Multiple instances?
Hi guys,
I'm currently preparing a migration of our Operating System which handle
our current tomcat installation from an OLD Linux using init scripts to a
CentOS7 release using sytemd.
Because I don't want to disturb the way the old server handle the webapps
(not yet :-) ), I have to start 2 separated instances of tomcat on the new
machine.
Using init script to boot multiples instance is quite easy, but know I'll
use systemd and I have to adapt.
I installed my OS and Tomcat from the CentOS repos, take a look at the
tomcat.service unit and tomcat-sysd script to see how the things work.
But now I'm a little bit disappointed, I don't understand how to have
multiple instances.
I created a tomcat@jcr.service unit file on my systemd directory and read
about the steps to achieve.
The first step said that *"by default SERVICE_NAME=tomcat. and must be
defined BEFORE tomcat-sysd is called"*
Well, OK, but how am I suppose to do that? Using environnement variables?
PreStartExec directive? Environnement directive?
I really don't get it, even looking at the tomcat-sysd wrapper script which
indicate me HOW the system run multiple instance don't help me to
understand WHERE am I suppose to put that information.
I understand that I have to create a new unit file, a new
/etc/sysconfig/tomcat file named according to the systemd unit, but I don't
get it about the SERVICE_NAME.
So if someone could help me a little bit, I'll be happy ^^

Hi Markt, my wiki alias username is ArKam and my Real username is
GaelTherond, thank you very much.
@Chris: Ok, thanks a lot for your explanations, it's crystal clear to me
now, as you said, it should be something specific to systemd as it reside
under the /etc/sysconfig/tomcat file which is use to set some variables to
start the JVM.
I'm working on a RHEL 7 right now instead of the CentOS from my first mail
as I'm cooking a new PROD server, the two distro use exactly the same
configs.

That's not surprising, since Tomcat uses the contents of server.xml to
configure the connectors, and does not look at any environment
variables for anything.
Where is CONNECTOR_PORT documented? I suspect it's something supported
by the systemd scripts simply to differentiate between various Tomcat
"servers" but doesn't have any bearing on the actual runtime
configuration. Remember that Tomcat can bind to an arbitrary number of
ports, so having a single CONNECTOR_PORT doesn't really make much sense.

That's expected behavior: it's possible that Tomcat is coming up with
no Connectors configured, and that some other software component will
then configure the connectors after the server is running. Think of an
embedded use-case and it becomes easier to understand how this would
not be an error.
> Shouldn't it be [using] the one specified by the CONNECTOR_PORT

No, Tomcat doesn't use environment variables for anything. The launch
scripts use a handful of environment variables to set up various
system properties when launching the JVM, and Tomcat uses those if
necessary.

Hi guys, thank for your informations regarding the Wiki, I've finally
managed to create my account ^^ (later is better than never as we said over
there :D) and as expected to add a new entry on the FAQ/HowTo I need to be
whitelisted or granted to edit mode, so if a moderator could add me it
would be nice.
PS: I've found something bizarre on the systemd init process regarding
Tomcat, if I set the CONNECTOR_PORT variable to something (let said 8081)
on the /etc/sysconfig/tomcat-${SERVICE_NAME} it is not use but rather
overrided by the tomcat server.xml file.
Until now, nothing strange, the weird part is that if I disable the
HTTP-BIO or AJP-BIO connectors values on this file tomcat load the unit
without binding any network port at all.
Shouldn't it be suppose tu use the one specified by the CONNECTOR_PORT
variable or did I missed something?

http://wiki.apache.org/tomcat/
Choose "login" at the top of the page and then choose the "you can
create one now" at the bottom of the page login page.
Once you have an account, I think you'll need to be white-listed to
actually make modifications. Just email a moderator or the whole list
to request write access to the Wiki.

Great. Care to post your systemd script template to the wiki? It will
likely help others trying to do the same thing.

hum.... OK many thanks for your hints, I got it, I understand what is going
on now.
Ok, I now have a clean and multiple instances running !!
Thanks to everyone!
@Mark Eggers: CentOS systemd units are not quite so far from the Fedora
ones. Personally I do love the way fedora and CentOS are working but I have
to confess that sometimes, and especially with tomcat everything is a pain
in the ass as they scatter the components everywhere in the system without
any (apparent) logics.
WTH with all this /usr/share/blabla ??
@Christopher: Many thanks for your advices, obviously it make more sens to
keep the catalina_base and derivate the catalina_home. I love this method!!
Once again, many thanks to everyone, I now have a clean and working server!

