How To Configure Nginx as a Reverse Proxy for Apache (Linux)

config_reverse_proxy

I will consider that you have three servers. First one with apache, second one with nginx server and third with bind.

1: Go to bind server (/etc/bind/zones/) and setup new A records to site that we will run. 
-     nginx5 IN A  192.168.0.1
-     apache5 IN A 192.168.0.2

2: Set vhost with new site for port 8080 (/etc/apache2/sites-available/)
<VirtualHost *:8080>
        ServerName apache5.mysite.com
        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/apache5
<Directory /var/www/apache5>
    Options Indexes ExecCGI FollowSymLinks
</Directory>
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
And upload some jpg file example.

3: Go to nginx server and configure vhost for new site (nginx5.mysite.com) (/etc/nginx/sites-available/)
server {
        listen 80;
        server_name  nginx5.mysite.com;
        access_log off;
        error_log  /var/log/apache2/yourdomain.com-error_log crit;
location / {
        client_max_body_size    10m;
        client_body_buffer_size 128k;

        proxy_send_timeout   90;
        proxy_read_timeout   90;
        proxy_buffer_size    128k;
        proxy_buffers     4 256k;
        proxy_busy_buffers_size 256k;
        proxy_temp_file_write_size 256k;
        proxy_connect_timeout 30s;
        proxy_pass   http://192.168.0.1:8080; //IP OF APACHE SERVER ON PORT 8080

        proxy_set_header   Host   $host;
        proxy_set_header   X-Real-IP  $remote_addr;
        proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
        }
}

4: Open http://nginx5.mysite.com and must see information about apache directory.
