Logged into Windows Server 2016 as Administrator, I can run Solr from the command line: bin\solr.cmd start -p 8983 -f
I have configured a Solr to run as a Windows Service - running as the same user, with the same command, same startup directory, etc. - however under load, the following error comes back from the upstream application (Sitecore xConnect, though this shouldn't make a difference)
{metadata={error-class=org.apache.solr.common.SolrException,root-error-class=org.apache.solr.common.SolrException},msg=SolrCore is loading,code=503}
To reiterate, everything works fine when Solr is started from the command line, only when it's run as a Windows Service does it error.
Solr version: 6.6.3
Windows version: Server 2016
Environment: AWS (m5.large EC2 instance)
Sitecore compatibility table says to use Solr 6.6.1 with Sitecore, You should still use 6.6.2 as it fixes a bug in Solr 6.6.1 that can affect the installation of SIF. Read here
I recommend you try again with Solr 6.6.2
It turns out that the service was configured to run without the -f flag. So the process would continually stop and re-spawn.

I configure logstash service following the instructions in the link https://www.elastic.co/guide/en/logstash/current/running-logstash-windows.html (logstash as a service using nssm) but I noted that the service does actually not running when I am disconnected from the remote server I installed it.
Is there a way to fix this problem?
thanks,
g
The same thing happens also running logstash manually (I mean , running the appropriate bat file in command prompt).
In Elasticsearch 5.x, changing settings in etc/init.d/elasticsearch does nothing. Where should I change the startup settings (not elaticsearch.yml) when running Elasticsearch 5.x as a service?
Elasticsearch 5 installed through the Debian installer uses Systemd rather than init.d to autostart, so the config file for the service would be in
/usr/lib/systemd/system/elasticsearch.service
Additionally, the settings for the Java Virtual Machine (also started at startup time) are in
/etc/elasticsearch/jvm.options
I am now trying to install ES on windows 2016 Nano server, it works when start ES in command line, but failed to start ES as windows service, maybe due to some changes on Nano server, but I have no hint at all why it didn't work.
Anyone has experience on installing ES on Nano server?
or Where can I get the source code of ES windows service, elasticsearch-windows-x64.exe? It could be helpful to troubleshoot the root cause.
I haven't got a chance to test it on Nano Server 2016, but I've installed ES 5.1.2 + JDK1.8.0_121 on Windows 2016 Server Core successfully and was able to start the service.
Install JDK and set SYSTEM ENV with setx -m JAVA_HOME
"C:\PROGRA~1\Java\jdk1.8.0_121" command. It doesn't work with user level ENV variable such as using set JAVA_HOME=xxx.
unzip ES to c:\elk\elasticsearch
Edit the elasticsearch.yml config file, config the Cluster and Node names and save it
install the ES service C:\elk\elasticsearch\bin>elasticsearch-service.bat install
start the ES service C:\elk\elasticsearch\bin>elasticsearch-service.bat start

I am a newbie on Liferay and furthermore 100% Windows infrastructure knowledge based. I installed Liferay 6.2 on my Windows 2012R2 server together with Java jdk-8u5 version. All is running perfect as long as I am logged in as user on the Server via remotedesktop having open the tomcat startup.bat window.
What have I to do exactly to start Liferay and/or tomcat as service?
Thanks in advance for your efforts.
Configuring liferay or tomcat to run as a service on a windows server doesn't differ that much.So in order to do that you have to add some files to the LIFERAY_HOME\tomcat\bin directory.
To get those files you have to download a full version of 64-bitWindows tomcat from here :
http://tomcat.apache.org/download-70.cgi.
Extract the zip and go to the bin directory, copy service.bat , tomcat7.exe and tomcat7w.exe to this location : LIFERAY_HOME\tomcat\bin
Setting Up the service
Open the commad prompt (Make sure you have admin rights or run the command prompt as administrator),In Command Prompt go to LIFERAY_HOME\tomcat\bin and Execute the following command
service.bat install tomcat7
This will install the tomcat6 service in windows.
Now execute following commond to setup additional configuration for the service
tomcat7w.exe ES tomcat7.exe
2 . Extra configuration :
-XX:MaxPermSize=512m
-Dfile.encoding=UTF8
-Duser.timezone=GMT
-Djava.security.auth.login.config="%CATALINA_HOME%/conf/jaas.config"
-Dorg.apache.catalina.loader.WebappClassLoader.ENABLE_CLEAR_REFERENCES=false
and make sure to provide enough memory for your service by setting the initial memory pool and the maximum one.
Either go with Rafik Beldi's answer (quite an effort, wow) or just go to tomcat's documentation in case you're still missing some information
I had to delete what was in Java Options completely or it wouldn't start: and then I entered:
-XX:MaxPermSize=512m
-Dfile.encoding=UTF8
-Duser.timezone=America/New_York
-Dorg.apache.catalina.loader.WebappClassLoader.ENABLE_CLEAR_REFERENCES=false
-Djava.net.preferIPv4Stack=true
note that where I am: America/New_York allows for both EST and EDT
I have created a neo4j database on my windows machine.
I have transferred the content of the database directory to my linux machine. This is because I have the community edition which does not support the backup functions.
mtt#mttPC:/var/lib/neo4j/data/log$ sudo service neo4j-service start

Any idea? Are the windows and linux neo4js compatible? Thank you.
Edit
I have made a fresh install of neo4j on my ubuntu machine.
Now I finally get some logs:
2014-05-16 20:01:10.958+0000 ERROR [o.n.k.EmbeddedGraphDatabase]: Startup failed: Component 'org.neo4j.kernel.impl.transaction.XaDataSourceManager#25984c63' was successfully initialized, but failed to start.

2014-05-16 20:01:10.958+0000 INFO [o.n.k.EmbeddedGraphDatabase]: Shutdown started
I should be related to this but I am not sure how to proceed. Is the issue related to the fact that when I copied the database, I just stopped neo4j on my windows machine from the neo4j window?
There is no reason why a Neo4j database should not be transferable between operating systems. Can you please provide the output of data/log/console.log? First thought is that you may have permission issues. The files should be read/write for the user the Neo4j process will run as.
