mysql中插入中文显示乱码的问题（backbox）

进入MySQL终端，输入以下命令show variables like 'character%';

显示以下：
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 | /usr/share/mysql/charsets/ |
+————————–+—————————-+

加黑部分就是不能正常显示的缘由,须要将编码格式更改成utf8格式，修改过程以下：

修改MySQL的配置文件

vim /etc/mysql/conf.d/mysql.cnf

修改以下

[mysql]
no-auto-rehash
default-character-set=utf8
[mysqld]
socket = /var/run/mysqld.sock
port =3306
character-set-server=utf8

重启：service mysql restart()

改完以后

+--------------------------+----------------------------+
| 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/ |
+--------------------------+----------------------------+
8 rows in set (0.01 sec)

mysql> select * from php0;
+----+-----------------------+--------+
| id | msg                   | intime |
+----+-----------------------+--------+
|  1 | 咱们都有一个家        | NULL   |
+----+-----------------------+--------+
1 row in set (0.00 sec)

这样就能够显示中文，不会有乱码（注：可是以前建立的数据库仍是不能插入中文数据）
