mysql设置字符集CHARACTER SET

Posted 2021-01-12 Neither Candidate

在 my.cnf 配置文件中设置相关选项，改变为相应的character set。

设置数据库编码(sudo vi /etc/mysql/my.cnf)：

[client]
default-character-set = utf8

[mysqld]
character-set-server = utf8
collation-server = utf8_general_ci

查看设置结果

更改my.cnf之前：

mysql> SHOW VARIABLES LIKE ‘%char%‘;
+--------------------------+---------------------------------------------------------------+
| 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/local/mysql-5.6.21-linux-glibc2.5-x86_64/share/charsets/ |
+--------------------------+---------------------------------------------------------------+

设置之后，重启mysql服务($ sudo service mysql restart)：

mysql> SHOW VARIABLES LIKE ‘%char%‘;
+--------------------------+---------------------------------------------------------------+
| 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                                                          |
