CentOS查看和修改MySQL字符集

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

+--------------------------+----------------------------+
| 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

[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

+--------------------------+----------------------------+
| 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/ |
+--------------------------+----------------------------+
