1、设置主机名称:
hostnamectl set-hostname centost7
su
2、更改ip获取方式为静态设置以及绑定主机名+ip到 /etc/hosts
vi /etc/sysconfig/network-scripts/ipcfg-ens33
TYPE="Ethernet"
BOOTPROTO="none"
IPADDR=10.1.1.10
NETMASK=255.255.255.0
DNS1=8.8.8.8
DNS2=119.29.29.29
NAME="ens33"
DEVICE="ens33"
ONBOOT="yes"
vi /etc/hosts
10.1.1.10 centos7
systemctl restart network
3、关闭防火墙和selinux
systemctl stop firewalld
systemctl disable firewalld
setenforce 0
vi /etc/selinux/config
SELINUX=disabled
4、配置公网yum源(推荐腾讯云)
百度:腾讯镜像站
https://mirrors.cloud.tencent.com/
找到 centos 点击查看
下载wget:
yum install wget -y
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.cloud.tencent.com/repo/centos7_base.repo
yum clean all
yum makecache
5、安装扩展软件(自动补全、vin编辑器、net-tools网络工具包以及ntpdate时间同步工具)
yum install bash-completion vim net-tools ntpdate -y
