无法在Rails应用中使用黑子/ solr重新编制索引-错误：solr配置中存在严重错误

Question

Ok, so I have a simple rails application and now i'm trying to implement sunspot for search capabilities. However, after I've generated the config file with rails g sunspot_rails:install and after I've started the server and it has made the solr-dir in my rails app-dir and i run bundle exec rake sunspot:solr:reindex I get the following trace:

cakism@saraswati:~/railscode/calendar$ bundle exec rake sunspot:solr:reindex --trace
** Invoke sunspot:solr:reindex (first_time)
** Invoke sunspot:reindex (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute sunspot:reindex

rake aborted!
RSolr::Error::Http - 500 Internal Server Error
Error: Severe errors in solr configuration.

Check your log files for more detailed information on what may be wrong.

If you want solr to continue after configuration errors, change:

 <abortOnConfigurationError>false</abortOnConfigurationError>

in null

I am specially curious about this:

If you want solr to continue after configuration errors, change:

 <abortOnConfigurationError>false</abortOnConfigurationError>

in null

Why would it say in null? Other posts with the same problem as I have has specified the solr/conf/solrconfig.xml, and also, when I change it to false, nothing else happens.

If I remove the searchable block from my model, I don't get any error (but I suppose that's because it doesn't try to do anything then)

I've run the config file through an XML validator, and it says it's bad start-tag name at 2<-1 5<-2 6<90%. However, even if I remove the lines which then gives a valid XML, restart solr, and try to reindex, I still get the same error.

I'm starting to get desperate here, so any help is greatly appriciated!

Answer 1

I was having a very similar problem and solved it by

• stopping all running solr processes
• removing the solr folder
• turn off/restart the computer
• gem uninstall all related gems
• bundle install
• start solr
• reindex solr

Answer 2

it happened to me occasionally.. in my case it was solr (not sunspot) issue

try to go to

http://localhost:8982/solr/admin

or http://localhost:8983/solr/admin

or http://[your.domain]:8983/solr/admin

(depending on what environment you use)

to see what error you have under solr web server

i saw the java error message and fixed it with just deleting index directory and restarting solr

and it began to behave as expected

hope it helped

Answer 3

or you can re install the gem. This works for me.

Answer 4

Here is the easy way ( does not require messing with gems or restarting computer ):

rake sunspot:solr:stop

If you have modified the schema, copy the contents of site_root/solr/conf/schema.xml to your clipboard

Next, delete the entire solr folder at site_root/solr

Now run:

rake sunspot:solr:start

This command will create and repopulate the deleted solr folder.

If you copied schema.xml above, open schema.xml again, select everything, and copy the contents of your clipboard. Save the file.

Now run:

bundle exec rake sunspot:solr:reindex

Answer 5

More specifically, I found out the cause for my problem, hope this helps any souls who was wondering what happened

First, I deleted the solr/data folder. Bad idea. And this caused the errors as described by cakism.

Restarting, deleting solr folder, etc. won't help. Simply because there is an instance of Solr server running and it will not be stopped even with sunspot:solr:stop. You have to kill that instance by:

rake sunspot:solr:stop # stop server
ps -A | grep solr      # you'll see the [PID] of the solr server
kill [PID]             # replace with the [PID] from above to completely kill the solr instance

After this, you can then proceed with deleting the solr folder and starting the server again

Answer 6

I was facing same issue, and finally I got config/database.yml has wrong database name and, than I checked sunspot.yml, this file has also wrong configuration like ip address. I modify both of file than it start to work.

Answer 7

For me, there was so much dependency with turn off/restart the computer (It was not possible to restart) and does not work any thing from above(I am not trying with restart). So, my working solution was

1. Go to app root directory.
2. using ps aux | grep solr ps aux | grep solr find solr process ID
3. stop solr process using kill -9 4313 # for me 4313 was solr process id

4. start solr on staging rake sunspot:solr:start RAILS_ENV=staging

5. re-index solr using rake sunspot:solr:reindex RAILS_ENV=staging

That's it.

NB: Replace environment according your need
