在Windows Server 2016上使用Asp.Net Core 3.0 API应用需要频繁重启的问题,可能是由于IIS进程池空闲超时设置导致的。可以通过更改IIS进程池的空闲超时设置来解决这个问题。
以下是一个示例代码,用于更改IIS进程池的空闲超时设置:
using (ServerManager serverManager = new ServerManager())
{
Configuration configuration = serverManager.GetApplicationHostConfiguration();
ConfigurationSection applicationPoolsSection = configuration.GetSection("system.applicationHost/applicationPools");
ConfigurationElementCollection applicationPoolsCollection = applicationPoolsSection.GetCollection();
ConfigurationElement applicationPoolElement = FindElement(applicationPoolsCollection, "add", "name", "YourApplicationPoolName");
if (applicationPoolElement == null)
throw new InvalidOperationException("Application pool not found");
ConfigurationElement recyclingElement = applicationPoolElement.GetChildElement("recycling");
ConfigurationElement periodicRestartElement = recyclingElement.GetChildElement("periodicRestart");
periodicRestartElement["time"] = TimeSpan.Zero; // 设置空闲超时为0,禁用空闲超时
serverManager.CommitChanges();
}
private static ConfigurationElement FindElement(ConfigurationElementCollection collection, string elementTagName, params string[] keyValues)
{
foreach (ConfigurationElement element in collection)
{
if (String.Equals(element.ElementTagName, elementTagName, StringComparison.OrdinalIgnoreCase))
{
bool matches = true;
for (int i = 0; i < keyValues.Length; i += 2)
{
object o = element.GetAttributeValue(keyValues[i]);
string value = null;
if (o != null)
{
value = o.ToString();
}
if (!String.Equals(value, keyValues[i + 1], StringComparison.OrdinalIgnoreCase))
{
matches = false;
break;
}
}
if (matches)
{
return element;
}
}
}
return null;
}
请将代码中的"YourApplicationPoolName"替换为您实际的应用程序池名称。这段代码将设置应用程序池的空闲超时为0,禁用空闲超时,从而避免应用程序频繁重启的问题。
注意:在使用此代码之前,请确保安装了Microsoft.Web.Administration包,可以通过NuGet包管理器安装。
