mysql佔用內存過高400M＋

在阿里雲上買了雲服務器,1G的。跑 spring時沒法拋數據庫。跑數據庫時根本運行不起tomcat。絞盡腦汁解決:

同事說１g跑spring的java還是省省把，，不過我就是跑起來了:

$ sudo vi /etc/my.cnf

[mysqld]

# innodb_buffer_pool_size = 128M

#mysql memery config by youg @ 2014-11-10
table_open_cache=256
table_definition_cache=400


# basedir = .....
datadir = /usr/local/mysql/data
# port = .....
# server_id = .....
socket = /var/lib/mysql/mysql.sock

從400M降到40M.算上java的400M

還能使
