[root@localhost lib]# cp mysql/* mysql_3307/
cp: omitting directory `mysql/mysql'
cp: cannot open `mysql/mysql.sock' for reading: No such device or address
cp: omitting directory `mysql/test'
[root@localhost lib]# /etc/init.d/mysqld stop
Stopping mysqld: [ OK ]
[root@localhost lib]# cp mysql/* mysql_3307/

[root@localhost Desktop]# mysql_install_db --datadir=/var/lib/mysql_3307 --user=mysql

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/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h localhost.localdomain password 'new-password'
Alternatively you can run:
/usr/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 ; /usr/bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd /usr/mysql-test ; perl mysql-test-run.pl
Please report any problems with the /usr/bin/mysqlbug script!
