How to migrate pm2 processes from one server to another?

Question

I am using pm2 for managing node processes on one of the servers. The package is here: https://pm2.keymetrics.io/ It is open source and available both on npmjs and GitHub.

I can easily install it every time using: npm i pm2 -g I love pm2, and not just node processes, I write bash scripts and run them as cron under pm2 and I can easily check the logs.

Some commands:

pm2 --name "process-name" start "bash script.sh"

pm2 --name "node-process" start "node main.js"

pm2 logs node-process

pm2 stop node-process

pm2 restart node-process

There are 2 more commands which are very useful to start pm2 on startup with all the processes automatically.

pm2 startup Will generate startup script.

pm2 save Will update start script with current processes.

Everything is good. But, today I got into a problem.
I am running all pm2 node processes from a folder /mnt/node.
What I want is that I have synced that /mnt/node folder to another server and I am trying to find a way to move all pm2 processes automatically to another server without writing each process once again.

May be someone can help.

Answer 1

You can do this.

On the source server:

pm2 save

copy file saved on ~/.pm2/dump.pm2 to destination server, then:

pm2 resurrect

Haven't try this between two differents server yet but i think it will be ok.
