./scripts/mysql_install_db
chown -R mysql /usr/local/mysql
chgrp -R mysql /usr/local/mysql
6.启动mysql
/usr/local/mysql/bin/mysqld_safe &

ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock

8.系统自动启动的mysql
cp support-files/mysql.server /etc/init.d/mysql
chmod +x /etc/init.d/mysql
chkconfig –add mysql

create table student (id int(10) auto_increment primary key,
name varchar(100),
note varchar(100)

show tables;
insert into student (name,note) values(‘测试007’,’测试说明’);
