Mysql8

ERROR 1410 (42000): You are not allowed to create a user with GRANT

mysql8 caching_sha2_password trouble

trouble Authentication plugin 'caching_sha2_password'

php artisan command:init-all-permission#初始化导致问题

Authentication plugin 'caching_sha2_password' cannot be loaded

  PDO::__construct(): The server requested authentication method unknown to the client [caching_sha2_password]  

shooting

建用户  这个试过可以的 mysql8 新用户和授权

create user 'live'@'%' identified by 'effsdf7';
#把mysql8 默认安全比较高的 caching_sha2_password改为 mysql_native_password,其实不是一个好的做法
ALTER USER 'live'@'%' IDENTIFIED WITH mysql_native_password BY 'effsdf7';

grant select,insert,update,delete on *.* to 'live'@'%';

flush privileges;刷新权限

授权  good  比较细的权限分授权 

如：grant select,insert,update,delete on *.* to 'liveapp'@'%';

grant select,insert,update,delete on `live-`.* to 'lcphp'@'172.16.1.7';


原因

 MySQL8.0新特性——默认使用caching_sha2_password作为身份验证插件 


| %         | cfbapp    | caching_sha2_password |  新的比较安全的
| %         | liveapp   | mysql_native_password    老的 改成这个为了php73
