by the way, has anyone read that article about nginx tcp load balancing being added to the open source version?

ruaok, possibly, yeah

address already in use? that's an odd error.
2015-04-24 11433, 2015
-
ruaok
yes.
2015-04-24 11451, 2015
-
ruaok
especially since most of those ips doesn't exist.
2015-04-24 11427, 2015

kepstin-laptop
is there something in the config that's listening to *?
2015-04-24 11459, 2015

ruaok
da fuq?
2015-04-24 11411, 2015

ruaok
that problem goes away and nginx starts fine after a chef provision.
2015-04-24 11421, 2015
-
ruaok
but right after boot. no go.
2015-04-24 11422, 2015
-
kepstin-laptop
i mean, is there anything in the nginx config with "listen 80" or "listen *:80"?
2015-04-24 11439, 2015
-
Leo_Verto
why would that bind addresses though?
2015-04-24 11408, 2015
-
kepstin-laptop
that shouldn't...
2015-04-24 11417, 2015
-
kepstin-laptop
ruaok, hmm, i wonder if nginx is being started twice
2015-04-24 11422, 2015
-
ruaok
conf/sites-available/default: listen 80;
2015-04-24 11427, 2015
-
kepstin-laptop
maybe the ubuntu init script *and* daemontools?
2015-04-24 11404, 2015
-
ruaok
shit, that is it.
2015-04-24 11411, 2015
-
ianmcorvidae
that's likely, if you haven't disabled the init-script one
2015-04-24 11418, 2015

ruaok
my script is supposed to removed those links.
2015-04-24 11450, 2015

I bet the

yeah, the debian packages will be running 'update-rc.d' to make sure the rc.d symlinks are all present
2015-04-24 11452, 2015

ruaok
oh.
2015-04-24 11419, 2015
-
ruaok
I remove the K links, not the S links.
2015-04-24 11430, 2015
-
ruaok
what is the command to remove these links?
2015-04-24 11432, 2015
-
Leo_Verto
why not just use sudo update-rc.d -f nginx disable?
2015-04-24 11435, 2015
-
ruaok
I'm currently doing it by hand
2015-04-24 11437, 2015
-
ruaok
"hand"
2015-04-24 11448, 2015
-
ruaok
Leo_Verto: that :)

Leo_Verto
:D
2015-04-24 11418, 2015
-
kepstin-laptop
you might want remove, not disable
2015-04-24 11430, 2015
-
kepstin-laptop
otherwise it'll actually run the init script stop at boot
2015-04-24 11407, 2015
-
Leo_Verto
disable is pretty explicit though
2015-04-24 11418, 2015
-
ruaok
Leo_Verto that is pretty much what I want.
2015-04-24 11421, 2015
-
ruaok
ok, doing another reboot test.
2015-04-24 11431, 2015
-
ruaok
nginx, which is being managed to daemontools is not being started at boot time.
2015-04-24 11436, 2015
-
ruaok
starting it by hand and all is well.
2015-04-24 11407, 2015
-
ruaok
rvedotrc: hopefully my last question for you for tonight.
2015-04-24 11415, 2015
-
ruaok
the "down" file exists in the ngxing repo.
2015-04-24 11430, 2015
-
ruaok
which is preventing it from starting.
2015-04-24 11441, 2015
-
ruaok
but carl uses the same repo, yet nginx starts at startup.
2015-04-24 11448, 2015
-
ruaok
any idea what is with that?
2015-04-24 11429, 2015
-
rvedotrc
"down" means "when supervise starts, don't also start the service" - i.e. wait to "svc -u".
2015-04-24 11449, 2015
-
rvedotrc
So the question is, what is meant to control that service (svc -d/-u)?
2015-04-24 11404, 2015
-
rvedotrc
Probably haresources, I suspect.
2015-04-24 11422, 2015
-
rvedotrc
(or whatever it is under corosync)
2015-04-24 11432, 2015
-
rvedotrc
So... not sure if that helps. I haven't understood corosync etc yet.
2015-04-24 11441, 2015
-
ruaok
it does.
2015-04-24 11455, 2015
-
ruaok
which plays back into what kepstin-laptop was saying -- nginx should be managed by corosync.
2015-04-24 11422, 2015
-
ruaok
kepstin-laptop: how does one setup nginx to be started by corosync?
2015-04-24 11425, 2015
-
rvedotrc
That's the way I chose to set it up. Other ways may be possible.
2015-04-24 11459, 2015
-
kepstin-laptop
ruaok, it has a native nginx service module; i'm not sure if that's compatible with your config
2015-04-24 11442, 2015
-
ruaok
can we get corosync to issue the "svc -u" command as a generic command?
2015-04-24 11446, 2015
-
kepstin-laptop
2015-04-24 11456, 2015
-
kepstin-laptop
which apparently can manage stuff via daemontools
2015-04-24 11442, 2015
-
rvedotrc
You can probably use either the packaged nginx (/etc/nginx/nginx.conf or whatever), or daemontools. Probably not both.
2015-04-24 11420, 2015
-
ruaok
rvedotrc: yeah, we already disabled the packaged nginx startup. I want to continue to use daemontoosl
2015-04-24 11422, 2015
-
rvedotrc
If you wanted to you could do crazy stuff with binding to non-local IPs. But, I went for simple: use HA to add IP, then start nginx.
2015-04-24 11453, 2015
-
ruaok
rvedotrc: yep, and that seems to be the right way of doing things/
2015-04-24 11426, 2015
-
ruaok
kepstin-laptop: that script you linked -- how does that get tied into corosync?
2015-04-24 11434, 2015
-
kepstin-laptop
the native nginx module shipped with this stuff manages everything itself; just pass it the path to nginx and the nginx config
2015-04-24 11456, 2015
-
kepstin-laptop
ruaok, that would be dropped into /usr/lib/ocf/resource.d/ngyuki/daemontools
2015-04-24 11410, 2015
-
kepstin-laptop
then you'd configure it as 'crm configure primitive nginx ocf:ngyuki:daemontools params service_dir/path/to/nginx/service or so.
2015-04-24 11413, 2015
-
ruaok
"just pass it the path to nginx" -- from where?
2015-04-24 11428, 2015
-
kepstin-laptop
er, service_dir=...
2015-04-24 11446, 2015
-
kepstin-laptop
and add colocation and order constraints
2015-04-24 11413, 2015
-
kepstin-laptop
in crm configure: "colocation colo-ips-nginx +inf: webserver failover-ips" and "order order-ips-nginx Mandatory: failover-ips nginx"
2015-04-24 11452, 2015
-
ruaok
2015-04-24 11408, 2015
-
ruaok
that would be added to the corosync setup notes
2015-04-24 11439, 2015
-
kepstin-laptop
yeah, that looks right
2015-04-24 11424, 2015
