仅当注册表值不存在时才执行 [英] Exec onlyif registry value is not present

问题描述

**EDIT**

我通过玩弄找到了一个解决方案:

I found a solution by playing around:

class add_route
{
        exec { "route_to_internal_network":
                command => "C:\Windows\System32\ROUTE.EXE add 192.168.5.254 mask 255.255.255.255 10.5.5.5 -p",
                unless => "C:\Windows\System32\reg.exe query HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\PersistentRoutes /f 192.168.5.254,255.255.252.0,10.5.5.5,1",
        }
}

**EDIT**

我正在尝试编写一个 puppet 清单，以向我的某些 Windows 主机服务器添加持久静态路由.到目前为止，我正在考虑创建一个这样的类:

I am trying to write a puppet manifest to add a persistent static route to some of my Windows host servers. So far, I am thinking of creating a class that does:

class add_route
{
    exec { "route_to_internal_network":
        command => "C:\Windows\System32\ROUTE.EXE add 192.168.5.254 mask 255.255.255.255 10.5.5.5 -p",
    }
}

但是，每次木偶客户端与木偶主人签到时，此清单都会执行该命令.

However, this manifest will exec the command every time the puppet client checks in with the puppet master.

我希望在我的班级中使用 onlyif，但是在尝试检查包含我的路由的缺失注册表值时似乎有点混乱.这是最好的方法吗?还有其他想法吗?

I was hoping to use onlyif in my class, but it seems a little confusing when trying to check for an absent registry value that contains my route. Is this the best way to do this? Any other ideas?

我想我需要做一些类似的事情:

I imagine I need to do something like:

class add_route
{
    exec { "route_to_internal_network":
        command => "C:\Windows\System32\ROUTE.EXE add 192.168.5.254 mask 255.255.255.255 10.5.5.5 -p",
        onlyif => ???
    }
}

我希望我的 onlyif 语句能够匹配

I was hoping my onlyif statement would match to

C:\Windows\System32\reg.exe query HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\PersistentRoutes /f '192.168.5.254,255.255.255.255,10.5.5.5,1'

如果上面命令的结果是:

If the result of the above command is:

搜索结束:找到 0 个匹配项.

End of search: 0 match(es) found.

但是，我认为 onlyif 只是在寻找返回码，因此无论是否找到此值，该命令都会成功完成.

However, I think the onlyif is just looking for a return code, so whether or not this value is found, the command completes successfully.

有谁知道我如何检查人偶清单中是否缺少注册表值?

Does anyone know how I could check for the absence of a registry value in a puppet manifest?
