Also, a good question for anyone interested: portage doesn't have tomcat 4.1.x anymore, OpenNMS needs it or now (tomcat 5.x support is in the works). Should I:

a) pull the tomcat 4.1.x-latest from the portage cvs and stick in my overlay to make it easy to use
b) tell people where to go figure all that out
c) detect if people has tomcat 4.1.x install already and if not warn them about their predicament and do a headless install?

And in a fit fuelled by much fine Dalwhinnie, a more cruft-free version that actually runs nicely can be found here:

And now, for the 5:14am "Bedtime Edition", which another ton of small niggles fixed, and also a stab at a nice Gentoo-ified init-script wrapped up nicely:

http://portage.boxed.no/net-analyzer/op ... -r5.ebuild

Feel free to mail me and bug me with stuff that doesnt work properly

Also a quick tidbit of info for those reading the thread, according to the gods that be in the OpenNMS world, work is goig to happen soon-ish on getting it over to tomcat 5.x, so taht will solve that missing link.

My ebuild will build as is without tomcat 4.1.x, as it is only the web-app stuff that cannot be installed without tomcat 4.1.x. It contains pointers to getting this working if you have your own tomcat 4.1.x or the old one from portage, if not it stays quiet abou tomcat.

Also, to make it easy on people I've made the ebuild as easy to build as possible, plenty of good information, and I've tried to filter out and only print things of relevance, depending on what you have on your system. Especially pay attention to the one big thing up front, when emergeing, telling you to make sure your postgresql is initialised. I stuck this one in here since many will probably just emerge opennms-server and then have postgresql pulled in from the same dependancies, and this have a cold and non-initialised postgresql.

I am managed how to get working tomcat5 and opennms-1.2.4 togever. No additional configuration of server.xml, just add to tomcat-users.xml:

Code: Select all

  <role rolename="OpenNMS RTC Daemon"/>
  <role rolename="OpenNMS Administrator"/>
  <role rolename="OpenNMS User"/>
  <user username="rtc" password="rtc" roles="OpenNMS RTC Daemon"/>
  <user username="admin" password="admin" roles="OpenNMS Administrator,OpenNMS User"/>

copy opennms.xml to /etc/tomcat5/Catalina/localhost/ , and set right permissions on all OpenNMS staff.
I used opennms ebuild from bugzilla, just changed version number and tomcat from portage.

Please excuse my bad english.

Thanks for the followup. I have a 1.2.4 with tomcat 5 build im testing here, I have a handfull of issues witht he older ebuilds as well, and will adress most of these this weekend.

ator · Post by **ator** » Fri Sep 16, 2005 12:00 pm

Oh, forgot to mention. Delete line about authentication from opennms.xml

Code: Select all

<Realm className="org.opennms.web.authenticate.OpenNMSTomcatRealm" homeDir="/opt/OpenNMS" />

Hi ahoogerhuis,

I look forward to seeing your 1.2.4 + tomcat 5 ebuild. I'll test it as soon as I see it on bugs.g.o. Just a quick note to make the ebuild a bit more future proof:

I would replace your use of xargs with find's -exec switch. It is safer to use (albeit slower) because xargs doesn't escape odd characters or spaces (by default, at least).

So replace this:

Code: Select all

find ${D}/${INST_SHAREDIR} -type d | xargs chmod 750

with this:

Code: Select all

find ${D}/${INST_SHAREDIR} -type d -exec chmod 750 {} \;

You can read this post or this page for a more thorough description.

I was about to be killed in trying to use the ebuild for tomcat 4 and opennms. I was scared by the installation manual to not to build from source. At last I decided to give a try and everything worked like charm (almost!:) So, I just wanted to share my successful installation of OpenNMS w/ Tomcat 4 & Postgresql 7:

- Download all files in http://portage.boxed.no/net-analyzer/opennms-server/ and place them in your portage overlay dir (i.e. /usr/local/portage/net-analyzer/openms-server/)
- Run emerge -avo opennms-server and have a look on the packages needed to be installed. If you get a very long list be mindful of the USE flags. Basically you need all the dev-java packages and the j2sdk that needs to be downloaded manually from java.com.
- Run emerge -avt "<postgresql-8". I decided not to use version 8 because I thought tomcat 4 may work better with an older version.
- Run emerge --config postgresql
- Download the tarball of the binary package jakarta-tomcat-4. I used version 4.1.30, and untarred it in /opt and created a symbolic link /opt/tomcat.
- Download the OpenNMS source and untar it in /usr/local/src.
- Create a build.properties file where is build.xml and place in it these two entries:
install.dir = /opt/opennms
build.postgresql.include.dir = /usr/include/postgresql/server
- Follow the Installation guide of OpenNMS about "Customizing Tomcat 4", "Customizing postgresql.conf", "Customizing pg_hba.conf", "Building from source" and "Installing from source"
- For the rc script of tomcat and opennms I placed everything in /etc/conf.d/local.start and /etc/conf.d/local.stop

Hope it will help! Happy monitoring!

OK, I've risen fro the dead and fixed things more. I spoke ot one of the dev of OpenNMS and they folded the tomcat 5 bits that are neede dinot the upcoming 1.2.8, and I've rolled it up in a new ebuild, also squasing a few bugs.

- we now know we can run on PostgreSQL 8.0.x at least.
- we can run with tomcat 5.0.x nicely
- many small typos fixed
- untill OpenNMS is released in a few weeks or so, it will have the SRC_URI pointing at a tarball on one of my machines, called 1.2.8-1, this is *NOT* the full 1.2.8, but 1.2.7 pluss the tomcat 5 bits. once 1.2.8 is shipped I'll bump the version and off we go again, with source from sf.net.

