This isstrongly recommended for production servers.See the manual for more instructions.You can start the MySQL daemon with:cd . ; ./bin/mysqld_safe &You can test the MySQL daemon with mysql-test-run.plcd ./mysql-test ; perl mysql-test-run.plPlease report any problems with the ./bin/mysqlbug script!
