That means that there was no LoadModule line for mod_jk before that 
config line. You originally posted the first config line "LoadModule 
jk_module modules/mod_jk.so" bus either the module was located somewhere 
else, or - more likely - during this attempt here the LoadModule line wa 
sno longer in place.

errno=13 means access error, so the user who runs the httpd server does 
not have rights to create a shared memory file at 
/etc/httpd/logs/jk-runtime-status.11957. Have a look at 
/etc/httpd/logs/, check whether it exists and whether the httpd runtime 
user has full rights on the directory. If you can not get rights there, 
choose another path where you have rights and set it using


JkShmFile "/path/to/my/jk-runtime-status"

jk_map_handle_duplicates::jk_map.c (456): Duplicate key $


That is weired and doesn't match the config you posted. Especially since 
you didn't use either a worker mapping properties file not any JkMount 
directive. So either with the above problems fixed, i would not expect 
you mod_jk to get any requests passed over from httpd to handle them.


Also the config in your workers.properties doesn't look really good. i 
suggest you look at the exaple config you received inside 
tomcat-connectors-1.2.46-src.tar.gz and start form there. But first fix 
the above first two errors.

Rainer

and make install, and everything seems fine

I then edited the httpd.conf file and added

Re: help installing mod_jk on Centos 7 on a Google Cloud server

Hi Chris,

I tried that and got similar error msgs.

I am wondering if something needs to be defined upstream for Apache, Tomcat
or maybe even Java?

Hey Greg,

Thanks for the info. I changed both httpd.conf and workers.properties to
your settings. Got the same error msg when I restarted httpd.

When I checked journalist I get

I wonder if your shared-memory file is corrupt. Try deleting the file
/etc/httpd/logs/jk-runtime-status (or maybe
/etc/httpd/logs/jk-runtime-status*) and restarting.

I've never seen any errors like the ones you are showing above, so
this is just a shot in the dark.

Also, try a complete "stop" and "start" instead of a graceful shutdown.

RE: Connection pool and parallel deployment problem

Are you talking about parallel deployment or connection pools ?

Parallel deployment is in Tomcat since Tomcat 7

I think it is good for your mental health not to use this feature.
You just have to think of it as an experimental function like google
chrome's about://flags.

JMX has subscribe model.
However, Tomcat is no ability to receive notifications.
And most JDBC implementations are not interested in such features.
Both Tomcat and DB vendors are not going to fix it.

It's not a tragedy, it's just a comedy.

Re: help installing mod_jk on Centos 7 on a Google Cloud server

For my centos/mod._jk I use :

/etc/httpd/conf.d/my.conf :

...
JkWorkersFile "/etc/httpd/conf.d/workers.properties"
JkLogFile "/etc/httpd/logs/mod_jk.log"
JkShmFile "/etc/httpd/logs/jk-runtime-status.log"
JkLogLevel info
JkLogStampFormat "[%a %b %d %H:%M:%S %Y]"

JkMount  / worker1
JkMount  /* worker1


workers.properties :
# Define 1 real worker using ajp13
worker.list=worker1
# Set properties for worker1 (ajp13)
worker.worker1.type=ajp13
worker.worker1.host=localhost

Re: help installing mod_jk on Centos 7 on a Google Cloud server

[Lou Wallace]

Hi Everyone,

So still having issues with mod_jk. I have downloaded

wget
http://www.eu.apache.org/dist/tomcat/tomcat-connectors/jk/tomcat-connectors-1.2.46-src.tar.gz
wget
http://www.eu.apache.org/dist/tomcat/tomcat-connectors/jk/tomcat-connectors-1.2.46-src.tar.gz.sha1

and make install, and everything seems fine

I then edited the httpd.conf file and added

LoadModule jk_module modules/mod_jk.so

JkWorkersFile "/etc/httpd/conf/workers.properties"
JkLogFile "/var/log/mod_jk.log"
JkLogLevel  info
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
JkRequestLogFormat "%w %V %T"

then I edited workers.properties and added

worker.list=app1,app2

worker.app1.type=ajp13
worker.app1.host=app1.example.com
worker.app1.port=8201
worker.app1.socket_timeout=10

worker.app2.type=ajp13
worker.app2.host=app2.example.com
worker.app2.port=8201
worker.app1.socket_timeout=10

Then when I restart Apache using systemctl restart httpd I get

Job for httpd.service failed because the control process exited with error
code. See "systemctl status httpd.servic
e" and "journalctl -xe" for details.

So checking mod_jk log I see

[Wed Nov 21 15:54:19 2018] [11957:140478724515968] [warn]
jk_map_handle_duplicates::jk_map.c (456): Duplicate key $

and the httpd log last entries are

I am not sure if the first 3 are connected to mod_jk, I included them for
those who know far more then me (almost everyone I suspect) just in case

And ideas, hints or thoughts?

Thanks!

Tim,

I'm all ready for a back-port of the EncryptInterceptor to Tomcat 8.5
but I'd like to make sure things are working for you before I do it.

