1）修改字符集为UTF8
#vi /etc/my.cnf
在[client]下面添加 default-character-set = utf8
在[mysqld]下面添加 character_set_server = utf8
修改完重启：#service  mysqld  restart 


2）增加错误日志
#vi /etc/my.cnf
在[mysqld]下面添加：
log-error = /usr/local/mysql/log/error.log
general-log-file = /usr/local/mysql/log/mysql.log
修改完重启：#service  mysql  restart 


3) 设置为不区分大小写，linux下默认会区分大小写。
#vi /etc/my.cnf
在[mysqld]下面添加：
lower_case_table_name=1
修改完重启：#service  mysql  restart  


chkconfig mysqld on
