我有一些带有少量RAM的DigitalOcean液滴，但我应该在那里托管很多pm2进程(更准确地说，集群模式下为9-8(提供-i 0(，分叉模式下为1(。这些进程是NodeJS Express服务器，为React.js项目进行服务器端渲染。
因此，正如预期的那样，有时pm2会因为没有足够的RAM而崩溃，而且在崩溃后，它显然不会恢复所有进程，尽管启用了启动守护进程。
我知道，启动守护程序只在系统启动时工作，所以现在每次pm2崩溃时，我都应该手动转到液滴并在其上重新启动系统。
有什么解决办法可以使这个过程自动化吗？或者，可能存在一些在pm2启动时工作的pm2守护进程？
感谢您的帮助
提前感谢！

将PM2连接到PM2+，因此将PM2链接到PM2+的代理将充当第二个看门狗。如果主PM2崩溃，PM2+代理将使用以前的进程列表重新生成PM2
