Quick start

## Installation

The latest PM2 stable version is installable via NPM:

$ sudo npm install git://github.com/cjy37/pm2#master -g

If the above fails use:

$ sudo npm install git://github.com/cjy37/pm2#master -g --unsafe-perm

We recommend Node.JS 0.11.13 for handling the cluster_mode (if you add the -i options to enable scaling and reload).

$ pm2 start app.js --name serverone # Start a process an name it as server one
                                    # you can now stop the process by doing
                                    # pm2 stop serverone

$ pm2 start app.js --node-args="--debug=7001" # --node-args to pass options to node V8

$ pm2 start app.js -i max    # Start maximum processes depending on available CPUs (cluster mode)

$ pm2 start app.js --log-date-format "YYYY-MM-DD HH:mm Z"    # Log will be prefixed with custom time format

$ pm2 start app.json                # Start processes with options declared in app.json
                                    # Go to chapter Multi process JSON declaration for more

$ pm2 start app.js -e err.log -o out.log  # Start and specify error and out log

$ pm2 --run-as-user foo start app.js  # Start app.js as user foo instead of the user that started pm2

$ pm2 --run-as-user foo --run-as-group bar start app.js  # Start app.js as foo:bar instead of the user:group that started pm2

## How to update PM2

Install the latest pm2 version :

$ npm install pm2@latest -g

Then update the in-memory PM2 :

$ pm2 updatePM2

Features

## Transitional state of apps (important)

PM2 is a process manager. PM2 can start, stop, restart and delete processes.

Start a process:

$ pm2 start app.js --name "my-api"
$ pm2 start web.js --name "web-interface"

Now let's say I need to stop the web-interface:

$ pm2 stop web-interface

As you can see the process hasn't disappeared. It's still there but in stopped status.

To restart it just do:

$ pm2 restart web-interface

Now I want to delete the app from the PM2 process list. To do so:

$ pm2 delete web-interface

## Process listing

Monit

To list all running processes:

$ pm2 list
# Or
$ pm2 [list|ls|l|status]

To get more details about a specific process:

$ pm2 describe 0

## Automatic restart process based on memory

Value passed is in megaoctets. Internally it uses the V8 flag --max-old-space-size=MEM to make a process exit when memory exceed a certain amount of RAM used.

CLI:

$ pm2 start big-array.js --max-memory-restart 20

JSON:

{
  "name" : "max_mem",
  "script" : "big-array.js",
  "max_memory_restart" : "20"
}

## Monitoring CPU/Memory usage

Monit

Monitor all processes launched:

$ pm2 monit

## Logs management

Displaying logs in realtime

Monit

Displaying logs of specified process or all processes in realtime:

$ pm2 logs
$ pm2 logs big-api
$ pm2 flush # Clear all the logs

Advanced log interface

Navigate between processes logs in realtime with an ergonomic interface:

$ pm2 ilogs

Reloading all logs (SIGUSR2/Logrotate)

To reload all logs, you can send SIGUSR2 to the PM2 process.

You can also reload all logs via the command line with:

$ pm2 reloadLogs

Options

--merge-logs : merge logs from different instances but keep error and out separated
--log-date-format <format>: prefix logs with formated timestamp (http://momentjs.com/docs/#/parsing/string-format/)

## Clustering (cluster_mode)

The cluster_mode will automatically wrap your Node.js app into the cluster module and will enable you to reload your app without downtime and to scale your processes across all CPUs available.

To enable the cluster_mode, just pass the -i option:

$ pm2 start app.js -i 1

To launch max instances (max depending on the number of CPUs available) and set the load balancer to balance queries among process:

$ pm2 start app.js --name "API" -i max

If your app is well-designed (stateless) you'll be able to process many more queries.

Important concepts to make a Node.js app stateless:

Sessions must not be stored in memory but shared via a database (Redis, Mongo, whatever)
WebSocket/Socket.io should communicate via a database

## Reloading without downtime

As opposed to restart, which kills and restarts the process, reload achieves a 0-second-downtime reload.

Warning This feature only works for apps in cluster_mode, that uses HTTP/HTTPS/Socket connections.

To reload an app:

$ pm2 reload api

If the reload system hasn't managed to reload your app, a timeout will simply kill the process and will restart it.

Graceful reload

Sometimes you can experience a very long reload, or a reload that doesn't work (fallback to restart).

It means that your app still has open connections on exit.

To work around this problem you have to use the graceful reload. Graceful reload is a mechanism that will send a shutdown message to your process before reloading it. You can control the time that the app has to shutdown via the PM2_GRACEFUL_TIMEOUT environment variable.

