mysql字符集笔记

查看数据库字符集
mysql> show variables like '%char%';
+--------------------------+----------------------------------+
| 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/local/mysql/share/charsets/ |
+--------------------------+----------------------------------+

修改Mysql字符集为UTF-8的方法：在/etc/my.cnf对应如下配置段加入相应命令。
[client]字段里加入default-character-set=utf8
[mysqld]字段里加入character-set-server=utf8
[mysql]字段里加入default-character-set=utf8
然后重启MySQL服务即可。
