Not able to start SOLR service - solr

I have installed the solr service on a LINUX environment. Now trying to start the service using the below command
service solr start
After executing this command, am getting below error from the server
Waiting to see Solr listening on port 8080 [-] Still not seeing Solr listening on 8080 after 30 seconds!
tail: cannot open `/var/solr/logs/solr.log' for reading: No such file or directory
I created the solr.log file manually and placed it under the above mentioned path, But as soon, i issue the command "service solr start" . The solr.log file will be renamed and there won't be any new file created with the solr.log. hence the service fails to start. Could anyone let me know how to tackle this issue.
Thanks in advance.

I had a similar issue, and was able to find a hint in the /var/solr/logs/solr-8983-console.log
Originally I had been using Java 8, and Solr was working just fine for me.
When I switched to Java 11, Solr would have the issue you reported.
The log file contained the following:
Java HotSpot(TM) 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.
Unrecognized VM option 'UseParNewGC'
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
I switched back to Java 8 and Solr started just fine.

First, did you use the procedure provided to install the Solr service page 461
Second, did you set the proper overrides to the environment defaults in a solr.in.sh script (p. 462 of the ref manual). You also need to make sure that the LOG4J_PROPS in the solr.in.sh file points to your log4j.properties file. Also make sure that SOLR_LOGS_DIR is pointing to the correct place.
If all that is correct, then check that the values in your log4j.properties file are set correctly (p. 468 of the ref manual).
You can get the reference manual here: https://www.apache.org/dyn/closer.lua/lucene/solr/ref-guide/ if you don't have it already.
I had a tough time getting Solr to run as a service, but in the end I simply wasn't reading carefully enough.

Error creating core in Solr- Solr fail to start

I encountered a problem that I could not figure out for the past week.
After installing another java JDK (Eclipse JDK) and changing the JAVA_HOME value in the computer environment, my Solr service failed to start.
I tried everything, including format to my PC, and new installation as we do every time on a new PC, and I still encounter the same problem.
This is the command the system runs to start the Solr service:
Starting java -Xms3000m -Xmx3000m -verbose:gc -XX:NewRatio=3 -XX:SurvivorRatio=4 -XX:TargetSurvivorRatio=90 -XX:MaxTenuringThreshold=8 -XX:ConcGCThreads=4 -XX:ParallelGCThreads=4 -XX:+CMSScavengeBeforeRemark -XX:PretenureSizeThreshold=64m -XX:+UseCMSInitiatingOccupancyOnly -XX:CMSInitiatingOccupancyFraction=50 -XX:CMSMaxAbortablePrecleanTime=6000 -XX:+CMSParallelRemarkEnabled -XX:+ParallelRefProcEnabled -XX:-OmitStackTraceInFastThrow -DSTOP.PORT=7984 -DSTOP.KEY=mysecret "-Dsolr.install.dir=C:\Program Files\Morphisec Server Dev\solr-6.3.0-ssl\server.." -Djetty.host=0.0.0.0 -Djetty.port=8984 -Dsolr.jetty.https.port=8984 "-Djetty.home=C:\Program Files\Morphisec Server Dev\solr-6.3.0-ssl\server\solr" -Dsolr.autoSoftCommit.maxTime=10 "-Dsolr.log.dir=C:\Program Files\Morphisec Server Dev\solr-6.3.0-ssl\server\logs" -Dsolr.autoCommit.maxTime=60000 -Dsolr.ssl.checkPeerName=false "-Djavax.net.ssl.trustStore=C:\Program Files\Morphisec Server Dev\solr-6.3.0-ssl\server\etc\keystore.solr.jks" -Djavax.net.ssl.trustStorePassword=DEA7B39145F6478C -DzkClientTimeout=15000 -DzkRun -jar start.jar --module=https -DurlScheme=https
All the schemas in the folders of Solr do not contain any use of intPointField as mentioned, only TrieField…
We use Solr 6.3.0.
When I enter the Solr UI, into CloudàTreeà the /configs and choose one of my collections, I have a managed-schema file that does not appear in the directory on my PC, and there is a use of intPointField:
I don’t know where it gets it from. (As I mentioned, I even formatted the PC)
This is the log I get for each collection creation fail:

