mysql字符集问题

Question

我在solaris下面按照了mysql，然后修改/etc/my.cnf如下：
root@wlan5240-1 # more /etc/my.cnf
[client]
default-character-set=utf8
[mysqld] 
basedir = /usr/local/mysql 
datadir = /usr/local/mysql/data
default-character-set=utf8
重启mysql服务
cd /opt/mysql/mysql/bin
mysqld_safe &
然后进去 mysql -uroot -proot
mysql> show variables like 'collation_%';
+----------------------+-------------------+
| Variable_name        | Value             |
+----------------------+-------------------+
| collation_connection | utf8_general_ci   |
| collation_database   | latin1_swedish_ci |
| collation_server     | utf8_general_ci   |
+----------------------+-------------------+
3 rows in set (0.00 sec)mysql>  show variables like 'character_set_%';
+--------------------------+----------------------------------+
| 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     | utf8                             |
| character_set_system     | utf8                             |
| character_sets_dir       | /opt/mysql/mysql/share/charsets/ |
+--------------------------+----------------------------------+
8 rows in set (0.00 sec)
红色的部分为什么不是utf8_general_ci呢？

Answer 1

[mysqld]  
basedir = /usr/local/mysql  
datadir = /usr/local/mysql/data
default-character-set=utf8
character_set_database=utf8

Answer 2

楼上的，我按照你说的添加后，mysql无法启动，如下：
root@wlan5240-1 # 111206 23:04:49 mysqld_safe Logging to '/usr/local/mysql/data/wlan5240-1.err'.
111206 23:04:49 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/dataroot@wlan5240-1 # 111206 23:04:55 mysqld_safe mysqld from pid file /usr/local/mysql/data/wlan5240-1.pid ended

Answer 3

my.cnf如下：
root@wlan5240-1 # more /etc/my.cnf
[client]
default-character-set=utf8
[mysqld] 
basedir = /usr/local/mysql 
datadir = /usr/local/mysql/data
default-character-set=utf8
character_set_server=utf8
重启mysql后查看字符集
mysql> show variables like 'collation_%';
+----------------------+-------------------+
| Variable_name        | Value             |
+----------------------+-------------------+
| collation_connection | utf8_general_ci   |
| collation_database   | latin1_swedish_ci |
| collation_server     | utf8_general_ci   |
+----------------------+-------------------+
3 rows in set (0.01 sec)mysql> show variables like 'character_set_%';
+--------------------------+----------------------------------+
| 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     | utf8                             |
| character_set_system     | utf8                             |
| character_sets_dir       | /opt/mysql/mysql/share/charsets/ |
+--------------------------+----------------------------------+
8 rows in set (0.01 sec)
还不是utf8的

Answer 4

这个是你创建数据库时指定的数据库默认字符集，不会因为你改参数而变化。 你另外创建个数据库，然后USE这个数据库。这个参数自然就变了。
参考下贴中关于字符集的介绍。
