堡塔面板版本：正式版7.9.1
Nginx：1.20
PHP：7.4
MySQL：5.7
Redis：6.2.6

安装php7.4中的redis扩展

首先登录到Discuz论坛的后台图：
看到这里是支持的
https://www.bt.cn/bbs/data/attachment/forum/202205/23/152733yhubvbnvuhsjzpbu.png
然后打开Discuz的网站配置文件，
/www/wwwroot/189.dapaoit.com/config/config_global.php
// --------------------------CONFIG MEMORY--------------------------- //
$_config['memory']['prefix'] = 'gdBWWJ_';
$_config['memory']['redis']['server'] = '127.0.0.1';
$_config['memory']['redis']['port'] = 6379;
$_config['memory']['redis']['pconnect'] = 1;
$_config['memory']['redis']['timeout'] = '0';
$_config['memory']['redis']['requirepass'] = 'dapao666!';
$_config['memory']['redis']['serializer'] = 1;
$_config['memory']['memcache']['server'] = '';
$_config['memory']['memcache']['port'] = 11211;
$_config['memory']['memcache']['pconnect'] = 1;
$_config['memory']['memcache']['timeout'] = 1;
$_config['memory']['apc'] = '0';
$_config['memory']['apcu'] = '0';
$_config['memory']['xcache'] = '0';
$_config['memory']['eaccelerator'] = '0';
$_config['memory']['wincache'] = '0';
$_config['memory']['yac'] = '0';
$_config['memory']['file']['server'] = '';
$_config['memory']['redis']['server'] = '127.0.0.1';$_config['memory']['redis']['requirepass'] = 'dapao666!';
这两行，第一行是配置Redis的主机，第二行是配置Redis的密码（如果没有设置可以忽略）
配置好后，重新刷新下Dz论坛后台，可以看到有Redis的支持，打开，清理缓存的

打开Redis可视化工具，查看缓存的数据
