PDO::__construct(): The server requested authentication method unknown to the client [caching_sha2_password]
mysql8
以后,默认的密码模式改成 caching_sha2_password
,新的模式须要新的驱动,至少如今 pdo
/ navicat
还没给出,因此咱们仍是得切换成老的 mysql_native_password
模式。mysql
`mysql_native_password`:7.0 如下 `caching_sha2_password`:8.0 以上
一、my.cnf
配置默认的密码模式sql
[mysqld] default_authentication_plugin=mysql_native_password
二、更新帐号的密码模式ide
# 建立新的帐号 create user 'root'@'%' identified with mysql_native_password by '123456'; # 已存在的帐号 alter user 'root'@'%' identified with mysql_native_password by '123456';
三、若是你须要受权ui
# 受权也不能兼并建立帐号了,只能受权 grant all privileges on *.* to 'root'@'%' with grant option; flush privileges;
ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
密码复杂度验证策略致使的,关闭后设定便可编码
set global validate_password.policy=0; set global validate_password.length=6;
PDO::__construct(): Server sent charset (255) unknown to the client. Please, report to the developers
设定 mysql 服务的默认编码code
# Default Homebrew MySQL server config [client] default_character_set=utf8mb4 [mysql] default_character_set=utf8mb4 [mysqld] default_authentication_plugin=mysql_native_password character_set_server=utf8mb4 collation_server=utf8mb4_general_ci
一、my.conf 注释掉本地监听server
[mysqld] #bind_address=127.0.0.1
二、更新帐号的 host
ci
update mysql.user set host='%' where user='root';
