Hi, I am Sonali looking to participate in this years Google Summer of Code. I was hoping to contribute to MariaDb. I tried building MariaDb from source using instructions found here https://mariadb.com/kb/en/mariadb/generic-build-instructions/. Configure, make and make install were successful. But I faced problem under section Starting MariaDB for the first time. When I executed the step:
scripts/mysql_install_db --user=mysql
I received an error saying: ...
[Note] InnoDB: The InnoDB memory heap is disabled [Note] InnoDB: Mutexes and rw_locks use GCC atomic builtins [Note] InnoDB: Memory barrier is not used [Note] InnoDB: Compressed tables use zlib 1.2.8 [Note] InnoDB: Using Linux native AIO [Note] InnoDB: Using SSE crc32 instructions [Note] InnoDB: Initializing buffer pool, size = 128.0M [Note] InnoDB: Completed initialization of buffer pool [ERROR] InnoDB: Data file ./ibdata1 is of a different size 768 pages (rounded down to MB) than specified in the .cnf file 64000 pages! [ERROR] InnoDB: Could not open or create the system tablespace. If you tried to add new data files to the system tablespace, and it failed here, you should now edit innodb_data_file_path in my.cnf back to what it was, and remove the new ibdata files InnoDB created in this failed attempt. InnoDB only wrote those files full of zeros, but did not yet use them in any way. But be careful: do not remove old data files which contain your precious data! [ERROR] Plugin 'InnoDB' init function returned error. [ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed. [ERROR] Unknown/unsupported storage engine: InnoDB [ERROR] Aborting
Installation of system tables failed! Examine the logs in ./data for more information. The problem could be conflicting information in an external my.cnf files. You can ignore these by doing:
shell> ./bin/scripts/mysql_install_db --defaults-file=~/.my.cnf
You can also try to start the mysqld daemon with:
shell> ./bin/mysqld --skip-grant --general-log &
and use the command line tool ./bin/mysql to connect to the mysql database and look at the grant tables:
shell> ./bin/mysql -u root mysql mysql> show tables;
So I tried to run mysqld but that didn't work either. I had MySql installed earlier, but I removed it because it was getting very confusing with that. I also tried to run from source as mentioned here https://mariadb.com/kb/en/mariadb/running-mariadb-from-the-source-directory/. But it gives the following error:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (111 "Connection refused")
I made sure that I uncommented lines from my.cnf which had sock information under client and server. Thanks in advance Sonali
