Ubuntu修改mysql默认编码的方法

ubuntu使用apt-get安装mysql后，server的默认编码是latin1，下面把server的编码修改成utf8。

编码相关信息：

1 2 3 4 5 6 7 8 9 10 11 12 13

mysql> show variables like 'character%'; +--------------------------+----------------------------+ | Variable_name            | Value                      | +--------------------------+----------------------------+ | character_set_client     | utf8                       | | character_set_connection | utf8                       | | character_set_database   | latin1                     | | character_set_filesystem | binary                     | | character_set_results    | utf8                       | | character_set_server     | latin1                     | | character_set_system     | utf8                       | | character_sets_dir       | /usr/share/mysql/charsets/ | +--------------------------+----------------------------+

可以看到character_set_database 和 character_set_server 的编码都是latin1。

修改mysql的编码

打开mysql的配置文件/etc/mysql/my.cnf

1	vim /etc/mysql/my.cnf

在[mysqld]里追加

1	character-set-server=utf8

保存后，重启mysql。

1	/etc/init.d/mysql restart

编码就正确了。

1 2 3 4 5 6 7 8 9 10 11 12 13

mysql> show variables like 'character%'; +--------------------------+----------------------------+ | 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/share/mysql/charsets/ | +--------------------------+----------------------------+

完成。
