我在我的服务器上设置了一个节点应用程序,我可以 ssh 进入我的目录并运行
node server.js
伟大的服务器启动并运行良好,但是一旦我关闭我的 ssh 窗口并注销节点服务器停止并且我得到 io.socket 没有定义等等等。
这是我的 server.js
var port = process.env.PORT || 1337;
var io = require('socket.io').listen(port);
var archiveMessages = {};
var channels = ['foo channel', 'bar channel'];
var chat = io.of('/chat');
chat.on('connection', function(socket){
console.log('connected: %s', socket.id);
// push available channel list
socket.emit('available_channel', channels);
socket.on('join', function(value){
console.log('%s joined channel: %s', socket.id, value.channelId);
socket.join(value.channelId);
socket.set('channel_id', value.channelId, function(){
var messages = archiveMessages[value.channelId] || [];
socket.emit('joined', messages);
socket.broadcast.to(value.channelId).emit('user:join', {
id: socket.id
});
});
});
socket.on('post', function(message){
socket.get('channel_id', function(err, channelId){
console.log('%s says<%s channel>: %s', socket.id, channelId, message);
if(!(channelId in archiveMessages)){
archiveMessages[channelId] = [];
}
archiveMessages[channelId].push(message);
socket.emit('posted', {
message: message
});
socket.broadcast.to(channelId).emit('user:message', {
id: socket.id,
message: message
});
});
});
socket.on('disconnect', function(){
console.log('%s disconnected', socket.id);
socket.get('channel_id', function(channelId){
socket.leave(channelId);
socket.broadcast.to(channelId).emit('user:leave', {
id: socket.id
});
});
});
});
var image = io.of('/image');
image.on('connection', function(socket){
socket.on('upload', function(param){
console.log('upload base64 size: %d', param.base64.length);
if(param.download){
socket.emit('download', {
base64: 's' + new Array(65534).join('0') + 'e'
});
}
});
});
我怎样才能让这个 server.js 持续运行。
谢谢
