Installing and upgrading help

Starting Solr on Windows

You need to start Solr for it to work.

I used the following guide to make it work as a service: https://www.norconex.com/how-to-run-solr5-as-a-service-on-windows/

You need to setup a core so Solr can start indexing things.

Setupping a Solr Core

You can copy the folder located in your_solr_folder/server/solr/configsets/basic_configs (named conf) in a new folder which will be the name of your core, for example: your_solr_folder/server/solr/moodle_dev

Then, simply restart your Solr service and it should automatically run the new core, which will be detected by your Moodle instance.

You can confirm the core is there by going back in your Solr dashboard, in the Core Admin page.

If you get a core.properties error, try putting a core.properties file within your core folder and put the following code in it:

</lst>=
name=moodle_dev
</requestHandler>=
<str=name\="collection_name">moodle_dev</str>
<requestHandler=name\="/select">
<lst=name\="defaults">

This is what I did to make it work using Solr 6.0.1 and Moodle 3.1

I still can't see the global search icon on the top of the screen, but the blocks are working fine (that's just a problem of mine, not related to your issue).

Upgraded to Moodle 3.1 and no luck on  working it successfully. We are using Unix environment

Hi there,

    I'm currently using Solr on multiple Windows web instances with no problems, but now I'm looking for a way to use it on all of my Moodle sites (more than 500 sites actually).

Following what I red on forums I need to create 1 core per Moodle site, so I'm just wondering the way to create cores entirely from the command line to automize that into a config script.

Does anyone know how I can deploy Solr cores (assuming core folder already exists into "~\solr-6.2.1-1\apache-solr\server\solr") by command line on Windows ?

Thanks in advance.

@all in this thread ...

Installing Solr Search ... Moodle 3.1.x - CentOS 6 stock ... nothing special - below is also attached as a text file for easy copy and paste into terminal.  Just stepped through this on a VB CentOS 6 ... Moodle 3.1 ...

selinux is set to permissive

As root user

yum install java-1.8.0-openjdk.x86_64

yum install curl-devel

yum install libxml2-devel

pear install pecl/solr

chmod 755 /usr/lib64/php/modules/solr.so

nano /etc/php.d/solr.ini
* insert into above file: extension=solr.so

java -version

cd /root

wget http://apache.org/dist/lucene/solr/5.5.4/solr-5.5.4.tgz

tar zxvf solr-5.5.4.tgz

mv solr-5.5.4 /opt/solr/

cd /opt/solr

cp README.txt /var/www/html/solrreadme.txt
* you can now use http://site/solrreadme.txt to read the readme while
still working in the terminal window/scree

php -m |grep solr
* to check if solr is known to PHP - command will show only 'solr'

service httpd restart

* still in /opt/solr/

bin/solr start

bin/solr create -c moodle

* above command looks strange but execute them from /opt/solr/ or they
won't work.

cd /etc/sysconfig

nano iptables

* duplicate the ssh line and on the duplicated line change port 22 to 8983 and the note that the line is for solr rather than ssh

/sbin/service iptables restart

yum install nmap

nmap -P0 -p 8983 [IPaddressofserver]

* nmap should show port 8983 open and not closed or filtered

You should now be able to use browser to go to:
http://IPADDRESS:8983/solr/
and see the admin panel of Solr
The Moodle index should be there.

Now config Moodle's solr search.

Admin menu -> Plugins -> Search -> then both Manage global search
Step through the 'Steps' in order shown.

Eventually everything should show green.

also, should setup a start script for solr so that it starts upon
reboot of server.

Create a startup script in /etc/init.d/ called solr

Contents of /etc/init.d/solr

---- start below -----------
PIDFILE=/var/run/solr.pid
SOLR_HOME=/opt/solr
START_COMMAND="$SOLR_HOME/bin/solr start -p 8983 -noprompt -m 1g"
NAME="Solr"


start() {
  echo  "Starting $NAME"
  if [ -f $PIDFILE ]; then
    echo -n "$PIDFILE exists. $NAME may be running."
  else
    str=`$START_COMMAND`
    pid=`echo $str | grep -o "pid=[0-9]*" | grep -o "[0-9]*"`
    if [ "$pid" == "" ];
    then
      echo "[FATAL ERROR] Failed to extract pid. Exiting!"
      exit 1
    fi
    echo $pid > $PIDFILE
  fi
  return 0
}


case "$1" in
  start)
    start
  ;;
  stop)
    echo "Stopping $NAME .."
    $SOLR_HOME/bin/solr stop
    rm -f $PIDFILE
  ;;
  status)
    $SOLR_HOME/bin/solr status
  ;;
  restart)
    $0 stop
    #sleep 2
    $0 start
  ;;

  *)
    echo "Usage: $0 (start | stop | restart | status)"
    exit 1
    ;;

esac
exit $?

---- end init.d/solr

To set ... after above file is in place and saved.

chmod ugo+x solr (make it executable)

/sbin/chkconfig --add solr

Test the script:

/etc/init.d/solr status

/etc/init.d/solr restart

See for yourself:

ps aux |grep java

Consider installing Webmin to help admin the server.
Webmin is an open source cPanel ... based on Perl
has it's own web server run from default port 10000 but
during installation one could set it up on 8080 or other port.

To see realtime solr logs:

tail -f /opt/solr/server/logs/solr.log
