https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=24845 Bug ID: 24845 Summary: Web-based installer consistently fails while creating database tables. Change sponsored?: --- Product: Koha Version: 19.11 Hardware: All OS: All Status: NEW Severity: major Priority: P5 - low Component: Installation and upgrade (web-based installer) Assignee: koha-bugs@lists.koha-community.org Reporter: dwight.tuinstra@gmail.com QA Contact: testopia@bugs.koha-community.org CC: gmcharlt@gmail.com Created attachment 100504 --> https://bugs.koha-community.org/bugzilla3/attachment.cgi?id=100504&action=edit indexer-output.log, showing table-doesn't exist errors before web installer is run. Installation by following the wiki document "Koha on Debian" fails. I am able to successfully get through the preliminary steps leading up to the web-based installer, and the first handful of screens in that installer. The problem occurs after clicking on the button to create the database tables. After several minutes of no activity, the brower reports "'Gateway Timeout' The gateway did not receive a timely response from the upstream server or application." At this point, table creation in mysql/mariadb stops, after a varying number of tables (around 160 to 180) have been created. There are two possible causes that I've been able to see so far: POSSIBILITY 1: There is an indexer problem that occurs even before the point where the web installer is run. The file /var/log/koha/biblioteca/indexer-output.log begins to fill up with error messages -- see attached files. After this, the log continues to grow with the last two lines constantly added over and over. Curiously, though, this stops about the time that the web installer is run. POSSIBILITY 2: The creation of database tables takes so long that the browser or installer times out, or race conditions arise. I watched table creation in another window as the web installer was running. Table creation seemed to go slow (roughly a table every second) even though there was plenty of free memory, free disk space (with low disk activity), and the CPUs were over 95% idle. Table creation stopped at 162 tables, at almost the exact same moment that the browser gave the timeout message, so I'm not sure if that's all the tables or if there are supposed to be more. What's odd here is that the web installer writes a good number of messages to /var/log/koha/biblioteca/intranet-error.log, each saying that one of these database tables do not exist: language_descriptions, language_subtag_registry, or systempreferences. However, all of these tables *do* exist in the database when one examines it later, which suggests a race condition. This problem is perfectly repeatable -- I've gone so far as to script the manual steps from the wiki documentation to ensure all steps are done, and done as specified. This problem is preventing Koha from being installed and used.
