Nginx reverse proxy configuration example

Environment:

Nginx1: 192.168.68.41

2017at1: 192.168.68.43

Tomcat2: 192.168.68.45

Nginx is installed in many tutorials on the Internet. I installed nginx with yum.

Configure nginx:

Vim/etc/nginx/CONF. d/Default. conf

Content:

# Compresses the data stream gzip on; gzip_min_length 1000; gzip_types text/plain text/CSS application/X-JavaScript; # sets the Server list of Server Load balancer # The weigth parameter indicates the weight, the higher the weight, the higher the probability of being allocated to upstream Hello {server 192.168.68.43: 8080 Weight = 1; server 192.168.68.45: 8080 Weight = 1;} server {# listening port 80 listen 80; SERVER_NAME localhost; # Set the address location/nginxstatus {stub_status on; access_log on; auth_basic "nginxstatus"; auth_basic_user_file htpasswd;} # match the address ending with JSP, tomcat's webpage file ends with JSP location/{Index.

Start:

Nginx

Exit:

Nginx-s quit

After nginx is started, access http: // 192.168.68.41/test/

Will be navigated to http: // 192.168.68.43: 8080/test/and http: // 192.168.68.45: 8080/test/

This achieves load balancing and avoids spof.
