说明

登录MySQL查看字符集

修改mycnf文件中的字符集键值

重启mysql服务

再查看字符集

解决Linux MySql中文乱码问题

登录MySQL查看字符集

mysql> show variables like 'character%';
+--------------------------+----------------------------+
| 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/ |
+--------------------------+----------------------------+
8 rows in set (0.00 sec)

初始状态character_set_database和character_set_server的默认字符集是latin1。

修改my.cnf文件中的字符集键值

my.cnf文件在etc/mysql/路径下，打开my.cnf可以看到

!includedir /etc/mysql/conf.d/
!includedir /etc/mysql/mysql.conf.d/

大致意思是配置文件包含 那个目录下的配置文件，于是进到conf.d文件夹，看到mysql.cnf打开发现里面只有一个空标记[mysql]，我们不修改这个文件，打开另外一个文件夹mysql.conf.d，看到mysqld.cnf，打开这个文件，把character-set-server=utf8放在[mysqld]最后

[mysqld]
pid-file    = /var/run/mysqld/mysqld.pid
socket      = /var/run/mysqld/mysqld.sock
datadir     = /var/lib/mysql
log-error   = /var/log/mysql/error.log
character-set-server=utf8

# By default we only accept connections from localhost
bind-address    = 127.0.0.1
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

重启mysql服务

修改完成后，service mysql restart重启mysql服务就生效。网上说[mysqld]字段与[mysql]字段是有区别的，有兴趣可以查查。

再查看字符集

使用SHOW VARIABLES LIKE ‘character%’;查看，编码修改成功。

mysql> show variables like 'character%';
+--------------------------+----------------------------+
| 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/ |
