mysql 5.6 分区_Mysql5.6—分区表及独享表空间

發(fā)布時間：2023/12/19 数据库 34 豆豆

生活随笔收集整理的這篇文章主要介紹了 mysql 5.6 分区_Mysql5.6—分区表及独享表空间小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.

1、先停止Mysql

[root@localhost~]#?/etc/init.d/mysqld?stop

Shutting?down?MySQL.[確定]

2、修改 /etc/my.cnf配置文件

[root@localhost~]#?vi?/etc/my.cnf

[mysqld]

innodb_file_per_table = 1

3、啟動Mysql

[root@localhost~]#?/etc/init.d/mysqld?start

Starting?MySQL..[確定]

4、連接到Mysql數(shù)據(jù)庫

[root@localhost~]#?mysql?-uroot?-p

Enter?password:

Welcome?to?the?MySQL?monitor.??Commands?end?with?;?or?\g.

Your?MySQL?connection?id?is?1

owners.

Type?'help;'?or?'\h'?for?help.?Type?'\c'?to?clear?the?current?input?statement.

mysql>?show?databases;

+-----------------------+--------+--------------------+---------+---------+

+-----------------------+--------+--------------------+---------+---------+

+-----------------------+--------+--------------------+---------+---------+

mysql>?use?dbmonitor;

5、創(chuàng)建分區(qū)表(history_text)：

mysql>create table history_text

(

id bigint(20) unsigned default null,

itemid bigint(20) unsigned default null,

clock int(11) default 0,

value text default null,

ns int(11) default 0,

index itemid_idx (itemid),

primary key(id,clock)

) engine=Innodb

partition by range (clock)

(

partition p1_201502 values less than (unix_timestamp('2015-03-01')),

partition p1_201503 values less than (unix_timestamp('2015-04-01')),

partition p1_201504 values less than (unix_timestamp('2015-05-01')),

partition p1_201505 values less than (unix_timestamp('2015-06-01')),

partition p1_201506 values less than (unix_timestamp('2015-07-01')),

partition p1_201507 values less than (unix_timestamp('2015-08-01')),

partition p1_201508 values less than (unix_timestamp('2015-09-01')),

partition p1_201509 values less than (unix_timestamp('2015-10-01')),

partition p1_201510 values less than (unix_timestamp('2015-11-01')),

partition p1_201511 values less than (unix_timestamp('2015-12-01')),

partition p1_201512 values less than (unix_timestamp('2016-01-01')),

partition p1_201601 values less than (unix_timestamp('2016-02-01')),

partition p1_201602 values less than (unix_timestamp('2016-03-01')),

partition p1_201603 values less than (unix_timestamp('2016-04-01')),

partition p1_201604 values less than (unix_timestamp('2016-05-01')),

partition p1_201605 values less than (unix_timestamp('2016-06-01')),

partition p1_201606 values less than (unix_timestamp('2016-07-01')),

partition p1_201607 values less than (unix_timestamp('2016-08-01')),

partition p1_201608 values less than (unix_timestamp('2016-09-01')),

partition p1_201609 values less than (unix_timestamp('2016-10-01')),

partition p1_201610 values less than (unix_timestamp('2016-11-01')),

partition p1_201611 values less than (unix_timestamp('2016-12-01')),

partition p1_other_all values less than maxvalue

);

mysql>alter table?history_text add primary key(id,clock);6、檢查數(shù)據(jù)數(shù)據(jù)庫配置參數(shù)是否生效。

