Ubuntu下MysqlServer默認編碼的設置
配置
以下列出了Linux下比較流行發行版Ubuntu的兩個LTS版本基本配置，其他發行版可以參考其中的參數，配置文件路徑可能有差異。
Ubuntu 14.04 環境下的配置
Ubuntu 14.04 下只需要修改一個文件: /etc/my.cnf
[mysql]
default-character-set=utf8
[client]
default-character-set=utf8
[mysqld]
collation-server = utf8_generic_ci
init-connect='SET NAMES utf8'
character-set-server = utf8
Ubuntu 16.04 環境下的配置
Ubuntu 16.04 中MysqlServer配置被分成了兩個文件來維護，依次將相應的配置區(section)放到對應的配置文件里就可以了。
/etc/mysql/conf.d/mysql.cnf
[mysql]
default-character-set=utf8
[client]
default-character-set=utf8
/etc/mysql/mysql.conf.d/mysqld.cnf
[mysqld]
init-connect='SET NAMES utf8'
character-set-server = utf8
驗證修改結果
配置完成后重啟數Mysql服務器，檢查數據庫編碼
mysql> show variables like '%char%';
配置正確的話會將所有編碼設置成utf8
+--------------------------+----------------------------+
| Variable_name | Value |

| character_set_database | utf8 |
