1. ./configure --prefix=/home/mysql/mysql
2. make
3. make install
在 my.cnf中我设置 innodb_pool_buffer_size = 8G，但当我用命令"show variables like 'innodb_buffer_pool_size';时，结果为4G:
+-------------------------+------------+
| Variable_name | Value |
+-------------------------+------------+
| innodb_buffer_pool_size | 4093640704 |
+-------------------------+------------+
然后我在my.cnf中将 innodb_pool_buffer_size 修改为 5G，上面的结果变为：
+-------------------------+------------+
| Variable_name | Value |
+-------------------------+------------+
| innodb_buffer_pool_size | 1996488704 |
+-------------------------+------------+
不知道为什么？请高手指教！！
