Как правильно настрить phpmyadmin?

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

  location ~ ^/phpmyadmin/(.+\.php)$ {
    try_files $uri =404;
    root /usr/share/;
    proxy_pass http://127.0.0.1:81;
   }

  location ~* ^/phpmyadmin/(.+\.(jpg|jpeg|gif|css|png|js|ico|html|xml|txt))$ {
    root /usr/share/;
    expires 1M;
  }
}

location /phpmyadmin {
          root /var/www/apps/;
          index index.php index.html index.htm;

 location ~ ^/phpmyadmin/(.+\.php)$ {
          try_files $uri =404;
          root /var/www/apps/phpmyadmin/;
          proxy_pass $scheme://localhost:82;
          proxy_set_header X-Real-IP $remote_addr;
          proxy_set_header Host $host;
          proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      }
      location ~* ^/phpmyadmin/(.+\.(jpg|jpeg|gif|css|png|js|ico|html|xml|txt))$ {
          root /usr/share/;
      }
      }
      location /phpMyAdmin {
          rewrite ^/* /phpmyadmin last;
      }
