4、mysqld_multi

				?

									mkdir $MYSQL_BASE/data2

									cat <<-EOF>> /etc/my.cnf

									[mysqld_multi]

									mysqld = /usr/local/mysql/bin/mysqld_safe

									mysqladmin = /user/local/mysql/bin/mysqladmin

									user = mysqladmin

									password = mysqladmin

									[mysqld3306]

									port = 3306

									socket = /tmp/mysql3306.sock

									pid-file = /tmp/mysql3306.pid

									skip-external-locking

									key_buffer_size = 16M

									max_allowed_packet = 1M

									table_open_cache = 64

									sort_buffer_size = 512K

									net_buffer_length = 8K

									read_buffer_size = 256K

									read_rnd_buffer_size = 512K

									myisam_sort_buffer_size = 8M

									basedir = /usr/local/mysql

									datadir = /usr/local/mysql/data

									[mysqld3307]

									port = 3307

									socket = /tmp/mysql3307.sock

									pid-file = /tmp/mysql3307.pid

									skip-external-locking

									key_buffer_size = 16M

									max_allowed_packet = 1M

									table_open_cache = 64

									sort_buffer_size = 512K

									net_buffer_length = 8K

									read_buffer_size = 256K

									read_rnd_buffer_size = 512K

									myisam_sort_buffer_size = 8M

									basedir = /usr/local/mysql

									datadir = /usr/local/mysql/data2

									EOF

									#mysql -S /tmp/mysql3306.sock

									mysql>GRANT SHUTDOWN ON *.* TO 'mysqladmin'@'localhost' identified by 'mysqladmin' with grant option;

									#mysql -S /tmp/mysql3307.sock

									mysql>GRANT SHUTDOWN ON *.* TO 'mysqladmin'@'localhost' identified by 'mysqladmin' with grant option;

启动mysql服务器:./mysqld_multi --defaults-file=/etc/my.cnf start 3306-3307

关闭mysql服务器:mysqladmin shutdown
