I don't :)

I think the best way is to use the Launch Deamon facility of macos.
Briefly, as root:

1. Create a file
/Library/LaunchDaemons/org.apache.tomcat.startup.plist with all the
appropriate settings
2. run "launchctl load -w
/Library/LaunchDaemons/org.apache.tomcat.startup.plist"

To remove the load-on-start:

3. run "launchctl unload -w
/Library/LaunchDaemons/org.apache.tomcat.startup.plist"

Building (and running) Tomcat on MacOS

[Christopher Schultz]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA256

All,

Periodically, some folks ask how to get Tomcat running on MacOS. In
order to fully-test the most recent version of Tomcat 8.5.x being
voted on, I built a new environment on my Mac from scratch and
documented everything.

I put all of my notes into the Tomcat Wiki which can be found here:
https://wiki.apache.org/tomcat/Building%20Tomcat%20on%20MacOS

Comments and modifications are welcome. It would be even better if
some folks with Macs who aren't running Tomcat would actually try
following the instructions and let me know if anything in particular
doesn't work for you.

Unicast is possible, but much less flexible.

You ought to be able to scp to the right place from outside the box.
If you can do that, just scp from the deployment server (just pick
one) to each of the others. Be sure to check to see which servers
successfully deployed the application. If any of the servers fail to
deploy the new version, "downgrade" the servers that succeeded by
"upgrading" them to the old version (which, presumably, will
successfully deploy the old version).

For my money, if you've got a cluster I'd try to use the FarmWebDeployer
.

We had some conversations about the FarmWebDeployer this week at
TomcatCon. This component has always had an air of untrustworthyness
to it, and not many people have tried it for one reason or another.

Honestly, I'd like to have MORE people use it because then it could
get some real-world usage, and some real-world feedback. If it does
indeed work and is robust, then that's great. Otherwise, we (Tomcat)
should either fix the bugs and make it useful or kill it off so nobody
relies upon it.

So if you are willing to plough-through it, please do so and we'll try
to provide the best support we can.

CATALINA_OPTS; I will change and test it.
Macos is 64-bit and you almost certainly have a 64-bit JVM. 64-bit
JVMs are *always* running in "server mode" so that's probably not
necessary.

There are other environment variables you can use to set the file
encoding, but an explicit system property is probably the best way to
do it.

In your case, CATALINA_OPTS or JAVA_OPTS would be fine.

Most people use system properties for setting the size of their heaps.
They set JAVA_OPTS to "-Xmx16G" and never realize that this means that
"catalina.sh stop" will launch a JVM with a 16 GiB heap just to send
the "shutdown" command to Tomcat.

I typically run 4 separate applications, and I run them in completely
separate JVMs on the same server. I do this mostly to make deployments
easier and more flexible... I can test/deploy each application
separately and upgrade either them, their supporting Tomcats, or their
supporting JVMs separately from the rest.

Leon is correct that, given a set of reliable web applications, you
should be able to run them all in one large JVM. Theoretically,
running a single JVM will give you the best resource utilization since
you don't pay a penalty for separate memory spaces for the same kinds
of things (i.e. the JVM doesn't have to take up 2x memory because of
the two processes running). In reality, (a) applications have bugs,
(b) JVMs have bugs, (c) threads sometimes have stack-overflows, and
(d) JVMs use shared memory to avoid huge amounts of memory for each
independent JVM.

I find that I get more flexibility from a multi-JVM deployment even
though my applications seem to be very well-behaved and I generally
deploy everything on the same Tomcat version and JVM version.

Only if your application can't utilise resources properly. If your
application fails to scale, fails to use all available cores or memory, you
should have multiple instances. Also if your total memory is insanely high,
like way above 64 Gb, you'd be better off with multiple instances. Also if
your app uses a lot of synchronisation, having multiple tomcats can help.
However, all of that is pretty improbable with a mac mini.
Rule of thumb: if you can bring your app with tomcat to near 100% CPU or
memory usage, no need for multiple instances.
HTH

P.S. kudos to you for hosting on macs ;-) Crazy but fun ;-)

Re: Tomcat on macOS

[Israel Timoteo]

All,

Thanks for your replies, very good information.


Christopher,

Let me share additional information about my environment: 

1) All my servers, production and non-production, are hosted at two data 
centers (different locations) with a third-party company (A)
-Server specs: Mac mini, 16 GB memory and 1 TB HD

2)There is one Tomcat instance per server and all Tomcats are in a cluster, 
having HTTPD in front
-on HTTPD, mod_jk is used
-one cluster per each location, multicast is used - I do recall a presentation 
where not using multicast was mentioned - I need to check my notes 

3) The application is developed by a third-party company (B) and uploaded to 
one of my non-production servers

4) When an application needs to be deployed, I connect (ssh) to the target 
server(s) and from there, I use scp to get the war file from the non-production 
server and place the war file into a particular directory; then, I have a 
script that moves the war file to $CATALINA_BASE and do some additional 
validations
-Autodeploy and Parallel deployment are used
-I explored the FarmWebDeployer option years ago but had the war file removed 
from the cluster when the master node was down… maybe I had a wrong 
configuration then.. so I will need to check this option again and experiment

5) As per the JAVA_OPTS…
-I use it for “-server -Dfile.encoding=UTF-8”
-It seems that I can add “-server -Dfile.encoding=UTF-8” to CATALINA_OPTS; I 
will change and test it.