KNIME Command Line Execution - ClassNotFoundException

I'd like to schedule a KNIME workflow. The workflow does its job very good as long as I start it from the KNIME GUI application. When I execute the same workflow via command line, java complains that com.microsoft.sqlserver.jdbc.SQLServerDriver
could not be found (ClassNotFoundException).
I invoke it via:
"D:\Progamme\KNIME\knime.exe" -nosplash -application -consoleLog org.knime.product.KNIME_BATCH_APPLICATION -preferences="absolutepathto\preferences.epf" -workflowDir="absolutepathto\workflow"
Since the error message signals missing content in the java CLASSPATH I also tried to add the parameters
-vmargs -classpath .;"absolutepathto/sqljdbc42.jar"
But still I earn a java slap, pointing to the same error...
I also tried to run the command from within the knime.exe's directory and I also tried to add the JAR file to Preferences -> Java -> Build Path -> Classpath Variable / User Libraries (referenced via the -preference argument). But that had no effect.
Did anybody face the same problems? Maybe with other third party JARs?
It is all about a Database connector that is configured like this:
Does the integrated security maybe force a misleading error?
System spec: KNIME 3.2.2 on Windows Server 2008 R2
Update - extract from preferences file
/configuration/org.eclipse.core.net/org.eclipse.core.net.hasMigrated=true
/configuration/org.eclipse.ui.ide/MAX_RECENT_WORKSPACES=10
/configuration/org.eclipse.ui.ide/RECENT_WORKSPACES=<list of some workspaces>
/configuration/org.eclipse.ui.ide/RECENT_WORKSPACES_PROTOCOL=3
/configuration/org.eclipse.ui.ide/SHOW_RECENT_WORKSPACES=false
/configuration/org.eclipse.ui.ide/SHOW_WORKSPACE_SELECTION_DIALOG=true
Is there maybe a problem due to the fact that it is a shared KNIME instance among several users and the command line execution does not know which workspace has to be chosen? Is the workspace somehow needed and why?
Partial Solution:
I finally managed it but I don't know exactly why it works now. What I did was to load a fresh portable version of KNIME and ran the same commands only changing the executable path to the new portable version. Before that I started the portable version once to set the workspace directory and register the database driver in preferences dialog and .ini file, nothing else, same configuration so far as the shared KNIME instance. What I am really wondering abpout is that from now on the commands are also working with the shared KNIME instance. I really don't know what caused the change that let KNIME find the driver class.
Info
Because I encountered a few more problems within shared environment in KNIME command line mode, that led to undeterministic execution results, I wrote a little .NET library. This gives me more flexibility/control over the workflow execution (which returncodes and error messages occured and so on). You can find it here if you're interested: KnimeNet
I took a very minimal approach:
cd "C:\Program Files\KNIME"
.\knime -nosplash -noexit -consoleLog -reset -application org.knime.product.KNIME_BATCH_APPLICATION -workflowFile="D:\Work\Knime Workflows\Output\CMD_Test.knwf" -preferences="D:\Work\Knime Workflows\Output\CMD_Test.epf"

How to fix SERVICE_PAUSED error on starting nssm server

So I need to run a custom server. It worked on other machines, but not on mine (all of them are on Windows).
My input:
nssm start custom-server
Error message:
custom-server: Unexpected status SERVICE_PAUSED in response to START control.
I tried to re-start it, but got the same message.
Use the following instructions to change I/O redirects:
nssm set [SERVICE_NAME] AppStdout [APP_PATH_INSTALL]\logs\service.log
nssm set [SERVICE_NAME] AppStderr [APP_PATH_INSTALL]\logs\service-error.log
Check the service log files to find the failure.
In my case, the failure was caused by a dependency on Python libraries.
As Garric15 states it is probably your install command.
This could be for example a StdOut redirect to a path / file that does not exist on your local machine.
Look in the Application event log for errors where the source is nssm around the time you installed the service.
The reason is because firewall is blocking the software which you are running as a service, start first software separately, it will ask you to add to firewall exclusions , then you can use it via nssm
Some scenario
App directory not provided or doesn't exist
nssm nssm set xyz-service AppDirectory "D:\Work\ShoppingKart"
File which is given for service may be corrupted (rebuild code)
The application trying to run is not proper or corrupted. Try to run without windows service once.
Program (.exe) file path not found (in this case look for the solution, or else give full path, if java not found even if it is there in env, just add full path)
I solved it by using no mws (Managed Windows Service?) release,
ex.
gogs_0.12.10_windows_amd64 works
gogs_0.12.10_windows_amd64_mws not working
The issue for me was there had been a Java update on my machine. The JAVA_HOME environment variable was now pointing to an invalid directory (i.e. the old Java version). Just needed to update the JAVA_HOME path and restart the solr services to fix it.
I was attempting to configure rclone as a windows 10 service. I fixed it including the rclone.conf archive inside the rclone folder.
In my case, the problem was that after the service was installed using nssm.exe, the program name was changed. This caused service to always go to paused state after start or restart the service, using either services.msc or nssm.exe command line.
Editing service nssm.exe startup parameters solved the problem for me.

