查看和修改MySql6.0數據庫編碼(Linux版本)

首先查看安裝好的mysql編碼，Mysql提供命令查看環境參數的工具。

[root@localhost ~]# /usr/local/bin/mysqladmin variables
這樣就列出了很多參數，不過我們只找和字符編碼有關的參數說明

| 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/local/share/mysql/charsets/         |
| collation_connection            | latin1_swedish_ci                        |
| collation_database              | latin1_swedish_ci                        |
| collation_server                | latin1_swedish_ci                        |

上面這些纔是和mysql字符編碼有關的。
可以看到默認mysql編碼是latin1，那麼我們下面就對它修改成我們想要的。

==========================================
下面是修改成utf8編碼過程（如果要修改gbk，把utf8換成gbk就可以）

在/etc目錄下的my.cnf文件（此文件相當於windows中的.ini文件） 

使用 vi 進去修改  vi /etc/my.cnf

找到在[mysqld]這一行下面，加入一句default-character-set=utf8即可！ 
保存退出 然後 重啓 mysql 就可以了。很簡單吧 呵呵

一般，如果你是編譯安裝mysql ，建議你像我下面的做法
cp /usr/local/share/mysql/mysql.server /etc/init.d/mysqld

mysql 關閉的命令爲：/etc/init.d/mysqld stop

mysql 啓動的命令爲：/etc/init.d/mysqld start

我們再查看修改後的字符參數
#/usr/local/bin/mysqladmin variables

可以該命令列出的參數中參數如
| 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/share/mysql/charsets/         |
| collation_connection            | utf8_general_ci                          |
| collation_database              | utf8_general_ci                          |
| collation_server                | utf8_general_ci                          |

全部已經改成uft8，則配置編碼方式爲utf8成功！ 

好了，查看和修改 mysql 數據庫編碼就演示到這裏
