如何在 Upstart 中正确启动节点服务器,以便 APN 正常工作



当我通过node server.js从命令行运行服务器时,它的运行方式与使用暴发户脚本启动服务器时不同(特别是推送通知工作)。我应该如何修改我的暴发户脚本来解决这个问题?

这是一个示例服务器,其中推送在新贵中失败,在命令行中成功

var apn = require('apn');
var options = {
  passphrase:'certpassphrase'
};
var err = null;
var apnConnection = new apn.Connection(options);
apnConnection.on('error', function(error){
  console.log("apscallback", 1, error);
});
apnConnection.on('transmitted', function(notification){
  console.log("apscallback", 2);
  console.log(notification);
});
apnConnection.on('timeout', function(){
  console.log("apscallback", 3);
});
apnConnection.on('connected', function(){
  console.log("apscallback", 4);
});
apnConnection.on('disconnected', function(){
  console.log("apscallback", 5);
});
apnConnection.on('socketError', function(error){
  console.log("apscallback", 6, error);
});
apnConnection.on('transmissionError', function(errorCode, notification){
  console.log("apscallback", 7, errorCode);
});
apnConnection.on('cacheTooSmall', function(difference){
  console.log("apscallback", 8);
});
function sendTestNotification() {
  var deviceToken = 'mydevicetoken';
  var myDevice = new apn.Device(deviceToken);
    var note = new apn.Notification();
    note.expiry = Math.floor(Date.now() / 1000) + 60; // Expires 1 hour from now.
    // note.badge = 3;
    // note.sound = "ping.aiff";
    // note.alert = "uD83DuDCE7 u2709 You have a new message";
    note.payload = {'message': 'somemessage', 'requester': 7};
    apnConnection.pushNotification(note, myDevice);
}
sendTestNotification();

http.listen(port, function(){
  console.log('listening on *:', port);
});

这是我的暴发户脚本的样子:

#!upstart
description "My Server"
start on started mountall
stop on shutdown
# Automatically Respawn:
respawn
respawn limit 99 5
env NODE_ENV=production
chdir /home/user/my-server/
exec node /home/user/my-server/server.js >> /var/log/my-server.log 2>&1

我得到的错误是:

...
apscallback 4
apscallback 5
apscallback 1 [Error: Socket unusable after connection. Hint: You may be using a certificate for the wrong environment]
... (REPEATS)

您确实在暴发户脚本中设置了env NODE_ENV=production(默认情况下,如果未设置,如果未设置该变量,APN 将违背测试/沙盒环境)。因此,这将与生产APN背道而驰。您是否有合适的证书来执行此操作(沙盒和生产证书不同)?

你的新贵脚本可能默认为 root。也许 root 的密钥环中没有正确的证书。尝试在暴发户脚本中隐式设置用户。

您应该能够使用setuid <username>
