所以,我正在使用Ratchet with
PHP,并且目前已将一个成功的websocket示例上传到我的服务器.
它在我转到SSH之后工作,然后只需手动运行“PHP bin / chat-server.PHP”.
我想知道的是,在商业环境中,如何让聊天服务器保持运行？
谢谢.
做一个守护进程.
如果您使用的是symfony2,则可以使用Process Component.
// in your server start command
$process = new Process('/usr/bin/PHP bin/chat-server.PHP');
$process->start();
sleep(1);
if ($process->isRunning()) {
echo "Server started.\n";
} else {
echo $process->getErrorOutput();
}
// in your server stop command
$process = new Process('ps ax | grep bin/chat-server.PHP');
$process->run();
$output = $process->getOutput();
$lines = preg_split('/\n/',$output);
// kill everything (there can be multiple processes if they are spawned)
$stopped = False;
foreach ($lines as $line) {
$ar = preg_split('/\s+/',trim($line));
if (in_array('/usr/bin/PHP',$ar)
and in_array('bin/chat-server.PHP',$ar)) {
$pid = (int) $ar[0];
posix_kill($pid,SIGKILL);
$stopped = True;
}
}
if ($stopped) {
echo "Server stopped.\n";
} else {
echo "Server not found. Are you sure it's running?\n";
}
如果您使用的是原生PHP,请不要担心,popen是您的朋友！
// in your server start command
_ = popen('/usr/bin/PHP bin/chat-server.PHP','r');
echo "Server started.\n";
// in your server stop command
$output = array();
exec('ps ax | grep bin/chat-server.PHP',&$output);
$lines = preg_split('/\n/',SIGKILL);
$stopped = True;
}
}
if ($stopped) {
echo "Server stopped.\n";
} else {
echo "Server not found. Are you sure it's running?\n";
}
