It is possible to install phpmyadmin on raspberry 64 bit and it even was not difficult in my case. I am running several hp-laptops with openSuse Tumbleweed and some Raspberries. On the latest Raspberry 3 B + I 64bit raspbian buster light, kde plasma Desktop. Linux raspi10 5.10.60-v8+ #1449 SMP PREEMPT Wed Aug 25 15:01:33 BST 2021 aarch64 GNU/Linux I am using nginx 1.14.2 with fastcgi (not using 'sock') and php 8.0.10 (php-fpm). I downloaded 'composer' first. (Use apt or aptitude for that). After that go to https://docs.phpmyadmin.net/en/latest/setup.html Look for the shell command

composer create-project phpmyadmin/phpmyadmin

它将在当前目录中安装一个完整的目录'phpmyadmin'。 移动到/var/lib/并根据nginx.conf中的设置设置user:group权限 在我的例子中: chown -R www-data:www-data /var/lib/phpmyadmin

创建一个符号链接到/srv/www/public或/var/www/html或任何你的服务器正在寻找的东西。 您可以向phpMyAdmin添加第二个名为phpMyAdmin的符号链接 确保nginx.conf中的根指令相应设置。

我的nginx配置在我的所有机器上(几乎)是相同的。 它现在非常紧凑。 这是最简单的方法。所有进一步的服务器和功能可以稍后添加。 /etc/nginx/sites-enabled没有条目 /etc/nginx/vhosts.d中没有任何内容 从php.ini中的一个池开始。为了配置它，谷歌一点和测试 通过检查php-fpm的状态。

在尝试了所有方法之后，我想出了这个解决方案

当默认情况下PHP 7.0 FPM未启用时，将出现此错误。

要在Apache2中启用PHP 7.0 FPM，运行:

 sudo 2enmod proxy_fcgi setenvif
 sudo a2enconf php7.0-fpm
 systemctl restart apache2

如果您使用的是php7.4，在上面的命令中输入7.4而不是7.0。

重新安装mcrypt模块对我有用。

$sudo apt-get install php5-mcrypt
$sudo php5enmod mcrypt

听起来你的配置好像有问题，下面是一些你可以检查的东西:

Make sure that PHP is installed and running correctly. This may sound silly, but you never know. An easy way to check is to run php -v from a command line and see if returns version information or any errors. Make sure that the PHP module is listed and uncommented inside of your Apache's httpd.conf This should be something like LoadModule php5_module "c:/php/php5apache2_2.dll" in the file. Search for LoadModule php, and make sure that there is no comment (;) in front of it. Make sure that Apache's httpd.conf file has the PHP MIME type in it. This should be something like AddType application/x-httpd-php .php. This tells Apache to run .php files as PHP. Search for AddType, and then make sure there is an entry for PHP, and that it is uncommented. Make sure your file has the .php extension on it, or whichever extension specified in the MIME definition in point #3, otherwise it will not be executed as PHP. Make sure you are not using short tags in the PHP file (<?), these are not enabled on all servers by default and their use is discouraged. Use <?php instead (or enable short tags in your php.ini with short_open_tag=On if you have code that relies on them). Make sure you are accessing your file over your webserver using an URL like http://localhost/file.php not via local file access file://localhost/www/file.php

最后，查看PHP手册以获得更多的设置技巧。

检查你为php安装的所有包，使用:

yum list installed | grep remi

在你的机器上安装所有相关的php包，尤其是php-devel。

我发现了另一个导致这个问题的问题，并且已经解决了它。我不小心将脚本保存为UTF-16编码。PHP5似乎不能识别<?PHP标签默认为16位编码。
