    2、mysqld_safe
    启动mysql服务器:./mysqld_safe --defaults-file=/etc/my.cnf --user=root &
    客户端连接:
    mysql --defaults-file=/etc/my.cnf

    chkconfig --add mysql.server
    启动mysql服务器:service mysql.server {start|stop|restart|reload|force-reload|status}
    客户端连接:同1、2
    
    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
