这将把你的/phpmyadmin更改为/otherfilename，并且适用于LEMP服务器（nginx）

1. sudo apt更新
2. sudo apt安装程序phpmyadmin
   1.用户名：/usr/share/phpmyadmin/var/www/html/phpmyadmin
   1.检查你的网址https://server_domain_or_IP/phpmyadmin
   1.更新您的vhost

location /phpmyadmin {
    root /usr/share/;
    index index.php;

    try_files $uri $uri/ =404;
    location ~ ^/phpmyadmin/(doc|sql|setup)/ {
        deny all;
    }

    location ~ /phpmyadmin/(.+\.php)$ {
        fastcgi_pass unix:/run/php/php7.2-fpm.sock;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
        include snippets/fastcgi-php.conf;
    }
}

1. sudo服务nginx重新启动
   1.再次检查你的网址到访问phpmyadmin
2. cd/变量/网址/html/
3. ls-l
   1.检查phpmyadmin文件
   1.创建符号文件

sudo mv phpmyadmin otherfilename

1. ls-l
   1.检查您新符号文件并在5中更改您的虚拟主机

location /otherfilename{
    root /var/www/html/;
    index index.php;
    try_files $uri $uri/ =404;

    location ~ ^/otherfilename/(doc|sql|setup)/ {
        deny all;
    }

    location ~ /otherfilename/(.+\.php)$ {
        fastcgi_pass unix:/run/php/php7.2-fpm.sock;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
        include snippets/fastcgi-php.conf;
    }
}

1. sudo服务nginx重新启动
   1.检查你的新网址https://server_domain_or_IP/otherfilename

请查看/etc/nginx/site-available/default，您需要在其中添加location /phpmyadmin

还有另一种方法，使用alias指令代替root。

location /ddh73d1re1tp01hpn8sbceryzzzcp1 {
            alias /usr/share/phpmyadmin;
            index index.php index.html index.htm;

            location ~ ^/ddh73d1re1tp01hpn8sbceryzzzcp1/(.+\.php)$ {
                     try_files $uri =404;
                     fastcgi_pass unix:/run/php/php8.1-fpm.sock;
                     fastcgi_index index.php;
                     fastcgi_param SCRIPT_FILENAME $request_filename;
                     include /etc/nginx/fastcgi_params;
}
