CentOS7中安裝Snapd具體步驟
CentOS 7中如何安裝Snapd？本篇文章為大家分享一下CentOS 7安裝Snapd具體步驟，有需要的小伙伴可以參考一下。
1、首先安裝COPR插件和EPEL，通過(guò)添加epel存儲(chǔ)庫(kù)并安裝copr yum插件來(lái)啟動(dòng)安裝，運(yùn)行如下命令：
sudo yum install epel-release
sudo yum install yum-plugin-copr
2、然后添加repo：
sudo yum copr enable ngompa/snapcore-el7
3、添加存儲(chǔ)庫(kù)后，安裝snapd軟件包，運(yùn)行以下命令：
sudo yum -y install snapd
4、等待安裝完成后啟用snapd socket：
sudo systemctl enable --now snapd.socket
