进入mysql console:
输入
mysql>show variables like 'character%';
+--------------------------+-----------------------------------------------------+
| Variable_name | Value |
+--------------------------+-----------------------------------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | utf8 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | /usr/local/mysql-5.1.30-osx10.5-x86/share/charsets/ |

如果有的项目不是utf8，我们需要进行设置
编辑/etc/my.cnf，如果没有该文件，从mysql的安装目录的support-files copy一个my-small.cnf到/etc下，更名为my.cnf
sudo cp /usr/local/mysql/support-files/my-medium.cnf /etc/my.cnf
sudo vi /etc/my.cnf
加入红色字体的部分，保存后，重启mysql，重新执行show命令，将会发现应该都是utf8
注意default-character-set = utf8，等号两边要有空格，很重要，不然配置文件不生效
# Example MySQL config file for small systems.
#
# This is for a system with little memory (<= 64M) where MySQL is only used
# from time to time and it's important that the mysqld daemon
# doesn't use much resources.
#
# You can copy this file to
# /etc/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is /usr/local/mysql/data) or
# ~/.my.cnf to set user-specific options.
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.
# The following options will be passed to all MySQL clients
