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:

[plain][/plain] view plaincopy

+--------------------------+----------------------------+

| 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][/plain] view plaincopy

[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

[plain][/plain] view plaincopy

+--------------------------+----------------------------+

| 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/share/mysql/charsets/ |