Example:

process.on('message', function(msg) {
  if (msg == 'shutdown') {
    // Your process is going to be reloaded
    // You have to close all database/socket.io/* connections

    console.log('Closing all connections...');

    // You will have 4000ms to close all connections before
    // the reload mechanism will try to do its job

    setTimeout(function() {
      console.log('Finished closing connections');
      // This timeout means that all connections have been closed
      // Now we can exit to let the reload mechanism do its job
      process.exit(0);
    }, 1500);
  }
});

Then use the command:

$ pm2 gracefulReload [all|name]

When PM2 starts a new process to replace an old one, it will wait for the new process to begin listening to a connection before sending the shutdown message to the old one. If a script does not need to listen to a connection, it can manually tell PM2 that the process has started up by calling process.send('online').

## Startup script

PM2 has the amazing ability to generate startup scripts and configure them. PM2 is also smart enough to save all your process list and to bring back all your processes on restart.

$ pm2 startup [ubuntu|centos|gentoo|systemd]

Once you have started the apps and want to keep them on server reboot do:

$ pm2 save

Warning It's tricky to make this feature work generically, so once PM2 has setup your startup script, reboot your server to make sure that PM2 has launched your apps!

More information

Three types of startup scripts are available:

SystemV init script (with the option ubuntu or centos)
OpenRC init script (with the option gentoo)
SystemD init script (with the systemd option)

The startup options are using:

ubuntu will use updaterc.d and the script lib/scripts/pm2-init.sh
centos will use chkconfig and the script lib/scripts/pm2-init-centos.sh
gentoo will use rc-update and the script lib/scripts/pm2
systemd will use systemctl and the script lib/scripts/pm2.service

User permissions

Let's say you want the startup script to be executed under another user.

Just use the -u <username> option !

$ pm2 startup ubuntu -u www

Related commands

Dump all processes status and environment managed by PM2:

$ pm2 dump

It populates the file ~/.pm2/dump.pm2 by default.

To bring back the latest dump:

$ pm2 [resurrect|save]

## Watch & Restart

PM2 can automatically restart your app when a file changes in the current directory or its subdirectories:

$ pm2 start app.js --watch

If --watch is enabled, stopping it won't stop watching:

pm2 stop 0 'll not stop watching
pm2 stop --watch 0 'll stop watching

Restart toggle the watch parameter when triggered.

To watch specifics paths, please use a JSON app declaration, watch can take a string or an array of paths. Default is true:

{
  "watch": ["server", "client"],
  "ignoreWatch" : ["node_modules", "client/img"]
}

## JSON app declaration

You can define parameters for your apps in processes.json:

{
  "apps" : [{
    "name"        : "echo",
    "script"      : "examples/args.js",
    "args"        : "['--toto=heya coco', '-d', '1']",
    "log_date_format"  : "YYYY-MM-DD HH:mm Z",
    "ignoreWatch" : ["[\\/\\\\]\\./", "node_modules"],
    "watch"       : "true",
    "node_args"   : "--harmony",
    "cwd"         : "/this/is/a/path/to/start/script",
    "env": {
        "NODE_ENV": "production",
        "AWESOME_SERVICE_API_TOKEN": "xxx"
    }
  },{
    "name"       : "api",
    "script"     : "./examples/child.js",
    "instances"  : "4",
    "log_date_format"  : "YYYY-MM-DD",
    "error_file" : "./examples/child-err.log",
    "out_file"   : "./examples/child-out.log",
    "pid_file"   : "./examples/child.pid",
    "exec_mode"  : "cluster_mode",
    "port"       : 9005
  },{
    "name"       : "auto-kill",
    "script"     : "./examples/killfast.js",
    "min_uptime" : "100",
    "exec_mode"  : "fork_mode"
  }]
}

Then run:

$ pm2 start processes.json
$ pm2 stop processes.json
$ pm2 delete processes.json
$ pm2 restart processes.json

A few notes about JSON app declarations:

All command line options passed when using the JSON app declaration will be dropped i.e.

