【VMware vSphere】安装配置Update Manager Download Service（UMDS）作为 vLCM 的下载存储库。
VMware vSphere Update Manager Download Service (UMDS) 是 vSphere Lifecycle Manager（vLCM） 的可选模块。我在之前文章中提到这个功能，当 vSphere 环境能够连接 Internet 时，我们可以使用 vLCM 的在线 Internet 下载源获取修补程序，当 vSphere 环境不能连接 Internet 时，您可以在您的环境中找到一台能够访问 Internet 的服务器安装 UMDS，通过配置 UMDS 下载升级、修补程序二进制文件和修补程序元数据并自动执行导出过程，最后在 vSphere Lifecycle Manager 配置 UMDS 下载存储库后即可实现与连接 Internet 在线下载库使用一样的效果。
UMDS 必须与 vSphere Lifecycle Manager 版本相同。例如，vSphere Lifecycle Manager 8.0 只能与 UMDS 8.0 配置使用，如果您使用的是新版本的 vSphere Lifecycle Manager，则 UMDS 也必须为相同的新版本。您无法升级 UMDS，您可以卸载当前版本的 UMDS，根据系统要求执行 UMDS 的全新安装，并使用之前已卸载的 UMDS 的修补程序存储。UMDS 8.0 支持修补程序撤消和通知。如果 VMware 发布的修补程序存在问题或可能存在问题，撤消修补程序后，UMDS 下载的修补程序数据会进行同步，vSphere Lifecycle Manager 那边同样会删除已撤消的修补程序。
只能在基于 Linux 的操作系统上安装 UMDS。不再支持在 Windows 计算机上安装 UMDS。UMDS 是 64 位应用程序，要求使用 64 位 Linux 系统。支持在以下 Linux 发行版上安装并使用 Update Manager Download Service (UMDS) 。通过在 Linux 上运行的 UMDS 下载修补程序时，不需要具有管理员级别访问权限。安装 UMDS 的计算机必须能够访问 Internet。
- Ubuntu 14.04
- Ubuntu 18.04
- Ubuntu 18.04 LTS
- Ubuntu 20.04 LTS
- Red Hat Enterprise Linux 7.4
- Red Hat Enterprise Linux 7.5
- Red Hat Enterprise Linux 7.7
- Red Hat Enterprise Linux 8.1
- Red Hat Enterprise Linux 8.3
- Red Hat Enterprise Linux 8.5
- Red Hat Enterprise Linux 8.6
- Red Hat Enterprise Linux 9.0
注意，使用 Red Hat Enterprise Linux 8.1 时，必须在部署了 UMDS 的系统上安装 libnsl 软件包版本 2.28 或更高版本。如果系统中不存在该软件包，UMDS 操作可能会失败，并显示以下错误：
加载共享库 libnsl.so.1 时出错: 无法打开共享对象文件: 无此类文件或目录 (Error while loading shared libraries: libnsl.so.1: cannot open shared object file: No such file or directory)。一、UMDS 安装
本次环境准了一台 Ubuntu 20.04.6 LTS 服务器，对于 Linux 服务器的安装设置可以使用标准安装即可，配置好 DNS 和 NTP。

Thank you.
Installing VMware Update Manager Download Service.
Logs would be store at /var/log/vmware/vmware-updatemgr/umds
Creating the log directory if required....
In which directory do you want to install Download service?
[/usr/local/vmware-umds]
The path "/usr/local/vmware-umds" does not exist currently. This program is
going to create it, including needed parent directories. Is this what you want?
[yes]
Let us setup some things for you...
Do you need proxy to connect to internet? [no]
One more thing...we need a storage location to store patches. Make sure you
have enough space in that location
Where do you want download service to store patches
[/var/lib/vmware-umds]
The path "/var/lib/vmware-umds" does not exist currently. This program is going
to create it, including needed parent directories. Is this what you want?
[yes]
The installation of VMware Update Manager Download Service 8.0.2 build-23319993
completed successfully. You can decide to remove this software from your system
at any time by invoking the following command:
"/usr/local/vmware-umds/vmware-uninstall-umds.pl".
Enjoy,
--the VMware team二、UMDS 配置

