mysql占用内存过高400M＋

在阿里云上买了云服务器,1G的。跑 spring时没法抛数据库。跑数据库时根本运行不起tomcat。绞尽脑汁解决:

同事说１g跑spring的java还是省省把，，不过我就是跑起来了:

$ 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

从400M降到40M.算上java的400M

还能使
