mysql innodb_log_buffer_size和 innodb_buffer_pool_size设置

mysql>  show variables like '%binlog_cache_size%';
+-----------------------+----------------------+
| Variable_name         | Value                |
+-----------------------+----------------------+
| binlog_cache_size     | 131072               |  
| max_binlog_cache_size | 18446744073709547520 |
+-----------------------+----------------------+


binlog_cache_size  128K:


mysql> show variables like '%log_buffer_size%';
+------------------------+---------+
| Variable_name          | Value   |
+------------------------+---------+
| innodb_log_buffer_size | 8388608 |  
+------------------------+---------+
1 row in set (0.00 sec)

innodb_log_buffer_size  =8M

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

调整这两个参数大小:

innodb_log_buffer_size=8M 用默认值就行

innodb_buffer_pool_size=1280M

mysql> show variables like '%innodb_log_buffer_size%';
+------------------------+----------+
| Variable_name          | Value    |
+------------------------+----------+
| innodb_log_buffer_size | 83886080 |
+------------------------+----------+
1 row in set (0.00 sec)

mysql> show variables like '%innodb_buffer_pool_size%';

| innodb_buffer_pool_size | 1342177280 |
