mysql Chinese garbled

The newly installed mysql server, because the default is latin encoding, often appears garbled under the linux server.

The coding design of mysql is relatively complex, involving the coding of servers, clients, databases, tables and table fields. To support Chinese, all encodings need to be set to UTF8.

1. Placement

vi /etc/my.cnf

[client]
default-character-set = utf8 #Client sets UTF8

[mysqld]
lower_case_table_names = 1 #Table names ignore case
character-set-server = utf8 #Server set UTF8
collation-server = utf8_general_ci #utf8 and case-insensitive correction rules

View table encoding:

mysql> show create table green_app_info;
+----------------+------------------------------------------------------------------------------------------------------------------------+
| Table          | Create Table                                                                                                                                                                                                             --------------+
| green_app_info | CREATE TABLE `green_app_info` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `apptype` int(11) NOT NULL,
  `appid` int(11) NOT NULL,
  `name` char(128) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1064 DEFAULT CHARSET=utf8 |
+----------------+------------------------------------------------------------------------------------------------------------------+
1 row in set

Set database encoding:

alter database greennet character set utf8;

Check out the encoding:

mysql> show variables like '%character_set_%';
+--------------------------+---------------------------------------------------------+
| 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-5.5.39-linux2.6-x86_64/share/charsets/ |
+--------------------------+---------------------------------------------------------+
8 rows in set

All are set to UTF8, and then /etc/init.d/mysqld restart restarts, inserting Chinese is normal.

2. PDM setting table coding

1. Set table options

Database --> Edit Current DBMS

General --> MySQL 5.0 --> Script --> Table --> Options

Add the following content, set the table ENGINE, character encoding, proofreading rules:

ENGINE = %s : list = BDB | HEAP | ISAM | InnoDB | MERGE | MRG_MYISAM | MYISAM, default = MYISAM
DEFAULT CHARSET = %s : list = utf8 | gbk, default = utf8
COLLATE = %s : list = utf8_bin | utf8_general_ci | gbk_bin | gbk_chinese_ci, default = utf8_bin

2. Set table characters

Double-click the table --> select UTF8 encoding
