Mysql8.0默认采用了新的caching_sha2_password的身份验证方式,此方式并不兼容常规的老的web服务接口,当然,不排除后面会出现。比如phpmyadmin5.0测试版已经出现兼容caching_sha2_password的模式。
为了继续维持我们常见的web连接的mysql身份验证方式,我们需要将默认的连接方式及root账户的连接方式恢复为旧的mysql_native_password方式。
1.使用root账户登入mysql,查询目前mysql的用户的身份验证方式。
select host,user,plugin,authentication_string from mysql.user;
显示如下:
mysql> select host,user,plugin,authentication_string from mysql.user; +-----------+------------------+-----------------------+------------------------------------------------------------------------+ | host | user | plugin | authentication_string | +-----------+------------------+-----------------------+------------------------------------------------------------------------+ | localhost | XXX | mysql_native_password | *6XXXXXXXXXXXXXXXXXXXX61 | | localhost | mysql.infoschema | caching_sha2_password | $A$005$THISISACOMBINATIONOFINVALIXXXXXXXXXXXXXBRBEUSED | | localhost | mysql.session | caching_sha2_password | $A$005$THISIXXXXXXXXXXXXXXXXXXXXXXXXXXSTNEVERBRBEUSED | | localhost | mysql.sys | caching_sha2_password | $A$005$THISISACOMBINATIONOFINVALIDSALTXXXXXXXXXXXXVERBRBEUSED | | localhost | root | mysql_native_password | *67FXXXXXXXXXXXXXXXXXXXXX961 | +-----------+------------------+-----------------------+------------------------------------------------------------------------+ 5 rows in set (0.00 sec) mysql>
可以在plugin看到身份插件验证方式.
更改root账户的验证方式为 mysql_native_password ,在mysql管理界面输入对应密码
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456'
刷新配置启用
FLUSH PRIVILEGES;
