mysql创建多个实例，其实就是把DATA文件，SOCK,PORT指向不同的文件和端口

mysql安装过程看

http://blog.csdn.net/tangpengtao/article/details/6650424

先创建3307的DATA目录

\[root@localhost mysql-5.5.15\]\# mkdir -p

/usr/local/mysql3307

\[root@localhost mysql-5.5.15\]\#

\[root@localhost mysql-5.5.15\]\# chmod +w /usr/local/mysql3307

\[root@localhost mysql-5.5.15\]\# chown -R mysql:mysql

/usr/local/mysql3307

\[root@localhost mysql-5.5.15\]\#

\[root@localhost mysql-5.5.15\]\# mkdir -p /var/mysql3307/

mkdir -p /var/mysql3307/data/

mkdir -p /var/mysql3307/log/

chown -R mysql:mysql /var/mysql3307/

\[root@localhost mysql-5.5.15\]\# mkdir -p /var/mysql3307/data/

\[root@localhost mysql-5.5.15\]\# mkdir -p /var/mysql3307/log/

\[root@localhost mysql-5.5.15\]\# chown -R mysql:mysql

/var/mysql3307/

mkdir -p /usr/local/mysql3307

chmod +w /usr/local/mysql3307

chown -R mysql:mysql /usr/local/mysql3307

mkdir -p /var/mysql3307/

mkdir -p /var/mysql3307/data/

mkdir -p /var/mysql3307/log/

chown -R mysql:mysql /var/mysql3307/

\[root@localhost mysql-5.5.15\]\# cmake
