摘要
ubuntu mysql 编码 latin1 utf8

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。

查看mysql和编码的信息

看下mysql的信息：

mysql> select version();
+-------------------------+
| version()               |
+-------------------------+
| 5.5.41-0ubuntu0.14.04.1 |
+-------------------------+

[/code]
编码相关信息：

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/ |
+--------------------------+----------------------------+

[/code]
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

vim /etc/mysql/my.cnf

[/code]
在[mysqld]里追加

character-set-server=utf8

保存后，重启mysql。

/etc/init.d/mysql restart

编码就正确了。

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。

如果character_set_client，character_set_connection等的编码也不是utf8，那么

在[client]里追加：

default-character-set=utf8

在[mysql]里追加：

default-character-set=utf8
