篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了mysql5.7 编码统一utf-8相关的知识,希望对你有一定的参考价值。
查看mysql数据库编码:
show variables like ‘character%‘;
mysql> show variables like ‘character%‘; +--------------------------+-------------------------------------------------+ | Variable_name | Value | +--------------------------+-------------------------------------------------+ | character_set_client | gbk | | character_set_connection | gbk | | character_set_database | latin1 | | character_set_filesystem | binary | | character_set_results | gbk | | character_set_server | latin1 | | character_set_system | utf8 | | character_sets_dir | E:\0Develop\mysql-5.7.15-winx64\share\charsets\ | +--------------------------+-------------------------------------------------+ 8 rows in set, 1 warning (0.00 sec) mysql>
可以看出database和server都采用了latin1编码,不支持中文,我们需要把它修改为utf-8。
除了这两个,其它的如下:
| 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 | E:\0Develop\mysql-5.7.15-winx64\share\charsets\
在mysql安装目录下,将 my-default.ini 复制一分保存为 my.ini
做如下修改:
主要看红色框里的内容:
[mysqld] character-set-server=utf8 collation-server=utf8_general_ci [mysql] default-character-set = utf8 [mysql.server] default-character-set = utf8 [mysqld_safe] default-character-set = utf8 [client] default-character-set = utf8
然后删除你当前的mysql服务,再重新注册mysql服务
注:一定要以管理员的权限运行dos命令,且cd到mysql安装目录下的bin目录,再注册mysql服务
C:\Windows\system32>sc delete mysql [SC] DeleteService 成功 C:\Windows\system32>e: cd E:\>cd E:\0Develop\mysql-5.7.15-winx64\bin E:\0Develop\mysql-5.7.15-winx64\bin>mysqld --install mysql --defaults-file="E:\0Develop\mysql-5.7.15-winx64\my.ini" The service already exists! The current server installed: E:\0Develop\mysql-5.7.15-winx64\bin\mysqld MySQL E:\0Develop\mysql-5.7.15-winx64\bin>net stop mysql MySQL 服务正在停止..服务名无效。 请键入 NET HELPMSG 2185 以获得更多的帮助。 E:\0Develop\mysql-5.7.15-winx64\bin>mysqld --install mysql --defaults-file="E:\0Develop\mysql-5.7.15-winx64\my.ini" Service successfully installed. E:\0Develop\mysql-5.7.15-winx64\bin>
结果
启动服务,查看编码:
C:\Windows\System32>net start mysql mysql 服务正在启动 . mysql 服务已经启动成功。 C:\Windows\System32>mysql -u root Welcome to the MySQL monitor. Commands end with ; or \g.

数据库实例编码设置:
mysql> show create database test; +----------+-----------------------------------------------------------------+ | Database | Create Database | +----------+-----------------------------------------------------------------+ | test | CREATE DATABASE `test` /*!40100 DEFAULT CHARACTER SET latin1 */ | +----------+-----------------------------------------------------------------+ 1 row in set (0.00 sec) mysql> alter database test default character set utf8; Query OK, 1 row affected (0.00 sec) mysql> show create database test; +----------+---------------------------------------------------------------+ | Database | Create Database | +----------+---------------------------------------------------------------+ | test | CREATE DATABASE `test` /*!40100 DEFAULT CHARACTER SET utf8 */ | +----------+---------------------------------------------------------------+ 1 row in set (0.00 sec) mysql>
