Mediawiki cannot bind to MySql/MariaDB
Last modified: 2017-11-28 17:21:49 EST
Description of problem: On downstream versions of the MediaWiki APB, the deployed mediawiki instance cannot bind to MySql or MariaDB. After binding the resulting page displays an error that "no viable database extension found for type 'mysql'". It seems the downstream APB is missing some PHP packages to use mysql type databases. (Postgres works as expected, however) How reproducible: 100% Steps to Reproduce: 1. Provision MariaDB/MySql APB 2. Provision Mediawiki APB 3. Create binding for the DB 4. Add the secret to the mediawiki application 5. Visit the mediawiki app route Actual results: Mediawiki is shown and usable with no errors Expected results: Error shown "no viable database extension found for type 'mysql'" Additional info: Mediawiki log: Setting up database [ce501b5d] [no req] Exception from line 851 of /usr/share/mediawiki123/includes/db/Database.php: DatabaseBase::factory no viable database extension found for type 'mysql' Backtrace: #0 /usr/share/mediawiki123/includes/installer/MysqlInstaller.php(167): DatabaseBase::factory(string, array) #1 /usr/share/mediawiki123/includes/installer/DatabaseInstaller.php(154): MysqlInstaller->openConnection() #2 /usr/share/mediawiki123/includes/installer/MysqlInstaller.php(485): DatabaseInstaller->getConnection() #3 [internal function]: MysqlInstaller->setupDatabase(MysqlInstaller) #4 /usr/share/mediawiki123/includes/installer/Installer.php(1543): call_user_func(array, MysqlInstaller) #5 /usr/share/mediawiki123/includes/installer/CliInstaller.php(126): Installer->performInstallation(array, array) #6 /usr/share/mediawiki123/maintenance/install.php(118): CliInstaller->execute() #7 /usr/share/mediawiki123/maintenance/doMaintenance.php(105): CommandLineInstaller->execute() #8 /usr/share/mediawiki123/maintenance/install.php(132): require_once(string) #9 {main} AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 172.18.0.14. Set the 'ServerName'
We appear to be missing several optional php packages, including php-mysql, downstream. Working on updating the image.
To clarify upstream canary versions of Mediawiki are not affected by this bug.
mediawiki-123:v3.7.0-0.198.1.1 will work with the mysql apb now. We found a separate issue in mariadb when a random password is generated that will necessitate rebuilding the mariadb APB role and container.
https://github.com/ansibleplaybookbundle/rhscl-mariadb-apb/pull/12
the latest mariadb-apb container will fix the second issue.
In fact, I'm not sure my problem have same root cause with this bug. That because only said while binding to MySql/MariaDB in original description, but all three DB failed in my testing. Please help to confirm and review if it is a block issue for ocp3.7 GA.
The only images that are likely to fully work right now are 3.7.4-2 and 3.7.5-2 when I get them built shortly. Since the puddles started incrementing versions from 3.7.0 we've been getting containers with very old images. We're trying to find out from someone what's going on.
Jason, That is OKay for me. Thanks your explanation.
