Centos Django Mysql 支持emoji表情

1.更改 /etc/mysql/my.cnf, 添加如下内容:

[client]
default-character-set = utf8mb4
[mysql]
default-character-set = utf8mb4
[mysqld]
character-set-client-handshake = FALSE
character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci
init_connect='SET NAMES utf8mb4'

2.重启mysql

service mysqld status

3.查看msy编码

SHOW VARIABLES WHERE Variable_name LIKE 'character_set_%' OR Variable_name LIKE 'collation%';

5.修改数据库编码

ALTER DATABASE 数据库名（自行替换） CHARACTER SET = utf8mb4 COLLATE utf8mb4_unicode_ci;

DATABASES = {  
    'default': {  
        #'ENGINE': 'sqlite3', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.  
        'ENGINE': 'django.db.backends.mysql',  
        #'NAME': '/opt/media/session.db',                      # Or path to database file if using sqlite3.  
        'NAME': DATABASE_NAME,  
        'USER': 'root',                      # Not used with sqlite3.  
        'PASSWORD': DATABASE_PASSWORD,                  # Not used with sqlite3.  
        'HOST': DATABASE_HOST,                      # Set to empty string for localhost. Not used with sqlite3.  
        'PORT': DATABASE_PORT,                      # Set to empty string for default. Not used with sqlite3.  
       'OPTIONS': {'charset':'utf8mb4'}, 
    },  
}
