1、按照常规安装。
[root@ff_girl mysql5122]# chown -R root .
[root@ff_girl mysql5122]# chown -R mysql data
[root@ff_girl mysql5122]# chgrp -R mysql .
[root@ff_girl mysql5122]# cp support-files/my-small.cnf /etc/my5122.cnf
[root@ff_girl mysql5122]# scripts/mysql_install_db --basedir=/usr/local/mysql5122/ --datadir=/usr/local/mysql5122/data/ --user=mysql
Installing MySQL system tables...
OK
Filling help tables...
OK
To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
。。。
首次启动MYSQL
[root@ff_girl mysql5122]# bin/mysqld_safe --defaults-file=/etc/my5122.cnf &
[1] 13700
[root@ff_girl mysql5122]# 080124 15:01:46 mysqld_safe Logging to '/usr/local/mysql5122/data/localhost.localdomain.err'.

[root@ff_girl mysql5122]# bin/mysql -uroot -p -S/tmp/mysql5122.sock
Enter password:

停掉MYSQL服务。
[root@ff_girl ~]# /usr/local/mysql5122/bin/mysqladmin -uroot -p -S/tmp/mysql5122.sock shutdown
Enter password:
[root@ff_girl ~]#
拷贝元数据。
[root@ff_girl mysql5122]# cp data data2
[root@ff_girl mysql5122]# mv data data1
[root@ff_girl mysql5122]# chown -R mysql data2
[root@ff_girl mysql5122]# chgrp -R mysql .

[root@ff_girl mysql5122]#
启动两个MYSQL服务
[root@ff_girl mysql5122]# /usr/local/mysql5122/bin/mysqld_multi --config-file=/etc/my5122.cnf start 1-2
[root@ff_girl mysql5122]# netstat -an | grep 3307

[root@ff_girl mysql512]# cp support-files/my-huge.cnf /etc/my512.cnf
并且修改如下部分。
[client]
