龙蜥(Anolis) OS

在本指南中,您将在Anolis OS服务器上部署MyEMS。

前提

本指南介绍如何在Anolis OS 8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:

sudo dnf update
sudo yum install python39
sudo ln -sb /bin/python3.9 /bin/python3
sudo ln -sb /bin/pip3.9 /bin/pip3
sudo ln -sb /bin/python3.9 /bin/python
sudo ln -sb /bin/pip3.9 /bin/pip
sudo dnf install git

克隆源代码:

cd ~
git clone https://github.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 /myems-api
cd /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 /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 firewall-cmd --zone=public --add-port=8000/tcp --permanent
sudo firewall-cmd --reload

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#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
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

将端口添加到防火墙:

sudo semanage port -a -t http_port_t  -p tcp 8001
sudo firewall-cmd --zone=public --add-port=8001/tcp --permanent
sudo firewall-cmd --reload

重启nginx服务:

sudo systemctl restart nginx.service
提示

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。

sudo cp -r ~/myems/myems-modbus-tcp /myems-modbus-tcp
cd /myems-modbus-tcp
sudo pip install -r requirements.txt

将exmaple.ev文件复制到.env并修改.env文件:

sudo cp /myems-modbus-tcp/example.env /myems-modbus-tcp/.env
sudo nano /myems-modbus-tcp/.env

安装 systemd 服务:

sudo cp myems-modbus-tcp.service /lib/systemd/system/

启用服务:

sudo systemctl enable myems-modbus-tcp.service

启动服务:

sudo systemctl start myems-modbus-tcp.service

监控服务:

sudo systemctl status myems-modbus-tcp.service

查看日志:

cat /myems-modbus-tcp.log

第5步 myems-cleaning

在此步骤中,您将安装myems-cleaning服务。

sudo cp -r ~/myems/myems-cleaning /myems-cleaning
cd /myems-cleaning
sudo pip install -r requirements.txt -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com

将exmaple.ev文件复制到.env并修改.env文件:

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

安装systemd服务:

sudo cp /myems-cleaning/myems-cleaning.service /lib/systemd/system/

启用服务:

sudo systemctl enable myems-cleaning.service

启动服务:

sudo systemctl start myems-cleaning.service

监控服务:

sudo systemctl status myems-cleaning.service

查看日志:

cat /myems-cleaning.log

第6步 myems-normalization

在此步骤中,您将安装myems-normalization服务。

sudo cp -r ~/myems/myems-normalization /myems-normalization
cd /myems-normalization
sudo pip install -r requirements.txt -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com

将exmaple.ev文件复制到.env并修改.env文件:

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

安装systemd服务

sudo cp /myems-normalization/myems-normalization.service /lib/systemd/system/

启用服务:

sudo systemctl enable myems-normalization.service

启动服务:

sudo systemctl start myems-normalization.service

监控服务:

sudo systemctl status myems-normalization.service

查看日志:

cat /myems-normalization.log

第7步 myems-aggregation

在此步骤中,您将安装myems-aggregation服务。

sudo cp -r ~/myems/myems-aggregation /myems-aggregation
cd /myems-aggregation
sudo pip install -r requirements.txt -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com

将exmaple.ev文件复制到.env并修改.env文件:

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

安装systemd服务

sudo cp /myems-aggregation/myems-aggregation.service /lib/systemd/system/

启用服务:

sudo systemctl enable myems-aggregation.service

启动服务:

sudo systemctl start myems-aggregation.service

监控服务:

sudo systemctl status myems-aggregation.service

查看日志:

cat /myems-aggregation.log

第8步 myems-web

在此步骤中,您将安装myems-web服务。

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;
...

}

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 module list nodejs
sudo dnf module reset nodejs:16/common
sudo dnf module install nodejs:16/common

如有必要,检查并更改配置文件:

cd ~/myems/myems-web
sudo nano src/config.js

如果 'node -v' 返回 'v16.xx.xx', 在package.json 文件中的start和build命令参数重删除 '--openssl-legacy-provider'

sudo nano package.json
  ...
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
...

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 semanage port -a -t http_port_t  -p tcp 80
sudo firewall-cmd --zone=public --add-port=80/tcp --permanent
sudo firewall-cmd --reload

重启 NGINX

sudo systemctl restart nginx
提示

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
