背景介绍：
实现如上图所示的，页面一键控制服务器IISRESET
服务器上部署了EnvAgency这个Service来接受请求并处理以及返回，但是IISRESET这个请求特殊，因为IISRESET后会重启程序池，包括EnvAgency程序，就不能返回IISRESET请求的具体结果，但是IISRESET的单次成功率不高，又后果失败影响大，所以必须保证IISRESET的成功。试过很多中方法，具体尝试方法记录于http://4453154.blog.51cto.com/4443154/1689318，某些情况下，这些方法是可行的。但是我这边由于严格的域帐号机器帐号控制导致不可行。所以换了如下方法：
环境系统调用服务器上代理，代理触发服务器上IISRESET的应用，该应用会启动iisreset并且读取返回，如果返回是正确的，就退出，否则继续调用iisreset，这样就确保多次后iis启动成功。由于IISRESET应用是写成Console程序，不受IIS程序池影响。并且加入Nlog来记录相应信息，方便出问题后排查。
在判断iis启动成功方面：采用循环5秒请求下服务器时间，看服务器是否有反应来判断启动是否成功。
应用存放目录：
D:\\websites\\EnvCmd\\cmdtest
IISRESET的应用配置具体代码如下：
using NLog;
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace cmdtest
{
public class ProcessUtil
{
private static readonly Logger Logger = LogManager.GetCurrentClassLogger();
public static bool IISReset()
{
Logger.Info("Start IISRESET");
int flag = 0;
string output = IISResetProcess();
Logger.Info(output);
string regx = "正在尝试停止...\r\r\nInternet 服务已成功停止\r\r\n正在尝试启动...\r\r\nInternet 服务已成功启动";
while (flag < 10 && !output.Contains(regx))
{
output = IISResetProcess();
Logger.Info(output);
flag++;
}
bool result = output.Contains(regx);
Logger.Info("Finish IISRESET - result : " + result);
return result;
}
public static string IISResetProcess()
{
Process pro = new Process();
// 设置命令行、参数
pro.StartInfo.FileName = "cmd.exe";
pro.StartInfo.UseShellExecute = false;
pro.StartInfo.RedirectStandardInput = true;
pro.StartInfo.RedirectStandardOutput = true;
pro.StartInfo.RedirectStandardError = true;
pro.StartInfo.CreateNoWindow = true;
// 启动CMD
pro.Start();
// 运行端口检查命令
pro.StandardInput.WriteLine("iisreset");
pro.StandardInput.WriteLine("exit");
return pro.StandardOutput.ReadToEnd();
}
}
}using NLog;
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace cmdtest
{
class Program
{
private static readonly Logger Logger = LogManager.GetCurrentClassLogger();
static void Main(string[] args)
{
Logger.Info("test");
Console.WriteLine(ProcessUtil.IISReset());
}
}
}服务器代理EvnAgency中IISReset调用如下：
public JsonResult IISReset(PostPackBase pack)
{
var resp = new APIResponse<string>()
{
StateCode = StateCode.Success,
Message = ""
};
var accessToken = LoginSecurity.DecodeAccessToken(pack.Token);
if (accessToken == null)
{
resp.StateCode = StateCode.Fail;
resp.Message = "操作用户无法识别！";
}
else if (accessToken.ExpiredTime < DateTime.Now)
{
resp.StateCode = StateCode.Fail;
resp.Message = "登陆信息过期！";
}
else
{
try
{
var token = LoginSecurity.DecodeAccessToken(pack.Token);
EnvMachine envmachine = EnvMachineBiz.GetCurrentMachine();
string ip = envmachine.IP;
Logger.Info("IISReset start by " + token.Alias + " on " + ip);
string str = string.Format("{0} Reset IIS on {1} ", token.Alias, ip) ;
EnvOperationLogBiz.LogOptIISReset(envmachine.EnvSubId, token.Alias, str, envmachine.Id);
IISUtil.IISReset();
}
catch (Exception ex)
{
resp.StateCode = StateCode.Fail;
resp.Message += ex.ToString();
Logger.ErrorException("IISReset status result : Exception, " + ex.ToString(), ex);
}
}
return Json(resp, JsonRequestBehavior.DenyGet);
}具体调用应用程序代码如下：
public static void IISReset()
{
Logger.Info("Start D:\\websites\\EnvCmd\\cmdtest");
Process.Start("D:\\websites\\EnvCmd\\cmdtest");
}环境管理系统中前端代码如下：
html代码如下
<li><a onclick="javascript: pageui.render('iisreset')">IIS Reset</a></li>js代码如下
////// 主页面 //////
