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.cnf or mysql -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.cnf or mysql -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/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
