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