Thanks,

Both nodes have the same encryption key, right? The key itself looks
fine. For example, I dropped that key into the unit test file and it
worked as expected.

I've been working on a patch yesterday and today that uses random IVs
instead of re-using them. It really shouldn't change anything about
the config, etc. but both nodes will require the new code to re-test.
I've also expanded the unit tests to cover cipher block modes other
than CBC.

I don't actually have a cluster here for testing, though, so
everything is being done with the unit tests.

I thought I had reproduced your issue (BadPaddingException) except it
turned out that the test itself was wrong and the interceptor code was
correct.

Are you able to build from source? I'm about to commit these changes
to the trunk (9.0.x), which really shouldn't change anything for you,
but it might fix some edge case that you are hitting.

Hi all,

I wanted to let you know about the amazing progress that is being made
on the Tomcat translations at
https://poeditor.com/join/project/NUTIjDWzrl

In the short time since this effort has started the community has
achieved the following:

- French has increased from 18% to 64% coverage
- Simplified Chinese has been added and has already reached 32% coverage
- Korean has been added and has reached 10% coverage
- German has increased from 2% to 7% coverage
- Brazilian Portuguese has been added and has reached 4% coverage
- Spanish has increased from 42% to 44% coverage

as well as a smaller number of additions and corrections to another 6
languages.

A big thank you to everyone who has contributed.

There is still lots to do so if you would like to help out please join
us at:

That is a warning you should be able to fix by unregistering the JDBC
driver in a ServletContextListener.

That is a thread started by the MySQL driver. There should be an API
provided by the MySQL driver that you can call to stop the thread (again
in a ServletContextListener) although I'd expect that to happen
automatically as part of unloading the driver.

If there is no way to stop the thread then that would be a bug in the
MySQL driver.

Re: Connection pool and parallel deployment problem

[HeeGu Lee]

I think it is good for your mental health not to use this feature.
You just have to think of it as an experimental function like google
chrome's about://flags.

JMX has subscribe model.
However, Tomcat is no ability to receive notifications.
And most JDBC implementations are not interested in such features.
Both Tomcat and DB vendors are not going to fix it.

It's not a tragedy, it's just a comedy.

Connection pool and parallel deployment problem

[Gilles SCHLIENGER]

Hi all,

We are using Tomcat 9 and parallel deployment.

I use a connection pool defined in the xml context (myApp##1.xml, myApp##2.xml 
in my exemple)

I have the following problem :
- I have myApp##1.war deployed using a connection pool (configured in 
myApp##1.xml)
- I deploy myApp##2.war (using a connection pool defined in myApp##2.xml)
- when the last session in myApp##1 expires, myApp##1 is automatically 
undeployed (I have undeployOldVersions="true" in server.xml for the Host) but 
the connections opened by myApp##1 are not closed.

I used the Tomcat configuration from the example in :
https://tomcat.apache.org/tomcat-9.0-doc/jndi-datasource-examples-howto.html#Database_Connection_Pool_(DBCP_2)_Configurations



During undeploy, I get the following messages :

21-Nov-2018 11:42:54.795 AVERTISSEMENT 
[ContainerBackgroundProcessor[StandardEngine[Catalina]]] 
org.apache.catalina.loader.WebappClassLoaderBase.clearReferencesJdbc The web 
application [myApp##1] registered the JDBC driver [org.postgresql.Driver] but 
failed to unregister it when the web application was stopped. To prevent a 
memory leak, the JDBC Driver has been forcibly unregistered.

...

21-Nov-2018 11:42:54.800 AVERTISSEMENT 
[ContainerBackgroundProcessor[StandardEngine[Catalina]]] 
org.apache.catalina.loader.WebappClassLoaderBase.clearReferencesThreads The web 
application [myApp##1] appears to have started a thread named [Abandoned 
connection cleanup thread] but has failed to stop it. This is very likely to 
create a memory leak. Stack trace of thread:
java.base@10.0.1/java.lang.Object.wait(Native Method)
java.base@10.0.1/java.lang.ref.ReferenceQueue.remove(ReferenceQueue.java:151)

java.base@10.0.1/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1135)
java.base@10.0.1/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:635)
java.base@10.0.1/java.lang.Thread.run(Thread.java:844)

I have tested adding < destroy-method=close > but it did not change anything

Is this a bug ?

Thanks for any help !

Translations update

[Mark Thomas]

Hi all,

I wanted to let you know about the amazing progress that is being made
on the Tomcat translations at
https://poeditor.com/join/project/NUTIjDWzrl

In the short time since this effort has started the community has
achieved the following:

- French has increased from 18% to 64% coverage
- Simplified Chinese has been added and has already reached 32% coverage
- Korean has been added and has reached 10% coverage
- German has increased from 2% to 7% coverage
- Brazilian Portuguese has been added and has reached 4% coverage
- Spanish has increased from 42% to 44% coverage

as well as a smaller number of additions and corrections to another 6
languages.

A big thank you to everyone who has contributed.

There is still lots to do so if you would like to help out please join
us at:
