Ubuntu修改mysql預設編碼
阿新 • • 發佈：2019-02-01
修改mysql的配置檔案,使資料庫與伺服器作業系統的字符集設定一致。
vi /etc/my.cnf 設定(如果沒有發現這個檔案，就新建1個)
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
default-character-set=utf8 (增加的關鍵一句,使得資料庫預設以utf8儲存)
當然，修改後，要重啟資料庫。
再次用mysql -u root -p命令進入資料庫系統，用SHOW VARIABLES LIKE 'character_set_%';命令檢視到如下內容：
+--------------------------+-----------------------------------------------------------------------+
| Variable_name | Value |
+--------------------------+-----------------------------------------------------------------------+
| character_set_client | latin1 |
| character_set_connection | latin1 |
| character_set_database | utf8
| character_set_filesystem | binary |
| character_set_results | latin1 |
| character_set_server | utf8
| character_set_system | utf8 |
| character_sets_dir | /usr/local/mysql-5.1.20-beta-linux-i686-glibc23/share/mysql/charsets/ |
+--------------------------+-----------------------------------------------------------------------+
發現關鍵專案已經用了utf8，但這樣還不夠，還要保證客戶端也是用utf8的字符集來操作的
登入的時候，要用以下命令：mysql --default-character-set=utf8 -u root -p
再次用SHOW VARIABLES LIKE 'character_set_%';命令檢視，結果變成了：
+--------------------------+-----------------------------------------------------------------------+
| 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 |
| character_sets_dir | /usr/local/mysql-5.1.20-beta-linux-i686-glibc23/share/mysql/charsets/ |
+--------------------------+-----------------------------------------------------------------------+
這樣才能保證客戶端所發命令都是基於utf8格式的，比如說建立資料庫和表，預設就會以utf8編碼，而無須再次指定。
