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>
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
