isMaster 相当于 pm2 [英] isMaster equivalent for pm2

问题描述

我过去曾使用 cluster 来运行多个实例，但想开始使用 pm2.但是，我有一个只能在启动的实例之一上运行的进程.

I've used cluster in the past for running multiple instances, but would like to start using pm2. However, I have a process that should only run on one of the instances launched.

在使用pm2时，有没有办法确定或识别最初启动的实例，相当于isMaster?

Is there a way to determine or identify the initially launched instance, an equivalent to isMaster when using pm2?

推荐答案

对于那些搜索它的人，我已经找到了这个解决方案.

For those ones who search it, I've found this solution.

if (process.env && process.env.pm_id) {
    //running in pm2 
    if (process.env.pm_id % os.cpus().length !== 0) {
        return;
    }else{
        collectSysInfo();
   }
}
