树莓派
在本指南中，您将把 MyEMS 部署到 Raspberry Pi 上。
先决条件
- Raspberry Pi 4 Model B (4GB RAM)
- Raspberry Pi OS Lite (64 bit)
克隆源代码
sudo apt install git
sudo apt install pip
sudo apt install ufw
cd ~
git clone https://github.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
sudo pip install -r requirements.txt
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
检查或更改myems-api.service和myems-api.socket中的侦听端口（默认值为8000）：
sudo nano /myems-api/myems-api.service
ExecStart=/usr/local/bin/gunicorn -b 0.0.0.0:8000 --pid /run/myems-api/pid --timeout 600 --workers=4 app:api
sudo nano /myems-api/myems-api.socket
ListenStream=0.0.0.0:8000
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
In the 'http' section, add some directives:
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
