Deploying Moodle on Azure – things you should know
Moodle is one of the most popular open-source learning management platform empowering educators and researchers across the world to disseminate their work efficiently. It is also one of the most mature and robust OSS applications that the community has developed and improvised over the years. We have seen customers from small, medium, and large enterprises to schools, public sector, and government organizations deploying Moodle in Azure. In this blog post, I’ll share some best practices and tips for deploying Moodle on Azure based on our experiences working with several of our customers.Tips and Tricks in using mysqldump and mysql restore to Azure Database for MySQL
While importing data into Azure Database for MySQL, errors may occur. This blog will walk through common issues that you may face and how to resolve it. Access denied; you need (at least one of) the SUPER privilege(s) for this operation: Error ERROR 1227 (42000) at line 101: Access denied; you need (at least one of) the SUPER privilege(s) for this operation Operation failed with exitcode 1 Issue Importing a dump file that contains definers will result in the above error. As all of us know, only super users can perform and create definers in other schemas. Azure Database for MySQL is a managed PaaS solution and SUPER privileges is restricted. Solution Either replace the definers with the name of the admin user that is running the import process or remove it. The admin user can grant privileges to create or execute procedures by running GRANT command as in the following examples: GRANT CREATE ROUTINE ON mydb.* TO 'someuser'@'somehost'; GRANT EXECUTE ON PROCEDURE mydb.myproc TO 'someuser'@'somehost'; Example: Before: DELIMITER ;; /*!50003 CREATE*/ /*!50017 DEFINER=`root`@`127.0.0.1`*/ /*!50003 …… DELIMITER ; After: DELIMITER ;; /*!50003 CREATE*/ /*!50017 DEFINER=`AdminUserName`@`ServerName`*/ /*!50003 …… DELIMITER ; importing triggers while binary logging is enabled: Error ERROR 1419 (HY000) at line 101: You do not have the SUPER privilege and binary logging is enabled (you *might* want to use the less safe log_bin_trust_function_creators variable) Operation failed with exitcode 1 Issue Importing a dump file that contains triggers will result in the above error if binary logging is enabled. Solution To mitigate the issue, you need to enable the parameter “log_bin_trust_function_creators” from Azure portal parameters blade. storage engine not supported: Error ERROR 1030 (HY000) at line 114: Got error 1 from storage engine Operation failed with exitcode 1 Issue You will see the above error when you use a storage engine other than InnoDB and MEMORY. Read more on support engine types here: Storage engine support Solution Before the import process make sure that you are using a supported engine type; InnoDB and MEMORY are the only supported engine types in Azure Database for MySQL. If you dumped the data from a different engine type, edit the file and replace the storage engine. For example, exchange ENGINE=MYISAM with ENGINE=InnoDB. Note: You can always dump the schema first using the command: mysqldump --no-data option, and then dump the data using option: mysqldump --no-create-info option Example : Before: CREATE TABLE `MyTable` ( `ID` bigint(20) NOT NULL AUTO_INCREMENT, `DeviceID` varchar(50) NOT NULL, PRIMARY KEY (`ID`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8; After: CREATE TABLE `MyTable` ( `ID` bigint(20) NOT NULL AUTO_INCREMENT, `DeviceID` varchar(50) NOT NULL, PRIMARY KEY (`ID`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; InnoDB storage engine row format: Error ERROR 1031 (HY000) at line 114: Table storage engine for 'mytable' doesn't have this option Operation failed with exitcode 1 Issue In Azure Database for MySQL, four row format options are supported: DYNAMIC, COMPACT and REDUNDANT, the COMPRESSED row format is supported under certain conditions. Solution We support compressed format on General Purpose or Memory Optimized. Customer needs to enable the parameter “innodb_file_per_table” from Azure portal parameters blade, and key_block_size must be 8 or greater than 8. In default, key_block_size is 8.
