navicat連接mysql服務端報10060錯誤解決過程如下

1、授權遠程登錄權限

mysql> update user set Host='%' where User = 'root';

Query OK, 1 row affected (0.00 sec)

Rows matched: 1? Changed: 1? Warnings: 0

flush privileges; 刷新權限

2、如果還連接不上，需要防火墻開啟3306端口，阿里云上也需要開啟允許連接3306端口

詳細參考之前訪問tomcat的配置

如果服務器安裝的是8.0的數(shù)據(jù)庫，連接時會出現(xiàn)Client does not support authentication protocol requested? by server；

原因：

mysql8 之前的版本中加密規(guī)則是mysql_native_password,而在mysql8之后,加密規(guī)則是caching_sha2_password,?

解決方法：.把mysql用戶登錄密碼加密規(guī)則還原成mysql_native_password.

更新用戶的密碼

?alter user 'root'@'localhost' identified with mysql_native_password by '123456'

? ? -> ;

Query OK, 0 rows affected (0.01 sec)

刷新權限：

mysql> flush privileges;

Query OK, 0 rows affected (0.00 sec)
