+--------------------------+----------------------------+
8 rows in set (0.00 sec)

3.更改数据库的字符集

mysql> alter database opensips default character set ‘utf8‘;

4.创建数据库时指定字符集

mysql> create databse opensips character set utf8 collate utf8_general_ci; 

5.在mysql的配置文件/etc/my.cnf中指定创建的数据库的默认字符集
[mysqld]

default-character-set=utf8

datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

[mysqld_safe]
