看来是我人品问题，220+升级内存失败，看来不是所有内存都支持。
发现是我没插紧，用力就好了。。

kodi链接失败？
把 api.themoviedb.org 翻墙看看
n1电视盒子或者安卓设备时间不对？
换个网络看看，说不定是连不上时间服务器。
如何添加公钥
wget -q ‘https://www.abc.com/key.txt’ -O – >>/root/.ssh/authorized_keys
oracle cloud机器修改主机名不起效
vi /etc/oci-hostname.conf
测试翻墙速度的一些文件

但是记得要看Openssl是不是在path里面
openwrt上安装you-get下载youtube视频
opkg update && opkg install git git-http
git clone git://github.com/soimort/you-get.git
cd you-get/
./setup.py install
you-get -i "https://www.youtube.com/watch?v=OdCeoQ2dYxE&t=34s"
esxi esir openwrt ikuai 安装注意点
客户机操作系统版本 其他5.X或更高linux64，可以选vmxnet3，获取更好的性能。
esxi 7 安装，启动的时候要输入参数，避免占用120空间
ikuai主路由 lede等做旁路由，会出现mac地址混乱的问题，要在主路由开通xx，旁路由启动yyy
安装windows 10，可能安装过程认不出网卡，先取消联网，装了vmtools之后就行了
esxi的管理口可以在启动后的黄黑屏幕设置，可以多选，选了以后就不能直通了
管理口设置的ip地址放一个网段，允许混杂，可以不插网线访问
esxi上的系统可以通过这个管理口虚拟的网卡做连通
如果用主路由+胖路由的方式上网，群晖设置外网访问upnp，说有两个路由器，把网关手工指定一下就行了
服务器安装推荐
安装lnmp
lnmp ssl add
强制所有的走https
include black.conf
传输文件 用管道
导入数据
安装v2ray
安装 monit
配置crontab
lnmp 安装exif opcache memcached
开启bbr
