docker执行完，浏览80端口，安装完成后执行如下代码

开启redis，在config/config.php文件中,$CONFIG = array里添入以下代码

    'overwritehost' => 'ncloud.lhyshome.com:443',
    'overwriteprotocol' => 'https',
    'overwrite.cli.url' => 'https://ncloud.lhyshome.com:443',
    'memcache.locking' => '\\OC\\Memcache\\Redis',
    'redis' =>
        array (
            'host' => '192.168.0.212', 
            'port' => 6379,
            'dbindex' => 0,
        ),

trusted_domains里修改为

0 => 'ncloud.lhyshome.com',
