[root@localhost support-files]# cp my-medium.cnf /etc/my.cnf

my.cnf配置一下數據庫的默認字符集utf8，將如下內容複製到my.cnf便可

[client]
default-character-set=utf8

[mysql]
default-character-set=utf8

[mysqld]
init_connect='SET collation_connection = utf8_unicode_ci'
init_connect='SET NAMES utf8'
character-set-server=utf8
collation-server=utf8_unicode_ci
skip-character-set-client-handshake

註冊和初始化MySQL服務

進入到scripts目錄，執行;

[root@localhost scripts]# ./mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data &
[1] 40869
[root@localhost scripts]# Installing MySQL system tables...

OK

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 localhost.localdomain 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 at http://bugs.mysql.com/


[1]+  Done                    ./mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
[root@localhost scripts]#

啓動mysql和進入mysql

[root@localhost scripts]# /etc/init.d/mysql start
Starting MySQL.Logging to '/usr/local/mysql/data/localhost.localdomain.err'.
. SUCCESS! 
[root@localhost scripts]#

[root@localhost bin]# ./mysql -uroot -p
Enter password:

爲了能全局使用mysql，須要創建一個軟鏈接，也能夠配置profile：

[root@localhost bin]# ln -s /usr/local/mysql/bin/mysql /usr/local/bin/mysql
[root@localhost bin]#

完畢！
