Question

我想使用Masakari项目为我的Openstack实例创建实例HA，该项目在控制器节点以及masakari-api，masakari-engine和masakari-processmonitor上安装了masakari-instancemonitor和masakari-hostmonitor openstack-nova-compte在计算节点上，但是当我要测试失败的2019-02-02T10:10:03.782541+03:30 c2 masakari-processmonitor: Command: systemctl restart openstack-nova-compute.service 2019-02-02T10:10:03.782972+03:30 c2 masakari-processmonitor: Exit code: 1 2019-02-02T10:10:03.783363+03:30 c2 masakari-processmonitor: Stdout: u'' 2019-02-02T10:10:03.783785+03:30 c2 masakari-processmonitor: Stderr: u'Job for openstack-nova-compute.service failed because the control process exited with error code.

我检查到控制器节点和计算节点的连接，都正常。
我检查Rabbitmq队列，它具有masakari ha-engine队列。
我检查了masakari数据库的MySQL，我也有。

    router.post('/register', function(req, res) {
  var name = req.body.name;
  var email = req.body.email;
  var username = req.body.username;
  var password = req.body.password;
  var password2 = req.body.password2;

  req.checkBody('username', 'Veuillez renseigner un identifiant').notEmpty();
  req.checkBody('email', 'Veuillez renseigner une adresse email valide').isEmail();
  req.checkBody('password', 'Veuillez renseigner un mot de passe').notEmpty();
  req.checkBody('password2', 'Les mots de passe ne correspondent pas').equals(req.body.password);

  var errors = req.validationErrors();

  if (errors) {
    res.render('register', {errors:errors});
  } else {
    User.findOne({ email: email }).then(user => {
      if (user) {
        res.render('register', {errors:errors})
        req.flash('error_msg','Adresse email non dispo')
  } else {
        var newUser = new User({
            email:email,
            username: username,
            password: password
        })
     User.createUser(newUser, function(err, user){
      if(err) throw err;
      console.log(user);
    })

    req.flash('success_msg', 'Vous venez de créer un compte, vous pouvez désormais vous connecter');

    res.redirect('/users/login');
  }
})
}})

每件事看起来都正确，但是我的问题在哪里，我会错过一些事情吗？

Answer 1

问题似乎是

AttributeError：“连接”对象没有属性“ instance_ha”。

在稳定版/女王区中，此问题已由this patch解决。

如果您仍然在稳定版/女王或其他任何版本中发现此问题，我建议您通过launchpad向OpenStack masakari-monitor提交错误报告。请提供OpenStack版本详细信息。

openstack masakari，AttributeError：“连接”对象没有属性“ instance_ha”
