安装依赖包

首先安装gcc编译器，gcc有些系统版本已经默认安装，通过gcc -version查看，没安装的先安装gcc，不要缺少，否则有可能安装python出错，python3.7.0以下的版本可不装libffi-devel。

在云端节点，下载离线yum源，安装软件，命令如下：

[root@master ~]# curl -O http://mirrors.douxuedu.com/KubeEdge/python-kubeedge/gcc-repo.tar.gz

[root@master ~]# tar -zxvf  gcc-repo.tar.gz  

[root@master ~]# vi /etc/yum.repos.d/gcc.repo

[gcc]

name=gcc

baseurl=file:///root/gcc-repo

gpgcheck=0

enabled=1

[root@master ~]# yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel libffi-devel gcc

2.1.3 编译安装Python3.7

在云端节点下载python3.7等安装包，并进行解压编译，命令如下：

[root@master ~]# curl -O http://mirrors.douxuedu.com/KubeEdge/python-kubeedge/Python-3.7.3.tar.gz

[root@master ~]# curl -O http://mirrors.douxuedu.com/KubeEdge/python-kubeedge/volume_packages.tar.gz

[root@master ~]# mkdir /usr/local/python3 && tar -zxvf Python-3.7.3.tar.gz

[root@master ~]# cd Python-3.7.3/

[root@master Python-3.7.3]# ./configure --prefix=/usr/local/python3

[root@master Python-3.7.3]#  make && make install

[root@master Python-3.7.3]# cd /root

2.1.4 建立Python软链接

解压volume_packages压缩包，然后将编译后的python3.7软连接至/usr/bin目录下，并查看版本信息，命令如下：

[root@master ~]# tar -zxvf volume_packages.tar.gz

[root@master ~]# yes |mv volume_packages/site-packages/* /usr/local/python3/lib/python3.7/site-packages/

[root@master ~]# ln -s /usr/local/python3/bin/python3.7 /usr/bin/python3

[root@master ~]#  ln -s /usr/local/python3/bin/pip3.7 /usr/bin/pip3

[root@master ~]# python3 --version

Python 3.7.3

[root@master ~]# pip3 list

Package                  Version             

------------------------ --------------------

absl-py                  1.4.0               

aiohttp                  3.8.4               

aiosignal                1.3.1               

anyio                    3.7.0               

async-timeout            4.0.2               

asynctest                0.13.0

2.2 搭建MongoDB

2.2.1 搭建MongoDB

将mongoRepo.tar.gz软件包放到边侧节点中，然后进行解压，命令如下：

[root@kubeedge-node ~]# curl -O http://mirrors.douxuedu.com/KubeEdge/python-kubeedge/mongoRepo.tar.gz

[root@kubeedge-node ~]# tar -zxvf mongoRepo.tar.gz -C /opt/

[root@kubeedge-node ~]# vi /etc/yum.repos.d/mongo.repo

[mongo]

name=mongo

enabled=1

gpgcheck=0

baseurl=file:///opt/mongoRepo

在边侧节点安装mongodb，命令如下：

[root@kubeedge-node ~]# yum -y install mongodb*

安装完成后配置mongo，命令如下：

[root@kubeedge-node ~]# vi /etc/mongod.conf

#找到下面的字段然后进行修改

net:

  port: 27017

  bindIp: 0.0.0.0   #修改为0.0.0.0

修改完毕后，重启服务，命令如下：

[root@kubeedge-node ~]# systemctl restart mongod && systemctl enable mongod

验证服务，命令如下：

[root@kubeedge-node ~]# netstat -lntup |grep 27017

tcp        0      0 0.0.0.0:27017           0.0.0.0:*               LISTEN      10195/mongod

若出现27017端口，则MongoDB服务启动成功。

2.2.2 创建数据库

边侧节点登录MongoDB，创建数据库与集合，命令如下：

[root@kubeedge-node ~]# mongo

> show dbs

admin   0.000GB

config  0.000GB

local   0.000GB

> use edgesql

switched to db edgesql

> show collections

> db.createCollection("users")

{ "ok" : 1 }

> db.createCollection("ai_data")

{ "ok" : 1 }

> db.createCollection("ai_model")

{ "ok" : 1 }

> show collections

ai_data

ai_model

users

>

#按键盘上的Ctrl+D可退出

2.3 搭建H5前端

ydy_cloudapp_front_dist是编译后的前端H5程序，通过Web Server运行即可。

2.3.1 Linux运行H5前端

在边侧节点下载gcc-repo和ydy_cloudapp_front_dist压缩包并进行解压，配置Yum源并将解压后的文件拷贝至Nginx站点目录，命令如下：

[root@kubeedge-node ~]# curl -O http://mirrors.douxuedu.com/KubeEdge/python-kubeedge/gcc-repo.tar.gz

[root@kubeedge-node ~]# curl  -O http://mirrors.douxuedu.com/KubeEdge/python-kubeedge/ydy_cloudapp_front_dist.tar.gz

[root@kubeedge-node ~]# tar -zxvf gcc-repo.tar.gz

[root@kubeedge-node ~]# tar -zxvf ydy_cloudapp_front_dist.tar.gz  

[root@kubeedge-node ~]# vi  /etc/yum.repos.d/gcc.repo

[gcc]

name=gcc

baseurl=file:///root/gcc-repo

gpgcheck=0

enabled=1

[root@kubeedge-node ~]#  yum install -y nginx

[root@kubeedge-node ~]# rm -rf /usr/share/nginx/html/*

[root@kubeedge-node ~]# mv ydy_cloudapp_front_dist/index.html /usr/share/nginx/html/

[root@kubeedge-node ~]# mv ydy_cloudapp_front_dist/static/ /usr/share/nginx/html/

[root@kubeedge-node ~]# vi /etc/nginx/nginx.conf

#配置nginx反向代理，进入配置文件在文件下方找到相应的位置进行配置

server {

        listen       80;

        listen       [::]:80;

        server_name  localhost;

        root         /usr/share/nginx/html;

        # Load configuration files for the default server block.

        include /etc/nginx/default.d/*.conf;

        error_page 404 /404.html;

        location = /404.html {

        }

        location  ~ ^/cloudedge/(.*) {

          proxy_pass http://10.26.17.135:30850/cloudedge/$1;  

          proxy_set_header Host $host;

          proxy_set_header X-Real-IP $remote_addr;

          proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

          add_header 'Access-Control-Allow-Origin' '*';

          add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';

          add_header 'Access-Control-Allow-Headers' 'Authorization, Content-Type';

          add_header 'Access-Control-Allow-Credentials' 'true';

        }

        error_page 500 502 503 504 /50x.html;

        location = /50x.html {

        }

    }

[root@kubeedge-node ~]# nginx -t

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok

nginx: configuration file /etc/nginx/nginx.conf test is successful

[root@kubeedge-node ~]# systemctl restart nginx && systemctl enable nginx
