Configuration

1. Environment description New platform Development Environment: saledev.linshimuye.com:81 Master Node: 10.10.15.163 Child Node 2VR 10.10.15.92 Child Node 3VR 10.10.15.147

Child node 4VR 10.10.15.176 Server permissions: root/lsmy@2019 dubbo-monitor: http://10.10.15.92:6090 dubbo-admin Administration background: http://10.10.15.179:60001 (user: root Password: root) reverse proxy plug-in address: http://10.10.15.179:8083 2, package release 2.1, front-end release: sh / data/package/script/cloud-front.sh 2.2, back-end release: backend package release can be packaged on node 1, node 2, node 3, first script package example: sh / data/webservers/script/dubbo_script_sit/order-dubbo.sh 2.4, Re-destroy the container at the primary node Create a container and destroy it. Example: kubectl delete-f / data/kubernetes/xpt-dev/dubbo/order-dubbo.yaml

Create a container example: kubectl create-f / data/kubernetes/xpt-dev/dubbo/order-dubbo.yaml

Forced destruction of containers

For example: kubectl delete pod [container name]-n=xpt-dev-- force-- grace-period=0 3, view log (master node operation) 3.1, view tomcat real-time log 3.2 on master node, view pod (container) name kubectl get pod-n=xpt-dev 3.3first, Print specific container logs according to name example: kubectl logs-f-- tail=100 order-dubbo-deployment-5994446f84-bl4kq-n=xpt-dev new destroy container kubectl delete-f / data/kubernetes/xpt-dev/dubbo/external-dubbo.yaml kubectl delete-f / data/kubernetes/xpt-dev/web/external.yaml create container kubectl create-f / data/kubernetes/xpt-dev/dubbo/external-dubbo.yaml kubectl create-f / data/kubernetes/xpt-dev/web/external .yaml compilation provider sh / data/webservers/script/dubbo_script_sit/external-dubbo.sh compile consumer sh / data/webservers/script/web_script_sit/external-web.sh view provider log tail-f-n100 / data/webservers_tomcat/tomcat-external-dubbo-13141/logs/localhost.2019-09-29.log view consumer log tail-f-n100 / data/webservers_tomcat/tomcat-external-web-10300/logs/localhost.2019 -09-29.log to view instance status kubectl get pod-o wide-n xpt-dev

Code hierarchical logic

Highlight the core logic: code that has nothing to do with the data checksum and the business logic of this method should not be put into the service as far as possible, but can be put into the manager layer.

Single responsibility: service layer code only provides services to controller and should not be called by other service; otherwise, circular dependencies, circular calls, etc., will occur, and the hierarchy will be unclear.

Exceptions are divided into business exceptions and system exceptions, which need to be handled separately, and different exception classes are assigned according to functional modules or systems to distinguish. For requests that do not conform to business logic, exceptions are thrown to interrupt the process and log.

Log, you can log where you want to if else, add, delete and modify it. If there is an exception in the log, you need to log the debug log for debugging information. Do not use Systen.out.print () to output data.

Management of local profiles:

Encapsulation of universal functions

Principle of module division

For others, see Ali specification.
