客户提供了MySQL的环境，但是不支持中文，
通过以下命令查看了MySQL的字符集
连接上mysql服务，输入以下命令
mysql>show variables like 'character_set%';
显示如下：
01.+--------------------------+----------------------------+
02.| Variable_name | Value |
03.+--------------------------+----------------------------+
04.| character_set_client | latin1 |
05.| character_set_connection | latin1 |
06.| character_set_database | latin1 |
07.| character_set_filesystem | binary |
08.| character_set_results | latin1 |
09.| character_set_server | latin1 |
10.| character_set_system | utf8 |
11.| character_sets_dir | /usr/share/mysql/charsets/ |
12.+--------------------------+----------------------------+
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | latin1 |
| character_set_connection | latin1 |
| character_set_database | latin1 |
| character_set_filesystem | binary |
| character_set_results | latin1 |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
为了让MySQL支持中文，需要把字符集改变成UTF8，
方法如下：
1. 打开etc/my.cnf
2. 修改成如下内容，保存
[plain] view plaincopyprint?
01.[client]
02.port=3306
03.socket=/var/lib/mysql/mysql.sock
04.default-character-set=utf8
05.
06.[mysqld]
07.datadir=/var/lib/mysql
08.socket=/var/lib/mysql/mysql.sock
09.user=mysql
10.# Disabling symbolic-links is recommended to prevent assorted security risks
11.symbolic-links=0
12.character-set-server=utf8
13.
14.[mysql]
15.no-auto-rehash
16.default-character-set=utf8
17.
18.[mysqld_safe]
19.log-error=/var/log/mysqld.log
20.pid-file=/var/run/mysqld/mysqld.pid
[client]
port=3306
socket=/var/lib/mysql/mysql.sock
default-character-set=utf8
[mysqld]
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
character-set-server=utf8
[mysql]
no-auto-rehash
default-character-set=utf8
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
3. 重启mysql服务：service mysqld restart
再次查看mysql编码，已经更新成如下信息
01.+--------------------------+----------------------------+
02.| Variable_name | Value |
03.+--------------------------+----------------------------+
04.| character_set_client | utf8 |
05.| character_set_connection | utf8 |
06.| character_set_database | utf8 |
07.| character_set_filesystem | binary |
08.| character_set_results | utf8 |
09.| character_set_server | utf8 |
10.| character_set_system | utf8 |
11.| character_sets_dir | /usr/share/mysql/charsets/ |
12.+--------------------------+----------------------------+
