统计数据库大小 

SELECT table_schema , sum( data_length + index_length ) / 1024 / 1024 "Data Base Size in MB"  FROM information_schema.TABLES GROUP BY table_schema;


统计表大小并排序 

SELECT table_name AS "Tables",

round(((data_length + index_length) / 1024 / 1024), 2) "Size in MB"

FROM information_schema.TABLES

WHERE table_schema = 'zabbix'

ORDER BY (data_length + index_length) DESC;



use zabbix;

truncate table history;

optimize  table history;

truncate table history_str;

truncate table history_uint;

该参数定义了数据缓冲区buffer pool大小,类似于oracle的db_cache_size

mysql> show global variables like 'innodb_buffer_pool_size';
+-------------------------+-----------+
| Variable_name           | Value     |
+-------------------------+-----------+
| innodb_buffer_pool_size | 134217728 |
+-------------------------+-----------+
1 row in set (0.00 sec)

那么如何设置该参数大小呢?首先查看运行时buffer pool相关数据指标:

mysql> show global status like 'Innodb_buffer_pool_pages_data';
+-------------------------------+-------+
| Variable_name                 | Value |
+-------------------------------+-------+
| Innodb_buffer_pool_pages_data | 314   |
+-------------------------------+-------+
1 row in set (0.00 sec)

mysql> show global status like 'Innodb_buffer_pool_pages_total';
+--------------------------------+-------+
| Variable_name                  | Value |
+--------------------------------+-------+
| Innodb_buffer_pool_pages_total | 8191  |
+--------------------------------+-------+
1 row in set (0.00 sec)

mysql> show global status like 'Innodb_page_size';
+------------------+-------+
| Variable_name    | Value |
+------------------+-------+
| Innodb_page_size | 16384 |
+------------------+-------+
1 row in set (0.00 sec)

上述三项指标的含义如下:

Innodb_buffer_pool_pages_data
The number of pages in the InnoDB buffer pool containing data. The number includes both dirty and
clean pages.

Innodb_buffer_pool_pages_total
The total size of the InnoDB buffer pool, in pages.

Innodb_page_size
InnoDB page size (default 16KB). Many values are counted in pages; the page size enables them to be
easily converted to bytes

计算Innodb_buffer_pool_pages_data/Innodb_buffer_pool_pages_total*100%
当结果 > 95% 则增加 innodb_buffer_pool_size, 建议使用物理内存的 75%
当结果 < 95% 则减少 innodb_buffer_pool_size, 
建议设置大小为: Innodb_buffer_pool_pages_data* Innodb_page_size * 1.05 / (1024*1024*1024)



Linux下面 my.cnf

innodb_buffer_pool_size = 10240M
