~]# tar zcvf /root/redhat.repo.tgz /etc/yum.repos.d/*
[iyunv@localhost ~]# rm -rf /etc/yum.repos.d/*
下面是rhel7的光盘yum源配置
[iyunv@localhost ~]# cat > /etc/yum.repos.d/rhel7.repo <<EOF
> [rhel7-source]
> name=rhel-source
> baseurl=file:///mnt
> enabled=1
> gpgcheck=0
> EOF
下面是centos6的光盘yum源配置
[iyunv@localhost ~]# cat > /etc/yum.repos.d/centos6.repo <<EOF     
> [c6-media]
> name=CentOS-$releasever - Media
> baseurl=file:///mnt
> gpgcheck=0
> enabled=1
> EOF

[iyunv@localhost ~]# echo "/dev/sr0 /mnt iso9660 defaults 0 0"  >> /etc/fstab
[iyunv@localhost ~]# mount -a
[iyunv@localhost ~]# yum install net-tools -y
ifconfig查看网卡名称是否为eth0，不是的话修改网卡名为eth0
①编辑网卡配置文件
vi /etc/sysconfig/network-scripts/ifcfg-eno16777736
修改其中的NAME和DEVICE为eth0
NAME="eth0"
DEVICE="eth0"
②重命名网卡配置文件
mv /etc/sysconfig/network-scripts/ifcfg-eno16777736 /etc/sysconfig/network-scripts/ifcfg-eth0
③编辑grub文件
vi /etc/default/grub
在第6行末尾rhgb quiet后面添加 net.ifnames=0 biosdevname=0
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="crashkernel=auto rd.lvm.lv=rhel/root rd.lvm.lv=rhel/swap rhgb quiet net.ifnames=0 biosdevname=0"
GRUB_DISABLE_RECOVERY="true"
④重新建立grub文件
grub2-mkconfig -o /boot/grub2/grub.cfg
⑤做快照、关机、克隆。