I have an additional question:

1) Would there be any recommendations for not having one Tomcat instance per 
physical server?

Re: Tomcat on macOS

[Mark Eggers]

Folks,

Beware, the following is extremely ugly Groovy. I've changed the names
to protect the guilty (I think).

Also, the *_SVR and *_URL values are environment values stored centrally
in Jenkins. That way they can be changed easily. They also show up in
the job logs, which means with a little scripting effort I can get a
history of what versions were deployed to what server when.

Please review and laugh . . . or better yet, proffer improvements :-).

Doesn't this require a cluster (and therefore multicast)? That becomes
challenging in a cloud environment where there's no multicast easily
available.

This would be nice with a little scripting.

What I do is use Jenkins, Maven, Nexus, and a little Groovy scripting.

1. Maven with the Tomcat Maven Plugin [1]

The WAR file is customized (context.xml) based on the target environment.

2. Jenkins

The build is run by Jenkins, and the build number (with a little 0
padding via a Groovy script) is tacked onto the WAR name as app##nn.war.

This allows the parallel deploy feature to be used [2].

3. Nexus

This is where all of the base artifacts are stored. Nexus 2 is used
currently since Nexus 3 doesn't have the REST API needed to cleanly
interact with the Jenkins job via a Groovy script. Maybe I should learn
how to write a Nexus plugin to get lists of artifact versions via REST . . .

4. Groovy scripting

Groovy is used in Jenkins to do the following:

a. Query Nexus to get a list of artifact versions
b. Prevent non-production artifacts from landing on production platforms
c. Create the final number for parallel deployment

To expand this to multiple machines, a set of pipeline jobs could be
created.

a. Build the customized WAR for the target environment
b. Multiple jobs deploy to the servers in the target environment
c. Multiple jobs validate the deployment
d. Final job sends mail to interested parties with success / failure

I know that's a lot of infrastructure. There are certainly things that
could be done differently. Ant (with Ivy), or gradle could be used for
the builds. A different repository manager could be used (other than
Nexus). A different CI / CD system could be used (other than Jenkins).

Anything that meets at least the following requirements could be strung
together.

a. Reliable place to get the WAR file you need to deploy
b. Reliable build system that can be automated
c. Build system that can deploy to Tomcat
d. Testing that the deployment actually worked
e. Notification

The end result is that some authorized person can log into Jenkins,
select a version of an application to deploy, deploy it to the target
environment, know that it's been successful (or not), and have
notifications automatically sent out.

I am using neither of these strategies, but...

a. FarmWebDeployer [1]
b. Auto-deploy + scp

Why in the world are you deploying a web application to 20+
macos-based servers? Or do you have a Macos client and 20+

JAVA_OPTS is only required if you require any java opts. Do you
require such options? Usually, when people set JAVA_OPTS they really
want to set CATALINA_OPTS instead.

Thank Thad!


Any comments from the community for ...

1) What tools is the community using for simultaneous applications deployment 
on several servers, let’s say more than 20?

4) Is JAVA_OPTS required?

On #2 and #3, setup up separate CATALINA_HOME and CATALINA_BASE directories
as described in RUNNING.txt. This will keep logs out of CATALINA_HOME and
make upgrading to new releases of Tomcat fairly easy.

My Macs aren't production, so you may need to adapt this. I unpack Tomcat
releases to /Library/Tomcat. I remove all but ./bin and ./lib, and rename
./conf to ./conf-ORIG. I diff this ./conf-ORIG with the ./conf-ORIG from
the last release, making tweaks to my $CATALINA_BASE/conf files as
required. Then I create a link

$ cd /Library/Tomcat
$ tar zxvf ~/Downloads/apache-tomcat-8.5.11.tar.gz
... // remove subdirectories...
$ rm catalina
$ ln -s /Library/Tomcat/apache-tomcat-8.5.11 catalina

and in ~/.bash_profile `export CATALINA_HOME=/Library/Tomcat/catalina` (I
also set CATALINA_HOME and CATALINA_BASE in my org.apache.tomcat plist).
Now restart Tomcat.

Tomcat on macOS

[Israel Timoteo]

Hi all,

My environment is Tomcat 8.5.12, Java 1.8.0_112 running on macOS 10.12 and 
planning to update Tomcat to 8.5.15.

I’m wondering if I can get comments from the community for my questions below?


1) What tools is the community using for simultaneous applications deployment 
on several servers, let’s say more than 20?

2) Would having the logs located outside of the Tomcat home directory, if 
possible, affect Tomcat operation?

3) Are there any recommendations/best practices for installing and running 
Tomcat 8.5.15 on macOS 10.12?

4) Is JAVA_OPTS required?



Thanks for your comments.
