mysql 默认client server 字符集是 latinl，为防止有乱码，全部都改为utf-8
1.查看mysql的字符集
mysql> show variables like '%char%';
+--------------------------+----------------------------------+
| Variable_name | Value |
+--------------------------+----------------------------------+
| character_set_client | latinl |
| character_set_connection | latinl |
| character_set_database | utf8 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | latinl |
| character_set_system | utf8 |
| character_sets_dir | /usr/local/mysql/share/charsets/ |
+--------------------------+----------------------------------+
8 rows in set (0.02 sec)
2.编辑参数文件 my.cnf,里面加入以下参数,修改后重启服务
[root@zw oradata]# vi /etc/my.cnf
[client]
default-character-set=utf8
[mysqld]
character-set-server=utf8
3.再次查看mysql的字符集
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/ |
+--------------------------+----------------------------------+
可以看到现在都是utf-8了
