Сначала я создаю сценарий Upstart
. Я использую Amazon EC2 AMI, но есть и другие подобные инструменты для других ОС.
# This is an upstart (http://upstart.ubuntu.com/) script
# to run the node.js server on system boot and make it
# manageable with commands such as
# 'start app' and 'stop app'
#
# This script is to be placed in /etc/init to work with upstart.
#
# Internally the 'initctl' command is used to manage:
# initctl help
# initctl status node-app
# initctl reload node-app
# initctl start node-app
description "node.js forever server for app"
#node child process might not really fork, so don't except it
#expect fork
# used to be: start on startup
# until we found some mounts weren't ready yet while booting:
start on runlevel [2345]
stop on runlevel [016]
# Automatically Respawn:
respawn
respawn limit 99 5
chdir /path/to/directory/node-app
exec node start.js
#post-start script
# # Optionally put a script here that will notifiy you node has (re)started
# # /root/bin/hoptoad.sh "node.js has started!"
#end script
Затем я использовал файл start.js
, в котором «размещено» мое приложение. Мое настоящее приложение находится в index.js
. Вы можете пропустить материал process.on
внизу, но мне он там нравится.
/*jslint node: true */
"use strict";
/**
* File to start using forever, logs crashes, restarts on file changes, etc.
*/
var cmd = ( process.env.DBG ? "node --debug" : "node" );
var forever = require( 'forever' ),
//exec = require('child_process').exec,
child = new( forever.Monitor )( 'index.js', {
'silent': false,
'pidFile': 'pids/node-app.pid',
'watch': true,
'command': cmd,
//"max" : 10,
'watchDirectory': './lib', // Top-level directory to watch from.
'watchIgnoreDotFiles': true, // whether to ignore dot files
'watchIgnorePatterns': [], // array of glob patterns to ignore, merged with contents of watchDirectory + '/.foreverignore' file
'logFile': 'logs/forever.log', // Path to log output from forever process (when daemonized)
//'outFile': 'logs/forever.out', // Path to log output from child stdout
'errFile': 'logs/forever.err'
} );
child.on( "exit", function() {
console.log( 'node-app has exited!' );
} );
child.on( "restart", function() {
console.log( 'node-app has restarted.' );
} );
child.start();
forever.startServer( child );
process.on( 'SIGINT', function() {
console.log( "\nGracefully shutting down \'node forever\' from SIGINT (Ctrl-C)" );
// some other closing procedures go here
process.exit();
} );
process.on( 'exit', function() {
console.log( 'About to exit \'node forever\' process.' );
} );
process.on( 'uncaughtException', function( err ) {
console.log( 'Caught exception in \'node forever\': ' + err );
} );
Работает на меня! Вы можете пропустить выскочку, если просто хотите, чтобы ваше приложение продолжало работать — это мое производственное решение.
