MAMP MySQL 无法识别 OSX 中的 my.cnf 值

Question

尝试永久使用 UTF8，但无法让 MAMP 安装的 MySQL 识别 my.cnf 值。

MAMP 版本 2.0.5 (2.0.5)

MySQL 5.5.9

my.cnf 文件：

[client]
default-character-set=utf8

[mysql]
default-character-set=utf8

[mysqld]
default-character-set=utf8
default-collation=utf8_general_ci
collation_server=utf8_general_ci
character_set_server=utf8
init-connect='SET NAMES utf8'

文件位置：

/Applications/MAMP/Library/Conf/

启动时的 MySQL 变量：

mysql> show variables where variable_name LIKE '%char%' OR variable_name LIKE '%colla%';
+--------------------------+--------------------------------------------+
| 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       | /Applications/MAMP/Library/share/charsets/ |
| collation_connection     | utf8_general_ci                            |
| collation_database       | latin1_swedish_ci                          |
| collation_server         | latin1_swedish_ci                          |
+--------------------------+--------------------------------------------+

在各种 db 之间切换会将 _database 值都转换为 utf8，但我似乎无法同时获得 _server 选项来反映 utf8 / utf8_unicode_ci：

use tsdb;

+--------------------------+--------------------------------------------+
| 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     | latin1                                     |
| character_set_system     | utf8                                       |
| character_sets_dir       | /Applications/MAMP/Library/share/charsets/ |
| collation_connection     | utf8_general_ci                            |
| collation_database       | utf8_general_ci                            |
| collation_server         | latin1_swedish_ci                          |
+--------------------------+--------------------------------------------+

试过

set global character_set_server = utf8;

等等，但它没有重新启动。

这是我第一次弄乱 my.cnf，所以我确定我忽略了一些基本的东西。 my.cnf 中是否缺少信息，语法是否错误？还是顺序重要？

谢谢。

在 my.cnf 文件的 [mysqld] 组中包含 skip-character-set-client-handshake，一切似乎都已正确配置，UTF8 直通。我仍然不确定为什么[client] 组中的default-character-set=utf8 没有带到这里，但我是一个新手，所以希望有人可以在那里阐明。 您必须在 Applications/MAMP/conf 和 IN MAMP Pro 中创建 my.cnf，然后在 File > Edit Template > MySQL my.cnf 下进行更改。

我的.cnf：

# The MySQL server
[mysqld]
skip-character-set-client-handshake
collation_server=utf8_unicode_ci
character_set_server=utf8

结果：

mysql> SHOW VARIABLES WHERE variable_name LIKE '%char%' OR variable_name LIKE '%colla%';
+--------------------------+--------------------------------------------+
| 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       | /Applications/MAMP/Library/share/charsets/ |
| collation_connection     | utf8_unicode_ci                            |
| collation_database       | utf8_unicode_ci                            |
| collation_server         | utf8_unicode_ci                            |

这也解决了为什么mysqladmin的变量在使用SHOW VARIABLES时与mysql的不同。