For now, you should be able to merge tomcat 5, then merge opennms, and all should be swell.

Any problems, give me a shout, and also, one problem I'm not sure how to deal with: at the end of the ebuild install I do amny checks to see fi you have tomcat, that postgresql i setup nice and all such tings, but all the messages I print get wiped off by the unmerging og the older version on upgrading. Is there any way to deferr these messages?

Thank you, man!
I'm eager to try the new ebuild. However my server is in production, so I will give a try (as soon as I will have time!) on test server and see if it works!

I'll keep you posted.

I've had some housecleaning and the OpenNMS can now be found here: http://portage.boxed.no/net-analyzer/opennms/

I've seen some people attempt to access the old openms-server dir, but that's not there anymore.

mlaccetti · Post by **mlaccetti** » Sun Apr 16, 2006 4:04 am

Busy emergin'g it right now.

Any ideas as to upgrading to use Tomcat 5.5? Or is that something to take up with the devs themselves?

Edit:
And if you need a mirror for your file, let me know...

I wanted to use opennms too.

For this kind of thing it is strongly recommended to use a dedicated host.

As it will only run opennms the distribution used is not that important IMHO, the only interesting criteria i found was being supported by the project. Support being definitiely a plus, i choosed a supported distro (centos4) over gentoo.

Hi,
I use the opennms ebuild, but after starting pgsql, tomcat and opennms I get the following when I try to connecto to localhost:8080/opennms

Code: Select all

HTTP Status 404 - /opennms/

type Status report

message /opennms/

description The requested resource (/opennms/) is not available.
Apache Tomcat/5.0.27

I looked at the installation docs and the opennms.xml, server.xml and work directory are fine.

do you have any idea on how to solve this ? tomcat test index.jsp page works fine

thanks

I have OpenNMS installed (thank you very much for the ebuild). My issue is that I can't log into the web interface. http://localhost:8181/opennms and it prompts for HTTP authentication. I tried

user: admin
pass: admin

but this does not work. I tried other obvious combinations of user/pass such as opennms, password, admin, blank, etc. but nothing ever allows me in. Is this a problem specifically with OpenNMS or did I miss something? I installed via the ebuild and then finished by reading the book.html in the docs section (where I found the user/pass of admin/admin).

FYI I have never used Tomcat5, Postgres or OpenNMS and these were all fresh installs of each (regular x86 hardware). I ran all of the initializing scripts that I was prompted for and everything seems to be working otherwise. I can for example get to the Tomcat Admin and Tomcat Manager pages.

Anyone have any ideas at all? Should I go contact the OpenNMS community?

hi,
IIRC there is a file in /opt/opennms/etc with the login informations. you have to edit the file to set your admin password

I tried to do the same thing by putting "file:///opt/OpenNMS/webapps/opennms.xml" into the "XML Configuration file URL" box and "/opennms" in the "WAR or Directory URL" box.

I get the following error when I do so:

Code: Select all

FAIL - Encountered exception java.io.IOException: java.lang.ClassNotFoundException: org.opennms.web.log.Log4JLogger

I do have dev-java/log4j-1.2.9 successfully installed.

Any thoughts?

I must say that I have gotten a lot farther along on the opennms install process than I had the last time I posted.

I now have opennms installed and running. I cannot, however, login to the WebUI to do anything with it. I have tried to use the admin/admin user/pass and it just does not work.

On the flip side, I have tried using the /opt/OpenNMS/bin/send-event.pl and was able to tell opennms that there were some nodes to discover and have queried the postgresql tables directly and see that it is actually polling them and discovering nodes and services. So, I know that opennms is running and doing its thing.

But, without the WebUI, I cannot really do anything useful with it.

Any tips on what needs to be done to get the WebUI up and running would be great. Anyone have any experience with this that hangs out somewhere in IRC that would be willing to help me with this?

Well, seems I have finally looked at this thing from the right angle and found the solution to my problem.

in /opt/tomcat5/logs/catalina.out there were entries showing Permission Denied as shown here:

Code: Select all

INFO: Removing web application at context path /opennms
INFO: Processing Context configuration file URL file:/etc/tomcat5/Catalina/localhost/opennms.xml
log4j:WARN No appenders could be found for logger (OpenNMS.WEB.AUTH).
log4j:ERROR Could not read configuration file [/opt/OpenNMS//etc/log4j.properties].
java.io.FileNotFoundException: /opt/OpenNMS/etc/log4j.properties (Permission denied)
        at org.opennms.web.ServletInitializer.init(ServletInitializer.java:139)
        at org.opennms.web.InitializerServletContextListener.contextInitialized(InitializerServletContextListener.java:75)
log4j:ERROR Ignoring configuration file [/opt/OpenNMS//etc/log4j.properties].
log4j:ERROR Could not read configuration file [/opt/OpenNMS//etc/log4j.properties].
java.io.FileNotFoundException: /opt/OpenNMS/etc/log4j.properties (Permission denied)
        at org.opennms.web.ServletInitializer.init(ServletInitializer.java:139)
        at org.opennms.web.InitializerServletContextListener.contextInitialized(InitializerServletContextListener.java:75)
log4j:ERROR Ignoring configuration file [/opt/OpenNMS//etc/log4j.properties].

So, I added the tomcat user to the opennms group and it now starts up without those errors (though I have new ones now) and I can login to the WebUI.
