[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!

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;
