##### 解决方案如下： #####

调小ilde连接数，

Config config = new Config();
    config.useSingleServer().setAddress("redis://192.168.0.100:6379");
    //加入下面一行代码即可
    config.useSingleServer().setConnectionMinimumIdleSize(10);
    RedissonClient redisson = Redisson.create(config);

##### 分析产生原因 #####

根据错误提示可以看出是32个连接中只成功了23个，猜测连接池太大了，尝试减少连接数之后发现可行。  
我的 redis-server运行环境：

系统：flymeOS 6
    手机型号：mx 6T（600元左右的手机）
    app ：termux

由于 redis 是运行在手机termux中的，手机的配置相比主机肯定差不少，猜测承受不了太多连接，不过只是为了学习方便，我不需要太多连接，可以随身携带。

##### 其他 #####

关于termux 的使用在我的其他博客里有涉及。
