groupadd mysql
useradd -g mysql mysql
cd /usr/local/mysql
chown -R mysql .
chgrp -R mysql .
chown -R root .
chown -R mysql data
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
cp /usr/local/mysql/support-files/my-huge.cnf /etc/my.cnf
2.修改my.cnf
nano /etc/my.cnf

datadir=/home/mysql

mysql>UPDATE user SET password=PASSWORD(‘root’) WHERE user=’root’;
mysql>FLUSH PRIVILEGES;
mysql>exit
5.设置自动启动
apt-get install chkconfig
chkconfig –add mysqld
chkconfig mysqld on
6.将mysql加入到path
nano /etc/profile
umask前加进这句
export PATH=$PATH:/usr/local/mysql/bin
