How to create service which restarts on crash
提问by JProgrammer
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.
我正在使用CreateService. 如果它发生崩溃，该服务将再次正常运行，如果它崩溃，我希望 Windows 重新启动该服务。我知道可以从 services msc 进行设置，请参见下文。
How can I programatically configure the service to always restart if it happens to crash.
如何以编程方式将服务配置为在发生崩溃时始终重新启动。

You want to call ChangeServiceConfig2after you've installed the service. Set the second parameter to SERVICE_CONFIG_FAILURE_ACTIONSand pass in an instance of SERVICE_FAILURE_ACTIONSas the third parameter, something like this:
您想在安装服务后调用ChangeServiceConfig2。将第二个参数设置为SERVICE_CONFIG_FAILURE_ACTIONS并传入SERVICE_FAILURE_ACTIONS的实例作为第三个参数，如下所示：
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);

Used Deltanine's approach, but modified it a bit to be able to control each failure action:
使用了 Deltanine 的方法，但对其进行了一些修改以能够控制每个故障动作：
SERVICE_FAILURE_ACTIONS servFailActions;
SC_ACTION failActions[3];
failActions[0].Type = SC_ACTION_RESTART; //Failure action: Restart Service
failActions[0].Delay = 120000; //number of seconds to wait before performing failure action, in milliseconds = 2minutes
failActions[1].Type = SC_ACTION_RESTART;
failActions[1].Delay = 120000;
failActions[2].Type = SC_ACTION_NONE;
failActions[2].Delay = 120000;
servFailActions.dwResetPeriod = 86400; // Reset Failures Counter, in Seconds = 1day
servFailActions.lpCommand = NULL; //Command to perform due to service failure, not used
servFailActions.lpRebootMsg = NULL; //Message during rebooting computer due to service failure, not used
servFailActions.cActions = 3; // Number of failure action to manage
servFailActions.lpsaActions = failActions;
ChangeServiceConfig2(sc_service, SERVICE_CONFIG_FAILURE_ACTIONS, &servFailActions); //Apply above settings

The answer above will give you the gist... but it wont compile.
上面的答案将为您提供要点......但它不会编译。
try:
尝试：
SERVICE_FAILURE_ACTIONS sfa;
SC_ACTION actions;
sfa.dwResetPeriod = INFINITE;
sfa.lpCommand = NULL;
sfa.lpRebootMsg = NULL;
sfa.cActions = 1;
sfa.lpsaActions = &actions;
sfa.lpsaActions[0].Type = SC_ACTION_RESTART;
sfa.lpsaActions[0].Delay = 5000;
ChangeServiceConfig2(hService, SERVICE_CONFIG_FAILURE_ACTIONS, &sfa)