$ cat node-app-1.json

{
  "name" : "node-app-1",
  "script" : "app.js",
  "cwd" : "/srv/node-app-1/current"
}

$ pm2 --run-as-user app start node-app-1.json

$ ps aux | grep node-app
root 14735 5.8 1.1 752476 83932 ? Sl 00:08 0:00 pm2: node-app-1  <-- owned by the default user (root), not app

JSON app declarations are additive. Continuing from above:

$ pm2 start node-app-2.json
$ ps aux | grep node-app
root  14735  5.8  1.1  752476  83932 ? Sl 00:08 0:00 pm2: node-app-1
root  24271  0.0  0.3  696428  24208 ? Sl 17:36 0:00 pm2: node-app-2

Note that if you execute pm2 start node-app-2 again, it will spawn an additional instance node-app-2.

cwd: your JSON declaration does not need to reside with your script. If you wish to maintain the JSON(s) in a location other than your script (say, /etc/pm2/conf.d/node-app.json) you will need to use the cwd feature. (Note, this is especially helpful for capistrano style directory structures that use symlinks.) Files can be either relative to the cwd directory, or absolute (example below.)
The following are valid options for JSON app declarations:

[{
  "name"             : "node-app",
  "cwd"              : "/srv/node-app/current",
  "args"             : "['--toto=heya coco', '-d', '1']",
  "script"           : "bin/app.js",
  "node_args"        : "--harmony",
  "log_date_format"  : "YYYY-MM-DD HH:mm Z",
  "error_file"       : "/var/log/node-app/node-app.stderr.log",
  "out_file"         : "log/node-app.stdout.log",
  "pid_file"         : "pids/node-geo-api.pid",
  "run_as_user"      : "app",
  "run_as_group"     : "www-data",
  "instances"        : "6", //or 'max'
  "min_uptime"       : "200", // milliseconds, defaults to 1000
  "max_restarts"     : "10", // defaults to 15
  "cron_restart"     : "1 0 * * *",
  "watch"            : "false",
  "ignoreWatch"      : ["[\\/\\\\]\\./", "node_modules"],
  "merge_logs"       : "true",
  "exec_interpreter" : "node",
  "exec_mode"        : "fork_mode",
  "env": {
    "NODE_ENV": "production",
    "AWESOME_SERVICE_API_TOKEN": "xxx"
  }
}]

# Deployment (PM2 >= 0.9.0)

PM2 embed a simple and powerful deployment system with revision tracing. It's based on https://github.com/visionmedia/deploy

A step-by-step tutorial is available here : Deploy and Iterate faster with PM2 deploy

Getting started with deployment

Please read the Considerations to use PM2 deploy

1- Generate a sample ecosystem.json file that list processes and deployment environment

$ pm2 ecosystem

In the current folder a ecosystem.json file will be created. It contains this:

{
  "apps" : [{
    "name"      : "API",
    "script"    : "app.js",
    "env": {
      "COMMON_VARIABLE": "true"
    },
    "env_production" : {
      "NODE_ENV": "production"
    }
  },{
    "name"      : "WEB",
    "script"    : "web.js"
  }],
  "deploy" : {
    "production" : {
      "user" : "node",
      "host" : "212.83.163.1",
      "ref"  : "origin/master",
      "repo" : "[email protected]:repo.git",
      "path" : "/var/www/production",
      "post-deploy" : "pm2 startOrRestart ecosystem.json --env production"
    },
    "dev" : {
      "user" : "node",
      "host" : "212.83.163.1",
      "ref"  : "origin/master",
      "repo" : "[email protected]:repo.git",
      "path" : "/var/www/development",
      "post-deploy" : "pm2 startOrRestart ecosystem.json --env dev"
    }
  }
}

Edit the file according to your needs.

2- Be sure that you have the public ssh key on your local machine

$ ssh-keygen -t rsa
$ ssh-copy-id [email protected]

3- Now initialize the remote folder with:

$ pm2 deploy <configuration_file> <environment> setup

E.g:

$ pm2 deploy ecosystem.json production setup

This command will create all the folders on your remote server.

4- Deploy your code

$ pm2 deploy ecosystem.json production

Now your code will be populated, installed and started with PM2

## Deployment options

Display deploy help via pm2 deploy help:

$ pm2 deploy <configuration_file> <environment> <command>

  Commands:
    setup                run remote setup commands
    update               update deploy to the latest release
    revert [n]           revert to [n]th last deployment or 1
    curr[ent]            output current release commit
    prev[ious]           output previous release commit
    exec|run <cmd>       execute the given <cmd>
    list                 list previous deploy commits
    [ref]                deploy to [ref], the "ref" setting, or latest tag

Commands

$ pm2 startOrRestart all.json            # Invoke restart on all apps in JSON
$ pm2 startOrReload all.json             # Invoke reload
$ pm2 startOrGracefulReload all.json     # Invoke gracefulReload

## Considerations

You might want to commit your node_modules folder (#622) or add the npm install command to the post-deploy section: "post-deploy" : "npm install && pm2 startOrRestart ecosystem.json --env production"
Verify that your remote server has the permission to git clone the repository
You can declare specific environment variable depending on the environment you want to deploy the code to. For instance to declare variables for the production environment, just add "env_production": {} and declare that variables.
PM2 will look by default to ecosystem.json. So you can skip the <configuration_file> options if it's the case
You can embed the "apps" & "deploy" section in the package.json
It deploys your code via ssh, you don't need any dependencies
Process are initialized / started automatically depending on application name in ecosystem.json
PM2-deploy repository is there: pm2-deploy

## Contributing

The module is https://github.com/Unitech/pm2-deploy Feel free to PR for any changes or fix.

