树莓派

在本指南中,您将把 MyEMS 部署到 Raspberry Pi 上。

先决条件

  • Raspberry Pi 5 or Raspberry Pi 4 Model B
  • Raspberry Pi OS (64-bit) A port of Debian Bookworm with the Raspberry Pi Desktop Released:2024-07-04

克隆源代码

sudo apt install git
sudo apt install pip
sudo apt install ufw
cd ~ && git clone https://gitee.com/myems/myems

第1步 数据库

  • 设置 MySQL 服务器
sudo apt update
sudo apt upgrade
sudo apt install mariadb-server

默认情况下,MySQL 安装时没有设置任何密码,这意味着您无需任何身份验证即可访问 MySQL 服务器。 运行以下命令以开始 MySQL 保护过程。

sudo mysql_secure_installation
Enter current password for root (enter for none): [Enter key or return key]
Switch to unix_socket authentication [Y/n] Y
Change the root password? [Y/n] Y
New password: !MyEMS1
Re-enter new password: !MyEMS1
Remove anonymous users? [Y/n] Y
Disallow root login remotely? [Y/n] n
Remove test database and access to it? [Y/n] Y
Reload privilege tables now? [Y/n] Y
  • 为 MyEMS 安装数据库架构和脚本。

参见 Database

第2步 myems-api

  • 安装 myems-api 服务:
sudo cp -r ~/myems/myems-api /myems-api
cd /myems-api

为了避免 'error: externally-managed-environment', 创建一个虚拟环境配置目录:

sudo python -m venv venv

开始使用虚拟环境

source venv/bin/activate

安装依赖库

sudo venv/bin/pip install -r requirements.txt

关闭虚拟环境

deactivate

根据example.env创建.env文件,并根据需要编辑.env:

sudo cp /myems-api/example.env /myems-api/.env
sudo nano /myems-api/.env

更改myems-api.service中的gunicorn路径为/myems-api/venv/bin/gunicorn

sudo nano /myems-api/myems-api.service
ExecStart=/myems-api/venv/bin/gunicorn -b 0.0.0.0:8000 --pid /run/myems-api/pid --timeout 600 --workers=4 app:api

将端口添加到防火墙:

sudo ufw allow 8000

安装 systemd 配置文件:

sudo cp /myems-api/myems-api.service /lib/systemd/system/
sudo cp /myems-api/myems-api.socket /lib/systemd/system/
sudo cp /myems-api/myems-api.conf /usr/lib/tmpfiles.d/

接下来启用这些服务,以便它们在启动时自动启动:

sudo systemctl enable myems-api.socket
sudo systemctl enable myems-api.service

启动服务:

sudo systemctl start myems-api.socket
sudo systemctl start myems-api.service

第3步 myems-admin

  • 安装 NGINX 服务器

参考 http://nginx.org/en/linux_packages.html#Debian

sudo apt install curl gnupg2 ca-certificates lsb-release debian-archive-keyring
curl https://nginx.org/keys/nginx_signing.key | gpg --dearmor | sudo tee /usr/share/keyrings/nginx-archive-keyring.gpg >/dev/null
gpg --dry-run --quiet --no-keyring --import --import-options import-show /usr/share/keyrings/nginx-archive-keyring.gpg
echo "deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] http://nginx.org/packages/debian `lsb_release -cs` nginx" | sudo tee /etc/apt/sources.list.d/nginx.list
echo -e "Package: *\nPin: origin nginx.org\nPin: release o=nginx\nPin-Priority: 900\n" | sudo tee /etc/apt/preferences.d/99nginx
sudo apt update
sudo apt install nginx
  • 配置 NGINX
sudo nano /etc/nginx/nginx.conf

在'http'段添加一些指令:

http {
client_header_timeout 600;
client_max_body_size 512M;
gzip on;
gzip_min_length 512;
gzip_proxied any;
gzip_types *;
gzip_vary on;
proxy_buffering off;

...
}

添加一个新的“server”部分,其指令如下:

  server {
listen 8001;
server_name myems-admin;
location / {
root /var/www/myems-admin;
index index.html index.htm;
}
## To avoid CORS issue, use Nginx to proxy myems-api to path /api
## Add another location /api in 'server' and replace demo address http://127.0.0.1:8000/ with actual url
location /api {
proxy_pass http://127.0.0.1:8000/;
proxy_connect_timeout 75;
proxy_read_timeout 600;
send_timeout 600;
}
}
  • 安装 myems-admin :
sudo mkdir /var/www
sudo cp -r ~/myems/myems-admin  /var/www/myems-admin
sudo chmod 0755 -R /var/www/myems-admin

检查配置文件,必要时进行更改:

sudo nano /var/www/myems-admin/app/api.js
警告

“upload”文件夹用于用户上传的文件。升级myems-admin时,请勿删除/移动/覆盖“upload”文件夹。

 /var/www/myems-admin/upload

sudo systemctl start nginx

将端口添加到防火墙:

sudo ufw allow 8001
