Cent7虚拟机安装完成后的配置

标签（空格分隔）： 系统配置

一般服务器搭建库选择Servier with GUI 环境插件勾选Compatilblity Libraries/Development Tools/Security Tools

安装完成后创建新用户

1.配置开机启动字符界面

终端输入systemctl set-default multi-user.target
systemctl set-default multi-user.target   init 3
systemctl set-default graphical.target    init 5

2.配置网卡名称 分别修改NAME、DEVICE

[root@localhost ~]# vim /etc/sysconfig/network-scripts/ifcfg-enp0s3 TYPE=Ethernet
BOOTPROTO=dhcp
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME=enp0s3
UUID=ef18e6d3-8887-4f15-9e0a-5dd1b579910d
DEVICE=enp0s3
ONBOOT=yes

[root@localhost network-scripts]# mv ifcfg-enp0s3 ifcfg-eth0

3.编辑/etc/default/grub并加入“net.ifnames=0 biosdevname=0 ”到GRUBCMDLINELINUX变量来实现的。

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 net.ifnames=0 biosdevname=0 rhgb quiet"
GRUB_DISABLE_RECOVERY="true"

4.运行grub2-mkconfig -o /boot/grub2/grub.cfg来重新生成GRUB配置并更新内核参数

[root@localhost network-scripts]# grub2-mkconfig -o /boot/grub2/grub.cfg
