Deploying application to server

Hi there,

I have problem with deploying application to remote server. My application works correctly on my local machine, but when I load it via Monticello to my server and create site with these commands:


name := 'pokus'.
hostname: 'aida.nigol.cz'. "add in your DNS first!"
ip := 'aida.nigol.cz'.
styleClass := 'WebStyle'. "change if you provide your own subclass"

AIDASite newNamed: name.
(AIDASite named: name) host: hostname ip: ip port: 80.
(AIDASite named: name) styleClass: styleClass.
SwazooServer startSite: name.

pokus := PAPokus new  "root domain object"
(AIDASite named: 'mysite') addUserService: pokus named: #myPokus
(AIDASite named: 'mysite') urlResolver defaultURL: '/pokkus.html' forObject: pokus



it doesn't work as expected. After visiting site at http://aida.nigol.cz/pokus.html browser try to load http://aida.nigol.cz/admin?view=login and after that, debugger in image is fired up on halt. Is there some other magic which I'm not aware of? :)
BTW. I'm hosting on Amazon's EC2 micro instance and everything seems to be alright including VNC access.

Thanks.
Martin

Ahoj Martin,

Is the login an expected behavior? What is a stack trace of that halt?

Self halt is namely a way to raise an exception when occurs in Aida on
Squeak/Pharo, well, once we will make this better :) That is, there is
some error in your or Aida code, that it the reason for that halt and we
need a full stack to find a reason.

Best regards
Janko

I think so, because on local machine, login is showed too. Correct me if I'm wrong, by default every page in application is accessible only after one log in as admin, right? But I'm not sure, how to deal with these user privileges, so I'm not able to set my application visible for everyone.

I'm almost sure, that problem is in my code :). I'm appending content of PharoDebug.log at end of this mail.

Hi Martin,

Bravo, you found a bug in Aida :) It is in WebStyle and because a
DefaultWebStyle is used in aidademo, noone noticed :) But in any case it
is better to use a DefaultWebStyle instead, until you won't do your
completely own "styling". So, by changing the style class it should work.

About security, login as admin, click Security down in navigation, tab
Groups, click AllUsers, then for access without limits click Access
rights, then your App classes and set View all to them.

Best regards
Janko

Ok, that's my first "contribution" to Aida :) Your suggestion helped and everything working great now. I must now in spare time figure out, how to create my own style (subclass WebStyle and explore, how the DefaultWebStyle is implemented).

Great, works too :).

Other story is the way, how Aida with Swazoo act as server. I like it much more than Seaside's Kom with for example Apache. Now I have only Pharo image with Aida on my server and I'm perfectly able to handle all that virtual names stuff completely with Smalltalk via VNC. That's a big difference with my Seaside deployment scenario, where I must handle all this configuration by editing Apache's config files to create proxy to the Seaside's image. And that's really boring.

Virtual serving of many Aida websites together with static content is
indeed very neat and useful feature. You can deploy a new site in a
minute! Even a whole image can be deployed by just loading the code and
setting host:ip:port: combo in few minutes.

On VisualWorks Swazoo works great as a standalone web server while on
Pharo it seems that a "Sockets not closing" [1] bug can have problems.
But Pharo guys are aware of it and hopelly they will resolve it soon. I
also need Swazoo on Pharo working well, so cosider that problem almost
solved :)

What will be very nice contribution would be an article, something like
"Deploying Aida in the Cloud". As a blog post or as a docs page on our
website. What do you think?

Do you mind this bug is present in Squeak too, or it is only Pharo related? Is this a big problem with real life websites?

That's good idea. I don't have a blog, so documentation page on Aida's website should be better option. But I'm not sure, if I'm the right guy to do this :) I have very little experience with Aida now. I'll try to write something when time allows me, but I can't promise anything.

Don't know exactly. Squeak website for instance run Swazoo for years,
but it is behind Apache, which probably care about proper closing of TCP
connections. While when you are directly on the net, many things can
happen. In any case, from the discussion on mentioned thread you can see
the promise, that problem will be solved soon. So I don't panic yet

Most people have an opinion that such setup is complex, that's why your
experience of simplicity is even more important. I can open you an
account on the website to start writing when you'll have time ...

Hi Janko,

I have been using Apache and virtual hosts to redirect incoming requests to the various sites in an image (each of which is listed in my hosts file with a name and port). If I remove Apache, how do I tell Swazoo to redirect to the various sites?

First you need to run the image as root if you are on Linux. Root is
namely needed to run on port 80. This has security implications of
course, so be careful. Chroot jail is one of possible protection here.

Then you simply set host:ip:port: of your sites accordingly. Let me
explain by concrete example of my hosting of Aida and Swazoo websites,
which are both run from same image and on same public IP. Those two
sites are set with:

  (AIDASite named: 'aida-site')
        host: 'www.aidaweb.si' ip: 'hosting-biart.eranova.si' port: 80.

  (AIDASite named: 'swazoo-site')
        host: 'www.swazoo.org' ip: 'hosting-biart.eranova.si' port: 80.

All those DNS names must be registered on some DNS server. Just
registering them in hosts file is not enough for serving outside your
machine.

hosting-biart.eranova.si is the public IP for hosting mostly customer
BiArt (commercial product) websites, from there that name, but also many
public websites. Currently 70 websites are open on this image, 20 of
them enabled, around 10 pretty active.

Hope this help.

Best regards
Janko

That's great Janko, running as root and setting them all to port 80 was what I had not figured out.

Thanks a lot.

I have been using Apache and virtual hosts to redirect incoming requests
to the various sites in an image (each of which is listed in my hosts
file with a name and port). If I remove Apache, how do I tell Swazoo to
redirect to the various sites?

First you need to run the image as root if you are on Linux. Root is
namely needed to run on port 80. This has security implications of
course, so be careful. Chroot jail is one of possible protection here.

Then you simply set host:ip:port: of your sites accordingly. Let me
explain by concrete example of my hosting of Aida and Swazoo websites,
which are both run from same image and on same public IP. Those two
sites are set with:

  (AIDASite named: 'aida-site')
	host: 'www.aidaweb.si' ip: 'hosting-biart.eranova.si' port: 80.

  (AIDASite named: 'swazoo-site')
	host: 'www.swazoo.org' ip: 'hosting-biart.eranova.si' port: 80.

All those DNS names must be registered on some DNS server. Just
registering them in hosts file is not enough for serving outside your
machine.

hosting-biart.eranova.si is the public IP for hosting mostly customer
BiArt (commercial product) websites, from there that name, but also many
public websites. Currently 70 websites are open on this image, 20 of
them enabled, around 10 pretty active.

Hope this help.

Other story is the way, how Aida with Swazoo act as server. I like it much more than Seaside's Kom with for example Apache. Now I have only Pharo image with Aida on my server and I'm perfectly able to handle all that virtual names stuff completely with Smalltalk via VNC. That's a big difference with my Seaside deployment scenario, where I must handle all this configuration by editing Apache's config files to create proxy to the Seaside's image. And that's really boring.

Virtual serving of many Aida websites together with static content is
indeed very neat and useful feature. You can deploy a new site in a
minute! Even a whole image can be deployed by just loading the code and
setting host:ip:port: combo in few minutes.

On VisualWorks Swazoo works great as a standalone web server while on
Pharo it seems that a "Sockets not closing" [1] bug can have problems.
But Pharo guys are aware of it and hopelly they will resolve it soon. I
also need Swazoo on Pharo working well, so cosider that problem almost
solved :)

What will be very nice contribution would be an article, something like
"Deploying Aida in the Cloud". As a blog post or as a docs page on our
website. What do you think?
