mysql的四種啟動方式

標籤：qt

mysql的四種啟動方式:

1、mysqld

啟動mysql伺服器:./mysqld --defaults-file=/etc/my.cnf --user=root

用戶端串連:

mysql --defaults-file=/etc/my.cnf

or

mysql -S /tmp/mysql.sock

2、mysqld_safe

啟動mysql伺服器:./mysqld_safe --defaults-file=/etc/my.cnf --user=root &

用戶端串連:

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

啟動mysql伺服器:service mysql.server {start|stop|restart|reload|force-reload|status}

用戶端串連: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;

啟動mysql伺服器:./mysqld_multi --defaults-file=/etc/my.cnf start 3306-3307

關閉mysql伺服器:mysqladmin shutdown