[root@localhost?data]#?ll? ? 總計?10900348? ? drwx------?2?mysql?mysql???????4096?03-20?09:40?dbmonitor? ?-rw-rw----?1?mysql?mysql?7266631680?03-20?10:29?ibdata1? ? -rw-rw----?1?mysql?mysql????5242880?03-20?10:30?ib_logfile0? ? -rw-rw----?1?mysql?mysql????5242880?03-20?10:30?ib_logfile1? ? drwxr-xr-x?2?mysql?root????????4096?03-18?00:18?mysql? ? -rw-rw----?1?mysql?mysql??????27338?03-18?00:18?mysql-bin.000001[root@localhost~]#?cd?/usr/local/mysql/data/dbmonitor/[root@localhostdbmonitor]#?ll總計?5112-rw-rw----?1?mysql?mysql?131072?03-18?09:21?history_text#P#p1_201503.ibd-rw-rw----?1?mysql?mysql?131072?03-18?09:34?history_text#P#p1_201504.ibd-rw-rw----?1?mysql?mysql?131072?03-18?09:21?history_text#P#p1_201505.ibd-rw-rw----?1?mysql?mysql?131072?03-18?10:06?history_text#P#p1_201506.ibd-rw-rw----?1?mysql?mysql?131072?03-18?09:21?history_text#P#p1_201507.ibd-rw-rw----?1?mysql?mysql?131072?03-18?09:21?history_text#P#p1_201508.ibd-rw-rw----?1?mysql?mysql?131072?03-18?09:21?history_text#P#p1_201509.ibd-rw-rw----?1?mysql?mysql?131072?03-18?09:21?history_text#P#p1_201510.ibd-rw-rw----?1?mysql?mysql?131072?03-18?09:21?history_text#P#p1_201511.ibd-rw-rw----?1?mysql?mysql?131072?03-18?09:21?history_text#P#p1_201512.ibd-rw-rw----?1?mysql?mysql?131072?03-18?09:21?history_text#P#p1_201601.ibd-rw-rw----?1?mysql?mysql?131072?03-18?09:21?history_text#P#p1_201602.ibd-rw-rw----?1?mysql?mysql?131072?03-18?09:21?history_text#P#p1_201603.ibd-rw-rw----?1?mysql?mysql?131072?03-18?09:21?history_text#P#p1_201604.ibd-rw-rw----?1?mysql?mysql?131072?03-18?09:21?history_text#P#p1_201605.ibd-rw-rw----?1?mysql?mysql?131072?03-18?09:21?history_text#P#p1_201606.ibd-rw-rw----?1?mysql?mysql?131072?03-18?09:21?history_text#P#p1_201607.ibd-rw-rw----?1?mysql?mysql?131072?03-18?09:21?history_text#P#p1_201608.ibd-rw-rw----?1?mysql?mysql?131072?03-18?09:21?history_text#P#p1_201609.ibd-rw-rw----?1?mysql?mysql?131072?03-18?09:21?history_text#P#p1_201610.ibd-rw-rw----?1?mysql?mysql?131072?03-18?09:21?history_text#P#p1_201611.ibd-rw-rw----?1?mysql?mysql?131072?03-18?09:35?history_text#P#p1_other_all.ibd7、查看分區(qū)表。mysql> select table_name, partition_name from information_schema.partitions-> where table_schema='dbmonitor' and table_name='history_text';+--------------+----------------+| table_name ? | partition_name |+--------------+----------------+| history_text | p1_201503 ? ? ?|| history_text | p1_201504 ? ? ?|| history_text | p1_201505 ? ? ?|| history_text | p1_201506 ? ? ?|| history_text | p1_201507 ? ? ?|| history_text | p1_201508 ? ? ?|| history_text | p1_201509 ? ? ?|| history_text | p1_201510 ? ? ?|| history_text | p1_201511 ? ? ?|| history_text | p1_201512 ? ? ?|| history_text | p1_201601 ? ? ?|| history_text | p1_201602 ? ? ?|| history_text | p1_201603 ? ? ?|| history_text | p1_201604 ? ? ?|| history_text | p1_201605 ? ? ?|| history_text | p1_201606 ? ? ?|| history_text | p1_201607 ? ? ?|| history_text | p1_201608 ? ? ?|| history_text | p1_201609 ? ? ?|| history_text | p1_201610 ? ? ?|| history_text | p1_201611 ? ? ?|| history_text | p1_other_all ? |+--------------+----------------+22 rows in set (0.01 sec)8、插入數(shù)據(jù)測試分區(qū)表。

mysql> delimiter ;

mysql> call insert_test();

Query OK, 1 row affected (2 min 46.97 sec)

9、查看數(shù)據(jù)文件大小的變化。

注釋：發(fā)現(xiàn)只有單獨的表空間數(shù)據(jù)文件在增大，mysql的元數(shù)據(jù)文件不變化。

10、刪除分區(qū)表中的數(shù)據(jù)，減少數(shù)據(jù)文件的大小，清理空間。
