#cp support-files/my-medium.cnf /etc/my.cnf  （128M Memory ）
perhaps cp support-files/my-large.cnf /etc/my.cnf（512M Memory ）
perhaps cp support-files/my-huge.cnf /etc/my.cnf（1-2G Memory ）

perhaps cp support-files/my-innodb-heavy-4G.cnf /etc/my.cnf（4G Memory ）

** If there is no my-large.cnf Etc. may be caused by version , It doesn't matter. You can use the default my.cnf Then modify it according to the business requirements **

#bin/mysqld_safe --user=mysql &   （ Wait a while and press enter ）
#cp support-files/mysql.server /etc/init.d/mysql
