一、找到Nginx的配置文件nginx.conf
1.查看Nginx的实际调用配置文件
ps aux|grep nginx
root 352 0.0 0.0 2468624 924 ?? S 10:43上午 0:00.08 nginx: worker process
root 232 0.0 0.0 2459408 532 ?? S 10:43上午 0:00.02 nginx: master process /usr/sbin/nginx -g daemon on;
root 2345 0.0 0.0 2432772 640 s000 S+ 1:01下午 0:00.00 grep nginx
可以看出Nginx路径为 /usr/sbin/nginx
2.查看Nginx配置文件路径
使用Nginx的 -t 参数进行配置检查，即可知道实际调用的配置文件路径及是否调用有效。
/usr/sbin/nginx -t
nginx: the configuration file etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
二、进入nginx.conf文件，找到包含conf.d的目录路径并进行配置
可以看到：
include /etc/nginx/conf.d/*.conf;
将Pyscada文档中下载的配置文件移动进/etc/nginx/conf.d目录中：（也可在下载时就进行移动）
pyscada.conf所在路径
cd /etc/nginx/sites-enabled
mv pyscada.conf /etc/nginx/conf.d
进入pyscada.conf对其进行修改
cd /etc/nginx/conf.d
nano pyscada.conf
因为没有https的证书，同时也不需要使用到https，使用http即可，因此对内容进行删除，将文件修改至以下：
# pyscada.conf
# the upstream component nginx needs to connect to
upstream app_server {
server unix:/tmp/gunicorn.sock fail_timeout=0; # for a file socket
#server 127.0.0.1:8000 fail_timeout=0; # for a file socket
}
# configuration of the server
server {
listen 8081;
listen [::]:8081;
server_name _; # substitute your machine's IP address or FQDN
#return 301 https://$server_name$request_uri;
#return 301 https://$host$request_uri;
# Django media
location /media {
alias /var/www/pyscada/http/media; # your Django project's media files - amend as required
}
location /static {
alias /var/www/pyscada/http/static; # your Django project's static files - amend as required
}
location /measurement {
alias /home/pyscada/measurement_data_dumps; # to support download of measurement files via admin backend - amend as required
}
location / {
# checks for static file, if not found proxy to app
try_files $uri @proxy_to_app;
}
location @proxy_to_app {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://app_server;
}
}
此处因为8080端口已被openplc占用，因此换作8081端口，读者可视自身情况进行修改。修改结束重启Nginx。
nginx -s reload
到这里pyscada配置结束。根据官方文档进行后续配置，最后输入以下命令打开pyscada。
sudo systemctl start pyscada
打开浏览器输入localhost:8081，进入pyscada登录界面，输入用户名及密码即可成功登录使用。