Cakephp giving Fatal error in my local computer

I have a projects in cakephp which is a big size projects.. It is running perfectly in another computer or in the server. But when I copy the files and database to my local computer then it shows the following error.
Fatal error: Maximum function nesting level of '100' reached, aborting! in D:\wamp\www\faceadz\cake\libs\debugger.php on line 248
Project is running in wamp server.
Please help me...
thanks
there might be 2 solution will work for you in you local machine configuration
1. A simple solution solved to your problem. you can just commented the:
"zend_extension = "d:/wamp/bin/php/php5.3.8/zend_ext/php_xdebug-2.1.2-5.3-vc9.dll"
in your php.ini file. This extension was limiting the stack to 100 so I disabled it. The recursive function is now working as anticipated.
2. and
Assuming you're using xdebug, you can set your own limit with
ini_set('xdebug.max_nesting_level', $limit)
EDIT
Also it will help you
changes the file /etc/mysql/my.cnf parameter to something like that max_allowed_packet = 512M
Get sure you've got xdebug installed (use phpinfo()) and then change the file /etc/php5/fpm/php.ini adding or editing the line : xdebug.max_nesting_level=1000
Restart both services sudo service mysql restart sudo service php5-fpm restart
If it doesn't work you can still set those two parameters to false at /etc/php5/fpm/php.ini xdebug.remote_autostart=0 xdebug.remote_enable=0
hope it will help you,

NoClassDefFoundError MimeTypeException with PDF extraction

I am getting an exception trying to use update/extract with PDF files
My Set up is:-
Ubuntu Server 11.10
Tomcat 6
Solr 3.5.0.2011.11.22.15.54.38
I can browse to solr/admin OK
I have put all the contrib/extract and apache-solr-cell3.5.0.jar libraries into the tomcat folder webapps/solr/WEB-INF/lib
I am calling extract using:-
curl "http://localhost:8080/solr/update/extract?uprefix=attr_&fmap.content=attr_content&commit=true" -F "file=/path/to/my.pdf"
error is
java.lang.NoClassDefFoundError: org/apache/tika/mime/MimeTypeException

Would appreciate any pointers - the only time this error seems to come up elsewhere is with Nutch and cached results.
I have tried sending the mimetype in the querystring and also a *.doc file but got the same error.
According to the error message it is not a MimeTypeException exception you get: The problem is a NoClassDefFoundError, because Solr cannot load the class MimeTypeException.
Normally this class is present in tika-core.jar.
Make sure you actually have that file and also check if you have a lib statement in your solrconfig.xml pointing to the right directory.
This was due to the basic error of copying the necessary tika libraries (to tomcat6/webapps/solr/WEB-INF/lib) but leaving ownership of the jar files as ROOT instead of chown-ing them to TOMCAT6. After setting the right permission and restarting Tomcat it started working OK
Found the solution of this problem, I was using SolrJ to update my pdf indexing.
after deploy solr to tomcat, I didn't include the following libraries into the tomcat/webapp
and I get all the lazy loading problem, etc etc
I even try to get apache tika...
until I do this...
shutdown tomcat
\apache-solr-3.5.0\contrib\extraction
copy the libraries above to below
\apache-tomcat-7.0.26\webapps\solr\WEB-INF\lib
startup tomcat
cheers
