CentOS 7下MySQL5.6的修改字符集编码为UTF8(解决中文乱码问题)

【From:】http://www.2cto.com/database/201311/255324.html
 
一、登录MySQL查看用SHOW VARIABLES LIKE ‘character%’;下字符集,显示如下:
 
?
1
2
3
4
5
6
7
8
9
10
11
12
+ --------------------------+----------------------------+
| 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。

| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
