Based on the web server’s operating system, you can set up Nginx in different ways. Here we will show you by installing the primary site at example.com domain name, while the proxied WordPress site is installed at abc.domain.com subdomain. Let’s see how to install and configure Nginx as a reverse proxy on the main server.
First, access your server’s terminal via SSH and update your distribution’s packages list and then install Nginx on your web server by using the command apt-get.
sudo apt update sudo apt install nginx
Now create a new virtual host file, to configure Nginx to proxy requests for domains hosted on Apache. Below is an example of using a nano editor to add the code, if you want you can choose any code editor.
sudo nano /etc/nginx/sites-available/example.com.conf
Next, you need to set Nginx directives so you can forward requests to Apache.
server {
listen 80;
server_name example.com www.example.com;
index index.php;
root /var/www/example.com/public #fallback for index.php
location / {
try_files $uri $uri/ /index.php?$query_string;
}location /abc {
proxy_pass http://abc.domain.com;proxy_http_version 1.1;
proxy_cache_bypass $http_upgrade;
# Proxy headers
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Forwarded-Port $server_port;
# Proxy timeouts
proxy_connect_timeout 60s;
proxy_send_timeout 60s;
proxy_read_timeout 60s;
}
Make sure you use your proxied website’s public IP address (or the URL) in the proxy_pass directive and also before you make any changes ensure the proxied website is installed and ready to be served.
Now you can save the virtual host file and activate the new virtual host.
sudo ln -s /etc/nginx/sites-available/example.com.conf /etc/nginx/sites-enabled/example.com.conf
Check for any configuration errors.
Check for any configuration errors
sudo nginx –t
If you didn’t find any error you can reload Nginx to see the changes.
sudo systemctl reload nginx
You can use the phpinfo() function to check to see if the PHP variables are loaded when you visit your proxied site.