Fedora 21 has a relatively nice systemd script for Tomcat. It's
designed for running multiple Tomcat instances.
If you have a copy of Fedora 21 and yumdownloader (by installing
yum-utils), you can take a look at the system with:
mkdir Temp
cd Temp
yumdownloader tomcat.noarch
rpm2cpio tomcat-7.0.54-3.fc21.noarch.rpm | cpio -idmv
All of the files are then accessible in the Temp directory.
I've never liked how Fedora / RedHat / CentOS scatter the components
all over the landscape. I'm thinking of adapting the Fedora systemd
scripts to work with Tomcats installed under a particular user.
The only issue seems to be that the SHUTDOWN_WAIT (time to wait in
seconds before killing the process) is documented not to work.
Sadly, I have some truly misbehaving applications that sometime need a
kill -9 on the underlying Tomcat. Those misbehaving applications are
unlikely to be fixed.
My init scripts take care of this by issuing an orderly shutdown
command, waiting up to SHUTDOWN_WAIT seconds (checking every second),
then issuing a kill -9 if the process still exists.
. . . better late than never (mostly)

You should not have to copy the whole CATALINA_HOME. Instead, create a
CATALINA_BASE (which is basically just a few directories and a few
configuration files) for each service and then set the CATALINA_BASE
environment variable to point to each one for each service, set
CATALINA_HOME to point to where the full installation of Tomcat is
(with no web applications installed in it), and each service should
operate independently.
So you should be able to have something like this:
SERVICE_NAME=tomcat-one
CATALINA_HOME=/opt/apache-tomcat-7.0.57
CATALINA_BASE=/opt/tomcat/tomcat-one
SERVICE_NAME=tomcat-two
CATALINA_HOME=/opt/apache-tomcat-7.0.57
CATALINA_BASE=/opt/tomcat/tomcat-two
Then you configure /opt/tomcat/tomcat-(one|two) to have the
configuration and applications you want.
You should be able to start tomcat-one and tomcat-two independently of
each other. I don't know exactly what systemd does with all of this,
but once you end up calling catalina.sh with the right environment
variables set, Tomcat will do the right thing.

Ok soooo, here is a small update.
I've finally found what does this SERVICE_NAME mean, indeed you have to
copy the original unit, then add the Systemd's directive
named Environment like this:
Environment="SERVICE_NAME=<YOUROWNSERVICENAMEHERE"
then you will copy the default tomcat config file found on the
/etc/sysconfig directory.
And as you supposed it Cristophe and Daniel, you then have to copy the
whole CATALINA_{HOME/BASE} or update the previous config file to point out
to another tomcat installation.
I hope it would help someone ;-)

When you get something working, please share your solution :)
I'm interested to see what you work out and I'm sure others will be as well.

Ok, then I'll completly wright another systemd unit derivated from the one
provided by CentOS.
Yup, that what I thought about the CATALINA_HOME and BASE, so as you
suggested, I'll test to run individual units and saw how it's going on.
Many thanks guys.

Starting different instances of Tomcat is mostly just a matter of setting
the CATALINA_HOME and CATALINA_BASE environment variables to the right
locations. I'm sure systemd has a way for you to set environment
variables, so that should be sufficient to start different instances.
For more details on CATALINA_HOME and CATALINA_BASE, check out the
RUNNING.txt file in your download or look here.
http://svn.apache.org/viewvc/tomcat/tc7.0.x/trunk/RUNNING.txt?view=markup
I'd suggest getting everything working with multiple instance first. Once
you can start the instances from the command line then worry about starting
them with systemd.

Hi Christopher,
Many thanks for your answer, well, I'm pretty comfortable with systemd
myself as I rely on it for my Fedora box for a long time ago, but on this
particular topic regarding tomcat, I don't really understand the purpose of
this special sentence.
As you pointed it, for me too usually caps names == env variables but as on
the tomcat-sysd script it's simply called without futher sources I'm not
quite sure for now.
Well, lets see if another *NIX Admin already had started multi-instances
tomcat on systemd distributions :D
Another way would be to completly duplicate the tomcat directory and
service unit and start both at runtime but... doesn't seems too shiny for a
new server :D

Hrm. Good luck getting help with systemd. The ASF doesn't even support
init.d scripts, though I'm sure many *NIX admins here can help with
init.d scripts (including myself). systemd is a bit new, to ... we'll see.

I have no idea. Generally, whenever I see something in ALL_CAPS that
needs to be set to a value, it's an environment variable. With
systemd, it could mean just about anything.

Ultimately, it will all boil down to CATALINA_BASE and CATALINA_HOME
as far as Tomcat is concerned. The SERVICE_NAME is probably a
systemd-only thing.
