The following brings you the Nginx environment, configuration and verification, hoping to give you some help in practical application. Load balancing involves a lot of things, and there are not many theories. There are many books on the Internet. Today, we will use the accumulated experience in the industry to do an answer.

1. Environment:

Frontend Nginx CVM: hostname: server1

IP:172.25.80.1 compilation and installation of nginx1..12

Backend tomcat:

Server2--ip:172.25.80.2 hostname: server2

Server3--ip:172.25.80.3 hostname: server3

2. Ngginx configuration:

User nginx

Worker_processes 1

Events {

Use epoll

Worker_connections 4096

}

Http {

Include mime.types

Default_type application/octet-stream

Sendfile on

Tcp_nopush on

Tcp_nodelay on

Server_tokens off

Keepalive_timeout 65

Server_names_hash_max_size1024

Gzip on

Gzip_proxied any

Gzip_min_length 1000

Gzip_comp_level 4

Gzip_types text/plain text/cssapplication/json application/x-javascript text/xml application/xmlapplication/xml+rss text/javascript

Gzip_static on

Upstream tomcat {# defines a cluster of tomcat servers. The following is the IP and port of the included servers

Server 172.25.80.2:8080

Server 172.25.80.3:8080

}

Server {

Listen 80; # defines a listening port

Server_name server1.a.com; # defines the name of the virtual host

Location / {

Root html/www; # default root directory for virtual host

Home page file type recognized by index index.jspindex.html index.htm; #

}

Location ~ *\. (jsp | do) ${# is not sensitive to lowercase regular matching, and requests ending with .jsp and dp are evenly distributed to the backend server cluster tomcat.

Proxy_pass http://tomcat; # forwards matching requests to the tomcat cluster

}

Location ~ *\. (jpg | png | gif | jgeg | pdf) ${# matches the file types defined in parentheses without case sensitivity

Proxy_pass http://172.25.80.1:8080; # forwarded to this server

}

}

Include html/*.conf; # reads the .conf file in this directory

}

3, verify:

1) visit server1.a.com:

2) 2) visit node5.a.com/index.jsp

Note: because it is clearly defined in the nginx configuration file that requests that exactly match the end of .jsp will be forwarded to the tomcat cluster, the request will not be completed natively in nginx, but will be forwarded to the server cluster. In addition, since two servers are defined in the cluster, user requests are assigned in turn, that is, the function of load balancing is realized:
