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.
You can start any application (Node.js, Python, Ruby, binaries in $PATH...) like that:
pm2-go start python app.py
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
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 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
