To start mysqld at boot time you have to copy

support-files/mysql.server to the right place for your system



PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !

To do so, start the server, then issue the following commands:



/usr/local/mysql/bin/mysqladmin -u root password 'new-password'

/usr/local/mysql/bin/mysqladmin -u root -h rac1 password 'new-password'



Alternatively you can run:

/usr/local/mysql/bin/mysql_secure_installation



which will also give you the option of removing the test

databases and anonymous user created by default.  This is

strongly recommended for production servers.



See the manual for more instructions.



You can start the MySQL daemon with:

cd /usr/local/mysql ; /usr/local/mysql/bin/mysqld_safe &



You can test the MySQL daemon with mysql-test-run.pl

cd /usr/local/mysql/mysql-test ; perl mysql-test-run.pl



Please report any problems with the /usr/local/mysql/scripts/mysqlbug script!

vi /root/.bash_profile

在PATH=$PATH:$HOME/bin后添加:/usr/local/mysql/bin

source /root/.bash_profile
