未完成！！！

搭建Alexa 语音服务，这里用Raspberry、Ubuntu都是可以的，Centos没试过。

Raspberry、Ubuntu

注册亚马逊服务

有亚马逊账户就登陆，没有就注册：获取免费亚马逊开发者账户

然后设置各种东西，公司、地址、手机、邮箱等等。
登陆成功后会跳转到：https://developer.amazon.com/home.html

创建设备

安装安全配置文件
打开web浏览器，并访问以下网址 https://developer.amazon.com/lwa/sp/overview.html


这里也能看到Client ID和Client Secret。

配置环境

sudo apt-get update
sudo apt-get -y install git gcc cmake build-essential libsqlite3-dev libcurl4-openssl-dev libfaad-dev libsoup2.4-dev libgcrypt20-dev libgstreamer-plugins-bad1.0-dev gstreamer1.0-plugins-good libasound2-dev doxygen openssl
pip install commentjson

# 安装VNC（树莓派自带了，不用安装）
sudo apt-get install tightvncserver vlc-nox vlc-data

# 树莓派设置开机启动（Ubuntu不用设置，用systemctl）
mkdir -p /home/pi/.config/autostart
vim /home/pi/.config/autostart/tightvnc.desktop

# 输入以下文本:
[Desktop Entry]
Type=Application
Name=TightVNC
Exec=vncserver :1
StartupNotify=false

# 树莓派设置环境变量
vim .profile
export LD_LIBRARY_PATH=/usr/lib/vlc
export VLC_PLUGIN_PATH=/usr/lib/vlc/plugins


# 安装Nodejs
apt-get install -y nodejs nodejs-legacy npm

node -v
npm -v

# 安装jdk，maven(树莓派不用安装java)
apt-get install -y java
或
apt-get install -y openjdk-8-jre-headless openjdk-8-jdk-headless
apt-get install -y maven

java -version
javac -version
mvn -version

配置Alexa服务

# 项目地址：https://github.com/alexa/alexa-avs-sample-app
cd /root/
wget https://github.com/amzn/alexa-avs-raspberry-pi/archive/master.zip
unzip master.zip
cd /root/alexa-avs-sample-app-master/samples/javaclient
vim ssl.cnf
# 修改为
commonName              = CN          # CN=
countryName             = CN          # C=（这一项一定要2个字节）
stateOrProvinceName     = ST          # ST=
localityName            = L           # L=
organizationName        = O           # O=
organizationalUnitName  = OU          # OU=

chmod +x generate.sh
./generate.sh
1.提示输入product ID, 就是你在亚马逊设置的Product ID；比如：842632422
2.提示输入 serial number（dsn）, 自己设置一个编号（标识用的），比如123456
3.提示输入password, 你自己设置密码，例如: leolan (也可以留空)


vim config.json
# 修改以下几项
"productId":"你的Product ID：842632422",
    "dsn":"你设置的 serial number（dsn）：123456",
    "provisioningMethod":"companionService",   #这里填companionService
    "wakeWordAgentEnabled":false,
    "locale":"en-US",
    "companionApp":{
        "localPort":8443,
        "sslKeyStore":"/root/alexa-avs-sample-app-master/samples/javaclient/certs/server/jetty.pkcs12",
        "sslKeyStorePassphrase":"生成证书时设置的密码：leolan",
        "lwaUrl":"https://api.amazon.com"
    },
    "companionService":{
        "serviceUrl":"https://localhost:3000",
        "sslClientKeyStore":"/root/alexa-avs-sample-app-master/samples/javaclient/certs/client/client.pkcs12",

        "sslCaCert":"/root/alexa-avs-sample-app-master/samples/javaclient/certs/ca/ca.crt"