# Using PM2 programmatically

PM2 can be used programmatically, meaning that you can embed a process manager directly in your code, spawn processes, keep them alive even if the main script is exited.

Check out this article for more informations.

Simple example

This will require pm2, launch test.js, list processes then exit the script. You will notice that after exiting this script you will be able to see test.js process with pm2 list

$ npm install pm2 --save

var pm2 = require('pm2');

// Connect or launch PM2
pm2.connect(function(err) {

  // Start a script on the current folder
  pm2.start('test.js', { name: 'test' }, function(err, proc) {
    if (err) throw new Error('err');

    // Get all processes running
    pm2.list(function(err, process_list) {
      console.log(process_list);

      // Disconnect to PM2
      pm2.disconnect(function() { process.exit(0) });
    });
  });
})

## Programmatic API

Method name	API
Connect/Launch	pm2.connect(fn(err){})
Disconnect	pm2.disconnect(fn(err, proc){})

Consideration with .connect: the .connect method connect to the local PM2, but if PM2 is not up, it will launch it and will put in in background as you launched it via CLI.

Sending a system signal to a process:

$ pm2 sendSignal SIGUSR2 my-app

## Configuration file

You can specify the following options by editing the file ~/.pm2/custom_options.sh:

PM2_RPC_PORT
PM2_PUB_PORT
PM2_BIND_ADDR
PM2_API_PORT
PM2_GRACEFUL_TIMEOUT
PM2_MODIFY_REQUIRE

API health endpoint

$ pm2 web

## Enabling Harmony ES6

The --node-args option permit to launch script with V8 flags, so to enable harmony for a process just do this:

$ pm2 start my_app.js --node-args="--harmony"

And with JSON declaration:

[{
  "name" : "ES6",
  "script" : "es6.js",
  "node_args" : "--harmony"
}]

## CoffeeScript

$ pm2 start my_app.coffee

That's all!

Knowledge

## Stateless apps

We recommend (and you must) write stateless NodeJS apps. Apps that don't retain any form of local variables or local instances or whatever local. Every data, states, websocket session, session data, must be shared via any kind of database.

We recommend using Redis for sharing session data, websocket.

## Setup pm2 on a server

How To Use pm2 to Setup a Node.js Production Environment On An Ubuntu VPS

## Log and PID files

By default, logs (error and output), pid files, dumps, and PM2 logs are located in ~/.pm2/:

.pm2/
├── dump.pm2
├── custom_options.sh
├── pm2.log
├── pm2.pid
├── logs
└── pids

## Execute any kind of script

In fork mode almost all options are the same as the cluster mode. But there is no reload or gracefulReload command.

You can also exec scripts written in other languages:

$ pm2 start my-bash-script.sh -x --interpreter bash

$ pm2 start my-python-script.py -x --interpreter python

The interpreter is deduced from the file extension from the following list.

## Is my production server ready for PM2?

Just try the tests before using PM2 on your production server

$ git clone https://github.com/Unitech/pm2.git
$ cd pm2
$ npm install  # Or do NODE_ENV=development npm install if some packages are missing
$ npm test

If a test is broken please report us issues here Also make sure you have all dependencies needed. For Ubuntu:

$ sudo apt-get install build-essential
# nvm is a Node.js version manager - https://github.com/creationix/nvm
$ wget -qO- https://raw.github.com/creationix/nvm/master/install.sh | sh
$ nvm install v0.11.10
$ nvm use v0.11.10
$ nvm alias default v0.11.10

## Contributing/Development mode

To hack PM2, it's very simple:

$ pm2 kill   # kill the current pm2
$ git clone my_pm2_fork.git
$ cd pm2/
$ DEBUG=* PM2_DEBUG=true ./bin/pm2 --no-daemon

Each time you edit the code, be sure to kill and restart PM2 to make changes taking effect.

Install PM2 development

$ npm install git://github.com/Unitech/pm2#development -g

## Known bugs and workarounds

First, install the lastest PM2 version:

$ npm install -g pm2@latest
