django-vue-admin 使用Mariadb 连接提示Character set ‘utf8‘ is not a compiled character set解决

git 后，使用 python3 manage.py makemigrations 提示如下：

Character set 'utf8' is not a compiled character set and is not specified in the '/usr/share/mysql/charsets/Index.xml' file
!
Character set 'utf8' is not a compiled character set and is not specified in the '/usr/share/mysql/charsets/Index.xml' file

python3 manage.py migrate

按照网上说的，修改相应配置：

mariadb-secure-installation

设置MariaDB字符集. 需要设置4个文件my.cnf, client.cnf, mysql-clients.cnf, server.cnf.

1 vim /etc/my.cnf 增加以下内容

[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

2 vim /etc/my.cnf.d/client.cnf 在[client]后增加 default-character-set=utf8

[client]
default-character-set=utf8mb4

3 vim /etc/my.cnf.d/mysql-clients.cnf在[mysql]增加default-character-set=utf8mb4

[mysql]
default-character-set=utf8mb4

4 vim /etc/my.cnf.d/server.cnf 在[server]后增加character-set-server=utf8mb4

[server]
character-set-server=utf8mb4

 重启MariaDB, 连接数据库,检查字符集.

1 重启MariaDB

systemctl restart mariadb

2 连接数据库.

# 回车输入密码即可
mysql -uroot -hlocalhost -P3306 -p

3 检查字符集

show variables like "%character%";
show variables like "%collation%";

没什么卵用！

停下来分析了一下，是不是与pymqsql有关：

在dvadmin\system\_init_.py中加入下面两行：

import pymysql

pymysql.install_as_MySQLdb()

 

 顺利通过！
