具體代碼如下所示：
?php
class Worker{
public static $count = 2;
public static function runAll(){
static::runMaster();
static::moniProcess();
}
//開啟主進程
public static function runMaster(){
//確保進程有最大操作權限
unmask(0);
$pid = pcntl_fork();
if($pid > 0){
echo "主進程進程 $pid \n";
exit;
}else if($pid == 0){
if(-1 === posix_setsid()){
throw new Exception("setsid fail");
}
for ($i=0; $i self::$count; $i++) {
static::runWorker();
}
@cli_set_process_title("master_process");
}else{
throw new Exception("創(chuàng)建主進程失敗");
}
}
//開啟子進程
public static function runWorker(){
unmask(0);
$pid = pcntl_fork();
if($pid > 0){
// echo "創(chuàng)建子進程 $pid \n";
}else if($pid == 0){
if(-1 === posix_setsid()){
throw new Exception("setsid fail");
}
@cli_set_process_title("worker_process");
while(1){
sleep(1);
}
}else{
throw new Exception("創(chuàng)建子進程失敗");
}
}
//監(jiān)控worker進程
public function moniProcess(){
while( $pid = pcntl_wait($status)){
if($pid == -1){
break;
}else{
static::runWorker();
}
}
}
}
Worker::runAll();

執(zhí)行命令 kill 65，殺死進程 65 則master_process 進程會再自動開啟一個子進程
