废话不多说了，直奔主题了。

mysql的四种启动方式:

1、mysqld

启动mysql服务器:./mysqld --defaults-file=/etc/my.cnf --user=root

客户端连接:

mysql --defaults-file=/etc/my.cnformysql -S /tmp/mysql.sock

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.cnformysql -S /tm/mysql.sock

3、mysql.server

cp -v /usr/local/mysql/support-files/mysql.server /etc/init.d/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/data2cat <<-EOF>> /etc/my.cnf[mysqld_multi]mysqld = /usr/local/mysql/bin/mysqld_safemysqladmin = /user/local/mysql/bin/mysqladminuser = mysqladminpassword = mysqladmin[mysqld3306]port = 3306socket = /tmp/mysql3306.sockpid-file = /tmp/mysql3306.pidskip-external-lockingkey_buffer_size = 16Mmax_allowed_packet = 1Mtable_open_cache = 64sort_buffer_size = 512Knet_buffer_length = 8Kread_buffer_size = 256Kread_rnd_buffer_size = 512Kmyisam_sort_buffer_size = 8Mbasedir = /usr/local/mysqldatadir = /usr/local/mysql/data[mysqld3307]port = 3307socket = /tmp/mysql3307.sockpid-file = /tmp/mysql3307.pidskip-external-lockingkey_buffer_size = 16Mmax_allowed_packet = 1Mtable_open_cache = 64sort_buffer_size = 512Knet_buffer_length = 8Kread_buffer_size = 256Kread_rnd_buffer_size = 512Kmyisam_sort_buffer_size = 8Mbasedir = /usr/local/mysqldatadir = /usr/local/mysql/data2EOF#mysql -S /tmp/mysql3306.sockmysql>GRANT SHUTDOWN ON *.* TO 'mysqladmin'@'localhost' identified by 'mysqladmin' with grant option;#mysql -S /tmp/mysql3307.sockmysql>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
