在PM2中传递和读取参数

Question

I want to pass command line arguments to my script. In forever I used to pass arguments like

forever start example.js 8080

I am unable to figure out how to do it in PM2. I tried

pm2 start KratosReq.js  -- -p 8080

but while reading from process.argv, the array contains

[ 'node', '/usr/local/lib/node_modules/pm2/lib/ProcessContainerFork.js' ]

Answer 1

Pm2 wrap your init script and fork node processes(cluster mode) , i think that is why you have that output , looking for declare enviroment variables in pm2 , you can use a json file to start up your server , or you can just start passing --node-args argument(checking pm2 help , there is that argument) , something like :

pm2 start KratosReq.js  --node-args="-p=8080"

Hope this could help.
