mysql的四种启动方式:

1、mysqld（现在很少直接用mysqld启动了，一般用mysqld_safe）

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

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=mysql&

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/mysql
(rpm安装之后系统自动帮你cp了，路径自己去find一下吧）

chkconfig --add mysql （add需要自己去手动添加）

启动mysql服务器:service mysql {start|stop|restart|reload|force-reload|status}
/etc/init.d/mysql start|stop

客户端连接:同1、2

4、mysqld_multi （管理多个服务器时候常用的）

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|report|stop 3306-3307

关闭mysql服务器:mysqladmin -uroot -p -P3306 shutdown
