修改mysql的配置文件,然后添加:

root@bogon:logs# vi /etc/my.cnf
 
[mysqld]

lower_case_table_names=0
lower_case_table_names=1
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
 
max_connections=100
max_user_connections=100

Stopping mysqld:                                           [  OK  ]
Starting mysqld:                                           [  OK  ]
