[步骤] 软件源的设置 （SLES 版） （通过本地镜像版）

步骤一：加载本地镜像到系统光驱

（步骤略）

步骤二：挂载本地镜像

# mount /dev/cdrom /mnt

（补充：这里以挂载 /dev/sr1 到 /mnt 目录为例）

步骤三：添加本地镜里的软件源

3.1 添加本地镜里的软件源 （通过 zypper 命令）

# zypper ar file:/mnt/Module-Basesystem SLE15-Base
# zypper ar file:/mnt/Module-Legacy SLE15-Legacy
# zypper ar file:/mnt/Module-Development-Tools SLE15-Tools

或者：

# zypper ar -f /mnt/Module-Basesystem SLE15-Base
# zypper ar -f /mnt/Module-Legacy SLE15-Legacy
# zypper ar -f /mnt/Module-Development-Tools SLE15-Tools

（
补充：这里以将
1) /mnt/Module-Basesystem 添加到软件源并命名为 SLE15-Base
2) /mnt/Module-Legacy 添加到软件源并命名为 SLE15-Legacy
3) /mnt/Module-Development-Tools 添加到软件源并命名为 SLE15-Tools
为例
）

3.1 添加本地镜里的软件源 （通过创建配置文件）

# vim /etc/zypp/repos.d/SLE15-Base.repo

创建以下内容：

[SLE15-Base]
enabled=1
autorefresh=0
baseurl=file:/mnt/Module-Development-Tools
# vim /etc/zypp/repos.d/SLE15-Legacy.repo

创建以下内容：

[SLE15-Legacy]
enabled=1
autorefresh=0
baseurl=file:/mnt/Module-Legacy
# vim /etc/zypp/repos.d/SLE15-Tools.repo

创建以下内容：

[SLE15-Tools]
enabled=1
autorefresh=0
baseurl=file:/mnt/Module-Basesystem/

（
补充：这里以将
1) /mnt/Module-Basesystem 添加到软件源并命名为 SLE15-Base
2) /mnt/Module-Legacy 添加到软件源并命名为 SLE15-Legacy
3) /mnt/Module-Development-Tools 添加到软件源并命名为 SLE15-Tools
为例

[内容] Linux 虚拟机和物理机的区分

如果是虚拟机：

# dmidecode -s system-product-name
VMware7,1

（补充：从输出结果可以看出此为 VMware7,1 虚拟机）

或者：

# systemd-detect-virt
vmware

（补充：从输出结果可以看出此为 vmware 虚拟机）

如果是物理机：

# dmidecode -s system-product-name
PowerEdge R940

（补充：从输出结果可以看出此为 PowerEdge R940 物理机）

或者：

# systemd-detect-virt 
none

（补充：从输出结果可以看出此为物理机）
