1、yum install
[root@localhost yum.repos.d]# yum install -y yum-utils device-mapper-persistent-data lvm2
2、rpm -qa查詢安裝
[root@localhost yum.repos.d]# rpm -qa|grep device-mapper-persistent-data
device-mapper-persistent-data-0.8.5-2.el7.x86_64
3、 rpm -ql 具體的名稱(第二步的結果做條件)，路徑如斯。
[root@localhost yum.repos.d]# rpm -ql device-mapper-persistent-data-0.8.5-2.el7.x86_64
