1.2 Demand

Nginx as a load balancer server, the user requests to arrive firstNginx, and then byNginxforwarding requests to a load configurationTomcatserver.

In the real world, Nginx and Tomcat servers are separate.

1.3 Add a local domain name to the host file

Using weight to configure load balancing, the weight defaults to 1, and the higher the weight, the more requests are processed.

node Description: added in the HTTP node: #定义负载均衡设备的 IP and device status   upstream myServer {  Server 127.0.0.1:9090 down;  Server 127.0.0.1:8080 weight=2;  server 127.0.0.1:6060;  Server 127.0.0.1:7070 BACKUP;&NBSP } Add Proxy_pass http://myServer under the server node that needs to use the payload; Upstream the status of each device: down indicates that the server before the single is temporarily not participating in load   Weight The larger the default is 1.weight, the greater the load weight.   Max_fails: The number of times a request fails is defaulted to 1. Returns the error   defined by the Proxy_next_upstream module when the maximum number of times is exceeded; Fail_timeout:max_fails Times failed, The time of the pause.   Backup: When all other non-backup machines are down or busy, request the backup machine. So the pressure on this machine is the lightest.
