Generated init.d script doesn't work for me

[sauliusgrigaitis]

I wanted to try your trinidad_init_scripts, it generated pretty nice init.d script http://pastiebin.com/?page=p&id=4f0c613b84f7e , but it throws error:

sudo /etc/init.d/trinidad start

Starting daemon...
Cannot find any VM in Java Home /usr/lib/jvm/java-6-sun-1.6.0.26/jre
Unable to redirect to /vol/apps/tsung_city/shared/logs/trinidad.log
Cannot find any VM in Java Home /usr/lib/jvm/java-6-sun-1.6.0.26/jre
Cannot locate JVM library file
Service exit with a return value of 1
Daemon exited with status: 1. Check pidfile and log

Thought my Java really lives at /usr/lib/jvm/java-6-sun-1.6.0.26

Thanks,

How did you install your JVM? What OS are you running?

Also, does the user you are running the service as have permission to the /usr/lib/jvm/java-6-sun-1.6.0.26 directory?

Can you run 'which java' and 'java -version'?

thanks.

Hi jkutner,

I installed JVM using ubuntu packages. I'ts Ubuntu 10.04.

$ uname -a
Linux box2 2.6.32-37-generic #81-Ubuntu SMP Fri Dec 2 20:32:42 UTC 2011 x86_64 GNU/Linux

I tried to run it with sudo and without sudo. That unprivileged user also have read acess to /usr/lib/jvm/java-6-sun-1.6.0.26

$ which java
/usr/bin/java

$ java -version
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode)

BTW, init script generates such START_COMMAND:

I'm not that familiar with the sun-java6 distribution. Can you try using the openjdk-6-jdk package? That is:

sudo apt-get openjdk-6-jdk

Which would give you a java_home of /usr/lib/jvm/java-6-openjdk/jre

I'm seeing a similar problem on a CentOS 6.2 system using openjdk.

sun-java6-jdk is just fine - I'm using it with JAVA_HOME=/usr/lib/jvm/java-6-sun/jre on Debian

the error is really weird, but since I have seen jsvc doing some weirdness already I would suggest compiling/installing jsvc yourself http://commons.apache.org/daemon/download_daemon.cgi (not relying on the one provided) then change the path in your init.d script e.g. JSVC=/usr/local/bin/jsvc

download the commons-daemon-1.0.8-native-src package and compile the binary
or sudo apt-get install jsvc hopefully there's a recent version for Ubuntu 10.04 ...

[kares]

@calavera could we have a wiki here for information such as self compiling/installing jsvc/commons-daemon ?
or is it just fine to put these on trinidad's wiki anyway ?

[ghost]

If it would help whoever is working on this issue, I have a CentOS VirtualBox VM that is having this problem that I could upload somewhere so the problem can be easily reproduced.

[calavera]

@kares, yes, I've enabled the wiki, so we can add that information. It would be good to have it referenced on trinidad's wiki anyways.

@mhuffnagle that would be perfect, any help is always really appreciated.

[kares]

@mhuffnagle so installing JSVC did not help https://github.com/trinidad/trinidad_init_services/wiki/Installing-JSVC ?

[ghost]

@calavera I'll try to get that pulled together for you tonight and I'll PM instructions on where to download it.

@kares I haven't had a chance to install JSVC to see if that works around the problem, I probably won't get a chance to do that for a day or two.

[kares]

confirming that self installing JSVC as I posted previously would solve this issue !

the bundled jsvc_linux binary is a 32-bit one, both reported systems are x64 and use a 64-bit java.
thus the binary fails with that it can not find any (compatible 32-bit) VM in the given Java Home ...

[kares]

1.1.4 is out - we no longer bundle the linux binary instead we package JSVC's sources and try to compile the binary for you (unless installed)
