如何创建崩溃时重新启动的服务 [英] How to create service which restarts on crash

问题描述

我使用。将第二个参数设置为 SERVICE_CONFIG_FAILURE_ACTIONS ，并传递 SERVICE_FAILURE_ACTIONS 作为第三个参数，类似这样：

  int numBytes = sizeof（SERVICE_FAILURE_ACTIONS）+ sizeof（SC_ACTION）; 
 std :: vector< char> buffer（numBytes）; 
 
 SERVICE_FAILURE_ACTIONS * sfa = reinterpret_cast< SERVICE_FAILURE_ACTIONS *>（& buffer [0]）; 
 sfa.dwResetPeriod = INFINITE; 
 sfa.cActions = 1; 
 sfa.lpsaActions [0] .Type = SC_ACTION_RESTART; 
 sfa.lpsaActions [0] .Delay = 5000; //等待5秒后重新启动
 
 ChangeServiceConfig2（hService，SERVICE_CONFIG_FAILURE_ACTIONS，sfa）; 
  

I am creating a service using CreateService. The service will run again fine if it happens to crash and I would like to have Windows restart the service if it crashes. I know it is possible to set this up from the services msc see below.

How can I programatically configure the service to always restart if it happens to crash.

解决方案

You want to call ChangeServiceConfig2 after you've installed the service. Set the second parameter to SERVICE_CONFIG_FAILURE_ACTIONS and pass in an instance of SERVICE_FAILURE_ACTIONS as the third parameter, something like this:

int numBytes = sizeof(SERVICE_FAILURE_ACTIONS) + sizeof(SC_ACTION);
std::vector<char> buffer(numBytes);

SERVICE_FAILURE_ACTIONS *sfa = reinterpret_cast<SERVICE_FAILURE_ACTIONS *>(&buffer[0]);
sfa.dwResetPeriod = INFINITE;
sfa.cActions = 1;
sfa.lpsaActions[0].Type = SC_ACTION_RESTART;
sfa.lpsaActions[0].Delay = 5000; // wait 5 seconds before restarting

ChangeServiceConfig2(hService, SERVICE_CONFIG_FAILURE_ACTIONS, sfa);
