Fedora CoreOS
在本指南中,您将在Fedora CoreOS上部署MyEMS。
前提
本指南介绍如何在Fedora CoreOS 37上安装MyEMS。硬件需求取决于所选数据库和连接到系统的设备数量。要在一台机器上运行MyEMS和MySQL,您至少需要4GB的RAM。
更新系统并安装工具:
rpm-ostree install git
rpm-ostree install python3
rpm-ostree install python3-pip
rpm-ostree install nginx
克隆源代码:
cd ~
git clone https://gitee.com/myems/myems
第1步 数据库
参考 Database
第2步 myems-api
- 安装 myems-api 服务:
sudo cp -r ~/myems/myems-api /var/myems-api
cd /var/myems-api
sudo pip install -r requirements.txt -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com
根据example.env创建.env文件,并根据需要编辑.env:
sudo cp /var/myems-api/example.env /var/myems-api/.env
sudo nano /var/myems-api/.env
将端口添加到防火墙:
sudo firewall-cmd --add-service=http --permanent
sudo firewall-cmd --add-port=8000/tcp --permanent
sudo firewall-cmd --reload
安装 systemd 配置文件:
sudo cp /var/myems-api/myems-api.service /etc/systemd/system/
sudo cp /var/myems-api/myems-api.socket /etc/systemd/system/
sudo cp /var/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#RHEL
启用nginx服务:
sudo systemctl enable nginx.service
- 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;
...
}
在目录 /etc/nginx/conf.d/ 下新建一个文件:
sudo nano /etc/nginx/conf.d/myems-admin.conf
编写如下指令, 如果myems-api服务运行在其它服务器上则用实际的地址替换 myems-api 默认地址 http://127.0.0.1:8000/
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'
## Replace the default myems-api url http://127.0.0.1:8000/ with actual url if the myems-api servcie hosted on different server
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 : 如果服务器无法连接到internet,请压缩myems/myems-admin文件夹并将其上传到服务器,然后将其解压缩到~/myems/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
“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
将端口添加到防火墙:
sudo firewall-cmd --add-service=http --permanent
sudo firewall-cmd --add-port=8001/tcp --permanent
sudo firewall-cmd --reload
重启nginx服务:
sudo systemctl restart nginx.service
如果您遇到“403 Forbidden”nginx错误,可以通过使用命令“sudo setforce 0”更改SELinx模式来修复它
第4步 myems-modbus-tcp
在此步骤中,您将安装myems-modbus-tcp服务。

在此步骤中,您将安装myems-web服务。
-
安装 NGINX 服务器 参考 http://nginx.org/en/linux_packages.html#Debian
-
配置 NGINX

In the 'http' section, add some directives:
http {
client_header_timeout 600;
client_max_body_size 512M;
gzip on;

gzip_proxied any;
gzip_types *;
gzip_vary on;
proxy_buffering off;
...
}
更新nginx默认conf文件:
sudo nano /etc/nginx/conf.d/default.conf
使用如下指令编写 ,如果myems-api服务托管在不同的服务器上,则使用实际的地址替换默认的myems-api地址http://127.0.0.1:8000/
server {
listen 80;
server_name myems-web;
location / {
root /var/www/myems-web;
index index.html index.htm;
# add try_files directive to avoid 404 error while refreshing pages
try_files $uri /index.html;
}
## To avoid CORS issue, use Nginx to proxy myems-api to path /api
## Add another location /api in 'server'
## replace the default myems-api url http://127.0.0.1:8000/ with actual url if the myems-api servcie hosted on different server
location /api {
proxy_pass http://127.0.0.1:8000/;
proxy_connect_timeout 75;
proxy_read_timeout 600;
send_timeout 600;
}
}
- 安装 MyEMS Web UI:
安装NodeJS:
sudo dnf install nodejs
修改配置文件:
从 https://mapbox.com 获取 mapboxToken 然后设置 showOnlineMap 为 true. 如果要关闭在线地图功能,设置 showOnlineMap 为 false
cd ~/myems/myems-web
sudo nano src/config.js
编译和压缩:
sudo npm i --unsafe-perm=true --allow-root --legacy-peer-deps
sudo npm run build
安装: 将文件上传到web服务器。 注意,以下路径应该与nginx.conf中配置的路径相同。
sudo mv build /var/www/myems-web
将端口添加到防火墙:
sudo firewall-cmd --add-service=http --permanent
sudo firewall-cmd --add-port=80/tcp --permanent
sudo firewall-cmd --reload
重启 NGINX
sudo systemctl restart nginx.service
如果您遇到“500内部服务器错误”nginx错误,可以通过使用命令“sudo setforce 0”更改SELinx模式来修复它
