【问题标题】：Cannot start a service instance in Virtuoso-opensource无法在 Virtuoso-opensource 中启动服务实例
【发布时间】：2017-03-01 13:18:03
【问题描述】：

我正在尝试创建和启动服务实例。但它没有开始。这是我运行的命令：

virtuoso-t +service start +instance MyService

这是我的输出：

The Virtuoso_MyService service is being started

但是localhost:8890无法加载。

详情：

以管理员身份打开 CMD。
3 天前运行相同的命令，服务运行良好，直到我重新启动系统。

随后的命令。

C:\Users\username\Desktop\foldername\MyWork\virtuoso-opensource\bin>virtuoso-t +service create +instance MyService +configfile ..\database\virtuoso.ini

[Using virtuoso.ini in C:\Users\username\Desktop\foldername\MyWork\virtuoso-opensource\database]
The Virtuoso_MyService service has been registered
  and is associated with the executable 

C:\Users\username\Desktop\foldername\MyWork\virtuoso-opensource\bin\virtuoso-t.exe

C:\Users\username\Desktop\foldername\MyWork\virtuoso-opensource\bin>virtuoso-t +service start +instance MyService
The Virtuoso_MyService service is being started

C:\Users\username\Desktop\foldername\MyWork\virtuoso-opensource\bin>virtuoso-t +service list +instance MyService
MyService            Stopped

按照@TallTed 的建议，我已经添加了日志：

16:27:37 Unable to create file virtuoso.lck (File exists).
16:27:37 This probably means you either do not have permission to start
16:27:37 this server, or that virtuoso-t is already running.
16:27:37 If you are absolutely sure that this is not the case, please try
16:27:37 to remove the file virtuoso.lck and start again.

【问题讨论】：

您是否查看过C:\Users\username\Desktop\foldername\MyWork\virtuoso-opensource\database\virtuoso.log 是否有任何错误或其他消息？
@TallTed 我已经添加了日志。我可以看到问题并尝试删除已经存在的 virtuoso.lck 文件。它奏效了。谢谢你。这是一个很大的帮助。

答案在 Virtuoso 日志文件中 --

16:27:37 Unable to create file virtuoso.lck (File exists).
16:27:37 This probably means you either do not have permission to start
16:27:37 this server, or that virtuoso-t is already running.
16:27:37 If you are absolutely sure that this is not the case, please try
16:27:37 to remove the file virtuoso.lck and start again.

按照那里的建议删除 virtuoso.lck 应该可以解决问题。

在正常关机时，Virtuoso 会清理这个文件。如果重新启动电源，或者 Virtuoso 进程以其他方式不干净地终止，则此文件可能会持续存在，就像在这种情况下一样，因此需要手动删除。

Virtuoso website 包含大量信息，包括official Virtuoso manual 和evolving docs, covering Open Source in more detail。

ObDisclaimer：OpenLink Software 产生 Virtuoso，并雇用我。

我刚刚开始学习演奏大师。您能否建议一些提供示例的良好资源。谢谢。

【解决方案2】：

我在 Windows 10 上遇到了同样的问题。我通过访问我的解决了

C:\Program Files\OpenLink Software\Virtuoso OpenSource 7.2\database

并手动删除virtuoso.lck文件

重新启动我的服务器，现在一切正常！
