I'm trying to set up a solr cloud instance on ubuntu and am having this issue (5 years later, under solr 9): solr installation, cannot start examples
The suggested solution (chown solr.solr...) does not work for me, nor can I run solr as root.
As a last resort, I tried forcing solr start as root: bin/solr start -e cloud -force
but it still errors with permissions:
ERROR: Logs directory /opt/solr/example/cloud/node1/solr/../logs could not be created.
Anyone have a solution to this under solr 9?

I'm currently setting up a Kaltura streaming server on CentOS 7 with mariaDB. When I come to the point the installation manual requires me to install oflaDemo via browser, I only get an empty list. No connection errors occour. The debug output states:
Host: vstream-dev.my.domain
Trying to connect
Net status: NetConnection.Connect.Success
Got the application list
Got the application list
Got the application list
So, in theory there shouldn't be a problem.
Firewall is down for testing/devel
SELinux is off (permissive)
The only error that ocoured during the installation process was packet mysql-server is not installed. But the manual states that I should use mariaDB on CentOS 7.
I tried to clone https://github.com/Red5/red5-examples and link the ofla Demo folder to /usr/lib/red5/webapps/ with no success.
Ok, I solved it.
What I did:
I cloned the repo with the red5 examples: https://github.com/Red5/red5-examples and navigated into the subfolder oflaDemo (with pom.xml).
Then I had to install maven with
yum install -y maven
and do a maven build
mvn clean install
After that, I was able to grab the file target/red5-example-oflaDemo-2.0.war. I extracted this file into a folder oflaDemo in /var/lib/red5/webapps and restarted the server. Finally, I did mkdir /usr/lib/red5/webapps/oflaDemo/streams to create a folder for the streams.
After that, I was able to navigate to the demo via
http://my.domain:5080/oflaDemo/
I am not able to find the indexed data of the files during search
Below are the steps I am following
OS: Windows 7
Solr version: solr 5.2.1
Steps:
cd ..\solr 5.2.1\bin
solr start -e techproducts
Check if solr is up and running and core is visible. Search for the indexed files. Total 32 files exists and shown in the search result .
cd ..\solr-5.2.1\example\exampledocs
curl "http://localhost:8983/solr/techproducts/update/extract?literal.id=33&commit=true" -H "myfile=#example/exampledocs/test.pdf"
Result: It shows successfully indexed and committed but the files returned from the search are still 32 files.
try with other way of indexing ... java -Durl=http://localhost:8983/solr/techproducts/update/extract -Dparams=literal.id=33 -jar post.jar test.pdf It indexed and committed successfully
Open solr GUI and do a search now 33 files returned , but can not see any information of the test.pdf file, meta data and data both not visible
Restart the solr
now we can see the data of the file
Surprisingly instant commit worked for me just a day before with the same configuration, once I did delete all index, from then I am facing this problem not only with this solr instance for other solr instances in the same machine.
Below are the autocommit config from solrconfig.xml
<autoCommit>
<maxTime>${solr.autoCommit.maxTime:15000}</maxTime>
<openSearcher>false</openSearcher>
</autoCommit>
<autoSoftCommit>
<maxTime>${solr.autoSoftCommit.maxTime:-1}</maxTime>
</autoSoftCommit>
My goal is to demonstrate creating a local debian repository with controlled versions of tools used (e.g. compiler versions) to make a build system more predictable.
I've tried to follow this example: http://linuxconfig.org/easy-way-to-create-a-debian-package-and-local-package-repository
but when I get to the apt-get update stage, I always get a 404 not found on the repository I've added.
The apache2 server is running, I can view the default page installed at http://localhost/html/index.html.
I am trying this with the file fortune-mod_1%3a1.99.1-7_amd64.deb installed to /var/www/debs. I create the Packages.gz file as the tutorial suggests:
dpkg-scanpackages debs /dev/null | gzip -9c > debs/Packages.gz
I also add a new file: /etc/apt/sources.list.d/myppa.list with this line:
deb http://localhost debs/
I restart the apache2 service just in case:
sudo service apache2 restart
but running:
sudo apt-get update
still produces this error:
W: Failed to fetch http://localhost/debs/Packages 404 Not Found
Is there something basic I'm missing? Ultimately, I'd like to get this working over a LAN, but first have to get it working on a single machine.
EDIT: I'm doing this on Ubuntu 14.04.
EDIT: Show contents of file /etc/apt/sources.list.d/myppa.list
tldr; use aptly
It's the easiest apt repository management tool I've found and it comes with neat tutorial showing how to create, populate, and publish your own apt repository.

I ended up solving the problem. It was an issue with the default document root being different for the tutorial than on my system. All I did was move my debs folder to html (document root turns out to be /var/www/html, not just /var/www on my install). That did the trick.
I want to stop Solr server which is been started with below command
$ solr start -e dih
by above command my intention was to launch example DIH application bundled with the package.
Now I want to stop the above server, when I try to stop, I am getting below error:
$ solr stop -p 8984
ERROR: Solr home directory D:\Softwares\solr-5.0.0\ must contain
solr.xml
I am new to Solr.
i had set the SOLR_HOME as solr\bin, but where as per the document , it says
The Solr Home directory typically contains the following...
solr.xml *
so i have set SOLR_HOME to solr\server\solr, where i have solr.xml.
after modifying my home to above path, solr stop starts working

Postgresql failed to start
This problem has been driving me crazy and nothing seems to be working. I need to change the location where postgresql stores the data base. I am a complete novice when it comes to using commands in the terminal and step by step instructions with the proper commands would really help. I searched all over the web but all instructions assume some prior good knowledge to terminal commands. I did try one approach by creating a symbolic link in the main data folder to my required location. This gives me an error that asks me to check the log file. However, I have no idea where the log file is. A lot of people seem to have this problem and a step by step solution would surely help. My Psql version is 8.4. Ubuntu 10.10
The latest log file full path is /var/log/postgresql/postgresql-8.4-main.log but the symbolic link is not the more integrated/easy way to change the data location.
I'd suggest to do it by creating the entire cluster to the desired location, with the pg_createcluster command that comes with the debian/ubuntu postgres packages.
1- delete your current cluster, if it does not contain any prior data:
$ sudo pg_dropcluster --stop 8.4 main
2- create a new cluster at the new location
$ sudo pg_createcluster -d /path/to/new/location 8.4 main
3- restart postgresql
$ sudo /etc/init.d/postgresql start
