hello ~ Hello, everyone , In the previous expansion, I briefly introduced DevOps , From the beginning of this article, we have entered into the automated deployment project . Some of the projects we wrote earlier , They are manually added step by step , It seems too cumbersome , How we have 1000 A project , This cannot be deployed manually （ It will be tiring si One of the ）, So the official for efficiency , Launched  DevOps.

One 、DevOps brief introduction

DevOps Is a series of practices and tools , You can make IT And the software development team Process automation . among , With the increasing popularity of agile software development , Continuous integration (CI) and Continuous delivery (CD) It has become an ideal solution in this field . stay CI/CD In workflow , Each set is verified by automated construction , Including coding 、 Release and test , So as to help developers find integration errors in advance , Teams can also quickly 、 Security 、 Reliably deliver internal software to the production environment .

Two 、 Shangyitong project goes to the cloud

Here is the server 、 client 、 And gateway ; After the deployment of server and client , Send a request to the gateway , The gateway sends each request to the microservice

Project framework

3、 ... and 、sentinel Deploy

Before going to the cloud, we must first deploy middleware , image  Nacos、MySQL、Redis It has been deployed before , So next, deploy the rest .

 

1、Sentinel

It is used for flow protection

In the application load ——> Create a service in the service （ Set the basic information 、 Container mirror 、 Mount storage 、 Advanced settings and other settings ）

Four 、mongo Deploy

  alike , In the application load ——> Select a template to create in the application , Click the deployment （ Set the basic information 、 Application configuration
Wait for settings ）, For Hou Hao's convenient visit , You can expose the port number .

  Then specify the workload to create the service （ Setting basic information 、 Service settings 、 Advanced settings ）, After deployment, we can use a tool to test whether the deployment is complete （MongoDB Compass Software for ）, Connect , No problem

 

mysq| Data initialization

Using tools （SQLyog） Connected to the mysql , Will we use sql The statement is imported and run .

5、 ... and 、 Production environment configuration extraction

Project default rules

• Each microservice item , In the production environment , Will automatically get Microservice name -prod.yml As your own core configuration file
• Each microservice item , In the production environment , The default is to use 8080 port

Create a  service-cmntprod.yml Change the address of all middleware to the address of our production , The same for every microservice （Sentinel、MongoDB、RabbitMQ、Redis etc. ） Such operations are required , Configured in the back  deploy.yaml file
