我有docker的lamp和phpmyadmin。
我的设置如下
localhost:80 -> web localhost:8081 -> phpmyadmin 但是如果我访问phpmyadmin
它显示了这样的错误 mysqli_real_connect(): (HY000/1045): Access denied for user 'root'@'172.27.0.4' (using password: YES) 这是我的背景。 docker-compose.yml ```

Copy configuration

COPY etc /etc/

Copy main script

COPY run.sh /run.sh
RUN chmod u+rwx /run.sh

Calculate download URL

ENV VERSION 4.8+snapshot
ENV URL https://files.phpmyadmin.net/snapshots/phpMyAdmin-${VERSION}-all-languages.tar.gz
LABEL version=$VERSION

Download tarball, verify it using gpg and extract

RUN set -ex;
curl --output phpMyAdmin.tar.gz --location $URL;
tar xzf phpMyAdmin.tar.gz;
rm -f phpMyAdmin.tar.gz phpMyAdmin.tar.gz.asc;
mv phpMyAdmin-$VERSION-all-languages /www;
rm -rf /www/setup/ /www/examples/ /www/test/ /www/po/ /www/composer.json /www/RELEASE-DATE-$VERSION;

chown -R root:nobody /www;
find /www -type d -exec chmod 750 {} ; ;
find /www -type f -exec chmod 640 {} ;

Add directory for sessions to allow session persistence

RUN mkdir /sessions
&& mkdir -p /www/tmp
&& chmod -R 777 /www/tmp

We expose phpMyAdmin on port 80

EXPOSE 80

ENTRYPOINT [ "/run.sh" ]
CMD ["phpmyadmin"]
