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

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