Ubuntu下修改MySQL預設資料庫編碼

MySQL
主要設定檔位置:/etc/mysql/my.cnf.

資料庫表檔案夾:/var/lib/mysql/,在Ubuntu Linux中相當於Windows下MySQL的date檔案夾

登入MySQL,執行編碼顯示:

show variables like 'character%';

+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | latin1 |
| character_set_connection | latin1 |
| character_set_database | latin1 |
| character_set_filesystem | binary |
| character_set_results | latin1 |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+

修改MySQL預設資料庫的編碼

需要編輯my.cnf檔案,Windows可以直接用Ｍysql Server Instance Config Wizard 進行設定

sudo gedit /etc/mysql/my.cnf

找到[client] 添加:

default-character-set=utf8 //預設字元集為utf8

找到[mysqld] 添加:

//預設字元集為utf8
default-character-set=utf8
//設定串連mysql資料庫時使用utf8編碼，以讓mysql資料庫為utf8運行
init_connect='SET NAMES utf8' 

修改好後,重新啟動mysql 即可.

查詢一下show variables like 'character%';
