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

关闭mysql服务器:mysqladmin shutdown
