Solved Kicking all players and Restarting server

Hey I was wondering how would I go about restarting my server on command but kicking all players before restarting with the message

Code:java

("" + ChatColor.DARK_PURPLE + ChatColor.BOLD + "Kevy" + ChatColor.GREEN + ChatColor.BOLD + "&" + ChatColor.GOLD + ChatColor.BOLD + "Azza's" + ChatColor.YELLOW + " Server Restarting Now!")

here's my code so far:

Code:java

                    if (commandLabel.equalsIgnoreCase("restartserver")) {
                        if (!player.isOp()) {
                            player.sendMessage("You don't have permission to do that!");
                        }else{
                            if (player.isOp()) {
                                //kick all players
 
                                //restart server
                            }
                        }
                    }

 

Kicking everyone is easy:

Code:java

for(Player player : Bukkit.getOnlinePlayers()) {
    player.kickPlayer(ChatColor.RED+"Derp'd");
}

Restarting the server is a bit more challenging. It can't actually be done without modifying a launcher bat file or using some crazy reflection. Check out this thread on restarting.

 

TeeePeee Thanks. I was more wondering on how to do the restarting than the kicking but I thought i'd throw it in there to give an explanation on why I was doing it

 

Code:java

    if (commandLabel.equalsIgnoreCase("restartserver")) {
    if (!player.isOp()) {
    // Kick all players
 
    // Restart
    }else{
    player.sendMessage("You don't have permission to do that!");
 
    }
    }
    }

This is good.

 

That is not possible without changing your batch file/whatever you are using.

The best thing you can do is to stop the server with a simple line, i don't remember right now, though.

 

Code:java

    if (commandLabel.equalsIgnoreCase("restartserver")) {
    if (!player.isOp()) {
    for(Player player : Bukkit.getOnlinePlayers()) {
    player.kickPlayer(ChatColor.RED + "Kicked!");
    }
 
    // Restart
    }else{
    player.sendMessage("You don't have permission to do that!");
 
    }
    }
    }

For the restart you need a restart loop in your .bat file

HGPDev and how does one do that

 

Script for your .bat:

Code:

:begin
 
"c:\Program Files\Java\Jre7\bin\java.exe" -Xms1024M -Xmx2048M -jar craftbukkit.jar
 
goto begin

 

HGPDev Thankyou

 

KevyPorter No problem. Just tahg me if you need help

 

HGPDev Wait do I put this in my main .bat

 

KevyPorter You start your server with a .bat file and you need to paste the code i gave you in the .bat file.

 

HGPDev below the stuff I already have?

e.g.

java -Xmx1024M -jar craftbukkit.jar -o true
PAUSE
:begin
"c:\Program Files\Java\Jre7\bin\java.exe" -Xms1024M -Xmx2048M -jar craftbukkit.jar
goto begin

 

KevyPorter No just replace the hole code. So remove your PAUSE and your java -Xmx1024M -jar craftbukkit.jar -o true

 

HGPDev It infinitely loops now

 

KevyPorter True, just get the code form your code in the jar file and the jar file have to run the code and the normal server just runs on the code that you already had. You just have to make a new .bat file and get the .bat file in you .jar file and make it so it runs the .bat file you just created. you leave the old .bat as it is. and you run your server with your old .bat and the code gets the new one.

Not clear? Read: THIS

 

Because you just made an infinite loop. It'd be a lot cleaner to add a shutdown hook for running a timed script to be honest, and have the restart script have a configurable location.

Code:java

String f = /*string of file location*/;
Runtime.getRuntime().addShutdownHook(new Thread() {
    public void run() {
        Runtime.getRuntime().exec(f);
    }
}

From there, your script should have a 5-10 second delay on starting up. You could even use this with the startup script.

You should only hook this if that restart command is used, otherwise you'll end up with an infinite loop again.

 

1Rogue Thanks for helping me explain.. Its a bit hard to explain but you did good!

 

1Rogue Thanks, I'll try that.

HGPDev I figured out another way:
@ ECHO OFF (Without the space)
SET BINDIR=%~dp0
CD /D "%BINDIR%"
:start
"%ProgramFiles%\Java\jre6\bin\java.exe" -Xmx1024M -Xms1024M -jar craftbukkit.jar
goto start

 

The whole point is this will loop whether you are restarting or just stopping in general, don't do that.

 

1Rogue KevyPorter shouldn't be there a pause?

 

There shouldn't be an infinite loop regardless.

 

1Rogue AAah allright.

 

1Rogue But I want my server to be 24/7 so if it crashes it will restart and I will be able to restart it on demand.

Should I just reload instead

 

If your server is crashing then obviously you have other issues to look into, it shouldn't be just randomly crashing...

 

1Rogue Not only if it crashes, It's only crashed once and that was when I was BETA testing a plugin

 

KevyPorter If your testing a plugin, most of the time you look in console what the error is? or something like that.

 

HGPDev I do but if I'm testing my hub plugin and I made a brutal mistake and the server crashes I want it to restart

And I don't understand this (I do understand it but not all of it)

Code:java

String f = /*string of file location*/;
Runtime.getRuntime().addShutdownHook(new Thread() {
    public void run() {
        Runtime.getRuntime().exec(f);
    }
}

 

KevyPorter I Think @1Roguecan explain that better, I have a guess but i dont know for sure

@KevyPorter I Think 1Rogue can explain that better, I have a guess but i dont know for sure

PS: I cant edit my posts, doesn anyone have that too?

wouldn't it be easier to just use remotetoolkit? same thing basically?
