PM2-GO

PM2-GO is a clone of Unitech/pm2 made using golang. The aim is to make it easy to install. Performance is the bonus.

Starting an application in production mode is as easy as:

pm2-go start python app.py

Works on Linux & macOS, no support for Windows.

Start an application

You can start any application (Node.js, Python, Ruby, binaries in $PATH...) like that:

pm2-go start python app.py

Managing Applications

Once applications are started you can manage them easily:

To list all running applications:

pm2-go ls

Managing apps is straightforward:

pm2-go stop     <app_name|id|json_conf|'all'>
pm2-go restart  <app_name|id|json_conf|'all'>
pm2-go delete   <app_name|id|json_conf|'all'>
pm2-go flush    <app_name|id|json_conf|'all'>

To see real-time logs:

pm2-go logs <app_name|id>

To dump all processes

pm2-go dump

To restore all processes

pm2-go restore

Extend Logs

Logs can be extended by using scripts placed in $HOME/.pm2-go/scripts.

To leverage the use of scripts, specify the scripts inside .json file containing processes

e.g.

[
    {
        "name": "python-test",
        "args": ["-u", "test.py"],
        "autorestart": true,
        "cwd": "./examples",
        "scripts": ["logs_date"],
        "executable_path": "python3",
        "cron_restart": "* * * * *"
    }
]

Example script: logs_date.sh

It adds corresponding date & time to each line from the process output

Log Rotation

Log rotation can be enabled by setting logrotate to true using

pm2-go config set logrotate true

Logs will be rotated every x size (default: 10MB) and y number of files (default: 10). It can be configured using

pm2-go config set logrotate_size 10M (e.g. 10M, 10K, 10G)
pm2-go config set logrotate_max_files 10
