I'm using
router.post('/create', function(req, res) {
pool.query("SELECT MAX(server_port) FROM servers", function(err, rows) {
if (err) return console.log(err);
var serverPort = parseInt(rows[0]['MAX(server_port)']) + 1;
var decoder = new StringDecoder('utf8')
var child = spawn('/home/steam/steamcmd/csgo/srcds_run',
['-game csgo' ,'-console' ,'+game_type 0' ,'+game_mode ' + req.body.serverType, '+map ' + req.body.serverMap,
'-tickrate ' + req.body.tickRate, '+maxplayers ' + req.body.maxPlayers,
'+hostname ' + req.body.serverName, '+port ' + serverPort, '+password '],
{
detached: true
});
child.stderr.on('data', function(err) {
console.log(err);
});
child.stdout.on('data', function(chunk) {
});
console.log(child.pid);
var inserts = {
server_name: req.body.serverName || 'CSGO Quick Server',
server_players: req.body.maxPlayers,
server_owned_by: req.session.username,
serverPID: child.pid,
server_port: serverPort,
server_tickrate: req.body.tickRate,
server_map: req.body.serverMap,
server_type: req.body.serverType
};
pool.query("INSERT INTO `servers` SET ?", inserts, function(err, insert) {
if (err) return console.log(err);
res.json({'success': true});
});
});
});
to create a spawn for CS:GO (video game) to run a server from the front-end, and that is working great, the server goes up and runs. But I have to run the program ./srcds_run which sets some variables and then runs ./srcds_linux so I keep track of the PID of ./srcds_run but when I go to kill it, the ./srcds_linux still runs and I'm not sure how to get the PID of it.
Trying to killall won't work because there might be another ./srcds_linux running that I do not want to kill.
Basically what I am asking is, how do I kill the process that was created by ./srcds_run.
This is how I'm destroying it:
router.get('/destroy', function(req, res) {
if (req.session.hasOwnProperty('username')) {
pool.query("SELECT * FROM servers WHERE server_owned_by = ?", [req.session.username], function(err, rows) {
if (err) return res.redirect('/');
if (rows.length >= 1) {
console.log('here');
exec('kill ' + rows[0].serverPID, function(err, stdout, stderr) {
if (err) return console.log(err);
if (stderr) return console.log(stderr);
console.log(stdout);
pool.query("DELETE FROM servers WHERE serverPID = ?", [rows[0].serverPID], function(err) {
if (err) console.log(err);
res.redirect('/servers');
});
});
}
});
} else {
res.redirect('/');
}
});
And this is what I end up with
root@PanicWoW:~# ps aux | grep csgo
root 16995 0.0 0.0 4440 704 ? Ss 06:45 0:00 /bin/sh /home/steam/steamcmd/csgo/srcds_run -game csgo -console +game_type 0 +game_mode 0 +map de_dust2 -tickrate 64 +maxplayers 10 +hostname +port 27016 +password
root 17022 6.3 6.4 262072 132960 ? Sl 06:45 0:05 ./srcds_linux -game csgo -console +game_type 0 +game_mode 0 +map de_dust2 -tickrate 64 +maxplayers 10 +hostname +port 27016 +password
So when I kill 16995, the other process continues to run instead of dying with it, even though 16995 created it.
Sorry if this is confusing I'm not sure how to word this as it is fairly new area for me (not the JS, but dealing with child_processes and linux) thanks a lot. If I can clarify anything please ask.
