如何在不清除Jenkins安装的情况下手动重启Jenkins（Windows服务器）

Hey there! Let me walk you through a few straightforward, safe ways to restart Jenkins on your Windows server—no need to wipe your existing installation or lose any configurations.

Method 1: Use Jenkins' Built-in Restart Endpoint #

This is the easiest way if you can access the Jenkins web UI:

• Open your Jenkins dashboard (usually at http://<your-server-ip>:8080 or http://localhost:8080) and log in.
• Append /restart to the end of the URL in your address bar. For example:

  http://localhost:8080/restart
  

• You’ll see a confirmation page—click Yes to trigger an immediate restart.
• Pro tip: If you want to wait for all running builds to finish before restarting, use /safeRestart instead:

  http://localhost:8080/safeRestart
  

Method 2: Restart via Windows Services #

Since Jenkins typically runs as a Windows service, this method works even if the web UI is unresponsive:

• Press Win + R to open the Run dialog, type services.msc, and hit Enter.
• Scroll through the list to find the service named Jenkins (if you’ve customized the service name, look for something containing "Jenkins").
• Right-click the service and select Restart from the menu. Wait a few moments for the service to stop and start back up.

Method 3: Use Command Line (CMD/PowerShell) #

If you prefer using the terminal, these commands will get the job done:

Using Command Prompt (CMD) #

1. Open CMD as Administrator.
2. Stop the Jenkins service first:

   net stop Jenkins
   

3. Once it’s stopped, start it back up:

   net start Jenkins
   

Using PowerShell #

1. Open PowerShell as Administrator.
2. You can restart the service in one line:

   Restart-Service Jenkins
   

3. If you’re unsure of the exact service name, run this to find it:

   Get-Service | Where-Object {$_.DisplayName -like "*Jenkins*"}
   

   Use the Name value from the output in place of "Jenkins" in the restart command.

Quick Notes #

• Always check if there are active builds running before restarting. The /safeRestart option or waiting for builds to finish helps avoid broken builds or data loss.
• If Jenkins is frozen and the web UI isn’t loading, the Windows Services or command line methods are your best bet—they’ll force the service to restart regardless of the UI state.