root@umds:~#根据获取到的 UMDS 默认配置信息，让我们来了解一下每项配置的含义和作用：
- Configured URLs 配置项里默认有四个下载源，分别对应 vLCM 配置中的修补程序下载源地址，可以使用 vmware-umds -S --remove-url 或者 vmware-umds -S --add-url 命令移除或增加一个下载地址，比如第三方OEM厂商的下载源，--url-type 指定下载源的类型，如 HOST。
- Patcch store localtion 配置项为我们安装的时候配置的 UMDS 默认修补程序下载的保存目录，可以使用 vmware-umds -S --patch-store 命令修改默认位置。
- Export store localtion 配置项是 vLCM 所使用的默认目录，可以使用 vmware-umds -S --default-export-store 命令修改这个目录，当前设置为空，后面会设置这个地方。
- Proxy Server 配置项是设置 UMDS 服务器的网络代理地址，可以使用 vmware-umds -S --proxy 命令配置一个代理地址，如 proxy-ip:port，使用 --proxy "" 地址为空来关闭代理。
- Host patch content download 配置项表示是否开启 ESXi 主机的修补程序下载，可以使用 vmware-umds -S --enable-host 或者 vmware-umds -S --disable-host 命令开启或关闭这个功能。
- Host Versions for which patch content will be downloaded 配置项表示设置需要下载的 ESXi 主机的修补程序版本，可以使用 vmware-umds -L 命令列出当前设置的所有版本，使用 vmware-umds -S --enable-host-platform 或者 vmware-umds -S --disable-host-platform 命令增加或移除要下载的修补程序版本。
根据实际需要自定义修改配置，比如，当前 vSphere 环境中没有 vSphere 6.7 和 vSphere 7.0 的主机，那么可以把配置下载的修补程序版本给移除掉，而无需浪费不必要的网络带宽和存储空间。

root@umds:~# 如果一切没有问题，我们可以使用 vmware-umds -D 命令开始下载主机修复程序，怀疑 UMDS 修补程序存储已损坏时，可以使用 vmware-umds -R 命令重新下载可能已损坏的现有更新并下载新的更新。因为下载的内容比较多或比较慢，我们可以在运行下载任务时，开始准备 WEB 服务器。通过 UMDS 下载了修补程序文件，现在需要设置一个 Export 目录并发布共享存储库。我这里使用 nginx 作为 web 服务器，直接运行 apt-get install nginx 命令安装并运行 nginx 服务。

Jun 06 14:00:37 umds systemd[1]: Started A high performance web server and a reverse proxy server.
root@umds:~#完成 nginx 安装和服务的启动，需对 nginx 配置做一些修改，配置文件 /etc/nginx/sites-enabled/default 如下所示。通过对 nginx 配置，需要重启 nginx 服务。设置 web 服务器的下载目录为 /umds ，需在 UMDS 服务器根目录创建 umds 目录。
root@umds:~# mkdir /umds
root@umds:~# vim /etc/nginx/sites-enabled/default
root@umds:~# cat /etc/nginx/sites-enabled/default | grep -v '#'
server {
listen 80 default_server;
listen [::]:80 default_server;
index index.html index.htm index.nginx-debian.html;
server_name localhost;
location / {
root /umds;
autoindex on;
autoindex_exact_size off;
autoindex_localtime on;
charset utf-8;
}
}
root@umds:~# systemctl restart nginx
root@umds:~#通过上面的配置，现在你应该能使用 UMDS 服务器的域名访问到 web 下载服务器，但是现在还没有内容，将 UMDS 的 Export 目录配置为 web 服务器下载目录 /umds ，使用 vmware-umds -S --default-export-store 命令配置目录，使用 vmware-umds -G 命令查看配置。

root@umds:~#现在访问 web 服务器应该没有任何内容，之前通过 vmware-umds -D 命令下载修补程序如果已经完成，使用 vmware-umds -E 命令开始 Export 到 /umds 目录。如果任务完成，再次访问 web 服务器，可以看到 UMDS 下载的修补程序。
三、vLCM 设置
完成对 UMDS 的安装和配置后，现在可以到 vLCM 配置指向 UMDS 存储库的下载源了。导航到 Lifecycle Manager-设置-系统管理-修补程序设置。
点击“更改下载源”，将下载源类型更改为 UMDS 并配置 UMDS 服务器的下载地址，保存设置。
点击“同步更新”。
获取元数据正常，现在你可以通过 vLCM 使用 UMDS 存储库中的修补程序来管理 vSphere 的生命周期了。
四、UMDS 调度
通过上面的设置，你应该可以正常使用 UMDS 服务器作为 vLCM的下载存储库了，不过使用 UMDS 的这个过程需要手动完成，其实我们可以创建一个自动化任务，让 UMDS 去下载修补程序并 Export 的过程自动完成。我们可以将 Download 和 Export 这两个动作分成两个脚本，以便可以让 Crontab 程序在不同的时间调度不同的任务。
运行 UMDS 下载的脚本 umds-download.sh 和运行 UMDS 导出的脚本 umds-export.sh 如下，将这两个脚本文件放在 UMDS 服务器的 /usr/local/sbin/ 目录并增加执行权限。
root@umds:~# vim umds-download.sh
root@umds:~# cat umds-download.sh
/usr/local/vmware-umds/bin/vmware-umds -D
root@umds:~# vim umds-export.sh
root@umds:~# cat umds-export.sh
/usr/local/vmware-umds/bin/vmware-umds -E
root@umds:~# mv umds-* /usr/local/sbin/
