我是靠谱客的博主落寞煎饼，最近开发中收集的这篇文章主要介绍CentOS 7下MySQL5.6的修改字符集编码为UTF8（解决中文乱码问题），觉得挺不错的，现在分享给大家，希望可以做个参考。

一、登录MySQL查看用SHOW VARIABLES LIKE ‘character%’;下字符集，显示如下：

 
    ? 
   
         + 
         --------------------------+----------------------------+ 
        
         | Variable_name | Value | 
        
         + 
         --------------------------+----------------------------+ 
        
         | character_set_client | utf8 | 
        
         | character_set_connection | utf8 | 
        
         | character_set_database | latin1 | 
        
         | character_set_filesystem | 
         binary 
         | 
        
         | character_set_results | utf8 | 
        
         | character_set_server | latin1 | 
        
         | character_set_system | utf8 | 
        
         | character_sets_dir | /usr/share/mysql/charsets/ | 
        
         + 
         --------------------------+----------------------------+

character_set_database和character_set_server的默认字符集还是latin1。

二、最简单的完美修改方法，修改mysql的 /etc/my.cnf 文件中的字符集键值（注意配置的字段细节）：

1、在[mysqld]字段里加入character-set-server=utf8，如下：
 
[mysqld]
port = 3306
socket = /var/lib/mysql/mysql.sock
character-set-server=utf8

修改完成后，sudo systemctl restart mysqld重启mysql服务就生效。

使用SHOW VARIABLES LIKE ‘character%’;查看，发现数据库编码全已改成utf8。

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