ILIAS-7-Install-Tutorial for Ubuntu 20.04

Troubleshooting

Check the Logfile

I am sorry for the poor formating of the text, but I have difficulties with this new version of the ILIAS page editor.

Check the ILIAS-Database Information

  • Normally the connection settings that ILIAS uses to find the running RPC-Server are given through the JSON-File
  • Since ILIAS 7, there is no menu entry in the administration-section of the ILIAS instance
  • That means, in case of error we should look to the database directly:
    • Install PHPMyAdmin as described here at the end
    • Open the table settings
    • In table settings, look for the columns
      • rpc_server_host
      • rpc_server_port

Check the database

  • Check if the host and port are the same as in the config-file

Use only manual Indexing

  • I do not prefere the indexing via cronjob. In all my installations I use manual indexing

Error calling curl_exec()

  • The ILIAS logfile in /opt/iliasdata/log/ilias.log
  • gives the following RPC related error:
  • ilias_wsrv.ERROR: ilRpcClient::__call:573 RpcClient could not connect to http://:0//RPC2 Reason 0: Error calling curl_exec().

Other suggestions:

  • After choosing "Lucene search" in ILIAS->Administration->Search, the message Error calling curl_exec(). appears
    • Check if the server is running: pgrep -af "lucene"
    • If this gives nothing, the server is not running. Try start again.
  • Try manually indexing Start manually indexing
  • Bevor you start, upload a file. Example: https://github.com/mxw/grmr/blob/master/src/finaltests/bible.txt
  • Start the indexing process. The size of your folder in /opt/iliasdata/lucene should increase accordingly:
  • du -h /opt/iliasdata/lucene
  • Try again and delete the current search index. Example: rm -r /opt/iliasdata/lucene/ilias_14255
