查看mysql數據編碼

登錄MySQL服務，查看mysql數據庫默認的編碼

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編碼，不支持中文，我們需要把它修改為utf-8。

除了這兩個，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\

設置mysql數據庫編碼

在mysql安裝目錄下，將 my-default.ini 復制一分保存為 my.ini?
做如下修改?

主要看紅色框里的內容

[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

然后刪除你當前的mysql服務，再重新注冊mysql服務?
注：一定要以管理員的權限運行dos命令，且cd到mysql安裝目錄下的bin目錄，再注冊mysql服務

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 服務正在停止..服務名無效。 請鍵入 NET HELPMSG 2185 以獲得更多的幫助。 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>

結果

啟動服務，查看編碼

C:\Windows\System32>net start mysql mysql 服務正在啟動 . mysql 服務已經啟動成功。C:\Windows\System32>mysql -u root Welcome to the MySQL monitor. Commands end with ; or \g.
