答案1:
在20.04中,如果您使用php5.,则phpmyadmin软件包会有些混乱。phpmyadmin提供了与php5.5 +兼容的PMA4.9.5,但取决于php-phpmyadmin-motranslator> = 5.0,与php7.1 +兼容。
只需从github下载4.9.5 zip,将其解压缩到您的webroot下的某个位置即可。
答案2:
问题-ubuntu 20.04使用mysql v8和caching_sha2_password。使用php7.4一切正常。但是当您使用php5.6时,会遇到两个错误
要解决这个问题,我们需要将以下代码添加到/etc/mysql/my.cnf
[client]
default-character-set=utf8
[mysql]
default-character-set=utf8
[mysqld]
collation-server = utf8_unicode_ci
character-set-server = utf8
default-authentication-plugin=mysql_native_password
你还需要通过以下代码,更新mysql用户认证方法
alter user 'username'@'localhost' identified with mysql_native_password by 'password';
