[root@dbking mysql]# tar -zxvf mysql.tar.gz

[root@dbking mysql]# mv /rpm/mysql /usr/local/mysql

初始化：

[root@dbking mysql]# ./scripts/mysql_install_db --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/ --user=mysql

[root@dbking mysql]# cp /usr/local/mysql/support-files/mysql.server /etc/rc.d/init.d/mysqld

[root@dbking mysql]# chown -R root:root /etc/rc.d/init.d/mysqld

[root@dbking mysql]# chmod 755 /etc/rc.d/init.d/mysqld
