mysql的一些常用命令

a) 关闭数据库：shell>mysqladmin -h hostname -u username -ppassword shutdown
b) 复制数据库
i. Dump: shell>mysqldump -h hostname -u username –ppassword databasename > filename
ii. 导入到指定数据库：shell>mysql -h hostname -u username –ppassword databasename <filename (首先要建个同名的数据库)
c) 查看执行的sql：
i. Mysql>show processlist
+----+-------+-----------+-------+---------+------+-------+------------------+
| Id | User | Host | db | Command | Time | State | Info |
+----+-------+-----------+-------+---------+------+-------+------------------+
| 34 | price | localhost | price | Query | 0 | NULL | show processlist |
+----+-------+-----------+-------+---------+------+-------+------------------+
ii. 打开mysql的日志配置文件（windows下为my.ini;linux下为my.cnf）,然后打开其中的log=XX/XXX/filename，就可以打印所有执行过的sql日志。其它的还可以根据需要定制慢查询等日志
