sudo: dnf: command not found 命令找不到,进行安装
dnf是新一代包依赖管理,取代yum是迟早的,因为yum不支持python3(当然这个不是主要原因)
使用dnf安装的时候提示:
[root@centos7 ~]# sudo dnf install MariaDB-server
sudo: dnf: command not found
安装步骤
安装epel-release依赖
yum install epel-release -y
有点讽刺,用yum来安装
yum install dnf
查看版本
[root@centos7 ~]# dnf --version
