1. 在 /etc/mysql/my.cnf中添加
[mysqld]
character-set-server=utf8
[client]
default-character-set=utf8
2. 检查配置
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/share/mysql/charsets/ |
+--------------------------+----------------------------+
3. 如果选择数据库后，发现以上配置中某个uft8变成了latin,则要修改数据库配置。
