[Nginx] Configuring NGINX load balancing
Run 2 Tomcat in this unit
Now you need to run two Tomcats, listen to different ports, let Nginx be loaded into load balancing.
Tomcat version:apache-tomcat-7.0.69-windows-x64.zip
To run two Tomcats in a machine, we must solve the conflict of the port, we only needD:\green\tomcat_cluster\apache-tomcat-7.0.69-server-1\conf\server.xmlinportwithredirectPortThe port modifies the different ports that do not occupy.
<Server port="8005" shutdown="SHUTDOWN">To turn off the port of the server listening.<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />, Port = "8080", HTTP connection listener port; redirectport = "8443", encountered an SSL request, the port requesting the jump.<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />, AJP listening ports and ports that have a SSL turn. Regarding AJP, I don't understand, please refer to:Summary and analysis of AJP protocol
Nginx load balancing configuration
Nginx version:nginx-1.10.1.zip
Nginx supports several formive equilibrium allocation:
- Round-robin
- Least-Connected
- IP hash (IP-HASH)
- Weight
Among them, IP hash load balancing is viscous, that is, the request of the same client in the session will always be assigned to a server. If you do not implement session sharing, you can use IP hash.
The following is the easiest way to configure:
Add the following configuration:
http {
......
upstream myweb_proxy {
server 127.0.0.1:18080;
server 127.0.0.1:28080;
}
......
server {
......
location /myweb {
proxy_pass http://myweb_proxy;
}
......
}
}Other configuration, reference:Using nginx as HTTP load balancer
