# 3.开启时间同步
```shell
# 0.下载wget,如果没有的话
yum install wget -y
# 1.先备份
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak
# 2.下载
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
yum install -y epel-release
# 或者
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
yum install -y epel-release
# 非阿里云ECS用户会出现 Couldn't resolve host 'mirrors.cloud.aliyuncs.com' 信息,不影响使用。用户也可自行修改相关配置: eg:
sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo
# 3.清理缓存
yum clean all # 清除系统所有的yum缓存
yum makecache # 生成yum缓存
# 4.安装时间同步软件
yum install ntp -y
systemctl enable ntpd && systemctl start ntpd
timedatectl set-timezone Asia/Shanghai
hostnamectl set-hostname
# 安装界面
yum -y groups install "GNOME Desktop"
systemctl set-default multi-user.target //设置成命令模式
systemctl set-default graphical.target //设置成图形模式
