Nginx Installation Deployment

Nginx Installation and Deployment

Opening Specified Ports or Disabling Firewall

View the ports that are already open:
```
firewall-cmd --list-ports
```

Open a specified port (e.g., port 80 for Nginx):

firewall-cmd --zone=public --add-port=80/tcp --permanent

Reload the firewall configuration:
```
firewall-cmd --reload
```
Confirm the opened ports:
```
firewall-cmd --list-ports
```
If needed, you can stop the firewall:
```
systemctl stop firewalld
```
Check the firewall status:
```
systemctl status firewalld
```

Installation and Deployment

Extract the Nginx installation package:

tar -zxvf nginx-1.16.1.tar.gz -C /usr/local/

Install dependencies:

yum install -y pcre pcre-devel
yum install -y zlib zlib-devel

Configure the installation path:

cd /usr/local/nginx-1.16.1
./configure --prefix=/usr/local/nginx

Compile Nginx:
```
make && make install
```
Configure local hostname resolution: Edit /etc/hosts and add an entry for your local domain:
```
ip cloud.whalealmg.com
```

Edit the Nginx configuration file:

server {
    listen 80;
    server_name cloud.whalealmg.com;

    location / {
        root /usr/local/nginx/html/dist/;
        index index.html index.htm;
        try_files $uri $uri/ /index.html;
    }

    location /filingAdmin/ {
        proxy_pass http://127.0.0.1:8000/;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Forwarded-Port $server_port;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }

    location ~ .*\.(js|css|jpg|jpeg|gif|png|ico|pdf|txt)$ {
        root /usr/local/nginx/html/dist/;
        index index.html index.htm;
    }

    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
        root html;
    }
}

Start the Nginx service:
```
/usr/local/nginx/sbin/nginx
```

Make sure to adjust paths, domain names, and other configurations as needed for your specific environment.
