有时，我们可能需要在系统上安装一定的程序包，以符合某个要求。
在本文中，我们将在Centos&Rhel 7中使用Yum Package Manager将如何安装特定版本的软件包。
首先，我们需要了解特定包的可用版本。
检查可用版本
以root身份登录并在下面运行该命令
# yum --showduplicates list
在此示例中，我们将列出已启用RHEL 7系统的已启用存储库中的SAMBA的可用版本。
yum --showduplicates list samba
示例输出
Loaded plugins: amazon-id, rhui-lb, search-disabled-repos Available Packages samba.x86_64 4.1.1-31.el7 rhui-REGION-rhel-server-releases samba.x86_64 4.1.1-33.el7_0 rhui-REGION-rhel-server-releases samba.x86_64 4.1.1-35.el7_0 rhui-REGION-rhel-server-releases samba.x86_64 4.1.1-37.el7_0 rhui-REGION-rhel-server-releases samba.x86_64 4.1.1-38.el7_0 rhui-REGION-rhel-server-releases samba.x86_64 4.1.12-21.el7_1 rhui-REGION-rhel-server-releases samba.x86_64 4.1.12-23.el7_1 rhui-REGION-rhel-server-releases samba.x86_64 4.1.12-24.el7_1 rhui-REGION-rhel-server-releases samba.x86_64 4.2.3-10.el7 rhui-REGION-rhel-server-releases samba.x86_64 4.2.3-11.el7_2 rhui-REGION-rhel-server-releases samba.x86_64 4.2.3-12.el7_2 rhui-REGION-rhel-server-releases samba.x86_64 4.2.10-6.el7_2 rhui-REGION-rhel-server-releases samba.x86_64 4.2.10-6.2.el7_2 rhui-REGION-rhel-server-releases samba.x86_64 4.2.10-7.el7_2 rhui-REGION-rhel-server-releases samba.x86_64 4.4.4-9.el7 rhui-REGION-rhel-server-releases samba.x86_64 4.4.4-12.el7_3 rhui-REGION-rhel-server-releases samba.x86_64 4.4.4-13.el7_3 rhui-REGION-rhel-server-releases samba.x86_64 4.4.4-14.el7_3 rhui-REGION-rhel-server-releases samba.x86_64 4.6.2-8.el7 rhui-REGION-rhel-server-releases samba.x86_64 4.6.2-10.el7_4 rhui-REGION-rhel-server-releases samba.x86_64 4.6.2-11.el7_4 rhui-REGION-rhel-server-releases samba.x86_64 4.6.2-12.el7_4 rhui-REGION-rhel-server-releases
由于yum使用用于处理包的RPM包管理器，因此包名基于RPM包标签格式。
在上面的示例中，第一列表示包名称和IT的体系结构，第二列显示包的版本。
由于我们还注意到，最新的包是位于列表底部的包。
在这种情况下，Samba-4.6.2-12是最新的包。
安装特定版本的包
现在我们可以继续并安装任何版本的Samba包。
为此，运行我们将在最后申请包的版本。
IE
yum install <packagename> <version>
要根据早期显示的输出，请安装最新版本为4.6.2-12，请运行以下命令
yum install samba-4.6.2-12
如果我们想要更具体，我们可以包含如图所示的版本版本
yum install samba-4.6.2-12.el7_4
